The receiving unit 310 receives search request information from the terminal device 100 through the communication network 200. The search request information may be input through various user interfaces (UIs) provided to the terminal device. For example, the search request information is an input for inputting a web document provided to the terminal device 100, that is, a search word. Search request information may be input through a search information providing web document including a field (such as a search window or a directory). Here, the user interface (UI) into which the search request information is input may be a mobile platform site or a PC platform site format. The search request information may include the terminal information of the terminal device 100, and the present invention is not necessarily limited to this, but before or after the search result providing system 300 receives the search request information, the terminal device 100 separately receives the terminal information. Information may be received. Here, the terminal information is used as basic data for determining whether to add a mobile site link item and a “mobile screen display” link when providing a search result for the search request information.

The determination unit 320 determines whether the user interface (UI) that has received the search request information has a PC platform site format or a mobile platform site format. Such a determination may be made based on a connection path in which the terminal device 100 that has input the search request information is connected to the search result providing system 300. In an embodiment of the present invention, m. Is a path through which the terminal device 100 provides a user interface (UI) of a mobile platform site. naver. com, it may be determined that the mobile platform site is in the form of a mobile platform site, which is a route for providing a user interface (UI) of the PC platform site. naver. com, it may be determined to be in the form of a PC platform site. Further, based on the terminal information received by the receiving unit 310, it is determined whether the terminal device 100 that has made a search request is the mobile terminal device 110 or the personal computer 120. According to another embodiment of the present invention, the determination of the type of the terminal device 100 of the determination unit 320 is performed when search request information is received through a user interface (UI) configured and provided in the form of a PC platform site. It may be performed only.

If the user interface (UI) is a mobile platform site, the search result providing unit 330 provides search request information requested for a search with reference to the site database 380, that is, a search result page for a search word. , Determine whether there is a mobile platform site mapped to the PC platform site provided in the search result page, and if the mobile platform site exists, provide the site instead of the mobile platform site . If the user interface (UI) is a PC platform site and the terminal device 100 requested to be searched by the determination unit 320 is the mobile terminal device 110, the search request information requested to be searched with reference to the site database 380. When providing a search result page for, determine whether there is a mobile platform site mapped to the PC platform site included in the search result page, and if a mobile platform site exists, add a mobile site link item provide. If there is no mobile platform site mapped to the PC platform site, a link “mobile screen display” link may be added to the search result and provided. Finally, when the user interface (UI) is a PC platform site and the terminal device 100 that has made the search request is the personal computer 120, the search result page for the search request information is provided therein. The PC platform site may be provided as it is without determining whether there is a mobile platform site mapped to the PC platform site.

The site database 380 includes PC platform site information and mobile platform site information mapped thereon.

More specifically, the site database 380 stores arbitrary PC platform site information (for example, a site address, a site description, etc.) through a predetermined user interface (UI), and stores the PC platform site information. Stores meta information, anchor text information, etc. collected by visiting the site. Further, web documents collected on the Internet are stored in the web document database 390, and mobile platform site candidate groups are extracted from the two databases 380 and 390 to determine mobile platform sites. In such a series of operations, the candidate selection unit 340, the determination unit 350, and the mobile site registration processing unit 360 first select the expected mobile URL corresponding to the mobile site candidate selection criteria as the mobile site candidate, and then select it. After determining whether the mobile platform site exists based on the final confirmation result of the mobile site candidate that has been confirmed, and confirming that the mobile platform site exists, the mobile platform site is mapped to the corresponding PC platform site and stored. . Here, if there is a mobile platform site already registered by the user, compare both, and if there is a difference, the information registered by the user will not be updated as more accurate information, or On the contrary, it may be realized to update to the latest information.

Of these, the mobile site candidate selection criteria will be described in detail. The candidate selection unit 340 extracts information related to an arbitrary site or web document stored in the site database 380 and the web document database 390 and then extracted information. Is compared with the mobile site candidate selection conditions set in advance to determine whether or not the mobile site candidate selection conditions are satisfied. If the mobile site candidate selection conditions are satisfied, the mobile site candidate is set as the mobile site candidate URL of the site or web document. Select Here, the information related to an arbitrary site or web document means information used when comparing with mobile site candidate selection conditions, and is stored in one or more of the site database 380 and the web document database 390. Examples include web document information, meta information, anchor text information, site addresses, etc., but are not necessarily limited thereto.

