Description

  The present invention relates to a tag cloud composition device and method that can expand and contract a character string length.

  In recent search systems, a web page related to a keyword input to a terminal is provided, and words associated with the keyword are presented as a search result. An example of this is “tag cloud”. Here, “tag” refers to a character string that classifies a linked web page, and “tag cloud” refers to a predetermined tag such as a display screen that includes a plurality of tags including hyperlinks to linked web pages. The one represented in the area. When the tag cloud is used, a plurality of words associated with the keyword are presented, but the font size of the presented word is different. The size of the font corresponds to the number of Web pages related to the word, and the larger the font, the larger the number of Web pages related to the word.

  As an apparatus using a tag cloud, there is known an apparatus that presents not only words associated with one keyword but also words associated with a plurality of keywords in common (for example, see Patent Document 1). According to this apparatus, it is possible to find words that are closely related to all of a plurality of keywords input by a user with a single operation.

JP 2009-86903 A

  However, in the apparatus described in Patent Document 1, as shown in FIG. 11 of Patent Document 1, a large number of words associated with keywords (22 words in FIG. 11) are only presented over the entire search screen. Therefore, if the meaning of a word is too simple and too wide, or if it can have multiple meanings, the user who sees it does not know which word to select because the image is not fixed, and it is desirable It may be difficult to find the web page. In addition, as a result of insufficient search conditions, it may be uncomfortable that it takes a long time to find a desired Web page.

  It is an object of the present invention to provide a tag cloud configuration device and method that can make a search system using a tag cloud easier to use and can further suppress the time until a desired web page is found, and that can expand and contract a character string length. To do.

  The present invention provides the following solutions.

  (1) In response to receiving a tag cloud page transmission request from a tag cloud database in which tags having different character string lengths and URLs of linked documents are stored in association with each other and a terminal connectable via a communication network, Tag cloud configuration means for reading out the tag from a tag cloud database and forming a tag cloud of a predetermined character string length using a larger character as the number of URLs of the linked document associated with the tag cloud increases, and the tag cloud Tag cloud page transmission means for transmitting a tag cloud page including a tag cloud configured by the configuration means to the terminal, and tag cloud expansion / reduction request reception means for receiving a request for expansion / reduction of the character string length of the tag cloud from the terminal When the request to expand the tag cloud character string length is received, When a tag having a character string length longer than the predetermined character string length is read from the tag cloud database, the tag cloud is reconfigured, and a request for shortening the character string length of the tag cloud is received, the tag cloud database A tag cloud reconstruction unit that reads out a tag having a character string length shorter than the predetermined character string length to reconfigure the tag cloud, and a tag cloud page including a tag cloud configured by the tag cloud reconstruction unit. A tag cloud configuration device comprising tag cloud page update transmission means for transmitting to a tag cloud.

  According to the invention described in (1), the tag cloud decompression / shortening request accepting unit accepts a request for decompressing / shortening the character string length of the tag cloud from the terminal. When the tag cloud reconstruction unit accepts a request to extend the character string length of the tag cloud, the tag cloud reconstruction unit reads a tag having a character string length longer than the predetermined character string length from the tag cloud database and reconfigures the tag cloud. . On the other hand, when a request for shortening the character string length of the tag cloud is received, a tag having a character string length shorter than a predetermined character string length is read from the tag cloud database to reconfigure the tag cloud.

  According to the present invention, when the meaning of the tag displayed on the terminal is simple and too wide, or when the tag may have a plurality of meanings, the user makes a request to expand the character string length of the tag cloud from the terminal. Since the tag image is determined by visually recognizing the tag cloud having a longer character string length, it is possible to easily find a desired web page as compared with the conventional search system, and as a result, find the desired web page. Can be suppressed. Conversely, if the tag character string displayed on the terminal is too long, the number of tags that can be displayed in a finite display space is limited, or if the user does not know which tag to select, By making a request for shortening the character string length of the tag cloud from the terminal, it is possible to display more tags using a vacant display space, and to acquire information about tags widely. Therefore, it is possible to provide a tag cloud constituent device that can more easily use a search system that uses a tag cloud and that can further reduce the time until a desired Web page is found, and that can expand and contract the character string length.

