Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information search technique via the Internet, and more particularly to an Internet information search technique suitable for efficiently performing a keyword search.

[0002]

2. Description of the Related Art At present, a so-called search site is used in order to efficiently search for desired information from a vast amount of information on the Internet. In this search site, a server for search is constructed as follows.

In general, the Internet has a large number of user terminals incorporated in a network, and information is transmitted and received between arbitrary user terminals incorporated in this network. When each user terminal accesses the Internet, It is performed via the provider with which each user terminal has a contract. The Internet access information of each user is stored and managed by this provider.

With the explosive popularity of the Internet in recent years, the number of providers, access points, and homepage sites has increased enormously. Therefore, it has become difficult for the user to search for desired information on the Internet.

[0005] As described above, a search site is provided on the Internet as a technique for assisting the user in searching for desired information from the Internet.
When searching for desired information on the Internet, the user
First, access the search site and enter the link information (URL: Uniform
Source Locator) is extracted and access to each Web page is performed to find the desired information.

[0006] Specifically, when performing an Internet search, a user uses a Web browser (hereinafter, referred to as "client") of a user terminal such as a personal computer.
Simply write "browser"), enter the URL of the target search site in the prescribed field on the window screen displayed by this browser, press the execution key, etc., and from the server device of the search site, The page display information of the search site is received, and the search site / page is displayed in a window.

On the displayed search site page, when the user inputs a keyword in a predetermined field, sets search conditions, etc., and instructs execution, the server device of the search site searches for homepage site information stored in the device itself. Then, the link information to each homepage site that matches the condition is extracted, and the list (including the URL, the homepage site name, the outline of the page contents, etc.) is returned to the browser side (client).

The browser displays this homepage site list, and the user accesses each homepage site in the homepage site list one by one to confirm the contents.

However, if the desired information is not found by accessing many times, problems such as an increase in search time and an increase in communication cost will occur. In order to solve such a problem, the search site determines the display order of each homepage site in each homepage site list based on the so-called hit rate.

For example, as described in Japanese Patent Application Laid-Open No. 1-149127, a database is accessed by a keyword designated by a user, and a search result retrieved by collation with an index word assigned to the database is Specified by using the exact match / partial match status between index words, keyword related words / match status between index words, appearance frequency of keywords in the search results, and the importance given to each index word that can be matched The matching degree (hit rate) of the content of the search result with respect to the keyword logical expression is given, and the search result, that is, the link information to each homepage site is displayed in order of the highest hit rate.

However, this hit rate does not always reflect the number of accesses with the keyword specified by the user, and the keyword is used to determine the display order of the link information on each homepage site based on this hit rate. It is not always the best one for the user.

That is, the hit rate of each homepage site is calculated based on the Web log file recorded by each Web server. An access log file indicating what kind of information has been transferred is recorded in this Web log file, and the count value of the number of records in this log file is used to calculate the hit rate. as a result,
For example, a web page consisting of one html file and two image files (gif) pasted there is one
When the access is made twice, the access log becomes “3”, and the hit rate that does not reflect the intention of the accessing user is calculated.

[0013]

The problem to be solved is that in the conventional technique, the user cannot quickly find the desired information from the list of link information displayed on the browser.

An object of the present invention is to solve these problems of the prior art and improve the convenience and reliability of the server device at the search site.

[0015]

In order to achieve the above object, in the present invention, a We that is hit in a search based on a keyword in response to a keyword search request from a browser is used.
In the search site server device that extracts the link information to page b and sends it to the browser, the popularity of each web page is obtained based on the access history to each web page, and the links to each web page are arranged in descending order of popularity. By sorting and sending the information to the browser, the link information is displayed on the browser in descending order of popularity. For example, the access history for each URL is registered in the storage device, and the access history is referred for each set period, and each UR for that period is referred to.
The number of accesses to L is totaled, the URLs are sorted in descending order of the number of accesses based on the totaled result, and the UR of the Web page hit by the search based on the keyword from the browser
By extracting L in the sort order and sending it to the browser, the link information is displayed in the browser in descending order of the number of accesses.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing a configuration example of an Internet system provided with a search site server device according to the present invention, and FIG. 2 is a search screen displayed on the display unit of the user terminal device shown in FIG. FIG. 3 is an explanatory diagram showing a configuration example of a menu page, FIG. 3 is an explanatory diagram showing a configuration example of a collection information table generated by the search site server device in FIG. 1, and FIG. 4 is a user terminal device and a search site server device in FIG. 8 is a flowchart showing an example of a display control operation of search information by the.

