Abstract

PROBLEM TO BE SOLVED: To solve a problem that much labor is required for searching a part to be browsed when browsing a structured document from a portable terminal because the structured document cannot be converted based on a segmenting object area before. SOLUTION: An object including information desired to browse in the structured document is designated previously and is registered in an object registering means 105. When a user tries to request browsing of the structured document by using the portable terminal 13 after this, a document obtaining means 101 obtains the requested structured document from a document source 11, and a document analyzing means 103 analyzes the structured document to detect the hierarchical structure of the object. An object specifying means 108 specifies an object including information to be displayed on the terminal 13 from the analyzing result of the object by the means 103 and the information registered in the means 105, and displays it on the terminal 13.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a structured document conversion system and a structured document conversion program, and more particularly, to analyzing a hierarchical structure of information in a structured document and preliminarily determining a portion that a user wants to view on a portable terminal. The present invention relates to a structured document conversion system for generating a registered part as a structured document in a format that can be viewed on a portable terminal, and a structured document conversion program for causing a computer to realize the structured document conversion system. .

2. Description of the Related Art With the spread of mobile terminals such as mobile phones and PDA terminals, the opportunity to browse web documents on the Internet with mobile terminals has increased. In general, a mobile terminal has a small screen size, a small display amount, and there may be a restriction on a displayable data format. Therefore, it is assumed that the mobile terminal is viewed on a terminal having a large screen size such as a personal computer (PC). When a created web document is displayed on a mobile terminal, it cannot be displayed, or even if it can be displayed, much effort is required to reach information desired by a user in the document.

Therefore, when browsing a web document created on the assumption of browsing on a terminal having a large screen size such as a PC, the web document is converted to be displayable on the portable terminal, and It is necessary to convert the web document so that the user can quickly reach a desired portion.

[0004] In addition, when browsing a web document on the Internet with a portable terminal, the user often accesses information in a data format that cannot be displayed on the portable terminal or is difficult to convert into a structured document. After a long wait, the mobile device will only display an error message. Therefore, while browsing web documents on a mobile device,
When accessing information that cannot be displayed on the mobile terminal, it is necessary that the browsing operation of the user is not hindered and that the information that could not be browsed can be quickly accessed later by another terminal.

[0005] Further, when a search engine used on a normal Internet is used when browsing with a portable terminal,
The title and URL (uniform resource l) of each search result
List of Internet addresses, simple information, etc. in the form of ocators), but if this is displayed on a terminal equipped with a display means with a limited amount of display information, the list of results is lost because the amount of information is too large. Would. Therefore, it is necessary to limit the search result to an appropriate amount of information and to convert the search result destination page so that the user can quickly reach a desired part.

Systems described in each of the publications, literature (Nikkei Electronics, No. 775 (July 31, 2000)), pages 57 to 6
2) is known. By using these conventional structured document conversion systems, it is possible to convert web documents created on the assumption of browsing on terminals with large screens such as PCs so that they can be viewed on mobile terminals.

[0007] Further, as a conventional technique relating to a method of accumulating objects to be browsed by a portable terminal in another terminal in advance and then browsing the portable terminal side later, AvantGo (http: // ww
w.muchy.com/review/avantgo.html). In addition, as a conventional technology relating to the use of a search engine on the Internet by a portable terminal, Japanese Patent Application Laid-Open No. 2000-298632 and “Google in i-mode!” (Http://www.google.co.jp)
m / intl / ja / imode.html) and the like are known.

[0008]

By the way, in order to convert a web document so that a user can quickly reach a desired portion, a user can select a desired portion (area) of the web document. ) Is registered in advance (this specification may be made on a terminal with a large screen such as a PC). When browsing the web document on a mobile terminal when going out, only the data of the registered part is read It is very effective to cut out and convert it to be displayed on a mobile terminal. Further, when registering the cutout target area, if a web document including the data to be cutout is displayed on a terminal having a large screen size such as a PC and the area can be visually selected on the display screen, it is very difficult for the user. The region to be clipped can be registered with an intuitive and easy-to-understand operation.

However, in the above-mentioned conventional structured document conversion system, it is impossible to visually select and register a cutout target area on a screen, and to convert a web document based on the registered cutout target area. There is a first problem.

In order to convert a structured document so that a user can easily reach a desired portion, a portable terminal such as a PC having a large screen size and being constantly connected to a communication network is required. By registering in advance the designation of the browsing target, the place you want to see in it, and the timing of obtaining the browsing target document, you can obtain, store, and convert the original browsing target document from the document source. However, when a user actually browses a structured document using a mobile terminal, it becomes possible to browse a document that has already been converted into a format suitable for the mobile terminal, which is extremely low in terms of waiting time. It is valid.

[0011] Even when the original document source becomes inaccessible due to some kind of communication failure or the like, it becomes possible to present at least the previously stored information to the portable terminal side. Furthermore, in a plurality of structured document groups, a place to be browsed is registered, and information extracted from each document is integrated, and a new structured document is generated, so that a user can access various places. It is possible to collectively access the desired information scattered by the user, and the user can quickly acquire only necessary information.

However, in the above-mentioned conventional structured document conversion system, a user registers in advance a document to be viewed and a place to be viewed in the document, and stores, converts, and integrates the document in a prescribed place to execute the portable terminal. There is a second problem that it is not possible to present a document that has been converted into a document that can be already viewed when browsing from a Web site. Further, the above AvantG
In o, the browsing target by the mobile terminal can be stored in another terminal in advance, and can be browsed later on the mobile terminal side, but a structured document conversion unit corresponding to a dynamic access request is provided. Therefore, information other than the information initially stored in the terminal cannot be browsed on the mobile terminal, or the user himself / herself cannot set the necessary information in each of a plurality of structured documents and integrate and display them. .

[0013] In addition, when browsing a web document on a portable terminal and accessing information that cannot be displayed on the portable terminal, the browsing operation of the user is not hindered. In order to enable access, when accessing information with a data format that requires a specific application, the mobile terminal will not be able to browse the target information, and instead will store the target information The normal browsing operation can be continued by indicating the location, and the target information is stored in a specified location. The user can continue browsing operation to another web document or the like on the portable terminal, and quickly acquire and browse the information stored on a terminal such as a PC that can view the information stored and processed later.

