Description

  The present invention relates to an information providing method, an information providing apparatus, an information providing system, and a computer program that provide information resources in response to a request from a communication terminal device, particularly when a character string indicating the location of the information resources is erroneously input. However, it is possible to provide a user-desired information resource by generating a character string candidate that correctly indicates the location of the information resource and re-searching the information resource, and providing the information providing method. The present invention relates to an apparatus, an information providing system including the information providing apparatus, and a computer program that causes a computer to execute an information providing method.

  With the spread of Internet technology, it has become possible to access various information resources on the Internet, such as hypertext documents and image information, from communication terminal devices. Specifically, information resources on the Internet are stored in an information providing apparatus connected to a communication network. The communication terminal device accepts a URL (Uniform Resource Locator) indicating the location of the information resource by the browser. The URL is expressed, for example, as “http://host.co.jp/bokujou/teto.htm”, the domain name “host.co.jp” identifying the information providing apparatus on the Internet, and the information resource of the information providing apparatus A path name “bokujou / teto.htm” indicating the location is included. The communication terminal device accesses the information providing device indicated by the domain name “host.co.jp” of the URL, and requests the provision of the information resource indicated by the path name “bokujou / teto.htm”. The information providing device searches for the information resource based on the character string “bokujou / teto.htm” indicating the location of the information resource, and transmits the searched information resource to the communication terminal device. The communication terminal device receives the information resource transmitted from the information providing device, and outputs a document, an image, and the like related to the information resource with a browser.

  On the other hand, there has been proposed a communication system that enables access to information resources without making the user aware of long and complicated URLs (for example, Patent Documents 1 and 2). The communication systems according to Patent Documents 1 and 2 include a URL search server that stores a correspondence between a predetermined character string and URL that is easy for the user to understand. When the communication terminal device cannot access the target information resource with the input character string, the communication terminal device transmits the character string to the URL search server. The URL search server converts the character string into a URL corresponding to the character string, and transmits the converted URL to the communication terminal device. The communication terminal device accesses a specific information resource using the converted URL.

In the communication systems according to Patent Documents 1 and 2, information resources desired by the user can be provided without making the user aware of long and complicated URLs.

  An information providing apparatus according to a third aspect of the present invention provides a request unit that requests the transmission source to retransmit a character string indicating the location of an information resource when the search unit fails to search for an information resource. When the receiving unit receives the character string transmitted from the transmission source in response to the request and succeeds in searching for the information resource based on the received character string, the erroneously input character string and the correct input character string related to the character string Are associated with each other and registered in the erroneously input character string dictionary.

  An information providing apparatus according to a fourth invention is characterized by comprising means for transmitting a hyperlink including a character string generated by the generating means to the transmission source.

  In the information providing apparatus according to a fifth aspect of the invention, the erroneous input character string dictionary stores erroneous input number information relating to the number of erroneous inputs in association with the positive input character string and the erroneous input character string, When the generation unit generates a plurality of character strings and the search unit re-searches a plurality of information resources, the number of erroneous inputs corresponding to the positive input character string and the erroneous input character string used to generate the character string It comprises selection means for selecting one information resource based on information, and means for transmitting the information resource selected by the selection means to the transmission source.

  In the information providing apparatus according to the sixth aspect of the invention, the storage means stores a character string of each of a plurality of extensions indicating the data format of the information resource, and the generation means searches the information resource by the search means. In case of failure, the character string of the extension stored in the storage means is added to the character string received by the receiving means, or a part of the character string received by the receiving means is replaced with the character string of the extension. Means are provided.

  According to a seventh aspect of the present invention, in the information providing apparatus, the storage means associates a character string expressed in non-phonetic characters with a character string expressed in phonograms. And when the search means fails to search for information resources, the generation means is based on the character string received by the reception means and the phonetic character dictionary stored in the storage means. A means for generating a character string in which a part or all of the character string is changed is provided.

  An information providing system according to an eighth invention is an information providing system comprising a communication device connected via a communication network and any one of the information providing devices according to the second to seventh inventions, wherein the communication device includes: Means for transmitting a character string indicating the location of the information resource to the information providing apparatus, wherein the information providing apparatus receives the character string transmitted from the communication apparatus and transmits the information resource relating to the character string to the communication apparatus; It is characterized by being provided to.