In FIG. 1, 1 is the Internet, 2 is a search site server device (described as "search site server device" in the figure), and 3a to 3d are server devices of respective providers ("provider A to N" in the figure). Description) 4 is a user terminal device.

The search site server device 2 is a device on the Internet 1 side, and is actually provided in the Internet 1.

The Internet of this example having such a configuration
In the system, the search site server device 2 extracts the link information to the Web page hit by the search based on the keyword in response to the keyword search request from the browser activated by the user terminal device 4, and the user terminal device 4 When sending to the browser, the display information of the search information is controlled so that the browser displays the link information in descending order of popularity.

That is, the search site server device 2 obtains the popularity of each web page based on the access history of each web page in the server devices 3a to 3d of each provider, and determines the popularity of each web page in descending order of popularity. By sorting the link information and sending it to the browser of the user terminal device 4, the link information is displayed on the browser in descending order of popularity.

In order to display the link information in the descending order of popularity in this way, the search site server device 2, for example, uses each W in the server devices 3a to 3d of each provider.
The access history to the eb page is acquired for each URL and registered in the recording device, the access history is referenced for each set period, and the number of accesses to each URL during the period is totaled, and based on the totaled result The URLs are sorted in descending order of access count, and the URLs of the Web pages hit by the search based on the keyword from the browser of the user terminal device 4 are extracted in the sorting order and sent to the browser.

Alternatively, the search site server device 2 extracts the URL of each Web page hit in the search based on the keyword from the browser of the user terminal device 4 and refers to the access history of each extracted URL to see the current URL. The number of accesses to each URL in a predetermined period is totaled, the URLs are sorted in descending order of the number of accesses based on the totaled result, and each sorted URL is sent to the browser.

Alternatively, when the search site server device 2 collects the number of times of access to each URL based on the access history in advance and extracts the URL of the Web page hit by the search based on the keyword from the browser of the user terminal device 4. , The extracted URLs are sorted in descending order of access count, and the sorted URLs are sent to the browser. As a result, in the browser of the user terminal device 4, the link information is displayed in descending order of the number of accesses,
Displayed in descending order of popularity.

The details of the search site server device 2 that performs such processing operations will be described below.

The search site server device 2, the server devices 3a to 3d of each provider, and the user terminal device 4 each include a CPU (Central Processing Unit), a main memory, a display device, an input device, an external storage device, and the like. By installing the program or data recorded in the storage medium of the CD-ROM into the external storage device via the optical disk drive, the program is read from the external storage device into the main memory and processed by the CPU. The following processing units are configured.

For example, the search site server device 2 is provided with a data collection unit 2a, a control unit 2b, and a display selection unit 2c, and the user terminal device 4 has an operation unit 4a and a control unit 4b.
A display unit 4c is provided.

The data collection unit 2a in the search site server device 2 collects access log information from the server devices 3a to 3d of the provider, and the display selection unit 2c selects a search page or the like to be provided to the user terminal device 4. Then, the control unit 2b controls the data collection unit 2a and the display selection unit 2
It controls the operation of the entire search site server device 2 including the activation and control with c.

The operation unit 4a of the user terminal device 4 is
The display unit 4c controls the instruction input from the user, and the display unit 4c displays the search site server device 2 and the server devices 3a to 3 of the provider.
It controls the display of the Web page sent from d.
The control unit 4b controls the operation of the entire user terminal device 4, including the activation / control of the operation unit 4a and the display unit 4c.

The server devices 3a to 3d of the provider are regularly or selectively accessed from the Internet 1 and, when accessed from the Internet 1, access to the data collection unit 2a of the search site server device 2 indicating that the data has been accessed. Log information (page address / URL,
Access date and time).