However, in the conventional structured document conversion system, information having an information amount and a data format which cannot be displayed on a portable terminal (information having a special data format which does not correspond to the conversion processing of the system, etc.). There is a third problem that the original information cannot be stored in a prescribed location when accessing the.

Further, when using a search engine used on a normal Internet when browsing with a portable terminal, the search result is limited to an appropriate amount of information, and the user wants to see the search result destination page. In order to convert the part so that it can be reached quickly, the user registers in advance the elements (title, Internet address, etc.) that the user wants to see in the search results of the web document, and uses the mobile terminal when going out When using a search engine, by extracting only the registered part of the data and displaying it on the mobile terminal, the searchability of the search results is improved, and when accessing the search result destination page The user can easily find the information required by specifying the location of the page where the word used in the search or by directly indicating the location where the search word is located. Can reach, it is very effective.

However, in the above-mentioned conventional structured document conversion system, the user himself / herself can set an element desired to be browsed on the portable terminal in the search result, or designate one or a plurality of arbitrary pages desired to be browsed from the search result list at the same time. There is a fourth problem that it is not possible to provide a means that enables the search or to perform a document conversion such as directly extracting or integrating a plurality of locations by specifying the location of the search phrase in the page of the search result.

The present invention has been made in view of the above points,
A first object of the present invention is to provide an environment in which a part desired by a user is registered in advance, a part registered at the time of browsing by a portable terminal is extracted, and a structured document in a format that can be browsed by a portable terminal is generated. It is an object of the present invention to provide a structured document conversion system and a structured document conversion program which can convert a web document so that a user can quickly reach a desired portion in a web document.

A second object of the present invention is to register in advance a group of structured documents desired by a user and the timing of obtaining them, and obtain a group of documents designated in advance from a structured document source. , Storage, conversion, and integration environment to reduce waiting time when browsing from mobile devices,
It is an object of the present invention to provide a structured document conversion system and a structured document conversion program capable of collectively accessing information desired by a user.

A third object of the present invention is to provide an environment in which, when accessing information having an information amount or data format that cannot be displayed on a portable terminal, the original information can be stored in a prescribed location. Therefore, when accessing information that cannot be displayed on a mobile terminal, a structured document conversion system and a structured document that can quickly access information that could not be browsed from another terminal later without hindering a user's browsing operation To provide a conversion program.

Further, a fourth object of the present invention is to register a part desired by the user in the search result in advance, extract the part registered at the time of browsing with the portable terminal, and browse the portable terminal. By providing an environment that generates a structured document in a format that can specify any search result and an environment that specifies the location of the words used in the search in the structured document of the search result, the amount of information that matches the search result Another object of the present invention is to provide a structured document conversion system and a structured document conversion program which can convert a search result destination page so that a user can quickly reach a desired portion.

[0021]

In order to achieve the first object, the present invention obtains a structured document represented by a web document by a document obtaining means, and obtains the structured document by a document analyzing means. Analyzes the hierarchical structure and screen display layout of the object, and based on the display of the analysis result, when the user specifies and inputs a part (object) containing the information to be viewed from the input means, the object is detected from the structured document. Specified object information can be registered in advance. Then, when the user requests browsing of the structured document from the portable terminal, the structured document is analyzed in exactly the same manner as in the registration, and the analysis result is registered by the object specifying means and registered in the object registration means. A required part is specified from the requested structured document based on the information of the object and the generated object is generated as a structured document in a format that can be browsed by the mobile terminal by the document generation means, and the portable object is generated. It is configured to display on a terminal.

According to the present invention, when a structured document is browsed by a portable terminal, a user can quickly reach an object desired to be viewed in the structured document, thereby achieving the first object. it can. However, the content of the structured document requested to be displayed by the mobile terminal is not always exactly the same as the content of the structured document when the designated input area is set (for example, if the document is a web document, May have been updated). Accordingly, the analysis result of the structured document when the designated and input area is registered is compared with the analysis result of the structured document at the time of the display request, and the designated and input object portion is specified.

According to the present invention, in order to achieve the above second object, a structured document (for example, a URL of a web document) or the like, which allows a user to traverse and acquire a document source in advance by a document source traversing designation unit, The user specifies the timing of patrol (for example, when patrols are performed on a regular basis every day or when a specified structured document is accessed, etc.), and registers this in the document source patrol registration means. Objects specified by the user can be specified and extracted from the structured documents acquired according to the timing registered in the patrol registration means, and the objects extracted from each of the structured documents acquired and visited at the same timing can be viewed on the mobile terminal. After the document is converted into a simple document, the document is integrated by the object integrating means, and when there is an access request from the portable terminal, this is presented. According to the present invention, the objects extracted from each of the structured documents requested to be browsed from the portable terminal can be presented collectively, so that the second object can be achieved.

In order to achieve the third object, the present invention comprises a stored document registering unit, a document discriminating unit, and a document storing unit, and the amount of information to be browsed accessed by a user from a portable terminal. Check whether the data can be displayed on the mobile terminal that is to be viewed from the data format, and for documents that cannot be displayed on the mobile terminal, store the document in the location registered by the user in advance and perform document storage processing. At the same time, when there is a browsing target having a data format or the like registered in the stored document registration unit before the document generation unit can follow the link from the document in the structured document, the acquired structured document is When generating a structured document in a format that can be browsed on a mobile terminal, it has been made clear that the target to be browsed on the mobile terminal cannot be viewed on a mobile terminal and can be stored in a specified location. It is.

That is, in the present invention, the portable terminal side includes:
By displaying that the information accessed by the user cannot be displayed on the mobile terminal, or by displaying information that can be displayed by conversion processing such as reducing the size of a large screen image, the user can continue browsing operation without waiting time it can. Furthermore, by notifying the portable terminal of information regarding the storage process by e-mail or the like when the document storage process is completed, the user can be notified of the completion of the storage process and the information such as the storage location and name of the information. Obtainable.

