JP5331166B2 - Search server and method - Google Patents

Description

  The present invention relates to a search server and method for providing a search result according to a search query received from a user terminal, and more particularly, to a search server and method for providing an input form included in a transition destination Web page as a snippet of a search result. .

  With the development of the network environment, various information is overflowing on the network, and when browsing a Web page, it is common for a user to first perform a search using a search site. In such a search site, various ideas have been made to improve user convenience. As an example, a search site displays a snippet indicating an outline of a Web page when displaying a search result, thereby making it possible to estimate whether the Web page is a page desired by the user.

Regarding such a snippet, for example, in Patent Document 1, as a snippet of a search result, a point indicator is displayed in addition to a summary description of a web page, and a service point is added when the web page is clicked. A Web page search system that enhances user convenience is disclosed.
In recent years, attempts have been made to display information other than the outline of the Web page as a snippet. For example, a rich snippet that displays rich information such as prices of products and services handled on the Web page and user evaluation as a snippet. A mechanism has also been proposed.

The additional content extraction unit 123 extracts, from the additional content database 127, additional content (input form) that is provided when the Web page extracted from the index database 125 is provided to the user terminal 2.
Here, the additional content database 127 will be described with reference to FIG. FIG. 4 is a diagram schematically showing the additional content database 127. The additional content database 127 stores input form information (additional information for site search in the present embodiment) as additional content provided together with the search results provided for each Web page. As will be described later, the additional content database 127 stores input form information for each Web page in response to a request from the search preparation unit 11.
The additional content extraction unit 123 refers to the additional content database 127 and extracts input form information about the Web page extracted from the index database 125.

  Note that the additional content extraction unit 123 may extract the input form information for all of the search result Web pages, or may extract the input form information for only some Web pages. At this time, some of the web pages may be determined based on the search query received from the user terminal 2 or based on the type of the web page (including the web site) as the search result. It is good as well.

In the determination based on the search query, for example, a web page clicked with a predetermined probability (for example, 90% or more) with respect to the search query may be a part of the web page. A web page with a sponsor contract for each search query (a so-called web page displayed as a sponsored search) may be a part of the web page. In order to enable determination based on such a search query, as shown in FIG. 4, information on a search query from which input form information should be extracted for each Web page may be stored in the additional content database 127. .
Further, in the determination based on the type of the Web page as a search result, for example, a Web page expected to use an input form (in-site search) such as a shopping site or a video site is assumed to be a part of the Web page. Also good. In order to enable the determination based on the type of the Web page, as shown in FIG. 2, the type of the Web site including the Web page is stored in the index database 125 for each Web page as a search result. It is good.

  The search result transmission unit 124 adds the snippet information extracted from the content database 126 and the input form information extracted from the additional content database 127 to each of the Web pages as the search results extracted from the index database 125. The result page is transmitted to the user terminal 2.

As described above, when the search execution unit 12 receives a search query from the user terminal 2, as a search result based on the search query, in addition to the Web page and snippet information of the Web page, the Web page (including a Web site) It also provides input form information.
As a result, the search result page 200 shown in FIG. A search result page 200 shown in FIG. 5 is a search result page based on a search query “XX shopping”, and “XX shopping site (its top page)” is displayed as the search result 201. At this time, the search result 201 includes an input form 201 </ b> B that is used for a search within the site of “XX shopping site” in addition to the snippet 201 </ b> A of “XX shopping site”.
In such a search result page 200, the user of the user terminal 2 can execute an in-site search for “◯ × shopping site” by inputting a query to the input form 201 </ b> B of the search result 201. Note that in the search result page 200 in the search site, the user terminal 2 has a specific configuration for executing a search in the site for the search result Web page, that is, the transition destination Web page “XX shopping site”. This will be described later using the configuration of the form execution unit 29.

  The specific configuration of the search execution unit 12 has been described above. In the present embodiment, the index database 125, the content database 126, and the additional content database 127 are provided separately in order to reduce dynamic processing at the time of receiving a search query. However, the present invention is not limited to this. Any database among the databases 125 to 127 may be integrated.

[Search preparation unit 11]
Next, a specific configuration of the search preparation unit 11 that generates the databases 125 to 127 used by the search execution unit 12 to provide search results will be described with reference to FIG.
With reference to FIG. 6, the search preparation unit 11 includes a snippet information acquisition unit 111, an input form information acquisition unit 112, and a registration unit 113. Note that the search preparation unit 11 may include an acquisition destination URL database 114, a click log database 115, and an acquisition destination URL specifying unit 116, as will be described later.

The snippet information acquisition unit 111 circulates the Web page on the network as appropriate, and acquires the snippet information from the Web page. Here, with reference to FIG. 7, acquisition of snippet information by the snippet information acquisition unit 111 will be described. FIG. 7A is a web page 210 that is the top page of “◯ × shopping site”, and FIG. 7B is a source code 220 (HTML) of the web page 210.
The snippet information can be acquired by a person skilled in the art by a known method. As an example, when the outline of the Web page 210 is used as snippet information, the snippet information acquisition unit 111 analyzes the source code 220 of the Web page 210 and describes it in the name attribute “Description” in the meta tag 221 of the source code 220. The snippet information (summary) is acquired by acquiring the processed character string.

