<Configuration>
FIG. 1 is a diagram showing a configuration example of a system according to an embodiment of the present invention.

  In FIG. 1, a network 1 such as the Internet is connected with a plurality of terminals 2 such as PCs (Personal Computers), PDAs (Portable Digital Assistants), and mobile phones operated by a user. The terminal 2 includes a general browser 21 (Web browser) 21. The browser 21 performs request / acquisition / display of page data described in a language such as HTML (Hyper Text Markup Language), transmission of form data, and the like according to HTTP (Hyper Text Transfer Protocol) which is a standard protocol of the Internet. It has a function.

  On the other hand, a category presentation device 3 that provides a search service in response to a search request from the browser 21 of the terminal 2 operated by the user is connected to the network 1.

  The category presenting device 3 includes, as function units, a search reception unit (query input word acquisition unit) 31, a query input word content category acquisition unit 32, a user behavior deviation value acquisition unit 33, a category specification unit 34, and a UGC information acquisition unit 35. A UGC information output unit 36, a Web information search unit 37, a Web information output unit 38, and a page composition unit 39 are provided. These functional units are realized by a computer program executed on hardware resources such as a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory) of a computer constituting the category presentation device 3. Is. These functional units do not need to be arranged on a single computer, and may be distributed as necessary.

  In addition, a UGC information database 41, a user behavior deviation value database (user behavior index database) 42, and a Web information database 43 are provided as databases referred to by the category presentation device 3. These databases systematically hold predetermined data on a storage medium such as an HDD (Hard Disk Drive) in a computer that holds each database.

  The search reception unit 31 provides a search page to the browser 21 of the terminal 2 and acquires a search word (query input word) input to the search page to obtain a query input word containing category acquisition unit 32 and It has a function of handing over to the Web information search unit 37.

  The query input word content category acquisition unit 32 searches the UGC information database 41 based on the query input word acquired from the search reception unit 31, and acquires the query input word content category (s) of the article including the query input word. The query input word containing category list has a function of handing over to the user action deviation value acquisition unit 33 in the next stage together with the query input word. The UGC information is content written by a general user (UGC) such as a question and answer site, a blog, or a bulletin board. Note that UGC information is once collected (crawled) in the UGC information database 41 for reasons such as speeding up of the search, and this UGC information database 41 is searched. You may make it search directly.

  The user behavior deviation value acquisition unit 33 searches the user behavior deviation value database 42 based on the query input word content category list acquired from the query input word content category acquisition unit 32, and each query included in the query input word content category list A user behavior deviation value corresponding to the input word content category is acquired, associated with each query input word content category, and delivered to the next category specifying unit 34 together with the query input word. The user behavior deviation value is a predetermined value of the total number of articles viewed (PV (Page View) value) included in each query input word-containing category (a value obtained by adding the number of times viewed for all contents included in the category). The deviation value of the latest time zone with respect to the average value (user action average value) within the period is used as an index indicating the degree of excitement of the topic. It should be noted that other acquirable values (user behavior data) such as the number of writings may be used instead of, or in addition to, the number of article browsing (PV value) that is the basis for calculating the user behavior deviation value. Furthermore, instead of the user behavior deviation value, another index indicating the excitement of the user's browsing behavior may be used. An index indicating the excitement of the user's browsing behavior including the user behavior deviation value is set as a user behavior index.

  The category specifying unit 34 specifies a query input word containing category having the largest user action deviation value from a plurality of query input word containing categories and user action deviation value pairs acquired from the user action deviation value acquiring unit 33, and inputs a query. It has the function of handing over to the UGC information acquisition part 35 of the next stage with a word. Note that the comparison of user behavior deviation values is performed by first focusing on the lowest category of the query input word-containing category. If there is no difference in user behavior deviation values, query input is performed by focusing on the user behavior deviation values of the higher categories. Identify word inclusion categories.

  The UGC information acquisition unit 35 acquires the article content including the query input word from the UGC information database 41 based on the query input word-containing category and the query input word acquired from the category specifying unit 34, and the article content is included in the query input word-containing It has the function of handing over to the UGC information output part 36 of the next stage as UGC information with a category. Note that when the UGC information database 41 is searched by the query input word content category acquisition unit 32, the article content is also acquired, and the UGC information acquisition unit 35 is obtained via the user behavior deviation value acquisition unit 33 and the category specification unit 34. The search of the UGC information database 41 in the UGC information acquisition unit 35 can be omitted. In this case, the UGC information acquisition unit 35 is a process that only selects the article content corresponding to the query input word-containing category specified by the category specifying unit 34.

