Description

  The present invention relates to a technique for converting an existing HTML document as a search target and providing a refined search service in providing the Internet and Internet site search service.

  In recent years, as the Internet has become widespread and the number of users has increased, an enormous number of Internet sites have come to exist. The presence of a search site is indispensable for users to browse the information they need from a vast Internet site.

  A typical search site that is supposed to return accurate search results in response to user inquiries is Google (registered trademark). In Google, it is said that more than 8 billion URLs can be searched by operating an automatic information collection program called a robot. In addition, Google gives not only the degree of suitability of information to the search keyword but also a unique score calculated from the number of linked pages for each document (HTML document), and presents the search results sorted in the order of the scores. have. Such a search site effectively functions as a comprehensive search means for obtaining a clue about a page on which information required by a user from an enormous Internet site is posted.

However, what the user expects from the search site is the information related to the query itself, not the page related to the query. When a user makes an inquiry to a search site and browses a linked HTML document of a search result arranged based on a uniquely assigned score, there is a situation where it is found that there is no information desired by the user. . In addition, when the volume of text / content in the linked HTML document is large, or when the display amount of one screen is small, such as a mobile browser on a mobile phone, the user can input the search in the moved linked HTML document. There are cases where it is difficult to reach information including keywords.
JP 2007-128547 A Special table 2007-507798 gazette Lawrence Page, Sergey Brin, Rajeev Mottani, Terry Wingrad, 'The PageRank Citration Ranking: Bringing Order to the Web', 1998, Taher H. Haveliwala, 'Efficient Computation of PageRank', Stanford Technical Report, 1999,

  In the search site and the conventional search site, the search service user can confirm the character string or the sentence including the search keyword, that is, the context of the search result arranged based on the score uniquely given by the search site. After moving to the linked HTML document. Therefore, when the user moves to the link destination and browses the actual HTML document, there is a situation where it is found that the information desired by the user does not exist. In addition, when the volume of text / content in the linked HTML document is large, or when the display amount of one screen is small like a mobile browser on a mobile phone, the user inputs in the moved linked HTML document. There are cases where it is difficult to reach information including search keywords.

  An object of the present invention is to provide a search service that allows a user to quickly reach desired information. In particular, the search service user can narrow down the candidate HTML documents before moving to the link destination by looking at the search result, and can narrow down and display the location of the relevant information in the moved link destination HTML document. It is an object.

  In order to solve the above problem, as described in claim 1, the narrow search service providing method of the present invention provides a search service user with a search function in units of pages and sentences or character strings by a Web browser. A refined search service providing method for providing a search function in units of pages and sentences or character strings by a mobile browser to a mobile search service user, from an existing HTML document By extracting all text contents and inserting anchor tags having a series of name attributes before and after each of a character string divided by tags and a sentence divided by punctuation, the existing HTML document is converted into a page. HTML that supports search functions in units and sentences or character strings A search keyword for a search keyword input from a Web browser or a mobile browser, and a step of saving information necessary for the search function including a sentence or a character string itself. A step of displaying a first search result in units of pages and a second search result in units of sentences or character strings including a search keyword, and in a linked HTML document to be displayed by clicking on the second search result And a step of providing a search function characterized by reflecting a search result in units of sentences or character strings including a search keyword.

  In addition to the above-described features, the second search result is related to the HTML document when there are a plurality of search results in units of sentences or character strings including the search keyword. The display is performed in units of sentences or character strings including a plurality of the search keywords.

  Further, in addition to the above-described features, the reflection of the search keyword and the second search result is not only displayed by marking the search keyword but also text including the search keyword. The link HTML document is displayed in a state where the content is focused.

  In addition, as described in claim 4, when the search keyword and the second search result are reflected, the second search result in units of sentences or character strings including a plurality of corresponding search keywords is displayed by clicking. The linked HTML document is displayed in a state where the selected sentence or character string is focused.

  In addition, as described in claim 5, the first search result in page units is characterized by an arrangement order reflecting the number of sentences and character strings including the corresponding search keyword in each HTML document. .

  In addition, as described in claim 6, the narrow search service providing program of the present invention extracts all text contents from an existing HTML document, and extracts text strings divided by tags and sentences divided by phrases. By inserting anchor tags having a series of name attributes before and after each, the existing HTML document is converted / saved into an HTML document corresponding to a search function in units of pages and sentences or character strings. Alternatively, a step of storing information necessary for the search function including the character string itself, and a first search result in page units including the search keyword with respect to the search keyword input from the web browser or the mobile browser, And second search by text or character string unit containing search keyword A step of displaying a result; and a step of providing a search function characterized by reflecting a search result in units of sentences or character strings including a search keyword in a linked HTML document to be displayed by clicking the second search result; Are executed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing an embodiment of a system in which the narrowing search service providing method of the present invention is implemented. In this embodiment, the search service user 119 makes an inquiry as a search keyword by operating the Web browser 118. Alternatively, the mobile search service user 117 makes an inquiry as a search keyword by operating the mobile browser 116. S201 to S202 correspond to the flowchart relating to the narrow search service providing system, in FIG.