Further, in order to achieve the fourth object, the present invention uses a structured document having a search processing function from a portable terminal to obtain a structured document in which a list of search results is displayed, and perform a search. When browsing to an arbitrary structured document is requested from the results, the document analysis unit searches the search term recorded in the search term recording unit in the result of analyzing the structured document structure, and searches the search term. A search term search means for extracting an object including the search term, wherein the document generation means specifies a location in the search term when the search term search means generates the extracted object as a structured document in a format that can be browsed by a mobile terminal. It is characterized by. Also, if you request to browse multiple structured documents from the search results at once,
The document analysis means and the phrase search means extract an object including a search phrase from each of the plurality of search results, and integrate the objects by the object integration means. Further, according to the present invention, the document generating means includes an index document generating means for displaying a list of browsing requests for the plurality of extracted objects.

That is, according to the present invention, when an access request to any of the search results is made from the portable terminal, the structured document at the access destination is converted into a document that can be browsed on the portable terminal, and the user can use the structured document. Based on the terms used to search,
By providing an environment in which the position of a search term in the target structured document is specified, the search result can be limited to an appropriate amount of information, and the user can quickly reach an object that the user wants to see on the search result destination page.

[0028]

Next, embodiments of the present invention will be described in detail with reference to the drawings.

(1) First Embodiment First, a first embodiment of the present invention will be described. The most important point of the first embodiment is that a document structure analyzing unit is provided. This document structure analysis means analyzes the hierarchical structure of the structured document to be converted. When the user uses the input unit to specify a portion including the information he / she wants to view for the structured document to be converted, the specified information is registered.

FIGS. 1 and 2 show the configuration of a structured document conversion system and a structured document conversion program according to a first embodiment of the present invention. FIG. 1 is a configuration diagram for designating a portion of a structured document to be browsed when the user wants to browse on a mobile terminal, and FIG. FIG. 3 is a configuration diagram for extracting a designated portion from a structured document when browsing a document, and the same components are denoted by the same reference numerals in both drawings.

FIG. 1 shows a communication means 100, a document acquisition means 101, a document display means 102, a document analysis means 103, an object designation function, in which an information processing device (computer) as a terminal 10 functions by a structured document conversion program. A means 104, an object registration means 105, a display means 106 and an input means 107 are shown. FIG. 2 shows a communication means 10 in which an information processing device (computer) serving as a terminal 10 functions according to a structured document conversion program.
0, a document acquisition unit 101, a document analysis unit 103, an object registration unit 105, an object identification unit 108, and a document generation unit 109.

In both figures, the structured document to be viewed is:
It is stored in the document source 11. The document source 11 is, for example, a web document server. In this case, the structured document to be browsed is a web document. Terminal 10 (for example, P
C) acquires the document stored in the document source 11 via the communication network 12 (for example, the Internet).

In FIG. 1, the user operates the input unit 107.
The user instructs the document acquisition unit 101 to acquire a structured document that the user wants to view from the portable terminal by using a keyboard and a mouse (for example, when going out) (for example, the UR of a web document).
L), the document obtaining unit 101 sets the communication unit 1
The designated document is acquired from the document source 11 via the communication network 12 and the communication network 12, and the document display unit 102 (for example, a web browser) displays the acquired structured document on the display unit 106 (for example, a liquid crystal display).

The document analysis means 103 includes the document display means 10
2 analyzes the element (object) of the structured document displayed on the current screen and displays the analysis result
To be displayed. The document analysis means 103 includes a document structure analysis means 1030. The document structure analysis unit 1030 analyzes the structured document and detects the hierarchical structure of the object of the structured document.

For example, as a result of displaying the structured document by the document display means 102 and analyzing by the document structure analysis means 1030,
Assume that an object of a structured document is detected. 3 shows a structured document obtained by the document acquisition unit 101, FIG. 4 shows a display layout of objects of the structured document, and FIG. 5 shows a result analyzed by the document structure analysis unit 1030.

Tags <x1>... </ X1>, <
x2>... </ x2> and objects X1 and X2 in FIG. 4 and objects X1 and X2 in FIG.
Correspond to each other, and the corresponding relations of the other objects are also the same. The document analysis means 103 displays on the display means 106 an analysis result screen in which objects are arranged according to the result of the document structure analysis by the document structure analysis means 1030.

The display means 10 is provided by the document analysis means 103.
When the user looks at the structured document analysis result screen displayed in 6, the user uses the input unit 107 to include information that the user wants to browse from the portable terminal when going out or the like in the structured document. When a part (object) is visually specified, the object specifying means 104 detects which object is specified, and notifies the object registration that the specified object is specified for the currently displayed structured document. Register in the means 105.

For example, in the examples of FIGS. 3, 4 and 5, it is assumed that the object Y1 is visually specified on the analysis result screen displayed on the display means 106 as shown in FIG. In this case, the object designating unit 104 sets the objects (Y11, Y12, Y
13) is detected, and is registered in the object registration unit 105 together with the ID of the currently displayed structured document. It is assumed that this ID is Z. For example, if the target structured document is a web document, its ID is
L, in the case of an output from some arithmetic means such as a search result by a search process, there is an arithmetic means to be used.

The object can be specified by:
In addition, designation by the hierarchy and the order of the objects can be considered. For example, as shown in FIG.
It is assumed that an object having the same hierarchy and the same rank is specified.
In this case, the object designating means 104 detects that the object Y11 has been designated, and the document structure analyzing means 1
Based on the hierarchical structure obtained from 030, the user designates an object having the same hierarchy and the same rank as the object Y11 (in this case, the first element Y21, Y31,..., Y91, which is the first element of the third hierarchy). And object registration means 1
Register at 05.

Assume that the user attempts to browse the structured document with ID = Z using the portable terminal 13 when going out (FIG. 2). This request is sent to the terminal 1 via the communication network 12.
0 is transmitted to the document acquisition unit 101. The document acquisition unit 101 acquires the structured document of the requested ID = Z from the document source 11 via the communication network 12 and the communication unit 100. The document analysis unit 103 includes the document acquisition unit 10
1 analyzes the structured document of ID = Z acquired and detects the hierarchical structure of the object. Object specifying means 1
08 specifies an object including information to be displayed on the mobile terminal 13 from the object analysis result by the document analysis unit 103 and the information registered in the object registration unit 105.

For example, as shown in FIG.
When 1 or less is specified, the object specifying unit 108 specifies an object group corresponding to the object Y1 or less from the acquired structured document, and sets this object group as a display target object. However,
Information described in the display object group is
It may be different at the time of registration at the terminal 10 and at the time of requesting browsing from the mobile terminal 13.