  The UGC information output unit 36 has a function of generating partial screen data of the UGC search result from the query input word content category and the article content acquired from the UGC information acquisition unit 35 and delivering the partial screen data to the next page composition unit 39. ing.

  The Web information search unit 37 searches the Web information database 43 based on the query input word acquired from the search reception unit 31, and uses the part of the article contents including the query input word and the article URL as Web information as the next Web information. It has a function of handing over to the output unit 38. Here, the contents of the Web information are article contents widely published on sites operated by companies, organizations, individuals, and the like. Note that web information is once collected (crawled) in the web information database 43 for reasons such as speeding up the search, and the web information database 43 is searched. However, the target site is searched directly. May be.

  The Web information output unit 38 has a function of generating partial screen data as a Web search result from the Web information acquired from the Web information search unit 37 and delivering the partial screen data to the next page composition unit 39.

  The page composition unit 39 synthesizes the partial screen data of the UGC search result acquired from the UGC information output unit 36 and the partial screen data of the Web search result acquired from the Web information output unit 38, and sends it to the browser 21 of the terminal 2. It has a function to transmit as a search result.

  FIG. 2 is a diagram illustrating a hardware configuration example of the category presentation device 3.

  In FIG. 2, the category presentation device 3 is connected to a CPU 302, ROM 303, RAM 304, NVRAM (Non-Volatile Random Access Memory) 305, I / F (Interface) 306, and I / F 306 connected to a system bus 301. , A keyboard, a mouse, a monitor, an I / O (Input / Output Device) 307 such as a CD / DVD (Compact Disk / Digital Versatile Disk) drive, an HDD 308, a NIC (Network Interface Card) 309, and the like. M is a medium (recording medium) such as a CD / DVD in which a program or data is stored.

  FIG. 3 is a diagram showing an example of the data structure of the UGC information database 41. FIG. 3A shows an example of the data structure of the UGC information database 41. Items such as “category”, “article number”, “publication date / time”, “publisher”, “article URL”, “article content”, and “extraction term” are displayed. Have.

  The “category” has a hierarchical structure as shown in FIG. 3B, and a category is assigned when an article is written on a question and answer site, a blog, a bulletin board, or the like. Although the lowest category in FIG. 3B is often assigned, a higher category may be assigned in some cases.

  The “article number” is a symbol that identifies an article in the UGC information database 41. “Date and time” is the date and time when the article was written and published. “Publisher” is a symbol that identifies the user who published the article. “Article URL” is the address (URL: Uniform Resource Locator) of the site where the article is posted. “Article content” is the title and text content of the article. The “extraction term” is a keyword extracted for article content search.

  FIG. 4 is a diagram showing an example of the data structure of the user behavior deviation value database 42. FIG. 4A shows an example of the data structure of the user behavior deviation value database 42, and has items such as “category”, “user behavior deviation value”, and “user behavior average value”.

  “Category” is a category of each hierarchy shown in FIG. Entries are provided not only for the lowest category but also for the higher category.

  As described above, the “user behavior deviation value” is a deviation value in the latest time zone with respect to an average value (user behavior average value) within a predetermined period of the number of browsing (PV value) of articles included in each category. The “user behavior average value” is an average value within the predetermined period. The number of article browsing (PV value) is acquired from a target question-and-answer site, a blog, a bulletin board or the like, or a server or the like that monitors those sites.

  FIG. 4B shows an example of the temporal change of the PV value for articles included in a certain category, and the PV value in a period retroactive by a predetermined period (several days, weeks, months, etc.) from the present time. The deviation value of the PV value in the current time zone (several hours, etc.) with respect to the average value is the user behavior deviation value. Therefore, even if the site is popular and the PV value is always high, the user behavior deviation value does not increase unless the PV value changes greatly. On the contrary, even if the site has a low PV value, the user behavior deviation value becomes high if there is a large change in the PV value.

  FIG. 5 is a diagram showing an example of the data structure of the Web information database 43, and has items such as “article URL”, “article content”, and “extraction term”.

  “Article URL” is the address (URL) of the site where the article is posted. “Article content” is the title and text content of the article. The “extraction term” is a keyword extracted for article content search.

<Operation>
FIG. 6 is a sequence diagram showing a processing example of the above embodiment.

  In FIG. 6, a user who wants to obtain desired information requests a search page from the browser 21 of the terminal 2 to the search reception unit 31 of the category presentation device 3 (step S101). When the top page of the portal site also serves as the search page, the search page request means access to the top page. The request for the search page is transmitted from the browser 21 of the terminal 2 to the search reception unit 31 of the category presentation device 3 including a GET method according to HTTP, which is a standard protocol of the Internet, and a request URI (Uniform Resource Indicator). This is done.

