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

  In FIG. 6, when starting the process, the multiple product name database registration unit 32 of the product search server 3 acquires query log data from the query log 301 by the query log acquisition unit 321 (step S101).

  Next, the multiple product name database registration unit 32 extracts and specifies multiple product names from the acquired query log data by the multiple product name extraction unit 322 (step S102). Details of processing in the multiple product name extraction unit 322 will be described later.

  Next, the multiple product name database registration unit 32 registers the specified multiple product names in the multiple product name database 302 by the database registration unit 323 (step S103).

  FIG. 7 is a flowchart illustrating a processing example of the multiple product name extraction unit 322.

  In FIG. 7, the multiple product name extraction unit 322 performs the following processing for each acquired query log data.

  First, when the process starts (step S201), the multiple product name extraction unit 322 determines whether the query log data search expression is an OR search or a NOT search (step S202). If an OR operator is included in the search expression, an OR search is performed, and if a NOT operator is included, a NOT search is performed.

  If the query log data search expression is an OR search or a NOT search (Yes in step S202), the multiple product name extraction unit 322 specifies the search terms before and after the OR operator or the NOT operator as multiple product names ( Step S203), the process is terminated (Step S206). In order to improve the accuracy of multiple product names, the multiple product names may be specified only when it is confirmed by a synonym dictionary (not shown) that multiple search terms are included in the synonyms. . Furthermore, the number of times specified as a plurality of product names may be counted, and only when a predetermined number of times has been reached, may be formally specified as a plurality of product names.

  When the query log data search expression is an OR search or not a NOT search (No in step S202), the multiple product name extraction unit 322 further determines whether there is a query within a predetermined time with the same session ID (step S204). ).

  When there is a query within a certain time with the same session ID (Yes in step S204), the search term of each query is specified as a plurality of product names (step S205), and the process is terminated (step S206). In order to improve the accuracy of multiple product names, the multiple product names may be specified only when it is confirmed by a synonym dictionary (not shown) that multiple search terms are included in the synonyms. . Furthermore, the number of times specified as a plurality of product names may be counted, and only when a predetermined number of times has been reached, may be formally specified as a plurality of product names.

  If there is no query within the predetermined time with the same session ID (No in step S204), the processing is terminated as it is (step S206).

  By the above processing, for example, when query log data “heating OR heater” exists, “heating” and “heater” are registered in the multiple product name database 302 as multiple product names “heating, heater”. This is because the user who has issued the search request can determine that both “heating” and “heater” are aware of the product names in the same row.

  For example, when query log data “heating NOT stove” exists, “heating” and “stove” are registered in the multiple product name database 302 as multiple product names “heating, stove”. This is because the user who has issued the search request can determine that “heating” and “stove” are conscious of the product names in the same row by excluding “stove”.

  Also, for example, when query log data of “jewelry” and “accessories” exist within a certain time with the same session ID, these “jewelry” and “accessories” are multiple product name databases as multiple product names “jewelry and accessories”. 302 is registered. This is because the user who issued the search request can determine that both “jewelry” and “accessory” have been input continuously in order to search for the same product, and can be determined to be aware of the same product name. It is.

  Returning to FIG. 6, when the user of the user terminal 2 searches for a product for purchasing a product, the browser 21 of the user terminal 2 accesses the product search processing unit 31 of the product search server 3 to make a search page request (step) S111). For the page request, a message including a GET method according to HTTP, which is an Internet standard protocol, a request URI (Uniform Resource Indicator), and the like is transmitted from the browser 21 of the user terminal 2 to the product search processing unit 31 of the product search server 3. This is done.

  In response to this, the product search processing unit 31 of the product search server 3 returns the page data of the search page stored or dynamically generated by the search request receiving unit 311 to the browser 21 of the user terminal 2 (step S112). ). The page data is described in HTML or the like, and is transmitted from the product search processing unit 31 of the product search server 3 to the browser 21 of the user terminal 2 according to an HTTP response or the like.

  The browser 21 of the user terminal 2 displays a search page (step S113), and the user inputs search conditions (step S114). FIG. 8 is a diagram showing a screen example of a search page, which is provided with a search condition input field and a “search” button. The user inputs characters and numbers in the input field by keyboard operation or the like and presses the “search” button to complete the input.

  Returning to FIG. 6, when the input to the search page is completed, the input content (search request) of the search condition is transmitted from the browser 21 of the user terminal 2 to the product search processing unit 31 of the product search server 3 (step S115). The input content is transmitted from the browser 21 of the user terminal 2 to the product search processing unit 31 of the product search server 3 as data such as HTML added to the HTTP POST method or PUT method, or as a parameter added to the GET method. .

  The product search processing unit 31 of the product search server 3 that has received the search request records the search condition included in the search request by the search request receiving unit 311 in the query log 301 in association with the received date and session ID (step S116). ).

  Next, the product search processing unit 31 of the product search server 3 uses the other product name acquisition unit 312 to search the multiple product name database 302 for multiple product names including the search term based on the search terms included in the received search condition. Then, other product name (s) registered as a pair with the search term are acquired (step S117).

  Next, the product search processing unit 31 of the product search server 3 corrects the search condition by the search condition correction unit 313 (step S118).

  There are two methods for correcting the search condition by the search condition correction unit 313. One is to automatically add another product name acquired by the other product name acquisition unit 312 to the search condition designated by the user as an OR search without asking the user for confirmation. The other is to display a suggestion to the user that the search condition should be corrected, and add another product name as an OR search when the user confirms. FIG. 9 is a diagram showing an example of a suggestion on the search screen. “Since there is another product name △△△△ in the product name XXXXX included in the search expression you entered, It is recommended that you search. The message “The search condition is corrected by pressing the confirmation button.” Is displayed, and the search condition is corrected by pressing the “Confirm” button. When the “ignore” button is pressed, the search condition is not corrected.

  Returning to FIG. 6, after correcting the search conditions, the product search processing unit 31 of the product search server 3 searches the product database 303 based on the search conditions by the search execution unit 314 (step S <b> 119). That is, a record that matches (including a partial match) is obtained by comparing a character / numeric string other than the search condition operator and an item such as “keyword” in the product database 303 (FIG. 4), and the operator is taken into consideration. Then, a logical operation is performed to obtain a search result.

  Next, the product search processing unit 31 of the product search server 3 uses the search result page generation unit 315 to generate a search result page (step S120). That is, a list page of products hit by the search is generated.

  Next, the product search processing unit 31 of the product search server 3 transmits the search result page to the browser 21 of the user terminal 2 through the search result page transmission unit 316 (step S121). The page data is transmitted from the product search processing unit 31 of the product search server 3 to the browser 21 of the user terminal 2 according to an HTTP response or the like.

  The browser 21 of the user terminal 2 displays the received search result page (step S122). FIG. 10 is a diagram showing a screen example of the search result page, in which titles, descriptions, images, and the like of a plurality of products hit by the search are displayed.

<Summary>
As described above, according to the present embodiment, a plurality of fluid product names for the same product are automatically extracted from the query log 301 and registered in the multiple product name database 302, and a search request from a user is received. On the other hand, other product names are corrected (supplemented) from the multiple product name database 302. Therefore, even when a search request is made with a product name that is not set as a keyword in the product database 303, it is more likely that a desired product will be searched for by supplementing the product name, and the search entered by the user It is possible to perform a complete search for words.
