The mobile terminal 120 provides a search result page that can be dynamically changed accordingly. Specifically, in an embodiment of the present invention, when the user accesses the search result providing system 300 provided to the mobile-based site through the terminal 100 and transmits the search request information, the search result providing system 300 Regardless of whether the connected terminal 100 is a mobile terminal 110 or a personal computer 120, a mobile-based site is provided when a mobile-based site is mapped to a PC-based site included in a search result page. can do. In addition, when the user accesses the search result providing system 300 provided to the PC-based site through the terminal 100 and transmits the search request information, the search result providing system 300 is connected to the mobile terminal 100. The personal computer 120 determines whether the terminal 110 or the personal computer 120 provides the PC-based site included in the search results page without any substitution or addition, and in the case of the mobile terminal 110, the PC. If you have a mobile-based site that maps to the base site, you can also provide a link to the mobile-based site on your PC-based site. Here, the search result page is a web document provided as a search result for the search request information, and if it can be derived as a search result, it is not limited to a specific content, but is an advertisement site, shopping information, news, knowledge in (a service provided by NHN Corporation). Name, general web document, blog, cafe, dictionary, music, map, technical information, image, book information, video, etc.

The search result providing system 300 may provide a mobile-based site corresponding to the selected mobile site link item when the mobile site link item or the link 'mobile screen view' added to the search result is selected from the mobile terminal 120 or the link ' It converts and provides PC-based site corresponding to 'mobile screen view'.

Referring to FIG. 2, the search result providing system 300 includes a receiver 310, a determiner 320, a search result provider 330, a candidate selector 340, a determiner 350, and a mobile site registration processor ( 360, a screen information conversion processor 370, a site database 380, and a web document database 390.

The receiver 310 receives the search request information from the terminal 100 through the communication network 200. The search request information may be input through various user interfaces (UIs) that may be provided to the terminal. For example, a text box (a search box or a text box for inputting a search word or a web document provided in the terminal 100) may be input. Search request information may be input through a search providing web document including a directory). The user interface (UI) for receiving the search request information may be in the form of a mobile based site or a PC based site. The search request information may include terminal information of the terminal 100. The present invention is not limited thereto, and the search result providing system 300 separately from the terminal 100 before or after receiving the search request information. May be received. The terminal information is used as basic data for determining whether to add a mobile site link item and a link 'mobile screen view' when providing a search result according to the search request information.

The determination unit 320 determines whether the user interface (UI) receiving the search request information is in the form of a PC-based site or a mobile-based site. This determination may be made based on a connection path connected to the search result providing system 300 by the terminal 100 inputting the search request information. In one embodiment of the present invention, when the terminal 100 is connected to the path m.naver.com providing a user interface (UI) of the mobile-based site, it can be determined in the form of a mobile-based site, PC-based If you access www.naver.com to provide the site's user interface (UI), it can be determined as a PC-based site. In addition, based on the terminal information received by the receiver 310 determines whether the terminal 100 is a mobile terminal 110 or the personal computer 120 requested to search. According to another embodiment of the present invention, the determination of the terminal 100 type of the determination unit 320 may be limited when the search request information is received through a user interface (UI) provided in the form of a PC-based site. .

When the user interface UI is a mobile-based site, the search result providing unit 330 provides the search request information, that is, the search result page for the search term, with reference to the site database 380. It determines whether there is a mobile-based site mapped to the PC-based site provided among the search result pages, and if the mobile-based site exists, it is replaced with the mobile-based site. If the user interface (UI) is a PC-based site and the terminal 100 searched by the determination unit 320 is the mobile terminal 110, the search request information requested for searching with reference to the site database 380. When providing a search result page for, it is determined whether there is a mobile-based site mapped to the PC-based site included in the search result page, and if the mobile-based site exists, the mobile site link item is added and provided. If a mobile-based site does not exist that maps to a PC-based site, a link 'mobile screen view' may be added to the search results. Finally, when the user interface (UI) is a PC-based site and the terminal 100 for which the search is requested is the personal computer 120, when the search result page for the search request information is provided, the user interface (UI) is mapped to the PC-based site provided therein. PC-based sites can be provided as is without determining whether a mobile-based site exists.

The site database 380 includes PC-based site information and mobile-based site information mapped thereto.