  (2) For the tag cloud after the reconfiguration, the tag cloud reconstructing unit includes a number of link destination documents in which the number of character strings of a part of the expanded / shortened tag is different from the character strings of other parts. When the tag cloud database is associated with a URL and stored in the tag cloud database, the tag cloud is reconfigured using a character having a larger character string in a portion where the number of URLs of the linked document is larger. Tag cloud configuration device.

  According to the invention described in (2), the tag cloud constituent device stores a character string of a part of the tag in the tag cloud database in association with a different number of URLs of linked documents from a character string of the other part. In this case, in the same tag, the difference in the number of linked documents in the character string of each part can be expressed by the difference in character size. As a result, the user can easily grasp the difference in the number of linked documents depending on the size of the character used in the character string of each part of the tag, which makes it easier to use the search system using the tag cloud, It is possible to provide a tag cloud constituent device that can further reduce the time until finding a desired Web page and that can expand and contract the character string length.

  (3) The tag cloud reconfiguring unit, when the character strings of a part of the plurality of tags expanded / shortened are the same for the tag cloud after the reconfiguration, The tag cloud configuration according to (1) or (2), in which a character string is shared, a character string of a part other than the same part of the character string is arranged before or after the character string, and the tag cloud is reconfigured apparatus.

  According to the invention described in (3), when a part of character strings of the plurality of tags is the same, the tag cloud constituent device shares the part of the same character string, Alternatively, a tag cloud can be configured by arranging character strings of other parts later. Accordingly, the user can visually recognize the same partial character string and a plurality of other character strings as a series of character strings. Therefore, the user can more easily use a search system using a tag cloud by visually recognizing a plurality of tags including a part of the same character string as a series of character strings, and find a desired Web page. It is possible to provide a tag cloud configuration device capable of further reducing the time and capable of expanding and contracting the character string length. Further, by forming a tag cloud by sharing a part of the same character string, it is possible to save space and display many tags in a limited display space.

(4) A tag comprising tag cloud database creation means, tag cloud construction means, tag cloud page transmission means, tag cloud expansion / reduction request acceptance means, tag cloud reconfiguration means, and tag cloud page update transmission means A tag cloud database that creates a tag cloud database by associating tags with different character string lengths and URLs of linked documents performed by the tag cloud database creation unit , which is a method of configuring a tag cloud performed by a cloud configuration device In response to accepting a tag cloud page transmission request from a terminal that can be connected via a communication network, which is performed by the creation step and the tag cloud configuration unit, the tag is read from the tag cloud database and associated The number of URLs of the linked document is A tag cloud configuration step to configure the tag cloud by a predetermined string length tags using Ihodo large character, the tag cloud page sending means performs, tag cloud containing tag cloud constructed by the tag cloud configuration process Tag cloud transmission step for transmitting a page to the terminal, and tag cloud expansion / reduction request reception step for receiving a request for expansion / reduction of the character string length of the tag cloud from the terminal , performed by the tag cloud expansion / reduction request reception unit And when the tag cloud reconstruction unit receives a request to extend the character string length of the tag cloud, reads out a tag having a character string length longer than the predetermined character string length from the tag cloud database, and When reconfiguring the tag cloud and accepting a request for shortening the character string length of the tag cloud, A tag cloud reconstruction step of reconstructing the tag cloud from grayed cloud database reads tag of the predetermined character string shorter string length than length, makes the tag cloud page update transmitting means, said tag cloud reconstruction A tag cloud page update transmission step of transmitting a tag cloud page including the tag cloud configured in the step to the terminal.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[overall structure]
FIG. 1 is a diagram illustrating an overall configuration for explaining a tag cloud configuration device 1 according to the present embodiment. Here, the “tag” refers to a character string that classifies the linked document (Web page). Specifically, for example, a feature word, a phrase, or the like included in the link destination document (Web page) is included, and in the present embodiment, includes a phrase that includes a plurality of phrases. “Tag cloud” refers to a plurality of tags represented in a predetermined area such as a display screen. More specifically, for example, a plurality of tags are displayed on a display screen of a Web page including hyperlinks to linked documents (Web pages) indicated by the tags. The tag cloud configuration device 1 includes a control unit 10 and a storage unit 20. The control unit 10 is a part that comprehensively controls each function related to the tag cloud configuration device 1, and includes a tag cloud page transmission request reception unit 11, a tag cloud configuration unit 12, a tag cloud page transmission unit 13, a tag cloud decompression / A shortening request reception unit 14, a tag cloud reconfiguration unit 15, and a tag cloud page update transmission unit 16 are provided. On the other hand, the storage unit 20 is a part that stores various programs (not shown) and a database for causing the tag cloud configuration device 1 to function, and includes a tag cloud database 21.

