BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of creating a database in a search system for providing information on a predetermined website on the Internet on which various kinds of information are located, and to a search system including a created database. More particularly, the present invention relates to a method of creating a database in a retrieval system that enables more detailed retrieval of information on a predetermined website, and a retrieval system including the database.

Conventional search engines such as AltaVista (http://www.altavista.com), Lycos (http://www.lycos.com), Yahoo (http://www.yahoo.com), and the like, typically have website information. A database for classifying, storing, and managing the data according to predetermined criteria, a search robot implemented as software for mechanically collecting new website information while continuously circulating on the web, and storing the collected data as a database. It consists of search engine software that allows a user using a search engine to search. A block diagram of the overall system for providing such a conventional search engine service is shown in FIG. Referring to FIG. 1, a user accesses the search engine server 150 through the Internet through the user terminal 110. When a user enters a predetermined search term, the search engine server 150 queries the search engine software 140 for website information about the search term, and the search engine software 140 queries the corresponding database 130. Search and inform the website information. As described above, the search robot 120 is an entity implemented in software for mechanically collecting new website information from the web server 160 while continuously circulating on the web. The search robot 120 searches a sentence described in HyperText Markup Language (HTML) on a network, parses the described link destination, and collects data from the web server 160 existing on the network. As such, the data collected by the search robot 120 is made into a database. In this case, the database is performed by performing morphological analysis on predetermined information located on a website and creating an index page. It means a series of procedures to be stored in 130. The database 130 is for storing all website information collected by the search robot 120. Search engine software 140 functions to present search results to the user. The software searches numerous pages stored in the database 130 and lists the search results in order of accuracy matching the search terms. In FIG. 1, the search server 150 and the search engine unit 120, 130, and 140 are illustrated as separate entities, but for convenience of description, the same may be the same entity.

As described above, various methods for processing predetermined website information collected using a search robot and providing the same to a user have been developed. One of them categorizes a website into a predetermined category and searches only within the category. It is a so-called "category (directory) search" service that allows a precise search to be performed rather than a conventional search service.

This narrow search range can be recognized to some extent in terms of category information "collecting high quality information through limited search", while from the user's point of view, "search for various information" There is a problem that does not meet the needs.

In addition, according to the category search method according to the prior art, the user can search the information of the website belonging to a specific category, the information about the sub-category included in the category can be searched only if you move to the corresponding sub-category There is this. Because of these problems, another problem that the accuracy of the search becomes poor when a user who is not good at searching searches for predetermined information in the upper or lower category instead of the category in which the information he wants to find is located.

In addition, according to the related art, the webpage search providing method receives a predetermined search word from a user and provides the user with a plurality of website information corresponding thereto, but does not support a search function for the website itself. There is a problem.

For example, if you type "Patent Office" into the search box, only a brief description of the Office is provided, and only the information about the Office's universal resource locator (www.kipo.go.kr) is provided. In order to search for a predetermined document included therein, it is inconvenient to move to the JPO website and use a predetermined search box configured separately in the JPO website.

Therefore, as well as a precise search such as category search as described above, it is possible to appropriately provide the level of information desired by the user, such as a normal web document search, search system that can also search the web page contained in a predetermined website If this can be implemented, the convenience of the user using the search service can be maximized, and the utilization of the search service can be greatly improved.

The search system including the database creation method and the created database in the search system according to the present invention has been devised to solve the above-mentioned problems, and it is desired to search for more information by reinforcing the category search service provided by the conventional search service. The purpose is to meet the needs of users.

In addition, the search system including the database creation method and the created database in the search system according to the present invention solves the problem that the search range is within the corresponding category area in the conventional category search service, and also the information on the sub-categories of the category Its purpose is to provide a search service that can be searched.

In addition, the search system including the database creation method and the created database in the search system according to the present invention provides a broader search range to the search service user, thereby accurately searching for the desired information according to the user's search ability. Its purpose is to make it possible to provide search services.

In addition, the database creation method and the search system including the created database in the search system according to the present invention enables the web page search for one or more sub-categories included in a predetermined category, thereby providing a search service provider's scope of search service provider The aim is to make it wider.

In addition, a search system including a database creation method and a created database in a search system according to the present invention enables a search for one or more web pages included in a predetermined website, thereby providing a search service user and a predetermined website operator. Its purpose is to aim at convenience.