More specifically, the site database 380 stores a user's information (eg, a site address, site description text, etc.) of a PC-based site through a predetermined user interface (UI), and stores the web. Stores meta information, anchor text information, etc. collected by crawlers by visiting the site. In addition, the web document database 390 stores web documents collected from the Internet, and extracts a mobile-based site candidate group from the two databases 380 and 390 to determine a mobile-based site. Such a series of operations are first performed by the candidate selecting unit 340, the determining unit 350, and the mobile site registration processing unit 360 to first select a mobile predicted URL corresponding to the mobile site candidate selection criteria, and then to the mobile site candidate. After determining whether the mobile-based site exists, the mobile-based site is mapped to the corresponding PC-based site and stored. In this case, when there is a mobile-based site previously registered by the user, the mobile-based site may be prepared in contrast with each other and may not be updated by considering the information registered by the user as more accurate information, or vice versa. .

If the mobile site candidate selection criteria are described in detail, the candidate selecting unit 340 withdraws information related to any site or web document stored in the site database 380 and the web document database 390, and then withdraws the information. The information is compared with the preset mobile site candidate selection condition to determine whether the mobile site candidate selection condition is satisfied, and if the mobile site candidate selection condition is satisfied, the mobile expected URL of the site or web document is selected as the mobile site candidate. . The information related to any site or web document means information that can be used in comparison with the mobile site candidate selection condition, and is stored in at least one of the site database 380 and the web document database 390. For example, web document information, meta information, anchor text information, site address, etc. may be included, but is not necessarily limited thereto.

Herein, the mobile site candidate selection condition may use various conditions according to an embodiment of the present invention, and three representative conditions thereof are described in detail below.

Among the mobile site candidate selection conditions, the first condition is whether or not the URL pattern for the mobile site matches, and the candidate selecting unit 340 has a mobile site address (m, pda, mobile, etc.), for example, m.naver.com. In the case of an address starting with a mobile site candidate is immediately selected. In the case of a URL starting with www, such as www.naver.com, a mobile predicted URL may be selected as a candidate mobile site by replacing the initial www character separated by a dot with a pattern value for the mobile site. The pattern value for a mobile site represents a URL pattern value that can be used as a mobile site, and may be, for example, m, and mobile may also be considered. Can be included. Continuing to describe the above embodiment, when the URL is www.naver.com, the mobile predicted URL m.naver.com, which is replaced using the pattern value m for the mobile site, may be selected as the mobile site candidate.

Next, the second condition of the mobile site candidate selection condition is a specific word or sentence that may refer to a mobile site such as a mobile web, a mobile site, a mobile address, and a combination of a mobile and a site title (hereinafter, referred to as a 'mobile phrase'). And anchor case (hereinafter referred to as 'anchor text'), which is linked to a mobile related phrase and can be moved to a specific URL. The candidate selecting unit 340 includes the word "mobile naver" indicating a mobile or a combination of mobile and site titles when the anchor text is <A HREF="m.naver.com"> mobile naver </A>. Since the second condition among the mobile site candidate conditions is satisfied, the URL (ie, m.naver.com) surrounded by the anchor tag in the anchor text may be selected as the mobile site candidate. Here, a specific word or sentence that may indicate a mobile site basically means the case where the word "mobile" is written in the anchor text, but is not necessarily limited thereto, and is not limited to "smartphone", "cellphone", "iphone", and "android phone". Or various words or sentences.

In addition, the third condition among the mobile site candidate selection conditions includes a case where the meta information includes an identifier in consideration of the mobile environment, and the candidate selecting unit 340 determines that the meta information is meta name = "viewport". If the third condition among the mobile site candidate conditions is satisfied, the corresponding URL may be withdrawn and the extracted URL may be selected as the mobile site candidate. In this case, the identifier considering the environment of the mobile may include various types of meta tags that may be used due to the characteristics of the mobile. For example, a viewport that may determine content in consideration of the screen of the mobile. In addition, handheld and mobile may be used as one of the identifiers.