  The search reception unit 31 of the category presentation device 3 that has received the request for the search page internally stores the search page data or the search page data that is dynamically generated according to a predetermined algorithm. 2 as a response (step S102). The search page is described in HTML or the like, and is transmitted from the search reception unit 31 of the category presentation device 3 to the browser 21 of the terminal 2 according to an HTTP response or the like.

  The browser 21 of the terminal 2 that has received the search page data displays the search page (step S103). FIG. 7A is a diagram showing a screen example of a search page, which is provided with an input field 201 for inputting a search word and a search button 202 for instructing a search after inputting the search word.

  Returning to FIG. 6, the user inputs a search word in the input field of the search page in the browser 21 of the terminal 2 and presses the search button to complete the input (step S104). FIG. 7B shows a state where the search word “XXX” has been entered in the input field 201. Here, it is assumed that the search word “XXX” is a combination name of a comedian.

  Returning to FIG. 6, when the input to the search page is completed, the browser 21 of the terminal 2 transmits a query including the search word to the search reception unit 31 of the category presentation device 3 (step S105). This query is transmitted from the browser 21 of the terminal 2 to the search reception unit 31 of the category presentation device 3 as data such as HTML added to the HTTP POST method or PUT method.

  The search reception unit 31 of the category presenting apparatus 3 that has received the query extracts a search word (query input word) from the query and delivers it to the query input word-containing category acquisition unit 32 (step S106). The information is transferred to the information search unit 37 (step S107). Since the data delivery is communication within the category presentation device 3, it can be in any format.

  The query input word containing category acquisition unit 32 that has received the query input word from the search receiving unit 31 searches the UGC information database 41 based on the query input word (step S108), and includes the query input word of articles including the query input word. The category (s) is acquired to obtain a query input word containing category list, and is delivered to the user action deviation value acquisition unit 33 in the next stage together with the query input word (step S109). Since the data delivery is communication within the category presentation device 3, it can be in any format.

  That is, the query input word content category acquisition unit 32 searches the article contents or extracted terms in the UGC information database 41 shown in FIG. 3A using the query input word as a key, and lists hit record categories. Query input word containing category list. FIG. 8A shows an example of a query input word-containing category list. From a search word “XXX” that is a combination name of a comedy entertainer, a query input word-containing category list “Entertainment> Comedy> Entertainer ( Male) ”,“ Entertainment> Comedy> Production ”,“ Entertainment> Sports> Sumo ”. The reason that “entertainment> sports> sumo” is included is that the search word “XXX” also exists in sumo terms.

  Returning to FIG. 6, the user behavior deviation value acquisition unit 33 that has received the query input word content category list and the query input word from the query input word content category acquisition unit 32 performs the user behavior deviation value database based on the query input word content category list. 42 is searched (step S110), the user behavior deviation value corresponding to each query input word content category included in the query input word content category list is acquired, and associated with each query input word content category, and the query input word and the next It is handed over to the category identifying unit 34 of the stage (step S111). Since the data delivery is communication within the category presentation device 3, it can be in any format.

  In other words, the user behavior deviation value acquisition unit 33, for each query input word content category included in the query input word content category list, corresponds to the user corresponding to the category in the user behavior deviation value database 42 shown in FIG. The behavior deviation value is acquired and associated with each query input word content category in the query input word content category list. FIG. 8B shows a state in which each query input word-containing category in the query input word-containing category list is associated with the user behavior deviation value.

  Instead of acquiring the user behavior deviation value calculated and stored in advance from the user behavior deviation value database 42, user behavior data such as the number of article browsing (PV value) and the number of writing is acquired at that time. The user behavior deviation value or the user behavior index may be calculated each time by performing arithmetic processing.

  Returning to FIG. 6, the category specifying unit 34 that receives the user action deviation value and the query input word corresponding to each query input word containing category in the query input word containing category list from the user action deviation value acquiring unit 33 receives the user action deviation value. The largest query input word content category is identified (step S112), and the identified query input word content category is delivered to the UGC information acquisition unit 35 in the next stage together with the query input word (step S113). Since the data delivery is communication within the category presentation device 3, it can be in any format.