  First, the tag cloud database 21 will be described. In the tag cloud database 21, tags having different character string lengths are stored in association with the URL of the link destination document. The tag cloud database 21 is exemplified in FIG. 2, and a “tag” field indicating a tag that associates the keyword transmitted from the terminal 2 connected to the tag cloud constituent device 1 via the communication network and the URL of the linked document. And a “URL of linked document” field indicating the URL of the linked document associated with this tag.

  First, the tag cloud database 21 will be described. In the tag cloud database 21, tags having different character string lengths are stored in association with the URL of the link destination document. The tag cloud database 21 is exemplified in FIG. 2, and a “tag” field indicating a tag that associates the keyword transmitted from the terminal 2 connected to the tag cloud constituent device 1 via the communication network and the URL of the linked document. And a “URL of linked document” field indicating the URL of the linked document associated with this tag.

  For example, if the tag is “Johnny Office” and the URL of the linked document associated with this tag is “http: // aaa ...”, the “Tag” field contains “Johnny Office”. Is stored, and “http: // aaa ...” is stored in the “URL of linked document” field. In the example of FIG. 2, for example, 23 records of “Johnny office” and 11 records of “Person of Johnny office appear” are stored as tags.

  FIG. 3 is a diagram illustrating a generation example of the tag cloud database 21 according to the present embodiment. The tag cloud database 21 is generated as follows. For example, as described in International Publication No. 2002/044946, a traveling robot called a crawler collects Web pages stored in any Web server in the world. And the control part 10 divides the sentence contained in the collect | recovered Web page for every word and clause, and is directed toward the back from the sentence head (namely, head part of a joint clause) of the part which becomes "a joint clause + noun". In addition, a tag is extracted for each fixed clause from the end of the sentence (that is, the “noun” portion of “joint clause + noun”) toward the front. Further, the control unit 10 extracts the URL of the collected web page.

  For example, a web page collected by the crawler includes a sentence “Why is the movie of a person from Johnny's office singing the theme song of the person or group in which the person appears?” It is assumed that it is “http: // aaa ...”. First, the control unit 10 divides this sentence into words and clauses. Then, the sentence reads, “Johnny Office /// People / Perform [Continuous Section] / Movies / [Theme C] / Why / That / Perform / [Continuous Section] / Person / Ya / Group / ”/ Theme song / song [single clause noun] / no / is / ka /?”. Then, the control unit 10 moves backward from the noun at the beginning of the part that is “linkage clause + noun” (that is, the noun at the beginning of the linkage clause), and at the end of the part (that is, “linkage clause + noun”). The tag is extracted for each fixed section from the “noun” portion of the “noun” to the front. In this example, the parts that are “joint clause + noun” are “Johnny office /// person / man / appearing + movie” and “why / that / appearing / performing + person / ya / group”. It is. Therefore, the control unit 10 extracts “Johnny office” and “appearance”, which are nouns at the beginning of the part “community clause + noun”, as tags, and from these “Johnny office” and “appearance” A tag is extracted for each fixed section in the backward direction. Here, the control unit 10 starts with “Johnny office” as a starting point, and extracts a tag “a person from Johnny office appears” and a tag “a movie in which a person from Johnny office appears”. In addition, the control unit 10 starts with “appearance” as a starting point, extracts a tag “performs”, a tag “performers and groups”, and a tag “performers and groups sing the theme song”. To do. And the control part 10 extracts a tag for every fixed clause toward the front from the "movie" and the "person or group" which are the sentence ends of the part which becomes "continuous clause + noun". Here, the control unit 10 extracts the tag “movie in which a person from Johnny's office appears” starting from “movie”. In addition, the control unit 10 extracts a tag “performing person or group” starting from “person or group”.