Returning to FIG. 6, the input form information acquisition unit 112 circulates the Web page on the network as appropriate, and acquires the input form information from the Web page. Here, with reference to FIG. 7, acquisition of input form information by the input form information acquisition unit 112 will be described.
The input form information acquisition unit 112 analyzes the source code 220 of the Web page 210 and acquires information in the form tag 222 of the source code 220, thereby acquiring input form information.

Here, referring to FIG. 7A, an input form 211 including a category selection field 211A, a site search field 211B, and a search button 211C is displayed on the Web page 210. The category selection column 211A is used for selecting a product category for performing a search from among various product categories handled by the shopping site “XX shopping site”, and the site search column 211B is used for site search. The search button 211 </ b> C is used to execute a site search based on the site search query.
At this time, the select tag 222B in the form tag 222 is a code for describing the category selection field 211A, the input tag 222C is a code for describing the in-site search field 211B, and the input tag 222D has the search button 211C selected. This is the code to write.

By the way, when a predetermined intra-site search query is input to the intra-site search field 211B of the input form 211 included in the Web page 210 and the search button 211C is operated, the intra-site search within “XX shopping site” is executed. Is done. In this respect, the select tag 222B, the input tag 222C, and the input tag 222D in the form tag 222 described above are merely codes that describe the shape of the input form 211 (such as an input box). Cannot be executed.
Therefore, the input form information acquisition unit 112 acquires at least information in the form tag 222A. Here, the action attribute in the form tag 222A describes the address (URI / URL) of the destination program of the query (site search query) input to the input form 211, and the method attribute Describe the transfer method. Further, the name attribute in the input tag 222C describes a name (variable name) that refers to a query (site search query) in the transmission destination program. According to the description of the form tag 222A and the input tag 222C, the in-site search in “◯ × shopping site” is executed by transmitting the in-site search query to a predetermined address.

  By obtaining at least the information in the form tag 222A and the input tag 222C as described above, the search for the Web page of the transition destination is performed based on the input form provided as the search result in the search site managed by the search server 1. Can be executed.

  In the present embodiment, as an input form to be provided as a search result, an input form for in-site search of a transition destination Web page is used. In this regard, the input form information acquisition unit 112 may determine the character string in the form tag 222 and acquire only the form tag 222 including the character string estimated to be the site search. The character string estimated to be a site search can be arbitrarily set, and examples thereof include “search”, “ser”, and “search”.

Returning to FIG. 6, the registration unit 113 stores the snippet information acquired by the snippet information acquisition unit 111 in the content database 126, and stores the input form information acquired by the input form information acquisition unit 112 in the additional content database 127.
Here, in the action attribute in the form tag, the address of the transmission destination program may be described with a relative path instead of an absolute path. At this time, the registration unit 113 preferably corrects the address described in the relative path to an absolute path and stores it in the additional content database 127. For example, referring to FIG. 7B, in the form tag 222A, “/ search” and the address of the relative path are described as the action attribute. At this time, the registration unit 113 corrects the relative path “/ search” as an absolute path “www. ○ × shopping.co.jp / search”, and stores it in the additional content database 127.

By the way, the display area of the input form of the transition destination web page can be freely set by the administrator of the website including the web page, while the display area of the snippet of the search result page is generally constant. Limited to area. With reference to FIG. 7A, the input form 211 of the Web page 210 that is the transition destination Web page has a width that is substantially the same as the width of the Web page 210. On the other hand, referring to FIG. 5, the search result page 200 of the search site managed by the search server 1 divides the screen and displays a sponsored search on the right side. The area is limited to approximately half the width of the search result page 200.
In such a situation, when an input form having a size freely set by the administrator of the destination Web page is displayed as a search result, there is a possibility that the design uniformity in the search result page 200 may be lost. .

Therefore, when there is information defining the size of the input form in the input form information acquired by the input form information acquisition unit 112, the registration unit 113 changes the size to a predetermined size and stores it in the additional content database. To do.
In addition, as information which prescribes | regulates the size of an input form, the size attribute in an input tag is mentioned, for example (refer input tag 222C of FIG. 7 (2)). Thereby, since the administrator of the search server 1 can set the size of the input form to be provided as a search result, the design on the search result page can be unified.

According to the search preparation unit 11 as described above, the input form information acquisition unit 112 acquires input form information from all Web pages. However, the input form information acquisition unit 112 can input input forms only from some Web pages. It is good also as acquiring information.
Therefore, the search preparation unit 11 may include an acquisition destination URL database 114. Here, the acquisition URL database 114 will be described with reference to FIG. FIG. 8 is a diagram schematically showing the acquisition destination URL database 114. The acquisition destination URL database 114 stores Web pages from which input form information is to be acquired.