Even when the hierarchical structure of the objects in the document is different between the time of registration at the terminal 10 and the time of request for browsing from the portable terminal 13, the object Y1 and below are uniquely specified in the document. If the possible information is extracted by the document analysis unit 103 and the information is registered in the object registration unit 105, even if the document has been changed, it is possible to specify the object Y1 and below.

The document generating means 109 in FIG. 2 converts the structured document including the information in the object into the portable terminal 13 so that the information in the object specified by the object specifying means 108 can be viewed on the portable terminal 13. Generate in a format that can be displayed in. The structured document generated by the document generation unit 109 is displayed on the mobile terminal 13 by the communication unit 100 via the communication network 12, and as a result, the user of the mobile terminal 13 can use the ID currently stored in the document source 11. = Without viewing all of the structured documents in Z
Only the information of the part specified by the terminal 10 can be browsed immediately.

Therefore, by using the structured document conversion system according to the first embodiment, when browsing a document from the portable terminal 13, a great deal of labor conventionally required for searching for a portion to be browsed is unnecessary. In addition, since the data amount of the document transmitted to the mobile terminal 13 is minimized, the communication fee can be reduced.

The example described above is an example in which the document source 11 exists outside the terminal 10 and can be obtained via the communication network 12.
The same applies to the case where it exists inside 0. In this case, FIG.
9, the document source 11 is connected to the document acquisition unit 101.

As shown in FIG. 10, another terminal 14 connected to the communication network 12
03, an object registration unit 105 and an object identification unit 108, and in a case where the structured document of the document source 11 is acquired by the terminal 10 after passing through the terminal 14, the document acquiring unit 101 acquires the structured document by the terminal 10. The document to be used is only information including the object registered by the user in advance, and the communication fee can be further reduced.

(2) Second Embodiment Next, a second embodiment of the present invention will be described. The most important point of the second embodiment is that a screen analyzing means is provided. The structured document to be converted is displayed on the screen, and the layout information (such as the hierarchical structure and the coordinate values) of the displayed structured document is analyzed by the screen analysis unit. When the user uses the input unit to specify a portion including the information that he / she wants to visually see on the screen on which the structured document to be converted is displayed, the specified information is registered.

FIGS. 11 and 12 are block diagrams of a structured document conversion system and a structured document conversion program according to a second embodiment of the present invention. FIG. 11 is a configuration diagram for designating a part of the structured document to be browsed when the user browses with a portable terminal, and FIG. FIG. 3 is a configuration diagram for extracting a designated portion from a structured document when browsing a document, and the same components are denoted by the same reference numerals in both drawings.

FIG. 11 shows an information processing apparatus (computer) which is a terminal 10 according to a structured document conversion program.
1 shows a communication unit 100, a document acquisition unit 101, a document display unit 102, a document analysis unit 103, an object designation unit 104, an object registration unit 105, a display unit 106, and an input unit 107, which function. FIG.
Reference numeral 2 denotes a communication unit 1 in which an information processing device (computer) as the terminal 10 functions according to a structured document conversion program
00, document acquisition means 101, document analysis means 103, object registration means 105, object identification means 108
And the document generation means 109.

As shown in FIGS. 11 and 12, the second embodiment differs from the first embodiment in that the document analyzing means 103 has a document structure analyzing means 1030 instead of the document analyzing means 103. The difference is that the configuration includes a screen analysis unit 2030. Hereinafter, components different from those of the first embodiment will be mainly described.

In FIG. 11, the document analyzing means 103
The element (object) of the structured document displayed on the current screen is analyzed by the document display means 102, and the analysis result is displayed on the display means 106. A screen analysis unit 2030 in the document analysis unit 103 analyzes the elements (objects) of the structured document displayed on the current screen by the document display unit 102, and detects the hierarchical structure and the coordinate values of the object of the structured document. I do.

For example, the document display means 102 displays the structured document on the display means 106, and displays the display on the screen analysis means 1.
It is assumed that the object of the structured document is detected as shown in FIGS. 13 and 14 as a result of the analysis performed by the screen analysis unit 2030 in 03. FIG. 13 shows the display layout of the objects of the structured document, and FIG. 14 shows the hierarchical structure of each object in FIG. Objects X20 and X21 in FIG. 13 and objects X20 and X21 in FIG.
And the corresponding relations of the other objects are the same.

The screen analysis means 20 for analyzing the display of the structured document by the document display means 102 and detecting the layout and the hierarchical structure of the objects as shown in FIGS.
30 can be realized using, for example, an off-screen model generation technique. The off-screen model generation technology is a technology that has been developed to enable a visually impaired person to use a PC. For example, reference 1 (BYTE, 1991)
December (December), pages 118-128, and information processing (Information Processing Society of Japan), 1995, Vol. 36, No. 12, pages 1133-1139). In addition, a system having a function of analyzing a display screen of a graphical user interface (GUI) of a PC using an off-screen model generation technology is disclosed in Reference 2 (information processing society research report, 97-HI-
73 (July 11, 12 1997, pp. 7-12).

At the terminal 10, the user looks at the screen of the structured document displayed on the display means 106 by the document display means 102, and when the user goes out of the structured document by using the input means 107, When a portion (object) containing information desired to be browsed from the portable terminal is visually specified, the object specifying unit 104 detects which object is specified, and determines whether the structured document is being displayed. That the object was specified
Register in the object registration means 105.

For example, in the examples of FIGS. 13 and 14,
It is assumed that the object X2213 in FIG. 13 is visually specified on the screen displayed on the display unit 106 (for example, as in FIG. 15). In this case, the object specifying means 1
04 detects that the object X2213 has been designated, and registers it in the object registration means 105 together with the ID of the currently displayed structured document. It is assumed that this ID is Z.

Next, when the user goes out, for example,
The operation when browsing the structured document of ID = Z using the No. 3 will be described with reference to FIG. This request is sent to the communication network 12 shown in FIG.
00, the document acquisition means 101 in the terminal 10
Conveyed to. Then, the document acquiring unit 101 acquires the structured document of the requested ID = Z from the document source 11 via the communication unit 100 and the communication network 12.