The search site server device 2 obtains the degree of popularity for each URL based on this access log information. For example, the number of times of access for each URL is counted and totaled, and the URLs are ranked as having a high rank and a high popularity.

Alternatively, the access log information supplied to the data collection unit 2a of the search site server device 2 includes the duration of each access, and the longer the duration, the higher the popularity.

When the user terminal device 4 accesses the search site server device 2 in order to request a search display result based on such popularity, for example, the control unit 4
b is one provider, the server device 3a of the provider
The search site server device 2 is accessed through one of 3d to 3d.

In the example shown in FIG. 1, the user terminal device 4
Although only one is shown in the figure, there are actually many user terminal devices for the Internet 1. Also, although only one search site server device 2 is shown, it is installed at a plurality of locations within the Internet 1.

When the user terminal device 4 accesses the Internet 1 via the server devices 3a to 3d of the provider, the access log information is recorded in the server devices 3a to 3d of the provider, and further, the server device of the provider. It is periodically sent from 3a to 3d to the search site server device 2.

In the search site server device 2, the data collection unit 2a collects the access log information for each provider identification information and access point information and collects it as an access history.

As described above, the access history collected by the data collection unit 2a is managed by the structure of the collection information table 31 as shown in FIG.

In the example of FIG. 3, in the data collection unit 2a of the search site server device 2, the access history information is generated once a day for a predetermined period, and each URL is
, Are sorted from top to bottom in descending order of number of accesses. The predetermined period for generating the access history information is one week or 10
It may be day by day.

As the processing of the data collection unit 2a of the search site server device 2, the access counts for each URL are simply added and recorded without ranking and managing as shown in FIG. It's just good.

In this case, the search site server device 2 extracts and narrows down each URL hit by the keyword in the control unit 2b every time a keyword search request is accessed from the user terminal device 4, for example. Ranking and sorting processing are performed based on the number of times of access for each URL.

The keyword search request operation from the user terminal device 4 to the search site server device 2 will be described below.

First, in the user terminal device 4, for example, "http: //www.nink" is displayed in a specific field on the browser screen displayed on the display unit 4c by the operation unit 4a.
When the URL "i.co.jp/" is entered and movement is specified,
The control unit 4b receives the URL (“http://www.ninki.co.jp”, for example, via the server device 3b of the provider (B).
Access the search site server device 2 specified by "/").

The search site server device 2 receives this access by the control unit 2b and reads the Web page (menu page) for search by the display selection unit 2c.
It is transmitted to the user terminal device 4.

The Web page for search (search menu page) thus transmitted from the search site server apparatus 2 has the structure shown in FIG.
Is displayed on the display screen 20 by the display unit 4c.

At this point, in the search menu page 21 having the configuration shown in FIG. 2, items such as “search execution button” and “condition” are displayed as the menu page. For example, search item input Information such as "Shogi" in the field and "Search results: 40" is not displayed.

In the search menu page 21 in this state, the user selects "Shogi" in the search item input field and "Popular U" in the condition input field via the operation unit 4a.
When "RL search" is input and execution is designated, the input information is transmitted to the search site server device 2.

Upon receiving this input information, the search site server device 2 first performs a normal keyword search by the control unit 2b to extract the URL of each hit Web page, and then the data collection unit 2a collects it. With reference to the collected information table 31 shown in FIG.
The extracted URLs are sorted in descending order of the number of accesses, link information corresponding to each URL is generated, and transmitted to the user terminal device 4.

The result of displaying the link information as the search result transmitted from the search site server device 2 on the user terminal device 4 in this way is the homepage site list screen shown in the search menu page 21 of FIG.

In the example of the search menu page 21 shown in FIG. 2, the link destination URL ("WW
W. syogi. co. jp ”,“ WWW.ama.c ”
o. jp ", ..." WWW.koba.co.jp "),
Name of the page as an outline of the URL ("Japanese Shogi Federation", "Ama Shogi Federation", ... "Kobayashi Shogi Life"), the number of yesterday's access to the URL page ("100,000",
"70,000", ... "5") are displayed.