Some Web pages can be arbitrarily set, and may be determined based on the search query as described above, or determined based on the type of the Web page (including the Web site). It is good to do. That is, for example, it may be a web page (hereinafter referred to as “high-click web page”) that is clicked with a certain probability (for example, 90% or more) with respect to the search query. It may be a Web page that has a sponsor contract with a person, or a Web page that is expected to use an input form (search within site) such as a shopping site or a video site.
In addition, some Web pages can be arbitrarily set, for example, automatically set by various functions of the search server 1 or manually set by the administrator of the search server 1. It is good as well.

  Here, the configuration of the search server 1 for automatically setting a high-click Web page as a Web page from which input form information is to be acquired will be described. The search preparation unit 11 of the search server 1 further includes a click log database 115 and an acquisition URL specifying unit 116.

  The click log database 115 stores, for each search query used in the search site of the search server 1, a Web page provided as a search result based on the search query and a click rate of the Web page. Here, referring to FIG. 9 schematically showing the click log database 115, for example, the click log database 115 includes “www.XX” when the search query “XX shopping” is searched. It is stored that the Web page specified by “shopping.co.jp” is clicked with a probability of “90%”.

  Returning to FIG. 6, the acquisition destination URL specifying unit 116 refers to the click log database 115, specifies a Web page having a search query with a click rate of a predetermined value (for example, 90%) or more, and acquires input form information. This is stored in the acquisition URL database 114 as a high-click Web page to be executed.

  By including such a click log database 115 and acquisition destination URL specifying means 116, the search preparation unit 11 can acquire an input form only from a high-click Web page. As a result, it is possible to accept input to the input form on the search result page before transition for a Web page on which most users transition when a search is performed, and it is possible to improve the overall convenience of search. .

  The specific configuration of the search preparation unit 11 has been described above. When the search preparation unit 11 having such a configuration acquires snippet information and input form information in advance, the search execution unit 12 can also provide the input form of the transition destination Web page in the search result page. it can.

[Form execution unit 21]
Next, a specific configuration in which the user terminal 2 performs an in-site search on the transition destination Web page based on the input form provided on the search result page will be described.
Returning to FIG. 1, the input form transmitted from the search result transmitting unit 124 causes the user terminal 2 to realize the function of the form execution unit 29. Here, the form execution unit 29 includes a form query reception unit 291 and an execution request transmission unit 292.

  The form query receiving unit 291 receives a query (site search query) input by the user of the user terminal 2 via the input form provided on the search result page.

  The execution request transmitting unit 292 transmits the query received by the form query receiving unit 291 to the address specified by the action attribute in the form tag included in the input form information. Thereby, the query input via the input form provided on the search result page is transmitted to the same address as the query input via the input form of the Web page of the transition destination. That is, based on the input form transmitted from the search result transmitting unit 124, the user terminal 2 makes a request for in-site search based on the in-site search query to the input form of the Web page of the transition destination, A process similar to the process based on the input form of the Web page of the transition destination is directly executed from the search result page.

  The specific configuration of the form execution unit 29 has been described above. Thereby, based on the site search query received in the input form provided on the search result page, it is possible to execute the site search on the transition destination Web page.

[Hardware configuration of search server 1]
The hardware of the search server 1 described above can be configured by one or a plurality of general computers. For example, a general computer includes a central processing unit (CPU) as a control unit, and a memory (RAM, ROM), a hard disk (HDD), and an optical disk (CD, DVD, etc.) as a storage unit, and a network communication device. Various wired and wireless LAN devices as display devices, for example, various displays such as liquid crystal displays and plasma displays, and as input devices, for example, keyboards and pointing devices (mouse, tracking ball, etc.) Are connected by a bus line. In such a general computer, the CPU controls the search server 1 in an integrated manner, reads and executes various programs as appropriate, and cooperates with the hardware described above to realize various functions according to the present invention. doing.

[Search preparation process]
The search preparation process will be described with reference to FIG. In FIG. 10, input form information is acquired only from some Web pages stored in the acquisition destination URL database 114.

  S1, S2: The snippet information acquisition unit 111 of the search preparation unit 11 circulates on the network and analyzes the source code of the acquired Web page (S1). Subsequently, the snippet information acquisition unit 111 acquires snippet information from the analyzed source code (S2).

  S3, S4: Next, the input form information acquisition unit 112 of the search preparation unit 11 refers to the acquisition destination URL database 114 and determines whether the Web page acquired in S1 is a Web page from which the input form information should be acquired. Is determined (S3). At this time, if the input page information is a Web page from which the input form information is to be acquired, the input form information acquisition unit 112 includes information described in the form tag of the source code analyzed in S1 (particularly, the action attribute in the form tag). Etc.) (S4).

  S5: Subsequently, the registration unit 113 stores the snippet information acquired in S2 in the content database 126, stores the input form information acquired in S4 in the additional content database 127 (S5), and ends the process.

[Search processing]
Next, the search process will be described with reference to FIG. In FIG. 11, an input form for the transition destination Web page is provided on the search result page, and an intra-site search for the transition destination Web page is executed based on the intra-site search query received in the input form. .