The document display means 102 is provided by the document acquisition means 10
The display process of the structured document of ID = Z acquired by step 1 is executed, whereby the screen analysis unit 2030 analyzes the display of the structured document of ID = Z and detects the hierarchical structure and coordinate values of the object. The object specifying unit 108 specifies an object including information to be displayed on the mobile terminal 13 from the result of the object analysis by the screen analyzing unit 2030 and the information registered in the object registering unit 105.

Here, as shown in the example of FIG.
, The object specifying means 108 in FIG. 12 selects, from the acquired structured document of ID = Z,
An object corresponding to the object X2213 is specified, and this object is set as a display target object.
However, the information described in the object X2213 may be different at the time of registration at the terminal 10 and at the time of requesting browsing from the mobile terminal 13.

Further, even when the layout and the hierarchical structure of the objects in the document are different at the time of registration at the terminal 10 and the time of browsing request from the portable terminal 13, the object X2213 is uniquely stored in the document. By extracting the identifiable information by the screen analysis unit 2030 and registering the information in the object registration unit 105,
Even if the document has been changed, object X2213
Can be specified.

The document generating means 109 in FIG. 12 converts the structured document including the information in the object into the portable terminal 13 so that the information in the object specified by the object specifying means 108 can be browsed on the portable terminal 13. Generate in a format that can be displayed in. The structured document generated by the document generation unit 109 is displayed on the display unit of the mobile terminal 13 via the communication unit 100 and the communication network 12.

Therefore, by using the structured document conversion system according to the second embodiment, similar to the first embodiment, when browsing a document from the portable terminal 13, it is possible to search for a portion to be browsed. A great deal of labor conventionally required becomes unnecessary, and the data amount of the document transmitted to the portable terminal 13 is minimized, so that the communication cost can be reduced. Furthermore, when registering a part to be viewed on the mobile terminal 13, the display layout of the object is analyzed, and the object can be specified by a more visual and easy operation by directly specifying the object on the display screen by the display unit 106. Becomes

The example described above is an example in which the document source 11 exists outside the terminal 10 and can be obtained via the communication network 12.
The same applies to the case where it exists inside 0. In this case, FIG.
As shown in FIG. 6, the document structure analyzing unit 1030 of FIG.
Is connected to the document acquisition unit 101.

As shown in FIG. 17, another terminal 14 connected to the communication network 12

3. In the case where the terminal 10 includes the object registration unit 105 and the object identification unit 108 and acquires the structured document of the document source 11 after passing through the terminal 14, the document acquisition unit 101 acquires the structured document. The document to be used is only information including the object registered by the user in advance, and the communication fee can be further reduced.

The example described above is based on the document analysis unit 1.
03 is an example provided with the screen analysis means 2030, but also has the document structure analysis means 1030 described in the first embodiment, so that the document structure analysis means 1 shown in FIG.
When an object is selected on the analysis result display screen according to 030, the visual operability and the flexibility of object designation are improved by, for example, specifying the corresponding object on the screen displayed by the document display means 102 by enclosing the object with a rectangular frame. It is desired to improve the certainty of specifying the specified object by the object specifying unit 108.

(3) Third Embodiment Next, a third embodiment of the present invention will be described. The most important point of the third embodiment is that a document source patrol registration unit is provided. The document source patrol registration means specifies a structured document (for example, a URL of a web document) to be traversed and acquired from a document source, and a timing for acquiring a document source (for example, a case where the document source is to be circulated every day at a fixed time or to a prescribed structured document). The document acquisition unit acquires a structured document according to the output of the document source patrol registration unit.

FIGS. 18 and 19 are block diagrams of a structured document conversion system and a structured document conversion program according to a third embodiment of the present invention. FIG. 18 is a configuration diagram for performing a cyclic setting such as a specification of a structured document to be stored in the terminal 10 (for example, a PC) in advance and a timing of acquiring a target structured document from a document source. In accordance with the patrol setting set by the user, the specified document is acquired from the document source, the part (object) specified by the user in advance is specified and extracted, and each object can be viewed on the mobile terminal. Is a configuration diagram for generating and accumulating a new structured document by integrating them into a new structured document. In both figures, the same components are denoted by the same reference numerals.

FIG. 18 shows an information processing apparatus (computer) which is the terminal 10 according to the structured document conversion program.

Is shown. FIG. 19 illustrates a communication unit 100 and a document acquisition unit 10 in which an information processing device (computer) serving as the terminal 10 functions according to a structured document conversion program.
1. Document analysis means 103, object registration means 10
5. Object specifying means 108, document generating means 109
And a document circulation registration unit 300, and further includes a document recording unit 301.

As shown in FIGS. 18 and 19, in the third embodiment, a document source patrol registration unit 300 is further added to the terminal 10 in the first embodiment and the second embodiment. The object specifying unit 104 includes a document source patrol specifying unit 3040, and the document generating unit 109 includes an object integrating unit 3090 and an index document generating unit 3091. Hereinafter, components different from those of the first and second embodiments will be mainly described.

In FIG. 18, the user enters the input means 107
When the document acquisition unit 101 is instructed to acquire a structured document that the user wants to view from the portable terminal when going out, the document acquisition unit 101 transmits the designated document to the document source via the communication unit 100 and the communication network 12. 11 and the document display unit 102 causes the display unit 106 to display the document acquired by the document acquisition unit 101.

The document analysis means 103 is provided with the document display means 10
2 analyzes the hierarchical structure and the coordinate values of the elements (objects) of the structured document displayed on the current screen, and causes the display means 106 to display the analysis result. Document analysis means 103
The user looks at the structured document analysis result screen displayed on the display means 106 by the user, and uses the input means 107 to input information that the user wants to browse from the portable terminal in the structured document when going out. When the part (object) containing is visually specified, the object specifying means 104
It detects which object has been designated, and registers in the object registration means 105 that the object has been designated for the currently displayed structured document.
Note that the document analysis unit 103 includes one or both of the document structure analysis unit 1030 in the first embodiment and the screen analysis unit 2030 in the second embodiment.

Subsequently, when the user uses the input means 107 to specify the timing of acquiring the structured document from the document source 11 (eg, at regular time intervals or when there is a request to access a prescribed document), The document source patrol specifying unit 3040 included in the object specifying unit 104 registers the patrol timing and the structured document to be acquired at the time of patrol in the document source patrol registration unit 300.