  Thereafter, the control unit 10 stores the plurality of extracted tags in the “tag” field of the tag cloud database 21, and “http: // aaa ...” that is the URL of the link destination document associated with the plurality of tags. Is stored in the “URL of linked document” field of the tag cloud database 21, thereby generating the tag cloud database 21.

  Returning to FIG. 1, each component included in the control unit 10 will be described. The tag cloud page transmission request receiving unit 11 receives a tag cloud page transmission request from a terminal 2 that can be connected to the tag cloud constituent device 1 via a communication network. The tag cloud page transmission request receiving unit 11 functions as a tag cloud page transmission request receiving unit.

  The tag cloud configuration unit 12 reads the tag from the tag cloud database 21 in response to the tag cloud page transmission request reception unit 11 receiving the tag cloud page transmission request, and the number of URLs of the associated linked documents A tag cloud is configured with tags having a predetermined character string length using larger characters as the number of characters increases. The tag cloud configuration unit 12 functions as a tag cloud configuration unit. Here, the “predetermined character string length” may be any method as long as it is a predetermined character string length. For example, the “predetermined character string length” may be determined by the number of characters such as 10 characters or less. It may be determined by the number of phrases, such as a phrase.

  The case where the tag cloud page transmission request receiving unit 11 receives a tag cloud page transmission request related to “Johnny Office” will be described with reference to FIG. 2 as an example. In response to the tag cloud page transmission request receiving unit 11 receiving a tag cloud page transmission request, the tag cloud configuration unit 12 receives the tags “Johnny Office” and “Johnny Office” from the tag cloud database 21 shown in FIG. ”,“ Movies featuring people from Johnny's office ”, etc., and using larger characters as the number of linked document URLs increases, A tag cloud is configured for “Johnny office” and “movie” which are tags having a predetermined character string length. In this case, the number of URLs of linked documents associated with the tag “Johnny Office” is 23, and the number of URLs of linked documents associated with the tag “movie” is 22, so the tag “Johnny Office” The character “where” is larger than the tag “movie”.

  The tag cloud page transmission unit 13 transmits a tag cloud page including the tag cloud configured by the tag cloud configuration unit 12 to the terminal 2. The tag cloud page transmission unit 13 functions as a tag cloud page transmission unit.

  The tag cloud decompression / abbreviation request accepting unit 14 accepts a tag cloud character string length decompression / abbreviation request from the terminal 2. The tag cloud decompression / shortening request receiving unit 14 functions as a tag cloud decompression / shortening request receiving unit.

  When the tag cloud reconstruction unit 15 receives a request to expand the character string length of the tag cloud, the tag cloud reconstruction unit 15 reads a tag having a character string length longer than a predetermined character string length from the tag cloud database 21 and reconfigures the tag cloud. . On the other hand, when the tag cloud reconstruction unit 15 receives a request for shortening the character string length of the tag cloud, the tag cloud reconstruction unit 15 reads out a tag having a character string length shorter than the predetermined character string length from the tag cloud database 21 and reconfigures the tag cloud. Configure. The tag cloud reconstruction unit 15 functions as a tag cloud reconstruction unit. Here, the “character string length longer than the predetermined character string length” may be determined in any way as long as it is a predetermined character string length longer than the character string length before reconstruction. If the character string length before reconstruction is within 10 characters, for example, it can be considered to be within 20 characters, and if the character string length before reconstruction is 1 clause, it can be considered to be 2 clauses. . The “character string length shorter than the predetermined character string length” may be determined in any way as long as it is a predetermined character string length shorter than the character string length before reconstruction. If the character string length before composition is 20 characters or less, for example, it can be considered to be 10 characters or less, and if the character string length before reconstruction is 2 clauses, it can be considered to be 1 clause.