  A computer program according to a ninth aspect of the present invention is a computer program for receiving a character string indicating the location of an information resource and causing a computer that provides the information resource to a transmission source of the character string to search for the information resource based on the character string. A part of or all of the character string received by the computer, the erroneously input character string that failed to retrieve the information resource, and a part or all of the character string received after receiving the character string, the information If the computer fails to search for an information resource, an incorrect input string dictionary that associates a positive input string that has been successfully searched for resources is created, and based on the received character string and the erroneous input string dictionary. A character string in which a part or all of the character string is changed is generated, and the computer is caused to re-search information resources based on the generated character string.

  In the first, second, eighth and ninth inventions, when the retrieval of the information resource based on the received character string fails, the character string of the character string is determined based on the received character string and the erroneously input character string dictionary. A character string that is partially or wholly changed, that is, a character string that correctly indicates the location of the information resource is generated. The erroneously input character string dictionary is a part or all of the received character string, and includes an erroneously input character string that failed to search for information resources and a part or all of the character string received after receiving the character string. Thus, a positive input character string that has been successfully searched for information resources is associated. Since the erroneous input character string dictionary indicates the tendency of erroneous input of the character string, it is possible to generate a character string that correctly indicates the location of the information resource from the erroneously input character string. Then, the information resource is searched again based on the generated character string, and when the information resource is searched again, the information resource is transmitted to the transmission source.

  Therefore, even when a character string indicating the location of the information resource is erroneously input, it is possible to estimate the character string that correctly indicates the location of the information resource and to provide the information resource desired by the user.

  In the third and eighth inventions, when the request unit fails to search for the information resource based on the received character string, the request unit retransmits the character string indicating the location of the information resource to the transmission source of the character string. Request. When the receiving unit receives the character string transmitted from the transmission source in response to the request from the requesting unit and succeeds in retrieving the information resource based on the received character string, the erroneously input character string and the correct character string related to the character string are stored. The input character string is associated and registered in the erroneous input character string dictionary. That is, every time a character string is erroneously input, information regarding the erroneously input character string and the correct input character string related to the character string is accumulated in the erroneously input character string dictionary.

  Accordingly, it is possible to improve the generation accuracy of the character string that correctly indicates the location of the information resource, and to provide the information resource desired by the user more accurately.

  In the fourth and eighth inventions, the hyperlink including the character string generated by the generation unit is transmitted to the transmission source.

  Therefore, information resources desired by the user can be provided by hyperlinks. On the transmission side, it is possible to acquire a desired information resource simply by selecting the hyperlink using a browser. This is particularly effective when a plurality of character strings are generated by the generation means.

  In addition, since the sender can transmit the correct character string intended by the user to the information providing device simply by selecting the hyperlink using a browser, it is possible to re-create the character string by manual input which is troublesome. Compared with the case where transmission is requested, the information providing apparatus can more effectively collect information related to the erroneous input tendency of the character string and register it in the erroneously input character string dictionary.

  In the fifth and eighth inventions, the erroneous input character string dictionary stores the erroneous input number information related to the erroneous input number in association with the positive input character string and the erroneous input character string. When a plurality of information resources desired by the user are searched, the selection means selects one information resource based on the erroneous input count information. For example, an information resource having the highest possibility of erroneous input is selected.

  Therefore, it is possible to select and provide one information resource that is highly desired by the user.

  In the sixth and eighth inventions, by adding the character string of the extension stored in the storage means to the character string received by the receiving means, even when no extension is input, The generation means can generate a character string that correctly indicates the location of the information resource.

  Even if the extension is erroneously input, the generating unit replaces part of the character string received by the receiving unit with the character string of the extension stored in the storage unit. It is possible to generate a character string that correctly indicates the location of.

  In the seventh and eighth inventions, the generation means correctly indicates the location of the information resource even when the character string to be written in non-phonetic characters is written in phonetic characters. A string can be generated.

  Therefore, even when a character string in which the part that should be expressed in non-phonetic characters is received in phonetic characters is received, a character string that correctly indicates the location of the information resource is estimated, and information desired by the user is estimated. It becomes possible to provide resources. That is, it becomes possible to request an information resource by using a character string in which a non-phonetic character part that is easily input erroneously at the transmission source is represented by a phonetic character.

  According to the first, second, eighth, and ninth inventions, even if a character string indicating the location of the information resource is erroneously input, the character string that correctly indicates the location of the information resource is estimated, and the user's desired Information resources.

  According to the third and eighth inventions, it is possible to improve the generation accuracy of the character string correctly indicating the location of the information resource, and to provide the user-desired information resource more accurately.