The display contents are displayed from the upper side to the lower side in the descending order of the number of times of access yesterday, that is, in the descending order of popularity, and the user can display the Web pages hit by the keyword based on this display. You can search from the most popular pages. In general, a highly popular site is easier to find necessary information than a less popular site, so that the user can effectively search for desired information.

Next, the site search processing operation using the search site server device 2 and the user terminal device 4 in the Internet system shown in FIG. 1 will be described with reference to FIG.

First, in step S101, the user connects the user (user terminal device 4) and the search site (search site server device 2) to the Internet (1) via the provider (server devices 3a to 3d). The access information is also the server device (3a to 3d) of the provider.
Is stored as access log information and is supplied to the search site server device 2 regularly or arbitrarily.

Next, in step S102, the search site server device 2 determines whether or not the user has requested a search for site information in "popular URL search".
If it is a site information search by "popular URL search", the process proceeds to step S103, and if not, the process proceeds to step S104.

In step S103, the search site server device 2 sorts the information (home page name, URL, summary, etc.) of each site hit by the keyword search downwards in the order of higher access frequency and lower in the access frequency. , To the user terminal device 4, and the user terminal device 4 displays them in an order based on the sorting result.

The calculation of the high / low frequency of access in the search site server device 2 is similar to the access information in step S101, and the server devices 3a-3 of the provider.
This is performed based on the access log information accumulated in d.

Further, in step S104, the information (homepage name, URL, summary, etc.) of each site hit by the keyword search is searched for in the search site server device 2.
For example, it is arranged in the order based on the hit rate calculated by the conventional technique and transmitted to the user terminal device 4, and is displayed in the user terminal device 4 arranged in the order based on the hit rate.

In step S105, the user operating the user terminal device 4 lists the homepage sites displayed on the user terminal device 4 (homepage site name, link information to the site, summary of contents of the page, etc.). Based on the above), select one by one from the top of the list by the browser, access each homepage site, and check the contents.

In step S106, the user
If the user can find the target information, the process is branched depending on whether or not the target information can be found. If the user cannot find the target information, this series of flowcharts is terminated. Then, the process returns to step S102, and the processes after step S102 are repeatedly executed.

With this processing operation, when the user terminal device 4 accesses the search site server device 2, the user can easily find the desired information. That is, since a site with high popularity is easier to find necessary information than a site with low popularity, by displaying search results on the browser from the top in the order of popularity, the user can obtain the desired information. You can easily find it.

As described above with reference to FIGS. 1 to 4, in this example, the search site server device 2 responds to a keyword search request from the browser of the user terminal device 4.
When extracting the link information to the Web page hit by the search based on the keyword and sending it to the browser,
Each W supplied from the server devices 3a to 3d of the provider
Based on the access history (log information) to the eb page, for example, the popularity of each Web page is calculated based on the number of times the access is made, the length of the access time, or the like. By sorting the link information to the Web page and sending it to the browser of the user terminal device 4, the browser of the user terminal device 4 displays the link information in descending order of popularity, for example, from top to bottom.

In this way, on the browser screen, the link information to each site hit by the keyword is displayed from the top in the descending order of popularity, and a site with high popularity is required as compared with a site with low popularity. Since it is easy to find the desired information, the user can quickly find the desired information.

The present invention is not limited to the examples described with reference to FIGS. 1 to 4, and various modifications can be made without departing from the scope of the invention. For example, in this example,
As the information indicating the popularity, an example in which the number of accesses and the access time in a predetermined period are used is shown. However, by providing a field for inputting an evaluation of the page from the user on the page, the information from each user can be provided. The direct evaluation may be used to calculate the popularity of each page.

The computer configuration of each device in this example may be a computer configuration without an optical disk drive device. Further, in this example, the CD-ROM is used as the program recording medium, but the FD (Flex
ible disk) or the like may be used as the recording medium.
Further, regarding the installation of the program, the program may be downloaded and installed via the network via the communication device.

[0064]

According to the present invention, the link information to each site hit by the keyword specified by the user on the browser can be displayed from the top in descending order of popularity.
Compared to less popular sites, more popular sites are more likely to find the information they need, which makes it easier for users to find the information they want, and the convenience and reliability of the Internet information retrieval system. Can be improved.