  The tag cloud can be reconfigured multiple times. For example, a tag cloud character string length extension request can be made more than once, or a tag cloud character string length extension request can be made once and then a tag cloud character string length extension request can be made. it can.

  The case where the tag cloud decompression / abbreviation request receiving unit 14 receives a tag cloud character string length decompression request will be described using FIG. 2 as an example. The tag cloud reconstruction unit 15 is a tag of a character string length (for example, two phrases) longer than a predetermined character string length (for example, one phrase) from the tag cloud database 21 shown in FIG. ”,“ I love Johnny's office ”,“ Movies that people from Johnny's office appear ”and“ Movies that resonate with Zune ”are tags already formed by the tag cloud component 12 "Johnny office people appear", "Johnny office favorite", "Johnny office people", tags newly read by the tag cloud reconstruction unit 15 in "Johnny office" and "movie" Will be reconfigured with the addition of “movies that will appear” and “movies that resonate with Zune”.

  Here, the tag cloud reconstruction unit 15 associates the decompressed / shortened tag character string with a different number of URLs of linked documents from the decompressed / shortened tag character strings in the reconfigured tag cloud. If the character string is stored in the tag cloud database 21, the tag cloud is reconfigured using a larger character as the character string has a larger number of URLs of the link destination document.

  For example, in the example shown in FIG. 2, the character string “Johnny office person appears”, which is one of the expanded / shortened tags, is another favorite tag of “Johnny office” ”And the URLs of the linked documents of a different number and stored in the tag cloud database 21. In this case, the tag cloud reconfiguration unit 15 uses a character string larger in the character string (in the example of FIG. 2, “Johnny office person appears”) having a larger number of URLs of the linked document, Reconfigure.

  At that time, the tag cloud reconstructing unit 15 determines that the same part of the character strings of the plurality of tags that have been expanded / shortened are the same for the tag cloud after the reconstruction. The tag cloud is reconfigured by sharing and arranging character strings of parts other than the part of the same character string before or after that.

  For example, in the example shown in FIG. 2, with regard to the tag cloud after reconfiguration, some of the expanded and shortened tags “persons of Johnny office appear” and “loved Johnny office” The character strings (“Johnny office” in the example of FIG. 2) are the same. In this case, the tag cloud reconstruction unit 15 shares “Johnny Office”, which is a part of the same character string, and before or after that part of the character string other than the part of the same character string ( In the example of FIG. 2, the tag cloud is reconfigured by arranging “No people appear” and “I like”.

  Returning to FIG. 1, the tag cloud page update transmission unit 16 transmits a tag cloud page including the tag cloud configured by the tag cloud reconfiguration unit 15 to the terminal 2. The tag cloud page update transmission unit 16 functions as a tag cloud page update transmission unit.

  As shown in FIG. 1, the terminal 2 includes a control unit 30, and the control unit 30 makes a tag cloud page transmission request to the tag cloud configuration device 1 in response to a user's request operation. The tag cloud page display control unit 32 that receives the tag cloud page transmitted by the page transmission request unit 31 and the tag cloud page transmission unit 13 and performs control to display the received tag cloud page on the tag cloud page display unit 41. And a tag cloud decompression / abbreviation requesting unit 33 for requesting the tag cloud constituent device 1 to decompress / shorten the character string length of the tag cloud in response to a user's requested operation.