In order to achieve the above object, a method for creating a database including a predetermined index page in a search system according to an aspect of the present invention, wherein the index page is a universal resource locator field of a registered site, the corresponding site identifier field A universal resource locator field of a web page included in the site, a page identifier field corresponding thereto, and a source file field of the web page. Collecting information and acquiring a source file of the web page; The universal resource locator of the registered site is extracted from the collected information and recorded in the universal resource locator field of the index page, a predetermined site identifier is assigned to the universal resource locator of the registered site, and the site identifier field is assigned. Recording on; The universal resource locator of the web page included in the site is extracted from the collected information and recorded in the universal resource locator field of the web page of the index page, and a predetermined page identifier is assigned to the universal resource locator of the web page. Recording it in the page identifier field; And recording the obtained web page source file in a source file field of the web page of the index page.

In addition, a search system according to an aspect of the present invention, a web page information database for recording a predetermined index page; A keyword index database that records a predetermined keyword and a page identifier corresponding to the universal resource locator of the web page including the keyword; And a search robot for circulating a registered website to collect information of the web page included in the registered site, and to obtain a source file of the web page, wherein the index page recorded in the database is registered. And a universal resource locator field of a site, a site identifier field corresponding thereto, a universal resource locator field of a webpage included in the site, a page identifier field corresponding thereto, and a source file field of the webpage.

Hereinafter, a method of creating a database in a search system and a search system including a created database will be described in detail with reference to the accompanying drawings.

<How to create a database>

The database creation method and search system in the search system according to the present invention operate to create one or more databases to provide a predetermined search service. In addition, the database created according to the database creation method in the search system according to the present invention includes one or more index pages.

As will be appreciated by those skilled in the art, indexing refers to converting data collected by a search robot as it traverses multiple websites into a format in which a search can be performed in a search engine. In general, indexing by a search engine means having the data organized so that the search can be performed by the search engine without any typical fields. However, in some cases, indexing by search engines is almost the same as indexing in a database. In the case of AltaVista, the data is indexed so that it can be searched by specifying the title, content, and URL of the web document. The index page is generally composed of a Uniform Resource Locator (URL), keywords, attribute information, and the like.                     

2 is a diagram illustrating an index page structure of a web page information database according to an embodiment of the present invention.

Referring to FIG. 2, index pages recorded in the webpage information database include "site identifier", "site universal resource locator (URL)", "site title", "site description", "Category identifier (ID)" to which the site belongs, "page identifier (ID)" of one or more webpages contained in the site, "webpage universal resource locator (URL)", and "hypertext contained in the webpage" Markup Language (HTML) Data "field.

Site identifiers (IDs), category identifiers (IDs), page identifiers (IDs), and the like shown in FIG. 2 may be arbitrarily assigned in a database creation method in a search system according to the present invention. Any form of code may be used as long as it satisfies the condition of being the only identifier that can identify the site, which corresponds to only one of the sites of. In addition, the category identifier (ID) is also a unique identifier corresponding to one category classification used in the database creation method in the search system according to the present invention, and the page identifier (ID) also corresponds to each of one or more web pages included in the website. Any form of code can be used as long as it satisfies the condition of a unique identifier for each web page.

The index page recorded in the webpage information database shown in Fig. 2 is given "sIDxxxxxx" as the site identifier, the universal resource locator of the site is "www.naver.com", and the site title is "Naver", the site. The description is "search site" and the category identifier is "cIDyyyyyy". The site may also include one or more web pages, each of which is assigned a page identifier as a unique identifier. 2, "pIDzzzzzz_1" is an example of a page identifier, www.naver.com/xxx is a web page universal resource locator corresponding to the page identifier, and hypertext markup language data included in the web page is " <title " = "naver"> …… "is recorded respectively.

The index page recorded in the web page information database shown in FIG. 2 may be created through a process of classifying data collected mechanically by each search website while the search robot traverses each website. First, all the information of the webpage included in the website is collected for a specific website, the site identifier is given to the website, and recorded in the index page of the webpage information database. Record the Locator, Title, Description, and Category Identifier for the category to which the website belongs. In addition, the web page information database is provided by assigning a predetermined page identifier to each of the web pages included in the website, and recording various information on the web page identified by the page identifier in an index page of the web page information database. It is possible to write.