Next, a part (object) that the user wants to view, which is designated in advance, is specified and extracted, and each object is converted into a document that can be viewed on the portable terminal 13, and then integrated to form a new structured document. The operation of generating and accumulating is described with reference to FIG. Document acquisition means 101
Obtains a document group from the document source 11 via the communication unit 100 and the communication network 12 according to the patrol setting registered in the document source patrol registration unit 300 by the user in advance, as described with reference to FIG.

In FIG. 19, the document analysis means 103
The element (object) of the structured document acquired by the document acquiring unit 101 is analyzed, and the hierarchical structure of the object is detected. The object specifying means 108 is a function of the document analyzing means 10.
3 from the result of the object analysis by the object registration unit 3 and the information of the object to be displayed registered in the object registration unit 105,
Extract.

The document generating means 109 can display a structured document including the information in the object on the mobile terminal 13 so that the information in the object specified by the object specifying means 108 can be viewed on the mobile terminal 13. Object integration means 30
At 90, the plurality of structured documents are integrated into one structured document. The index document generation unit 3091 in the document generation unit 109 generates a structured document in which a list of access requests (such as links) to a plurality of structured documents is displayed.

For example, in the example of FIG. 20, each document (document 3101, document 3102,..., Document 3) of the structured document group 3100 acquired according to the tour setting specified by the user.
109), the display target objects designated by the user in advance are X31, X32,.
X39. The document analysis unit 103, the object registration unit 105, and the object identification unit 108 extract each object. The document generation unit 109 generates, for each extracted object, a document 3201, a document 3202,.
09 is generated.

Structured document 310 of structured document group 3100
1 corresponds to the object X31 in the structured document 3201 of the structured document group 3200, and the corresponding relationship of the other objects is the same. The object integrating means 3090 integrates the document group (object group) in the structured document group 3200 and generates one structured document 3300 having all the extracted objects (X31, X32,..., X39). In the example of FIG. 20, the link 330 described before each object
By selecting 1, access to the original structured document having each object can be requested.

Further, the index document generation means 3091 provides a link for requesting access to a document group in the structured document group 3200 and a head part (object) of the linked structured document.
Is generated as a structured document 3400. For example, by selecting the link 3401 in the structured document 3400, it is possible to request access to the structured document 3201.

Referring back to FIG. 19, the document recording unit 301 stores the portable terminal 1 generated by the document generation unit 109.
In step 3, a structured document that can be browsed is stored. For example, when the user attempts to browse the structured document for which the patrol setting has been performed using the portable terminal 13 when going out, the communication network 12
, The structured document to be browsed stored in the document recording unit 301 is acquired and displayed on the display unit of the mobile terminal 13. As a result, the user of the mobile terminal 13 can use the terminal 1 in advance.
Only the desired information of the document group registered at 0
You can get it quickly just by accessing.

Therefore, by using the structured document conversion system according to the third embodiment, the terminal 1 such as a PC can be used.
0, the group of documents to be browsed is registered in the document recording unit 301 in advance, and the original group of documents to be browsed is acquired from the document source 11;
By performing storage, conversion, and integration processing, when a user actually browses a desired structured document using the mobile terminal 13, a group of documents that have already been converted into a format suitable for the mobile terminal 13 are read. The integrated document can be browsed, so that the communication time in the portable terminal 13 can be reduced and desired information can be collectively accessed. In addition, even when the original document source 11 cannot be accessed due to some kind of communication failure or the like, since the browsing target document group is registered in the document recording unit 301, at least the previously accumulated information is stored in the portable terminal 13. It can be presented.

The example described above is an example in the case where the document source 11 exists outside the terminal 10 and can be obtained via the communication network 12.
The same applies to the case where it exists inside 0. In this case, FIG.
As shown in FIG. 1 and FIG.
Connected to.

As shown in FIG. 23, another terminal 14 connected to the communication network 12
02, document analysis means 103, object registration means 10
5. In the case where the terminal 10 includes the object identification unit 108, the communication unit 110, and the document acquisition unit 141, and the terminal 10 acquires the structured document of the document source 11 via the terminal 14, the terminal 10 acquires the document. The document acquired by the means 101 is only information including the object registered by the user in advance, and the communication fee can be further reduced.

(4) Fourth Embodiment Next, a fourth embodiment of the present invention will be described. The most important point of the fourth embodiment is that it includes a document discriminating unit and a document storing unit. The user can access the mobile terminal according to the information amount and data format of the viewing target accessed from the mobile terminal. The document discriminating means confirms whether or not the document can be displayed, and for a document which cannot be displayed on the portable terminal, stores the document in a location of the document storing means registered in advance by the user.

FIG. 24 is a block diagram of a structured document conversion system and a structured document conversion program according to a fourth embodiment of the present invention. In the present embodiment, the data format and the amount of information of a document to be stored (a file exceeding a certain upper limit is to be stored, etc.) and a storage location of the storage target are registered in advance, and the user stores the data on the mobile terminal. When accessing a document registered as a target, the document is stored in the specified location, and the information accessed by the user cannot be displayed on the mobile terminal on the mobile terminal side, or
This is a configuration for displaying information that can be displayed by a conversion process such as reducing a large screen image.

FIG. 24 shows an information processing apparatus (computer) which is the terminal 10 according to the structured document conversion program.
Function, the communication means 100, the document acquisition means 101, the input means 107, the document generation means 109, the document discrimination means 40
0, a document storage unit 401 and a stored document registration unit 402, and a document recording unit 301.

In FIG. 24, a document to be browsed and stored according to the present embodiment is stored in the document source 11.
The document source 11 is, for example, a web document or a pdf format (Adobe
Is a server that has specific application data, such as Adobe Acrobat files. In this case,
The structured document to be browsed is a web document, and the document to be stored is application data. Terminal 10
Acquires the document stored in the document source 11 via the communication network 12 and the communication means 100.

First, the user operates the input unit 107 to
Information that cannot be displayed on the mobile terminal 13 while browsing a web document from the mobile terminal 13 such as when going out (application /
When the user accesses the data (data), the location of the document recording unit 301 (designated by a folder path, URL, or the like) that stores the target information is registered in the stored document registration unit 402. In addition,
In addition to the location of the document recording unit 301, it is also possible to register the setting of whether or not to perform the accumulation process for each data format and information amount in the accumulated document registration unit 402.