In the example of FIG. 7, when the user places the cursor 42 on the tag cloud decompression request operation unit 43 a and clicks a mouse (not shown), the tag cloud decompression / abbreviation request unit 33 sends a tag to the tag cloud constituent device 1. A request for expansion of the character string length of the cloud is made, and the tag cloud expansion / contraction request receiving unit 14 receives an expansion request of the character string length of the tag cloud. At this time, the tag cloud reconstruction unit 15 selects “Johnny office work” from the tag cloud database 21 shown in FIG. 2 as a tag having a character string length (for example, two phrases) longer than a predetermined character string length (for example, one phrase). The tag cloud that the tag cloud component 12 has already constructed, reads out “Persons in the office”, “I love Johnny's office”, “Movies in which Johnny ’s office” and “Movies that resonate with Zune” "Johnny office" and "movie" are tags newly read by the tag cloud reconstruction unit 15 "Johnny office people appear", "Johnny office loves", "Johnny office The tag cloud is reconfigured with the addition of “movies of people in the place” and “movies that resonate with Zune”.

  By the way, one of the expanded tags, “Johnny office people appear”, has a different number of linked documents than the other expanded tags, “My favorite Johnny offices”. And is stored in the tag cloud database 21 in association with the URL. In this case, the tag cloud reconfiguration unit 15 reconfigures the tag cloud using characters that are larger as the character string has a larger number of URLs of the linked document. In addition, regarding the tag cloud after the reconstruction, a part of the strings (“Johnny office people appear” and “Johnny office favorite”, which are expanded plural tags (in this example, “Johnny office loves”). "Office") is the same. In this case, the tag cloud reconstruction unit 15 shares “Johnny Office”, which is a part of the same character string, and then a character string of a part other than the part of the same character string (this example Then, arrange "the person who appears" and "I love you") to reconfigure the tag cloud.

  When the tag cloud reconfiguration is finished, the tag cloud page update transmission unit 16 transmits the tag cloud page including the tag cloud configured by the tag cloud reconfiguration unit 15 to the terminal 2, and the tag cloud page display control unit 32 The tag cloud page is received, and the received tag cloud page is controlled to be displayed on the tag cloud page display unit 41.

  FIG. 7 is a display example on the tag cloud page display unit 41 at this time. In the tag cloud page display section 41, the tag “Johnny office” before the reconstruction is expanded and reconstructed, the tag “person of Johnny office appears” and “I love Johnny office” A tag cloud page that includes a tag, a tag "movie that Johnny office person appears", and a tag "movie that resonates with Zune", which is an expanded and reconstructed tag "movie" before reconstruction Are displayed together with the number of URLs of linked documents associated with these tags.

  At that time, the number of URLs of linked documents associated with the character string “One of Johnny's people will appear”, which is one of the expanded tags, is the same as the other expanded tags, “I love Johnny's office. Because the number of URLs of linked documents associated with the character string “NA” is larger, the character “Johnny office person appears” is larger than the character “I love Johnny office” . Also, the same character string (in this example, “Johnny Office”) that forms part of the expanded tags “Persons of Johnny Office” and “I Love Johnny Office” After that, character strings of parts other than the part of the same character string (in this example, “the person appears” and “I love”) are arranged. The same applies to the tag “movies featuring people from Johnny's office” and the tag “movies that resonate with Zune”.

  In the tag cloud decompression request operation unit 43a, since the character “+” is displayed in a circle, the user moves the cursor 42 to the tag cloud decompression request operation unit 43a and moves the mouse (not shown). By clicking, it is possible to perform an operation to request expansion of the tag cloud character string length. In the tag cloud shortening request operation unit 43b, since the character “-” is displayed in the circle, the user moves the cursor 42 to the tag cloud shortening request operation unit 43b and moves the mouse (not shown). By clicking, it is possible to perform a request operation for shortening the character string length of the tag cloud.

  Next, FIG. 9 will be described. FIG. 9 shows that in the example of FIG. 8, when the user places the cursor 42 on the tag cloud decompression request operation unit 43a and clicks the mouse (not shown), the tag cloud decompression / abbreviation request unit 33 becomes the tag cloud constituent device. When the tag cloud character string length expansion request is sent to 1 and the tag cloud expansion / reduction request receiving unit 14 receives the tag cloud character string length expansion request, an example of display on the tag cloud page display unit 41 Show.

