[Flowchart of main processing]
FIG. 3 is a flowchart of the indexing process of the search server 1 according to this embodiment. For example, the indexing process is periodically performed at a predetermined timing determined by the administrator of the search server 1.

  S1: The control unit 10 (Web page acquisition unit 11) acquires a Web page by crawling the content server 2. Then, the control unit 10 stores the acquired Web page in the collection Web page DB 26.

  S2: The control unit 10 (Web page analysis means 12) performs Web page analysis processing. Specifically, the web page analysis unit 12 analyzes the web page stored in the collection web page DB 26 and extracts the device word stored in the device determination DB 22 in association with the device information.

  S3: The control unit 10 calculates a page weight indicating the characteristics of the Web page. The page weight is, for example, the number of link data that is the number of Web pages to which the Web page is linked, and is received by a device calculated by another device (not shown) connected via the communication network 3. May be used.

  S4: The control unit 10 (applicable device determination means 13) determines device information that matches the Web page from the device word extracted in S2. The device information DB 22 is used to determine device information.

  S5: The control unit 10 (indexing storage means 14) stores the device information determined in S4 in the indexing DB 24 together with the link data of the Web page. Similarly, the control unit 10 stores the page weight calculated in S3 in the indexing DB 24 in association with the link data of the Web page.

  Thus, the search server 1 uses the device determination DB 22 that stores the device information and the device word that can identify the device in association with each other, so that the device word that includes the device that matches the Web page is included in the Web page. Can be determined.

[Device determination DB 22 and indexing DB 24]
FIG. 4 is a diagram showing a device determination DB 22 and an indexing DB 24 stored in the storage unit 20 according to the present embodiment. The device determination DB 22 is a DB used for determination by the control unit 10 to extract a device word from the Web page in S2 of FIG. 3 and to determine device information from the device word in S4 of FIG. is there. The indexing DB 24 is a database in which the control unit 10 stores device information and page weights in S5 of FIG. 3 described above.

  The device determination DB 22 shown as an example in FIG. 4A stores the device word 22a and the compatible device 22b in association with each other. The compatible device 22b stores device information that matches the device word stored in the device word 22a. Here, the device A is iPhone5. For example, iPhone 5 has a characteristic of using “iui.css” of a style sheet and “iui.js” of a script, which are dedicated libraries. Therefore, in the device word 22a, a predetermined character string related to the device included in the meta information of the Web page such as the reference file name is stored as information unique to each device.

  In addition, a character string unique to the meta information of the Web page described in cHTML (compact HTML) for displaying the Web page on the mobile phone 8 can be stored in the device word 22a. What is stored in the device word 22a may be any character string as long as it can identify the device included in the meta information of the Web page.

  The indexing DB 24 shown as an example in FIG. 4B uses the ID 24a as key information, a URL (Uniform Resource Locator) 24b indicating Web page position information, a Web page feature word 24c specified by the URL 24b, and a page weight 24d. , The compatible device 24e and the device word 24f are stored.

  The URL 24b is Web page position information and is used as content link data to be output as a search result. The URL 24b can also be used as an index of a Web page stored in the collection Web page DB.

  The feature word 24c stores a feature word that is a phrase representing a feature related to the Web page. The feature word is, for example, morphological analysis of the text data of the Web page to extract words included in the Web page, and for each word, TF (Term Frequency), which is an index based on the appearance frequency of the phrase. It is specified by weighting a word using IDF (Inverse Document Frequency).

  The page weight 24d stores a page weight indicating the characteristics of the Web page. For example, when the page weight is the number of web pages to which the web page is linked, the stored page weight value is a value calculated by another device connected via the communication network 3. This page weight 24d is used for determining the display order of the link data of the Web page.

  The compatible device 24e stores device information that is optimal for browsing web pages. The device word 24f stores a device word that determines the device information stored in the compatible device 24e.

  Note that the page weight 24d of the present embodiment stores the number of link data, but a click history that is the number of clicks on a Web page, a score of a feature word, or the like may be used. Further, the page weight 24d may be replaced with another index other than the above-described ones that indicate the features related to the Web page.

[Example of determining compatible devices]
Next, a method for determining a suitable device will be described. FIG. 5 is a diagram illustrating an example of determining a suitable device according to the present embodiment.

  FIG. 5A shows a display screen 30 of iPhone 5. Five icons 31 are arranged on the display screen 30. The icon 31 is an image having a capacity of less than 2 MB. iPhone 5 is characterized in that it displays a screen on which web clip icons, which are icons of small images of less than 2 MB (megabytes), are arranged. FIG. 5B shows a program 40 for displaying FIG. The program 40 is meta information that can be displayed when a Web page is converted into text data. The program 40 shows a word 41 written “iui.css” and a word 42 written “iui.js”.

  Here, FIG. 5B is examined using the device determination DB 22 of FIG. The word 41 in FIG. 5B includes a row 51 in which the device word 22a in FIG. 4A is “uii.css”, and the word 42 in FIG. 5B includes the device word in FIG. Each row 52 corresponding to “ui.js” corresponding to 22a corresponds. Therefore, as shown in FIG. 4A, all the compatible devices 22b corresponding to the corresponding row of the device word 22a are “device A”. Therefore, in the web page “http: //www.abc.˜” shown in FIG. 5, the compatible device 24e becomes “device A” (# 1). Note that the device word 24f stores only “iui.css”, which is one of the extracted device words, but may store a plurality of extracted device words.

[Search process flowchart]
Next, a search process that applies the device information described above will be described. FIG. 6 is a flowchart of search processing in the search server 1 according to the present embodiment.

  S <b> 21: The control unit 10 (reception unit 15) receives request data including a search keyword from the terminal 4.

Information used for detecting these devices is stored in the storage unit 20 in advance.

  S23: The control unit 10 (search means 17) searches for a web page including the keyword based on the received search keyword. For the search of the Web page, a Web page stored in the collection Web page DB 26 can be used.

  S24: The control unit 10 (Web page adjusting means 18) adjusts the order in which the link data is arranged from the search result using the indexing DB 24. In this adjustment, first, among the Web pages targeted as search results, Web pages that match the device are extracted based on the indexing DB 24. The extracted Web pages are output in descending order of the values stored in the page weight 24d of the indexing DB 24. For example, consider a case where two Web pages for PC 6 and iPhone 5 are prepared for a Web page on which a similar content is posted. In such a case, by using the device information, when searching with iPhone 5, it is possible to output the web page for iPhone 5 as a search result and not to output the web page for PC 6 as a search result. .

  S25: The control unit 10 creates content in which the link data of the Web page is arranged based on the adjustment result. In this case, the value of the URL 24b in FIG. 4B can be arranged.

  S <b> 26: The control unit 10 (content transmission unit 19) transmits the created content to the terminal 4.

  By doing in this way, the search server 1 considers both the characteristics of the Web page and the suitability of the device of the terminal 4 that transmitted the search keyword in the search of the Web page by the search keyword, and in particular, the device The adjusted search result can be transmitted to the terminal 4 with priority. Therefore, the terminal 4 can output a search result considering the device.