  FIG. 8C shows the user behavior deviation value from the three query input word inclusion categories “Entertainment> Comedy> Entertainer (Male)”, “Entertainment> Comedy> Production”, “Entertainment> Sport> Sumo” in FIG. 8B. “Entertainment> Comedy> Entertainer (male)” is the largest. In this example, it is specified by the magnitude of the user behavior deviation value of the lowest category of each query input word inclusion category (the category including “entertainer (male)” if “entertainment> comedy> entertainer (male)”) However, if there is a user behavior deviation value that is the same in the lowest category, determine the magnitude of the user behavior deviation value by focusing on the upper category and keep it higher until it can be identified Go back. For example, if the user behavior deviation values of “Entertainment> Comedy> Entertainer (male)” and “Entertainment> Sports> Sumo” are the same value, the higher “Entertainment> Comedy” and “Entertainment> Sports” user behavior deviation The values will be compared. In preparation for such a case, the user behavior deviation value acquisition unit 33 acquires user behavior deviation values for the upper category as well as the lowest level, or the user behavior deviation value acquisition unit from the category identification unit 34. 33 is requested each time to acquire the user behavior deviation value of the upper category necessary for comparison.

  In addition to specifying the query input word content category having the largest user behavior deviation value, a plurality of query input word content categories having higher user behavior deviation values may be specified. In addition, when a general user behavior index is used as a reference instead of the user behavior deviation value, the user behavior index is appropriate from the viewpoint of showing that the user behavior index has become a hot topic according to the nature of the user behavior index. A query input word containing category having a value will be specified.

  Returning to FIG. 6, the UGC information acquisition unit 35 that has received the specified query input word-containing category and the query input word from the category specifying unit 34 performs a query from the UGC information database 41 within the range of the specified query input word-containing category. Article content (s) including the input word are retrieved and acquired (step S114), and the part of the article content, the article URL, and the query input word containing category are delivered to the UGC information output unit 36 in the next stage as UGC information. (Step S115). Since the data delivery is communication within the category presentation device 3, it can be in any format.

  That is, the UGC information acquisition unit 35 searches the category of the UGC information database 41 shown in FIG. 3 using the query input word content category as a key, and simultaneously uses the query input word as a key for article contents or extraction terms. The search is performed, and the article content and the article URL of the record hit by the AND condition of both are acquired.

  Returning to FIG. 6, the UGC information output unit 36 that has received the UGC information from the UGC information acquisition unit 35 receives the partial screen data (layout UGC information) of the UGC search result from the query input word content category, the article content, and the article URL. It is generated (step S116) and delivered to the next page composition unit 39 (step S117). Since the data delivery is communication within the category presentation device 3, it can be in any format.

  In other words, the UGC information output unit 36 generates partial page data by HTML or the like including a link (hot link) to the article from the query input word inclusion category, the article content, and a fixed phrase or figure as a headline. .

  On the other hand, the Web information search unit 37 that has received the query input word from the search accepting unit 31 searches the Web information database 43 based on the query input word (step S118), and a part of the article content including the query input word (first) ) And the article URL are delivered as Web information to the Web information output unit 38 at the next stage (step S119). Since the data delivery is communication within the category presentation device 3, it can be in any format.

  That is, the Web information search unit 37 searches for the article contents or extracted terms in the Web information database 43 shown in FIG. 5 using the query input word as a key, and searches for a part of the article contents of the hit record and the article URL. get.

  Returning to FIG. 6, the Web information output unit 38 that has received the Web information from the Web information search unit 37 receives partial screen data (layout search result) of the Web search result from a part of the article content of the record and the article URL. It is generated (step S120) and delivered to the next page composition unit 39 (step S121). Since the data delivery is communication within the category presentation device 3, it can be in any format.

  That is, the Web information output unit 38 generates partial page data by HTML or the like including a link (hot link) to the article from a part of the article content, the article URL, and a fixed phrase or figure that becomes a headline. .

  Then, the page composition unit 39 that has received the laid out UGC information from the UGC information output unit 36 and the laid out search result from the Web information output unit 38 synthesizes both pages (step S122), and the request source terminal The composite search result page data is transmitted to the second browser 21 (step S123). The combined search result page data is described in HTML or the like, and is transmitted from the page combining unit 39 of the category presentation device 3 to the browser 21 of the terminal 2 according to an HTTP response or the like. The browser 21 of the terminal 2 that has received the search result page data displays the composite search result page (step S124).

  FIG. 9 is a diagram showing a screen example of the combined search result page. In addition to the search word input field 211 and the search button 212 for re-searching, a Web search result display field 213 and a UGC search result display field 214 are displayed. Is provided.

  In the Web search result display column 213, article titles 215 and 216 of sites hit by the Web search are displayed.