  In the tag cloud page display unit 41, a tag “a movie in which a person from Johnny's office appears” is reconstructed by extending the tag “a person from Johnny's office will appear” before reconstruction, and “ The tag "Rumor that a person from Johnny's office will appear" and the tag "I love Johnny's office" before the reorganization were expanded and restructured, "Recommended for those who love Johnny's office" And the tag “I love Johnny's office”, the tag “The movie in which Johnny ’s office appeared” before the reconstruction, and the tag “The movie that resonates with Zune” before the reconstruction A tag cloud that includes the tag "movies that resonate with Zune after watching", "movies that resonate with Zune from beginning to end", and "movie that resonates with Zune from the middle" This is the page It is displayed with the number of URL of the associated destination document tags.

  According to the present embodiment, the tag cloud decompression / reduction request accepting unit 14 accepts a tag cloud character string length decompression / reduction request from the terminal 2. When the tag cloud reconstruction unit 15 receives a request to expand the character string length of the tag cloud, the tag cloud reconstruction unit 15 reads out a tag having a character string length longer than the predetermined character string length from the tag cloud database and reconfigures the tag cloud. To do. On the other hand, when a request for shortening the character string length of the tag cloud is received, a tag having a character string length shorter than a predetermined character string length is read from the tag cloud database to reconfigure the tag cloud.

  As a result, when the meaning of the tag displayed on the terminal 2 is simple and too wide, or when it can have a plurality of meanings, the user makes a request to expand the character string length of the tag cloud from the terminal 2. Since the tag image is determined by visually recognizing the tag cloud having a longer character string length, it is possible to easily find a desired web page as compared with the conventional search system, and as a result, find the desired web page. Can be suppressed. Conversely, if the tag character string displayed on the terminal is too long, the number of tags that can be displayed in a finite display space is limited, or if the user does not know which tag to select, By making a request for shortening the character string length of the tag cloud from the terminal 2, it is possible to display more tags using a vacant display space and to acquire information about tags widely. Therefore, it is possible to provide a tag cloud configuration device 1 that can more easily use a search system that uses a tag cloud and can further reduce the time until a desired Web page is found, and that can expand and contract a character string length.

  Further, according to the present embodiment, the tag cloud reconstruction unit 15 has a different number of linked documents in which the character string of the part of the expanded / shortened tag is different from the character string of the other part of the reconstructed tag cloud. When the URL is stored in the tag cloud database 21 in association with the URL, the tag cloud is reconfigured using a larger character as the character string of the portion where the number of URLs of the linked document is larger.

  As a result, the tag cloud constituent device 1 stores a part of the character string of the expanded / shortened tag in the tag cloud database 21 in association with the number of URLs of the linked documents different from the character strings of the other parts. In this case, in the same tag, the difference in the number of linked documents in the character string of each part can be expressed by the difference in character size. As a result, the user can easily grasp the difference in the number of linked documents depending on the size of the character used in the character string of each part of the tag, which makes it easier to use the search system using the tag cloud, It is possible to provide a tag cloud constituent device 1 that can further suppress the time until a desired Web page is found and that can expand and contract the character string length.

  Furthermore, according to the present embodiment, the tag cloud reconfiguration unit 15 determines the same one when the character strings of a plurality of tags that have been expanded / shortened are the same for the tag cloud after the reconfiguration. A part of the character string is shared, and a part of the character string other than the part of the same character string is arranged before or after that part to reconfigure the tag cloud.

  Thereby, when a part of character strings of a plurality of tags are the same, the tag cloud constituent device 1 shares the same part of the character string, and before or after that part of the character string Can be used to configure a tag cloud. Accordingly, the user can visually recognize the same partial character string and a plurality of other character strings as a series of character strings. Therefore, the user can more easily use a search system using a tag cloud by visually recognizing a plurality of tags including a part of the same character string as a series of character strings, and find a desired Web page. It is possible to provide a tag cloud constituent device 1 that can further suppress the time and can expand and contract the character string length. Further, by forming a tag cloud by sharing a part of the same character string, it is possible to save space and display many tags in a limited display space.

  In addition, the effect described in this embodiment only enumerated the most suitable effect which arises from this invention, and the effect by this invention is not limited to what was described in this embodiment.