In the index page recorded in the keyword index database shown in FIG. 3, page identifiers (pIDxxxxxx_3, pIDxxxxxx_7, etc.) of web pages in which "patent" as a keyword and a keyword "patent" are included in hypertext markup language data are recorded, respectively. It is.

The index page of the keyword index database shown in FIG. 3 selects a predetermined keyword and records the keyword in a keyword field, and analyzes HTML sources of a plurality of web pages collected by a search robot to determine the page identifier of the web page including the keyword. It may be created by recording in a page identifier field, or may analyze the HTML data in the "Page HTML" field by referring to the webpage information database, extract a page identifier containing a specific keyword, and then extract the page identifier in the page of the keyword index database. It can also be created by writing to the identifier field. In addition, as another example of a method of creating a keyword index database, HTML data of a web page collected by a search robot is analyzed to perform morphological analysis, and a predetermined keyword (eg, noun or proper noun, etc.) is extracted. The extracted keyword is recorded in a keyword field of an index page of the keyword index database, and a page identifier of a web page including the keyword is recorded in a page identifier field of the index page. In the case of the method, it is also possible to implement to record the keyword in the keyword index database every time a keyword is extracted, or to record the keyword in the keyword index database when the keyword is extracted more than a predetermined number of times. It is also possible to implement using a keyword index database that has already been created in existing search engines.

Referring to Figure 6, the category web document search method according to an embodiment of the present invention includes the following steps.

Maintain a database of web page information (step 601). The webpage information database may be the webpage information database shown in FIG. 2 described above, or may be a database in which only a predetermined field is extracted and recorded separately from the fields of the webpage information database. In the webpage information database, a page identifier of a webpage included in a predetermined website and hypertext markup language data included in the webpage may be recorded.

Maintain a keyword index database (step 602). The keyword index database may be the same as the keyword index database shown in FIG. 3. That is, a predetermined keyword and a page identifier of a predetermined web page including the keyword may be recorded in the keyword index database.

Maintain a category index database (step 603). The category index database may be the same as the category index database shown in FIG. 4 described above. That is, a category identifier corresponding to a predetermined category and a page identifier of a web page classified as belonging to the category may be recorded in the category index database. Although the category index database shown in FIG. 4 also includes a subcategory identifier, the category category document search method using the database according to the present invention shown in FIG. 6 may not record the subcategory identifier.

In steps 602 and 603 described above, the keyword index database and the category index database are derived from the webpage information database described above. According to another embodiment of the present invention, the keyword index database and the category index database are separate databases. It may be configured by temporarily extracting a corresponding field when a user's search request is made using the above-described webpage information database.

A predetermined keyword is input from the user (step 604), and a predetermined category search request is received from the user as a search condition for the keyword (step 605). Steps 604 and 605 may be performed at predetermined time intervals, or may receive a category search request and a predetermined keyword together in one input window and simultaneously receive corresponding information. According to the input keyword, it is determined whether the same keyword as the input keyword exists in the keyword field of the keyword index database by referring to the keyword index database, and a page identifier (first page identifier) corresponding to the same keyword is extracted. (Step 606). In addition, according to the category search request received from the user, it is determined whether a category identifier equal to the received category information exists in a category identifier field of the category index database by referring to the category index database, and corresponds to the same category identifier. The page identifier (second page identifier) is extracted (step 607). The extracted first and second page identifiers may have some of the same and some of them may be different. Since the web page identified by the common page identifier among the extracted first and second page identifiers includes not only the keyword inputted by the user, but also belongs to a predetermined category that the user is searching for, the user wants to search. It can be determined as a web page. In order to obtain the same page identifier among the first page identifier and the second page identifier, the first page identifier and the second page identifier are calculated (step 608). According to a preferred embodiment of the present invention, the operation is to AND the first page identifier and the second page identifier. That is, when ANDing the first page identifier and the second page identifier with each combination, a common page identifier (third page identifier) among the first page identifier and the second page identifier may be extracted. have. There may be various implementation methods for such an AND operation. For example, the page identifier may be implemented to perform an AND operation on both binary data by converting the page identifier into binary data.