  According to the fourth and eighth inventions, information resources desired by the user can be provided by hyperlinks.

  Also, when requesting retransmission of a character string indicating the location of an information resource, information relating to the tendency of erroneous input by a user is collected more effectively than when requesting retransmission of a character string through manual input that is time-consuming. be able to.

  According to the fifth and eighth inventions, it is possible to select and provide one information resource that is highly likely to be desired by the user.

  According to the sixth and eighth inventions, even when the extension is not input or when the extension is erroneously input, the character string correctly indicating the location of the information resource is estimated, and the user's desired Information resources can be provided.

  According to the seventh and eighth inventions, the character string correctly indicating the location of the information resource is obtained even when the character string in which the portion to be expressed in non-phonetic characters is received in phonogram characters is received. It is possible to estimate and provide information resources desired by the user.

  FIG. 6 is a block diagram schematically showing the configuration of the communication terminal device 3. The communication terminal device 3 is a computer including a CPU 30 that controls the entire device. The CPU 30 communicates various information with the ROM 31, the RAM 32, the external storage device 33, the internal storage device 35, the input device 34 such as a mouse and a keyboard, the output device 36 such as a liquid crystal display and a CRT, and the information providing device 1. A communication unit 37 is connected through a bus 38.

  The ROM 31 and the internal storage device 35 store programs necessary for the operation of the CPU 30, and the CPU 30 reads the programs stored in the ROM 31 and the internal storage device 35 into the RAM 32 and executes them, thereby executing a hypertext transfer protocol. A browser function that requests the information providing apparatus 1 to transmit information resources, receives the information resources transmitted from the information providing apparatus 1, and outputs image information, character information, voice information, and the like related to the received information resources. Realize.

  7 and 8 are flowcharts showing the processing procedure of the CPU 10 for providing information. The CPU 10 of the information providing apparatus 1 receives the character string indicating the location of the information resource at the first communication unit 17 (step S11).

  Specifically, on the communication terminal device 3 side, the CPU 30 displays the browser screen 5 on the output device 36 (see FIG. 9), and accepts a URL from the browser screen 5 by the input device 34. The URL is expressed, for example, as “http://host.co.jp/bokujo/teto.htm”. The URL includes a scheme name “http”, a host name “host.co.jp”, and a path name “bokujou / teto.html”, and indicates the location of the information resource. The path name indicates the location of the information resource in the information providing apparatus 1 and includes a folder name and a file name. Needless to say, the path name may be composed of only the file name.

  FIG. 9 is a schematic diagram illustrating an example of the browser screen 5. The browser screen 5 includes a URL input unit 50 for inputting a URL and an information resource display unit 51 for displaying a hypertext document, an image, and the like related to the information resource. The CPU 30 corresponds to the host name “host.co.jp” when the URL is input to the URL input unit 50, for example, when the URL “http://host.co.jp/bokujo/te” is input. An inquiry is made to a DNS (Domain Name System) (not shown) for an IP address, for example, the IP address of the information providing apparatus 1. Then, the CPU 30 establishes a connection with the information providing apparatus 1 using the IP address returned from the DNS. Next, the CPU 30 transmits a character string indicating the location of the information resource in the information providing apparatus 1, that is, a path name “bokujo / te”, and information requesting transmission of the information resource to the information providing apparatus 1 through the communication unit 37. . Then, the CPU 10 of the information providing apparatus 1 receives the character string at the first communication unit 17.

  When the process of step S11 is completed, the CPU 10 searches for a specific information resource stored in the internal storage device 15 based on the received character string (step S12). And CPU10 determines whether the search of the information resource based on the character string received by step S11 was successful (step S13).

  When it is determined that the search of the information resource is successful (step S13: YES), the CPU 10 transmits the searched information resource to the communication terminal device 3 by the first communication unit 17 (step S14), and relates to information provision Finish the process.

  If it is determined that the information resource search has failed (step S13: NO), the CPU 10 stores the character string that has failed in the information resource search, that is, the character string erroneously input on the communication terminal device 3 side in the RAM 12 ( Step S15). The RAM 12 temporarily stores, for example, a character string “bokujo / te”.

  Next, the CPU 10 calls and executes a subroutine to generate a character string candidate that correctly indicates the location of the information resource (hereinafter referred to as a positive input character string candidate) (step S16).