Here, various conditions may be used as mobile site candidate selection conditions in the embodiment of the present invention, and three typical conditions among them will be described in detail below.

Among the mobile site candidate selection conditions, the first condition is to match with a URL pattern for mobile sites, and the candidate selection unit 340 determines that the URL is m. naver. If the address starts with a mobile site address (m, pda, mobile, etc.) like com, the mobile site candidate is selected as it is. In addition, www. naver. In the case of a URL starting from www as in the case of com, a mobile predicted URL obtained by substituting the first character separated by dots with a pattern value for a mobile site may be selected as a mobile site candidate. The pattern value for a mobile site indicates a URL pattern value used as a mobile site. For example, m and mobile can also be used. However, the mobile site pattern value is not limited to this and may be used as a mobile site. Contains pattern values for mobile sites. Continuing the description of the embodiment, the URL is www. naver. com. which is a mobile expected URL substituted with the pattern value m for the mobile site. naver. com may be selected as a mobile site candidate.

Next, of the mobile site candidate selection conditions, the second condition is a specific word that may indicate a mobile site, such as mobile web, mobile site, mobile address, and a combination of the word mobile and a site title. A sentence (hereinafter collectively referred to as a “mobile-related phrase”) and an anchor tag (Anchor tag) that is linked to the mobile-related phrase and can move to a specific URL (hereinafter referred to as this) Are collectively referred to as “anchor text”). When the anchor text is, for example, <A HREF=“m.naver.com”> mobile neighbor </A>, the candidate selection unit 340 is “mobile” which is a word indicating mobile or a combination of mobile and site title. Since “Naver (registered trademark)” is included, the second condition of the mobile site candidate conditions is satisfied, and the URL (that is, m.naver.com) in the anchor tag of the anchor text is changed. It may be selected as a mobile site candidate. Here, a specific word or sentence that may indicate a mobile site basically means that the word "mobile" is described in the anchor text, but is not necessarily limited to this, "smart phone" , “Mobile phone”, “iPhone” (registered trademark), “Android (registered trademark) phone”, etc., may be used based on various words or sentences.

The third condition among the mobile site candidate selection conditions is that the meta information includes an identifier considering the mobile environment, and the candidate selection unit 340 includes, for example, meta name = “viewport”. In some cases, since the third condition among the mobile site candidate conditions is satisfied, the URL may be extracted, and the extracted URL may be selected as the mobile site candidate. At this time, the identifier considering the mobile environment may include various types of meta tags that may be used due to the characteristics of the mobile. For example, the content is considered in consideration of the mobile screen. There is a viewport to be defined, and handheld, mobile, etc. may also be used as one of the identifiers.

The candidate selection unit 340 may set priorities for the above-described various types of mobile site candidate selection conditions, and information related to an arbitrary site or web document so as to correspond to the set priorities. The mobile site candidate may be selected by extracting and comparing the extracted information with the mobile site candidate selection condition. For example, if the first condition that is the URL pattern is set to the first rank, the second condition that is the anchor text is set to the second rank, and the third condition that is the meta information is set to the third rank, the candidate The selection unit 340 determines whether the site address (URL) in the extracted information satisfies the first condition. If the first condition is satisfied, the selection unit 340 sets the www in the URL as the mobile site pattern value. If the mobile expected URL replaced with one or more of the above is selected as a mobile site candidate and the first condition is not satisfied, the mobile site is included in the information extracted using the second condition that is the next priority. To determine whether or not there is a specific word or sentence that may indicate, and whether or not they have anchor text that can be moved to a specific URL, and proceed with the mobile site candidate selection procedure It may be. Mobile site candidates may be selected depending on whether the information sequentially extracted by such a method satisfies the first condition, the second condition, and the third condition, and the comparison order of the conditions is changed. It is obvious to those skilled in the art that the process may proceed with a part omitted. The selected mobile site candidate may be temporarily stored in the site database 380, or may be stored in another site candidate database (not shown).