Thereafter, it is assumed that the user attempts to browse the structured document of the document source 11 using the portable terminal 13 when going out, for example. This request is sent to the communication network 12, the communication means 10
0 is transmitted to the document discriminating means 400, and the document discriminating means 400 stores the requested structured document in the storage object (mobile terminal 13) registered in the stored document registering means 402.
It is determined whether or not the information is information that cannot be browsed.

If the structured document requested by the user is not to be stored, the request is transmitted to the document obtaining means 101, and the document obtaining means 101 converts the requested structured document into
It is obtained from the document source 11 via the communication means 100 and the communication network 12. The document generation unit 109 converts the structured document acquired by the document acquisition unit 101 into the portable terminal 13.
Is generated in a format that can be displayed on the mobile terminal 13 so that the user can browse the data. At this time, if a document or information to be stored exists in the acquired structured document and an access means such as a link to the document or information to be stored is provided, the access destination is described in the target access means notation. Is the mobile terminal 13
Indicates that the information is information of an information amount or format that cannot be displayed (information to be stored).

For example, in the example of FIG. 25, the access destination is a link 41 which is information that cannot be browsed by the portable terminal 13.
01, the document generation unit 109 determines that the access destination of the link 4101 is the mobile terminal 13
In order to clearly indicate that browsing is not possible, link 41
A structured document 4200 in which “[download]” is additionally described in 01 is generated.

The user indicates that the access destination of the link 4101 cannot be browsed on the portable terminal 13 and selects the link 4101 from the information described in the postscript, so that the information of the access destination is stored in the document recording unit 301. We can understand that we can accumulate. Also, a link 41 that is information that cannot be browsed by the mobile terminal 13 such as the structured document 4100
01, there is a check box 4202 corresponding to each link 4201, and a check box 4202
It is also conceivable that the structured document 4200 is provided with a button 4203 for collectively accumulating the objects selected by the user. A link 4204 to a structured document having a function for confirming or changing the location of the document recording unit 301
May be provided in the structured document 4200.

Next, if the structured document requested by the user is to be stored, the document discriminating means 4 shown in FIG.
00 outputs the requested document and the location of the document recording unit 301 registered in the stored document registration unit 402 to the document storage unit 401. The document storage unit 401 obtains the requested document from the document source 11 via the communication network 12, and then stores the document in the document recording unit 301.

Since the processing operation of the document storage means 401 is performed independently of the other processing units, the document storage means 40
The user can browse the structured document using the mobile terminal 13 via the terminal 10 even while the storage device 1 is performing the storage process on some document. The document storage unit 401 sends, by e-mail or the like, information indicating that the storage processing to the document recording unit 301 has been completed and the name and location of the document on which the storage processing has been performed, by the communication unit 100 and the communication network 12. Is notified to the mobile terminal 13 via the.

Therefore, according to the structured document conversion system in the fourth embodiment, when the structured document is browsed from the portable terminal 13, information that can be traced from the structured document being browsed is not browsed. And the storage target (information that cannot be browsed by the mobile terminal 13) can be presented to the user. As a result, it is possible to determine whether or not the user accumulates information that cannot be browsed by the mobile terminal 13. Depending on the content, information that is not enough for the user to accumulate and see from the trace is not subjected to the accumulation process, and the content is not later processed Only the storage target information that the user wants to view can be stored in the document recording unit 301.

Further, in this embodiment, by accessing the document to be stored, the document to be stored is stored in the storage location of the document recording unit 301 which has been set in advance, and another terminal is used later. It is possible to quickly reach the target information. It is also possible to view that the document storage processing, which was originally performed by directly operating the terminal 10 such as a PC at home or the like, can be remotely controlled using the portable terminal 13 when going out.

The above-described example is based on the case where the document source 11 exists outside the terminal 10, can be acquired via the communication network 12, and the document recording unit 301 exists inside the terminal 10. However, as shown in FIG. 26, the document recording unit 301 may be provided outside the terminal 10 and acquired via the communication network 12,
Further, as shown in FIG.
0, and the document source 11 may exist inside the terminal 10. In this case, as shown in FIGS. 26 and 27, the document recording unit 301 is connected to the communication network 12, and the document source 11 is connected to the document determination unit 400.

(5) Fifth Embodiment Next, a fifth embodiment of the present invention will be described. The most important point of the fifth embodiment is that a search term recording unit and a search term search unit are provided. When a user browses a search result using a computing unit having a search function from a portable terminal. Then, a display target object registered by the user in advance is extracted from the structured document having the search result information, and displayed on the portable terminal. Further, when there is a request for access to any of the search results from the mobile terminal, the position of the word used for the search in the structured document of the access destination is searched and specified by the search word search means.

FIGS. 28 and 29 show a structural diagram of a structured document conversion system and a structured document conversion program according to a fifth embodiment of the present invention. FIG. 28 shows that when the user browses the structured document on the search result display screen using the mobile terminal 13, a part designated in advance is extracted from the structured document, and the mobile terminal 13 is displayed on the search term input screen. 1
3 is a configuration diagram for recording a search phrase input by a user from No. 3; FIG.

FIG. 29 shows a case where the user selects and requests an arbitrary result (structured document) from the browsing result presented on the portable terminal 13 and converts the structured document of the requested retrieval result into a portable terminal. 13 to limit the amount of information to allow browsing, and to generate an index page to specify where in the structured document the words used in the search are located, When a result (structured document) is selected and requested, an object including a search term is extracted from each of the plurality of search results requested, and each object is converted into a document that can be viewed on the mobile terminal 13 and then integrated. FIG. 2 is a configuration diagram for generating and accumulating a new structured document. 28 and 29, the same components are denoted by the same reference numerals.

FIG. 28 shows an information processing apparatus (computer) which is the terminal 10 according to the structured document conversion program.
1 shows a communication unit 100, a document acquisition unit 101, a document analysis unit 103, an object registration unit 105, an object identification unit 108, and a document generation unit 109, and a configuration having a search phrase recording unit 500. FIG. 29 shows the terminal 1 by the structured document conversion program.
0, the information processing device (computer) functions, the communication unit 100, the document acquisition unit 101, and the document analysis unit 10
3, a document generation unit 109 and a search phrase search unit 501; and a search phrase recording unit 500.