  FIG. 10 is a flowchart showing a processing procedure of a subroutine relating to generation of a positive input character string candidate. The CPU 10 unifies the character types of the character strings received in step S11 (step S31). For example, double-byte characters are unified into single-byte characters.

  Next, the CPU 10 extracts the character string of the Roman character notation from the character string (step S32). Then, the CPU 10 transmits the extracted character string of the Roman character notation part to the dictionary server 2, obtains the English character string corresponding to the character string, and replaces the character character string of the Roman character notation with the English character string. (Step S33). For example, when the character string “biru.html” is received, the character string “biru” in the Roman character notation is changed to “beer”.

  Next, the CPU 10 extracts the character string of the folder name portion from the character string processed in steps S31 to S33 (step S34). Then, the CPU 10 transmits the extracted character string of the folder name portion to the dictionary server 2, and acquires the correct input character string and the number of erroneous inputs related to the character string (step S35). That is, one or a plurality of positive input character strings that are the same as the extracted character string or associated with an erroneous input character string that includes the character string, and an erroneous input that is associated with the erroneous input character string and the positive input character string Get the number of times. For example, when the character string “bokujo / te” is received, “bokujo” is extracted as the folder name portion. Then, the correct input character string “bokujou” and the erroneous input count 55 related to “bokujo”, the correct input character string “bokujyou” and the erroneous input count 10 are acquired.

  Next, the CPU 10 extracts the character string of the file name portion from the character string processed in steps S31 to S33 (step S36). Then, the CPU 10 transmits the extracted character string of the file name portion to the dictionary server 2, and acquires the correct input character string and the number of erroneous inputs related to the character string of the file name portion (step S37). That is, one or a plurality of positive input character strings that are the same as the extracted character string or associated with an erroneous input character string that includes the character string, and an erroneous input that is associated with the erroneous input character string and the positive input character string Get a string. For example, when the character string “bokujo / te” is received, “te” is extracted as the file name portion. Then, the correct input character string “tes” and the erroneous input count 8 corresponding to “te”, the correct input character string “teto”, and the erroneous input count 66 are acquired.

  Next, the CPU 10 generates a character string in which the folder name and the file name portion of the character string are replaced with the positive input character string acquired in step S35 and step S37 (step S38). For example, when the character string “bokujo / te” is received, the character strings “bokujo / tes”, “bokujo / teto”, “bokujou / tes”, and “bokujyou / teto” are generated.

  Then, the CPU 10 extracts the character string of the extension portion from each character string generated in step S38 (step S39), and extracts the extension portion of the character string for each of a plurality of extensions registered in the extension dictionary 2c. If the character string is replaced or the extension portion is not extracted, the extension character string is added (step S40), and the process ends. For example, when a character string “bokujo / te” is received, a character string to which a character string with various extensions is added, for example, “bokujo / tes.html”, “bokujo / tes.html”, “bokujo / tes.sml ”,...“ bokujyou / teto.php ”,“ bokujyou.pl ”, etc. are generated.

  When the process of step S16 is completed, the CPU 10 searches for information resources again based on the character string of the positive input character string candidate generated in step S16 (step S17). For example, if the internal storage device 15 stores an information resource specified by a character string “bokujou / teto.html” and an information resource specified by a character string “bokujou / tes.html”, The information resource is searched again.

  Then, the CPU 10 determines whether or not the information resource re-search is successful (step S18).

  If it is determined that the re-search of the information resource is successful (step S18: YES), the CPU 10 selects one information resource, for example, the information resource that maximizes the erroneous input probability based on the erroneous input frequency information (step S19). ). For example, in the case of the character string “bokujou / teto.htm”, the number of erroneous inputs of “bokujou” is 55 and the number of erroneous inputs of “teto” is 66, so that the erroneous input probability can be evaluated as 55 × 66. . Similarly, in the case of the character string “bokujou / tes.html”, the number of erroneous inputs of “bokujou” is 55, and the number of erroneous inputs of “tes” is 8, so that the erroneous input probability can be evaluated as 55 × 8. it can. Therefore, the information resource specified by “bokujo / teto.htm” is selected as one information resource with a high possibility of erroneous input.

  Then, the CPU 10 displays the hyperlink including the character string that has been successfully re-searched for the information resource in step S17, the one information resource selected in step S19, and requests retransmission of the character string indicating the location of the information resource. To generate information resources (step S20). For the hyperlink, a character string “http://host.co.jp” indicating the scheme name and the host name of the information providing device 1 is added to the head of the generated character string “bokujou / teto.htm”. It is a thing. The character string “http://host.co.jp” is stored in the internal storage device 15 of the information providing device 1.