  The search keyword as an inquiry is communicated to the search service provider domain 108 via the Internet network 109 and reaches the Web server 101. The Web server 101 requests the search server 102, which is a Web application server, to execute a search.

  The search server 102 searches the search service correspondence database 104 using the search keyword as key information [S203]. If there is no corresponding information, the fact is displayed on the Web browser 118 or the mobile browser 116 via the Web server 101 [S204, S205]. When the corresponding information exists in units of sentences or character strings, the search results in units of pages are displayed as in the conventional search engine. At the same time, search results in text and character string units are also displayed. In FIG. 2, S204 and S207 are applicable. If a plurality of search keywords are input, each search keyword exists in the same HTML document, but all search keywords may not exist in the same sentence or character string. In such a case, only search results in page units are displayed [S204, S206].

  A search service user 119 or a mobile search service user 117 who browses Web content displayed on the Web browser 118 or the mobile browser 116 searches the corresponding page by browsing the search results in units of sentences and character strings. A clue about the conformity of information such as how many sentences and character strings that contain keywords and what kind of contents are the sentences and character strings that contain the search keywords. Can be obtained before browsing.

  The search service user 119 or the mobile search service user 117 as a result of seeing the search result in the text or character string unit that provides a clue about the adaptation of more information than provided in the page unit, When the user wants to browse an HTML document that includes a specific sentence or character string, the user clicks on a search result in units of the specific sentence or character string to thereby display a display request for the HTML document that includes the specific sentence or character string. Can be sent against.

  The HTML document display request of the search service user 119 or the mobile search service user 117 is communicated again to the search service provider domain 108 via the Internet 109 and reaches the Web server 101. The Web server 101 uses the search service corresponding to the search service corresponding document generation server 103 in advance only when it is an HTML document display request for a search result in text or character string units, not a search result in page units. A converted HTML document 105 corresponding to the above is displayed. At this time, the Web server 101 marks and processes the search keyword in the converted HTML document 105 by exchanging with the search server 102, and displays the converted HTML document 105 in a state where the corresponding sentence or character string is focused. That is, there is no need for the search service user 119 or the mobile search service user 117 to search again for the corresponding search keyword in the page. In FIG. 2, S208, S210, and S211 correspond. When a search result in a specific page unit is clicked, a link destination (existing) HTML document is displayed [S208 / S209].

  In order to provide such a function to the search service user 119 or the mobile search service user 117, as described above, the search service corresponding document generation server 103 previously converts the converted HTML document corresponding to the narrow search service. It is necessary to generate 105.

  The search service compatible document generation server 103 has a function of generating and storing a converted HTML document 105 by enclosing each text / content with an anchor tag having a name attribute based on information of an existing HTML document. Further, it has a function of extracting the text content itself corresponding to the search and the accompanying information and storing them in the search service correspondence database 104.

  These functions are enabled by a search service providing program in the search service compatible document generation server 103. FIG. 3 is a flowchart of the refinement search service providing program.

  In S301, the file search is started via the Internet or in the domain, and loops until there is no HTML document [S312]. In the case of via the Internet, the file search target is the Web server 112 and the Web server 101 in the domain. If an HTML document is found, the document is divided by the end tag “>” and substituted into a variable (temporarily $ lines) [S302].

  In S304, $ lines divided by the end tag is divided by the start tag “<” and substituted into a variable (temporarily $ contents). The variable $ lines is divided into $ contents [0] and $ contents [1]. As long as there is $ lines, the process loops from S303 to S311.

In S305, text / content determination is performed. If contents exist in $ contents [0], the contents of $ contents [0] are text contents. If there is no content, $ lines configured by $ contents [0] and $ contents [1] is not a text content (see FIG. 4).

$ Contents [0], which is text content, further determines the presence of a punctuation in S306. If there is a punctuation point, it is divided by the punctuation point in S307.

In S308, the length of the text content and the position information in the document are acquired. These pieces of information are necessary mainly for the step [S309] of generating a converted HTML document in which an anchor tag having a name attribute is inserted with text contents as element contents.

In step S309, a converted HTML document in which an anchor tag having a name attribute is inserted is generated and stored as the converted HTML document 105 in the Web server 101 in FIG. When a user inputs a search keyword and inquires by this step of inserting a link in units of sentences or character strings, how many sentences and character strings contain the search keyword in the corresponding HTML document, Confirmed the clues regarding the conformity of information such as the text and character string containing the search keyword before actually moving to the linked HTML document, and moved to the linked HTML document After that, it will be possible to quickly browse the relevant information. A comparative example of the converted HTML document and the existing HTML document is presented in FIG.

In S310, the name attribute inserted in S309 and the text content itself are stored as set information in the search service correspondence database 104 of FIG. This step makes it possible to provide the basic function relating to the processing flow of the converted HTML document in FIG. 2, the focused HTML document display in the S211 flow, and above all the search.