When the mobile site candidate is selected by the candidate selection unit 340 as described in detail, the determination unit 350 performs a final confirmation operation on the mobile site candidate and determines whether it is a mobile platform site. The final confirmation work may be performed by various methods. For example, the determination unit 350 automatically tries to connect to the URL of the mobile site candidate, and the mobile site candidate can be temporarily detected without causing an error. If a web document is provided, the mobile site candidate may be determined as a mobile platform site, and if an error message including HTTP 404 is transmitted, it may be determined that the mobile site candidate web document does not exist. The mobile site candidate may be deleted. In other embodiments, such final confirmation work may be performed individually by an administrator.

When the mobile site candidate is determined as the mobile platform site through the determination unit 350, the mobile site registration processing unit 360 automatically enters the site database 380 as the mobile platform site without requiring another additional information input procedure. It may be stored, or when there is a corresponding PC platform site, it may be mapped to the PC platform site and stored in the site database 380. Alternatively, according to another embodiment of the present invention, a PC platform site that provides a series of procedures for registering a mobile platform site and provides the site or web document to the site database 380 upon receiving information on the mobile site. You may map it to and save it.

Prior to registration of the mobile platform site, the mobile site registration processing unit 360 may provide a query result by a query request as to whether or not there is a mobile platform site already registered with reference to the site database 380, and the mobile If the platform site is already stored in the site database 380, the mobile platform site information detected in the site database 380 may be provided so that the mobile platform site information can be modified.

If the mobile platform site is not registered in the site database 380, the mobile site registration processing unit 360 receives the mobile site registration request, provides the mobile site registration related page by the received search registration request, and inputs the mobile site information. Receive. The input mobile site information may be stored in the site database 380 and may be mapped to a PC platform site that displays the web document to store the mobile platform site.

When the search result providing unit 330 provides the search result list requested by the terminal device 100, the search result providing unit 330 connects the terminal device 100 identified by the determination unit 320 to the search result providing system 300 provided to the mobile platform site. It is determined whether the search request information is transmitted or the search request information is transmitted by connecting to the search result providing system 300 provided to the PC platform site. As described above, such a determination may be made based on a connection path of the terminal device 100 to the search result providing system 300. If the mobile platform site is connected to the search result providing system 300 provided to the mobile platform site, and there is a mobile platform site mapped to the PC platform site included in the search result page with reference to the site database 380, the PC Provide a platform site instead of a mobile platform site.

If it is connected to the search result providing system 300 provided on the PC platform site, based on the type determination of the terminal device 100 identified by the determination unit 320, if the type is the mobile terminal device 110, the site If there is a mobile platform site mapped to the PC platform site included in the search result page with reference to the database 380, a mobile site link item that can be linked to the PC platform site and the mobile platform site is additionally provided. If there is no mobile platform site mapped to the PC platform site included in the search result, a link such as “mobile screen display” may be provided. As described in the definition of the search result page, the PC platform site, and the mobile platform site, the PC platform site included in the search result page and the mobile platform site mapped thereto include the site and the web document. It is not limited to specific contents as long as it has a meaning that collectively refers to various web documents provided as search results for search request information, and can be derived as search results. It is normal in the art to be interpreted in the broadest sense including sites, shopping information, news, knowledge iN, general web documents, blogs, cafes, dictionaries, music, maps, specialized information, images, book information, videos, etc. It is obvious to those who have knowledge of According to other embodiments of the present invention, the “mobile screen display” link may be provided with or without the presence of a mobile platform site mapped to the PC platform site. When a mobile platform site is selected from the provided search result list through the terminal device 100 or a mobile site link item is selected through the mobile terminal device 110, the mobile device is directly connected to the selected mobile platform site, and “mobile screen display” is selected. Is selected by the user, the corresponding PC platform site is switched to be suitable for the mobile terminal device 110 by the screen information switching processing unit 370 as described in detail below, and the switched web document is transferred to the mobile terminal device 110. provide. On the other hand, when the search result page requested by the personal computer 120 connected to the search result providing system 300 provided on the PC platform site is provided, it is mapped to the PC platform site included in the search result page. Even if a mobile platform site exists, a search result page including only the PC platform site is provided to the personal computer 120 without adding a mobile site link item.