  If it is determined that the information resource re-search has failed (step S18: NO), the CPU 10 displays the information resource on the top page, for example, the information resource specified by the path name “index.html”, and the location of the information resource. An information resource for requesting retransmission of the character string indicating “” is generated (step S21).

  When the process of step S20 or step S21 is completed, the CPU 10 transmits the information resource generated in step S20 or step S21 to the communication terminal device 3 in the first communication unit 17 (step S22).

  FIG. 11 is a schematic diagram showing an example of a browser screen 5 displaying a hyperlink presumed to be desired by the user and one information resource. When the communication unit 37 receives the information resource generated in step S20, the CPU 30 of the communication terminal device 3 displays the browser screen 5 as shown in FIG. 11 on the output device 36 based on the information resource. The information resource display unit 51 of the browser screen 5 is divided into an upper frame 51a and a lower frame 51b. A hyperlink is displayed on the upper frame 51a, and it is estimated that the user desires the lower frame 51b. One information resource is displayed. In the upper frame 51a, “This page does not have a page of http://host.co.jp/bokujo/te that has been input, so a page that seems to be intended is automatically searched and displayed. * The following candidate page exists at this URL. " The hyperlink is displayed below the explanatory text. In addition, an explanatory note “(currently displayed)” is displayed at one end in the horizontal direction of the hyperlink of the information resource displayed in the information resource display unit 51. Further, below the hyperlink, an explanatory note “If these pages are the intended pages, click the link to see the pages.” Is displayed.

  Next, the CPU 10 determines whether or not the character string transmitted from the communication terminal device 3 has been received in response to the character string re-transmission request indicating the location of the information resource (step S23).

  Specifically, on the communication terminal device 3 side, the CPU 30 accepts re-input of a character string with the input device 34. When a hyperlink indicating the location of the information resource intended by the user is displayed on the browser screen 5, the user simply provides information on the character string indicating the location of the information resource by selecting the corresponding hyperlink. It can be retransmitted to the device 1. When the hyperlink indicating the location of the information resource intended by the user is not displayed on the browser screen 5, the user inputs the character string indicating the location of the information resource to the URL input unit 50, thereby Is retransmitted to the information providing apparatus 1. Then, the CPU 10 of the information providing apparatus 1 receives the character string at the first communication unit 17.

  If it is determined that the character string corresponding to the retransmission request has not been received (step S23: NO), the CPU 10 determines whether or not a predetermined time has elapsed since the information resource was transmitted in step S22 (step S25). . When it determines with predetermined time not having passed (step S25: NO), CPU10 returns a process to step S23. If it is determined that the predetermined time has elapsed (step S25: YES), the CPU 10 ends the process related to information provision.

  If it is determined that the character string corresponding to the retransmission request has been received (step S23: YES), the CPU 10 searches for the information resource based on the received character string (step S24), and whether or not the information resource has been successfully searched. Is determined (step S26).

  If it is determined that the information resource search has failed (step S26: NO), the CPU 10 returns the process to step S15. When it is determined that the information resource search is successful (step S26: YES), the CPU 10 transmits the information resource searched in step S24 to the communication terminal device 3 in the first communication unit 17 (step S27).

  12 and 13 are schematic views showing an example of the browser screen 5 displaying information resources. For example, when the hyperlink of the URL “http://host.co.jp/bokujo/teto.html” is selected on the communication terminal device 3 side, the characters “bokujou / teto.html” as shown in FIG. Information resources searched in the column are displayed on the information resource display unit 51. More specifically, the information providing device 1 receives the character string “bokujou / teto.htm” transmitted from the communication terminal device 3, searches the information resource based on the character string, and searches for the searched information resource. It transmits to the communication terminal device 3. The communication terminal device 3 receives the information resource transmitted from the information providing device 1 and causes the information resource display unit 51 to display the information resource based on the received information resource.

  Similarly, when the hyperlink of the URL “http://host.co.jp/bokujou/tes.html” is selected, the character string “bokujou / tes.html” is searched as shown in FIG. The information resource is displayed on the information resource display unit 51.

  Next, the CPU 10 calls a subroutine to register the erroneously input character string dictionary 2a (step S28), and finishes the processing related to information provision.