The candidate selecting unit 340 may set priorities among the various types of mobile site candidate selection conditions described above, and withdraw information related to an arbitrary site or web document according to the set priorities and the information extracted and the corresponding mobile site. Mobile site candidates may be selected by comparison with candidate selection criteria. For example, when the first condition that is the URL pattern is set to the first rank, the second condition that is the anchor text to the second rank, and the third condition that is the meta information to the third rank, the candidate selecting unit 340 may set the first condition. In the extracted information, it is determined whether the site address (URL) satisfies the first condition, and if the first condition is met, the mobile predicted URL in which the www is replaced with one or more of the mobile site pattern values is selected as the mobile site candidate. If the first condition is not satisfied, the mobile site is determined by using a second condition, which is a next priority, to determine whether there is a specific word or sentence that can represent the mobile site and anchor text that can be moved to a specific URL. You may continue with the nomination process. In this manner, candidates for mobile sites may be selected based on whether information withdrawn in order satisfies the first, second and third conditions, and the comparison order of the conditions may be changed or partially omitted. It is obvious to those skilled in the art. The selected mobile site candidate may be temporarily stored in the site database 380 or may be stored in a separate site candidate database (not shown).

When the mobile site candidate is selected by the candidate selecting unit 340 as described above, the determination unit 350 determines whether the mobile site is a mobile site candidate by performing a final verification operation. The final verification may be performed by various methods. For example, if the determination unit 350 attempts to automatically connect to the URL of the mobile site candidate, and the web site of the mobile site candidate is provided without error, the corresponding mobile site is provided. If the candidate is determined to be a mobile-based site, and an error message including HTTP 404 or the like is delivered, it may be determined that the web document of the mobile site candidate does not exist, and thus the mobile site candidate may be deleted. In another embodiment, this final confirmation may be performed individually by the administrator.

When the mobile site candidate is determined to be a mobile-based site through the decision unit 350, the mobile site registration processor 360 automatically sets the mobile-based site as a mobile-based site to the site database 380 without additional additional information. Alternatively, if a corresponding PC-based site exists, it may be mapped to the corresponding PC-based site and stored in the site database 380. Alternatively, according to another embodiment of the present invention, by providing a series of procedures for registering a mobile-based site receives the information of the mobile site and mapping with a PC-based site that provides the site or web document in the site database 380 It can also be stored.

Prior to the registration of the mobile-based site, the mobile site registration processing unit 360 may provide a search result according to a query request of whether a pre-registered mobile-based site exists with reference to the site database 380, and the mobile-based site. If is already stored in the site database 380 may provide information of the mobile-based site detected in the site database 380 to modify the information of the mobile-based site.

If the mobile-based site is not registered in the site database 380, the mobile site registration processing unit 360 receives the mobile site registration request and provides the mobile site registration page according to the received search registration request to input the mobile site information. Receive. The received mobile site information may be stored in the site database 380, and may be mapped to a PC-based site displaying the web document so that the mobile-based site is stored.

When the search result providing unit 330 provides a list of search results requested from the terminal 100, the search result providing system performed by the determination unit 320, the terminal 100 is provided to a mobile-based site ( 300 to determine whether to transmit the search request information or to the search result providing system 300 provided to the PC-based site to determine whether to transmit the search request information. As described above, this determination may be made by a connection path to the search result providing system 300 of the terminal 100. If the user accesses the search result providing system 300 provided as a mobile based site, referring to the site database 380, if there is a mobile based site mapped to the PC based site included in the search result page, Provide alternatives to mobile based sites.

If the mobile terminal 110 is connected to the search result providing system 300 provided to the PC-based site, the site database may be determined based on the determination of the type of the terminal 100 performed by the determination unit 320. 380), if there is a mobile-based site that maps to a PC-based site included in the search results page, then add a mobile site link item that can link to the PC-based site and the mobile-based site, and if included in the search result If a mobile-based site does not exist that maps to a PC-based site, it can provide a link such as "view mobile screen." According to the definitions of the search result page, PC-based site and mobile-based site described above, the PC-based site included in the search results page and the mobile-based site mapped to it include the site and the web document. As a general term for various web documents provided as a search result that can be derived from a search result is not limited to a specific content, for example, advertising sites, shopping information, news, knowledge in, general web documents, blogs, cafes, dictionaries, music It will be apparent to those skilled in the art that the present invention may be interpreted in the broadest sense, including maps, professional information, images, book information, videos, and the like. According to another embodiment of the present invention, the link 'mobile screen view' may be provided regardless of the presence or absence of a mobile-based site that maps to a PC-based site. If a mobile-based site is selected through the terminal 100 or a mobile site link item is selected through the mobile terminal 110 in the provided search result list, the mobile terminal 110 is directly connected to the selected mobile-based site, and the link 'view mobile screen' is displayed to the user. When selected by the user, as described below, the corresponding PC-based site is converted to fit the mobile terminal 110 by the screen information conversion processing unit 370, and provides the converted web document to the mobile terminal 110. On the other hand, when providing a search result page requested from a personal computer 120 connected to the search result providing system 300 provided as a PC-based site, the mobile-based site mapped to the PC-based site included in the search result page If present, provide personal computer 120 with search results pages that include only PC-based sites without the addition of mobile site link items.