When the “display mobile screen” link is selected through the search result provided to the mobile terminal device 110, the screen information switching processing unit 370 is installed in the mobile terminal device or mobile terminal device, such as the size of the mobile screen such as the resolution. The PC platform site is switched so as to be suitable for the mobile terminal device 110 in consideration of the limited performance of the web browser.

Specifically, when the screen information switching processing unit 370 determines that the “mobile screen display” link provided from the mobile terminal device 110 to the web document for which the corresponding mobile platform site does not exist has been selected, it corresponds. Using the URL of the PC platform site, the contents of the web document existing at the URL are received. Thereafter, the received web document content is switched to be suitable for the mobile terminal device, and then the switched web document is provided.

The specific content that the screen information switching processing unit 370 switches the web document is performed in consideration of the screen size of the mobile terminal device 110, a plug-in that can be executed by the web browser, and the like. As an example, a method of switching a horizontal arrangement of a web document to a vertical arrangement, a method of switching to a multi-page so that it is not inconvenient to browse a web document page with a limited screen size, and a web document loading speed A method for switching an image platform page of a web document to a text platform page in consideration of the above, Adobe Flash (registered trademark) of Adobe, and Silverlight (Microsoft) of Microsoft (registered trademark) (Right) (registered trademark) and the like, which may include a method of excluding a rich Internet application (RIA) that is not supported by the web browser of the mobile terminal device 110 from the web document. The content of the PC platform site is switched so as to be optimized for the screen size and limited characteristics of the terminal device 110.

Alternatively, the search result providing unit 330 may further provide the mobile terminal device 110 with a plurality of mobile directories and the number of clicks of popular sites through the search providing web document. A favorite function may be added to the mobile platform site of the directory selected from the above. At this time, when a favorite is selected from the mobile terminal device 110, the search result providing unit 330 can store the information of the selected favorite mobile platform site in the favorite storage space, and the search result providing unit 330 stores the favorite storage platform in the favorite storage space. When there is a request to edit the mobile platform site, the order of listing saved favorites may be changed, or the saved favorites may be deleted.

The 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 for explaining the search result providing method of the mobile search result providing system according to the embodiment of the present invention, and FIG. 4 explains the first embodiment of the database construction related subroutine shown in FIG. FIG. 5 is a flowchart for explaining the second embodiment of the database construction related subroutine shown in FIG.

Referring to FIG. 3, the search result providing system 300 according to the embodiment of the present invention performs a site database construction related subroutine for mapping a PC platform site and a mobile platform site to construct a site database 380 (S100).

The first embodiment of the site database construction related subroutine (S100) will be described in detail with reference to FIG. 4. In step S101, the candidate selection unit 340 of the search result providing system 300 includes the site database 380 and the web document database 390. Extract information related to any site or web document stored in. As described above, information related to an arbitrary site or web document refers to information that can be used in comparison with mobile site candidate selection conditions, and includes at least one of the site database 380 and the web document database 390. Examples of such information may include web document information, meta information, anchor text information, site addresses, etc., but are not necessarily limited thereto.

Next, the candidate selection unit 340 determines whether the information extracted in step S103 satisfies the mobile site candidate selection condition. Here, the mobile site candidate selection condition is any one or more of the first condition, the second condition, and the third condition described above.

If at least one of the mobile site candidate selection conditions is satisfied as a result of the determination in step S103, the candidate selection unit 340 selects a mobile predicted URL of the site or web document as a mobile site candidate in step S105. As described above, the candidate selection unit 340 may set the priority order of the mobile site candidate selection conditions, and when the priority order is set, the candidate selection unit 340 may perform the determination according to the priority order.

Next, in step S107, the determination unit 350 performs a final confirmation operation on the selected mobile site candidate. Here, the final confirmation work may include a test for automatically trying to connect to the URL of the mobile site candidate and whether or not a web document provided by the URL exists.