  FIG. 14 is a flowchart showing a processing procedure of the CPU 10 related to registration of an erroneously input character string and a correct input character string. The CPU 10 extracts the character string of the folder name portion and the file name portion of the character string that has been successfully searched for the information resource (step S51). For example, when the character string “bokujou / teto.htm” is received, the folder name “bokujou” and the file name “teto” are extracted.

  Next, the CPU 10 specifies an erroneously input character string and a correct input character string (step S52). For example, the folder name part “bokujo” of the character string “bokujo / te” that has failed in the information resource search is compared with the folder name part “bokujo” of the character string that has been successfully searched for the information resource. If it is, “bokujo” is specified as the erroneously input character string, and “bokujo” is specified as the correct input character string. Similarly, the file name portion “te” of the character string “bokujo / te” that has failed in the search of the information resource is compared with the file name portion “teto” of the character string that has been successfully searched for the information resource, and an incorrect input character is detected. “Te” is specified as a column, and “teto” is specified as a positive input character string.

  Next, the CPU 10 transmits the erroneous input character string and the positive input character string specified in step S52 to the dictionary server 2, and determines whether or not there is the same erroneous input character string and the positive input character string (step S53). . When it is determined that there is the same erroneous input character string and positive input character string (step S53: YES), the corresponding erroneous input count is increased (step S54), and the process is terminated. For example, when the erroneous input character string “te” and the positive input character string “teto” are transmitted to the dictionary server 2, the corresponding erroneous input count “66” is increased to “67”.

  If it is determined that there is no identical erroneously input character string (step S53: NO), the CPU 10 newly registers the erroneously input character string and the correct input character string in the erroneously input character string dictionary 2a (step S55), and ends the process. .

  In the information resource providing system, the information providing apparatus 1, the information providing method, and the computer program according to the embodiment configured as described above, a character string indicating the location of the information resource is erroneously input on the communication terminal apparatus 3 side. Even in such a case, it is possible to estimate a correct character string that can access the user-desired information resource and to provide the user-desired information resource to the communication terminal device 3.

  Further, when the character string indicating the location of the information resource is erroneously input, the erroneous input character string and the correct input character string are specified and registered in the erroneous input character string dictionary 2a. It is possible to learn an erroneous input tendency, improve the generation accuracy of a character string that correctly indicates the location of the information resource, and more accurately provide the information resource desired by the user.

  Furthermore, it is possible to estimate a correct character string that can access the information resource desired by the user, and provide a hyperlink including the character string. A user can obtain a desired information resource only by selecting a hyperlink.

  In addition, when requesting retransmission of a character string that correctly indicates the location of the information resource, information related to the tendency of erroneous input by the user is more effective than when requesting retransmission of the character string by manual input. To learn the erroneously input character string dictionary 2a.

  Furthermore, since the information resource selected based on the character string having the highest probability of erroneous input is provided, the information resource that is likely to be desired by the user is selected. Can be provided.

  Furthermore, even when the extension is not input or when the extension is input incorrectly, a character string that correctly indicates the location of the information resource is estimated, and the information resource desired by the user can be provided. it can.

  Furthermore, even when a character string in which a portion that should be expressed in non-phonetic characters is received as a phonetic character is received, a character string that correctly indicates the location of the information resource is estimated, and a user-desired character string is estimated. Information resources can be provided.

  In the embodiments, hypertext documents, image information, and the like have been described as information resources. However, the contents of the information resources are not limited to this, and include various types of information that can be searched based on character strings. . For example, the information resource may be an IP address of a communication device connected to a communication network, and the information providing method according to the present invention may be applied to DNS. According to the DNS that implements the information providing method, even when the domain name is entered incorrectly, for example, when “hos.co.jp” is entered incorrectly, the correct character string “host.co.jp” is entered. The IP address as an information resource is searched based on the estimated character string “host.co.jp”, and the searched IP address can be transmitted to the communication terminal device that requested the IP address.

  Further, the CPU of the information providing apparatus implements the information providing method according to the present invention. Needless to say, the processing related to the information providing method may be distributed using a plurality of computers. For example, you may comprise so that a dictionary server may perform a part of process which CPU of an information provision apparatus is performing.

  Furthermore, although a dictionary server storing an erroneously input character string dictionary, a Roman character notation dictionary, and an extension dictionary has been described as an example, it may be linked with another dictionary such as a Japanese dictionary.

  Furthermore, the embodiments disclosed herein are illustrative in all respects and are not restrictive. The scope of the present invention is defined by the terms of the claims, and includes all modifications within the scope and meaning equivalent to the terms of the claims.