When the link 'mobile screen view' is selected through a search result provided to the mobile terminal 110, the screen information conversion processing unit 370 considers the mobile screen size, such as resolution, and the limited performance of the web browser mounted on the mobile terminal or the mobile terminal. To convert the PC-based site to suit the mobile terminal (110).

Specifically, when the screen information conversion processing unit 370 determines that the 'view mobile screen' link provided for the web document in which the corresponding mobile-based site does not exist from the mobile terminal 110 is selected, Receive the web document contents existing in the URL by using the URL. Thereafter, the converted web document contents are converted to suit the mobile terminal, and then the converted web documents are provided.

The details of the screen information conversion processing unit 370 converting the web document are made in consideration of the screen size of the mobile terminal 110 and a plug-in that can be executed by the web browser. The image-based page of the web document is considered in consideration of the method of converting the horizontal array of the document to the vertical array, the method of converting the page of the web document into a multipage so as not to be inconvenient for browsing the limited screen size. Rich Internet Applications that are not supported in the web browser of the mobile terminal 110, such as a method of converting to a text-based page, Adobe Flash (Abobe) or Microsoft Silverlight (Microsoft); And RIA) may be removed from a web document. Convert the content of the PC-based site to be optimized for the screen size and limited characteristics of 110).

Optionally, the search result providing unit 330 may provide the mobile terminal 110 with a plurality of mobile directories and the number of clicks of popular sites through the search providing web document, and from among the plurality of mobile directories from the mobile terminal 110. You can add favorites to your mobile-based site in the selected directory. In this case, when a bookmark is selected from the mobile terminal 110, the search result providing unit 330 may store the information of the mobile-based site of the selected bookmark in the bookmark storage space, and store the information of the mobile-based site stored in the bookmark storage space. If there is an edit request, the list order of the saved favorites can be changed or the stored favorites can be deleted.

A search result providing method of the search result providing system having such a configuration will be described with reference to FIGS. 3 to 5 as follows.

FIG. 3 is a flowchart illustrating a search result providing method of a search result providing system according to an exemplary embodiment of the present invention, and FIG. 4 is a flowchart illustrating a first embodiment of a database construction related subroutine shown in FIG. 5 is a flowchart illustrating a second embodiment of the database construction related subroutine shown in FIG.

Referring to FIG. 3, the search result providing system 300 according to an exemplary embodiment of the present invention performs a site database construction-related subroutine that maps a PC-based site and a mobile-based site to build a site database 380 (S100). .

Referring to FIG. 4, the first embodiment of the site database construction related subroutine S100 will be described in detail. In step S101, the candidate selecting unit 340 of the search result providing system 300 is connected to the site database 380. Retrieve information related to any site or web document stored in the web document database 390. As discussed above, information relating to any site or web document means information that can be used in comparison with the mobile site candidate selection criteria and includes at least one of the site database 380 and the web document database 390. It is stored in, and may include, for example, web document information, meta information, anchor text information, site address, etc., but is not limited thereto.

Next, the candidate selecting unit 340 determines whether the information retrieved in step S103 satisfies the mobile site candidate selection condition. The mobile site candidate selection condition may be one or more of the first condition, the second condition, and the third condition described above.

If the determination result of step S103 satisfies at least one mobile site candidate selection condition, in step S105, the candidate selecting unit 340 selects the mobile expected URL of the site or web document as the mobile site candidate. As described above, the candidate selecting unit 340 may set the priority of the mobile site candidate selection condition, and if so, may determine the priority according to the priority.

Next, in operation S107, the determination unit 350 performs a final check on the selected mobile site candidate. Here, the final verification operation may include a test of whether the web document provided by the URL exists by automatically attempting to access the URL of the mobile site candidate, and the final verification result may include a web document provided by the corresponding URL. In this case, the web document provided by the corresponding URL does not exist due to an HTTP 404 error or the like. Final confirmation can be performed in other equivalent ways.

The determination unit 350 determines whether the mobile site candidate having the corresponding URL is a mobile-based site through step S109 based on the result of the final check operation.