In the fifth embodiment, first, using the configuration described in the first embodiment, the user
0, the user designates a structured document having a search function that he / she wants to browse from the portable terminal when going out or the like in advance.
(Referred to as W1) to obtain a structured document including the search result. The user selects an object to be viewed on the mobile terminal from the search result list.

For example, it is assumed that a structured document including a search result is analyzed by the document analysis means 103 as shown in FIG.
Note that the document analysis means 103 is
0 and / or screen analysis means 2030. 5 are the search results, the objects Y1, Y2,..., Y9 are the search result groups, and the objects at the lower hierarchy are the elements (title, content description, URL etc.)
And In the object specification, when the object is specified as shown in FIG. 6, the first object in the search result group is specified. When the object is specified by the hierarchy and rank as shown in FIG. Elements of each search result (eg title of each search result)
Is specified.

The information of the designated object is registered in the object registration means 105 of FIG. 28 together with the ID of the structured document having the search function (for example, in the case of a web document, the URL of the top page using a search engine). That is, the ID in this case is not a search result for the search term KW1, but an ID for the entire structured document (search result) output from the structured document having the search function. It is assumed that this ID is Z.

Next, when the user goes out, for example,
3, using a structured document having a search function of ID = Z, input a search term (KW2; may be different from KW1) and attempt to browse the search results (structured document) Suppose. The browsing request from the mobile terminal 13 is shown in FIG.
8 to the document acquisition means 101 via the communication network 12 and the communication means 100. Thereby, the document acquiring unit 101 stores the search term KW2 in the search term recording unit 50.
0 and the requested ID = Z, the search term K
The search result (structured document) of W2 is acquired from the document source 11.

On the other hand, the document analysis means 103 shown in FIG. 28 analyzes the structured document acquired by the document acquisition means 101 and detects the hierarchical structure of the object. The object specifying unit 108 specifies an object including information to be displayed on the mobile terminal 13 from the result of the object analysis performed by the document analyzing unit 103 and the information registered in the object registering unit 105.

For example, as shown in the example of FIG.
If the same rank and the same rank as 11 are specified,
From the obtained structured document, an object group having the same hierarchy and the same rank in the search result group is specified, and this object group is set as a display target object. However, ID =
Words used for search when using a structured document having a search function of Z, and object Y in search results
11 is different from the information registered at the terminal 10 at the time of the request for browsing from the portable terminal 13, even if the information that can uniquely identify the object Y11 in the document is stored in the document. If the analysis means 103 extracts and registers the information in the object registration means 105,
The object Y11 can be specified even when a different phrase is used or when the document is changed.

The document generating means 109 in FIG. 28 converts the structured document including the information in the object into the portable terminal 13 so that the information in the object specified by the object specifying means 108 can be browsed on the portable terminal 13. Generate in a format that can be displayed in. The structured document generated by the document generation unit 109 is transmitted to the mobile terminal 13 via the communication unit 100 and the communication network 12 and displayed on the display unit. As a result, the user of the mobile terminal 13
It is possible to browse only the information of the part specified by the terminal 10 without browsing all the search results by the structured document having the search function of D = Z.

Next, when the user goes out, for example,
Assume that an attempt is made to browse an arbitrary result (structured document) from a search result obtained by inputting the search term KW2 by using a structured document having a search function of ID = Z using No.3. Note that a browsing request for a plurality of results (structured documents) may be made at the same time.

The browsing request from the portable terminal 13 is as shown in FIG.
9 via the communication network 12 and the communication means 100. Accordingly, the document acquisition unit 101 acquires the requested structured document from the document source 11 via the communication network 12 and the communication unit 100, and the document analysis unit 103 analyzes the acquired structured document to obtain an object Detect the hierarchical structure of

The search term search means 501 in FIG. 29 searches for where the search term KW2 recorded in the search term recording section 500 is located in the hierarchical structure in the structured document.
Based on the output of the search phrase search unit 501, the document generation unit 109 searches for the search phrase K in the structured document to be viewed.
A process for specifying where W2 is located is performed. As a process for specifying the search phrase, for example, it is possible to simply describe the search phrase in different colors and sizes.

Further, since the structured document to be browsed has a large amount of information, if a process of dividing the structured document into a plurality of structured documents is performed, only the structured document in which the search term is described is transmitted to the portable terminal 13. indicate. Alternatively, the index document generation unit 3091 in the document generation unit 109 in FIG. 29 generates an index page that specifies where the search term KW2 is described in the structured document to be viewed.

For example, in the example of FIG. 30, among the objects in the structured document 5100 to which the user has made an access request from the search result obtained by using the search term KW2, the objects including the search term KW2 are X510 and X53.
Assume that it was 12. Further, since the information amount of the structured document 5100 is large, the document generation unit 109 performs a division process, and the structured document group 5 that can be browsed on the mobile terminal 13.
200 (document 5210, document 5220, document 5230,
It is assumed that the document is generated as the document 5240). Structured document 5
100 and the structured document group 520
The object X50 in the structured document 5210 of “0” corresponds, and the corresponding relationship of the other objects is the same.

In the example of FIG. 30, structured documents including objects X510 and X5312 including the search term KW2 are a document 5210 and a document 5240, respectively. 29 generates a structured document 5300 in which the access request links 5310 to the document group in the structured document group 5200 are displayed as a list. Search term KW2
Specify whether to include or not.

In the example of FIG. 30, the links to the structured documents (document 5210 and document 5240) containing the search term KW2 are indicated by a black star symbol, and the structured documents (document 5220 and The link to the document 5230) is described with a star symbol in the frame line, respectively, to clearly indicate whether or not the structured document at the link destination includes the search term KW2. In addition, a case where the number of the linked structured document including the search term is described, a case where information around the search term is described instead of describing the beginning of each document, and the like may be considered.

When there is a request to access a plurality of search results at the same time (an access request to k (arbitrary natural number) from the top of the search result list, a plurality of browsing targets using check boxes, etc. can be selected). The function is assumed to be included in the structured document of the search result list). For each document of the structured document group (the search result group requested by the user), the document analysis unit 103 and the search phrase recording are performed. Part 5