If the third page identifier is obtained in step 608, a page identifier identical to a third page identifier among the page identifiers recorded in the page identifier field of the webpage information database is searched by referring to the webpage information database, and the page identifier is obtained. Extract web page information corresponding to step S609. The user interface screen is reconfigured using the webpage information (HTML data included in the webpage) extracted in step 609 and provided to the user (step 610).

<How to retrieve web documents with subcategories>

7 is a flowchart illustrating a flow of a method for searching a sub-category web document using a database created according to a database creation method in a search system according to an exemplary embodiment of the present invention.

Referring to FIG. 7, the method of searching for a sub-category web document using a database according to an exemplary embodiment of the present invention includes the following steps.

The system for providing a website search service according to the present invention maintains a webpage information database (step 701). Step 701 is the same as step 601 of FIG. 6 described above. As described above, a page identifier of a web page included in a predetermined website and hypertext markup language data included in the web page may be recorded in the web page information database.

Maintain a keyword index database (step 702). Step 702 is the same as step 602 of FIG. 6 described above. As described above, a predetermined keyword and a page identifier of a predetermined web page including the keyword may be recorded in the keyword index database.

Maintain a category index database (step 703). Step 703 may be the same as step 603 of step 6 described above. However, in the method illustrated in FIG. 7, a category identifier, a category identifier for a subcategory of a category identified by the category identifier, and an identifier of a webpage classified as belonging to the category may be recorded in the category index database. Can be.

In steps 702 and 703 described above, the keyword index database and the category index database are derived from the webpage information database described above. According to another embodiment of the present invention, the keyword index database and the category index database are separate databases. It may be configured by temporarily extracting a corresponding field when a user's search request is made using the above-described webpage information database.

A user inputs a predetermined keyword from the user (step 704), and receives a search request including a category below a predetermined category as a search condition for the keyword from the user (step 705). Steps 704 and 705 may be performed at predetermined time intervals, or may receive a category search request and a predetermined keyword together in one input window and simultaneously receive corresponding information. According to the input keyword, it is determined whether the same keyword as the input keyword exists in the keyword field of the keyword index database by referring to the keyword index database, and a page identifier (first page identifier) corresponding to the same keyword is extracted. (Step 706). In addition, according to the category search request received from the user, by referring to the category index database, the category identifier field of the category index database searches whether the same category identifier as the received category information exists, and the page corresponding to the same category identifier. The identifier (second page identifier) is extracted (step 707). In addition, it is searched whether there is a category identifier identical to a subcategory of the category information, and a page identifier (third page identifier) corresponding to the subcategory identifier is extracted (step 708). Since the web page identified by the common page identifier (fourth page identifier) among the extracted first and second page identifiers includes not only the keyword inputted by the user, but also belongs to a predetermined category specified by the user as a search target. The user may determine that the web page is a search. In addition, the web page identified by the common page identifier (fifth page identifier) among the extracted first and third page identifiers includes not only the keyword inputted by the user, but also a predetermined category of the user specified as a search target. Since it belongs to a subcategory, it can be determined that the user is a web page to be searched. As such, the first page identifier and the second page identifier are used to obtain the same page identifier (the fourth and fifth page identifiers) among the first page identifier, the second page identifier, the first page identifier, and the third page identifier. (Step 709), and computes the first page identifier and the third page identifier (step 710). According to a preferred embodiment of the present invention, the operation is to AND the first page identifier and the second or third page identifier. That is, when ANDing the first page identifier and the second page identifier with each combination, a common page identifier (fourth page identifier) among the first page identifier and the second page identifier may be extracted. . Similarly, a page identifier (a fifth page identifier) that is common among the first page identifier and the third page identifier may be extracted.

If the fourth and fifth page identifiers are obtained in steps 709 to 710, the fourth and fifth page identifiers among the page identifiers recorded in the page identifier field of the webpage information database with reference to the webpage information database; The same page identifier is retrieved, and webpage information corresponding to the page identifier is extracted (step 711). The user interface screen is reconfigured using the webpage information (HTML data included in the webpage) extracted in step 711 and provided to the user (step 712). Reconstructing the UI screen in operation 712 may be implemented to display the webpage information searched in the current category with priority, and to display the webpage information searched in the subcategory of the current category in a subsequent order.