As a result of the determination in step S109, when the mobile site candidate is found to be a mobile-based site, that is, when there is a web document provided at the URL of the mobile site candidate, the mobile site registration processing unit 360 selects the corresponding mobile site candidate. The mobile-based site is mapped to the PC-based site and stored in the site database (S111). Alternatively, independently of this, the mobile site registration processing unit 360 may perform a second embodiment of a subroutine related to database construction in parallel, which is described in FIG. 5.

5, the mobile site registration processing unit 360 determines whether a search registration request of the mobile-based site has been received in step S151.

The search result can be provided according to the inquiry request of whether or not the mobile-based site is already registered. If the mobile-based site is already stored in the site database 380, the site database ( Information about the mobile-based site detected at 380 may be provided.

Can be determined. An example of the user interface UI may be a search providing web document including an input field for inputting search request information.

Next, the receiving unit 310 of the search result providing system 300 receives the search request information from the terminal 100 through the communication network 200 in step S300. The search request information may include terminal information of the terminal 100, or terminal information of the terminal 100 may be separately received before or after receiving the search request information.

After the search request information is received, the search result providing unit 330 of the search result providing system 300 performs a user interface provided by the determination unit 320 to receive the search request information. It is checked in step S350 whether the format is a format of a mobile-based site. As described above, this may be distinguished through a connection path for connecting the terminal 100 to the search result providing system 300. As a result of confirming the step (S350), when the terminal 100 is connected to the search result providing system 300 consisting of a mobile-based site, as shown in the portion corresponding to C of Figure 11 through the step (S370) When providing a search result page for the search request information received from the terminal 100, if there is a mobile-based site mapped to the PC-based site included in the search result page, the search is replaced with the mobile-based site. By providing a results page, the PC-based and mobile-based sites included in the search results page include sites and web documents according to their definitions. According to FIG. 11, in the case of 'naver' and 'naver securities', a mobile-based site mapped to a PC-based site exists and replaced with a mobile-based site, and in other cases, such as 'naver weather', a mapped mobile-based site exists. You can see that it was provided as it is.

As a result of checking in step S350, when the terminal 100 is connected to the search result providing system 300 configured as a PC-based site, the terminal transmitting the search request information based on the terminal information performed by the determination unit ( Whether 100 is the mobile terminal 110 or the personal computer 120 is checked in step S400.

As a result of checking the step (S400), if the terminal 100 that transmitted the search request information is a personal computer 120, the search result providing unit 330 of the search result providing system 300 through the step (S450) As shown in FIG. 8, even if a mobile-based site matching the PC-based site included in the search result providing page is registered in the site database 380, only the PC-based site list is provided without providing a link or information related to the mobile-based site. Provide a search results page that includes, where the PC-based site included in the search results page includes a site and a web document according to its definition.

As a result of the checking in step S400, when the terminal 100 transmitting the search request information is the mobile terminal 110, the search result providing unit 330 receives the search request received from the mobile terminal 110 in step S500. When you provide a search results page for information, if a mobile-based site exists that maps to the PC-based site included in the search results page, create a mobile site link entry collinear with or adjacent to that PC-based site. Provide the search results page you added. If there is no mobile-based site mapped to the PC-based site included in the search results page, a link such as 'mobile screen view' may be additionally provided in the same line as or adjacent to the PC-based site. An embodiment of a search results page provided to the mobile terminal 110 through step S500 is shown in FIG. 6. As shown in FIG. 6, if there is a mobile site mapped to the PC-based site, the mobile site link item A is added. If the mobile site is not present, the mobile conversion link item B is added. Able to know. According to another embodiment of the present invention, a mobile conversion link item (B) may be added and provided regardless of whether a mobile site mapped to a PC-based site exists. 6, 8, and 11, only one screen corresponding to the 'site' item is shown in the embodiment of the search result page corresponding to each case, but the term search result page used in the present invention and a PC-based site And mobile-based sites, the PC-based sites included in the search results pages and the mobile-based sites mapped to them collectively refer to various web documents provided as search results for search request information, including sites and web documents. In addition to the 'site' item may include shopping information, news, knowledge in, general web documents, blogs, cafes, dictionaries, music, maps, professional information, images, book information, videos, and the like. Thereafter, the search result providing unit 330 receives from the terminal 100 or the mobile terminal 110 which site or site link is selected from the search results in step S600.
