Description

Method and System for Providing Information Service and Information Search Service by Using Visited Uniform Resource Locator Log}

The present invention relates to a method and a system for providing an information service and an information retrieval service using a user visit UAL log. More specifically, in the information service or information retrieval service using the wired / wireless internet, the UEL log information that users visit or visit is stored and analyzed to measure and grasp the user's information preference, and reflect the information preference to the search algorithm. The present invention relates to a method and system for providing an information service and an information retrieval service for improving a unit of information (Depth), coverage, accuracy, and the like.

In addition, the user visited the UAL log to measure the association between the query, the association between the query and the UEL, the association between the UEL and the combination of these combinations, and the query that was not possible in the simple keyword matching method search using the measured information. Or it relates to a method and system for identifying associations between specific UELs and recommending query and UEL information or combinations thereof.

In order for a user to view a specific web page using a web browser such as Internet Explorer, a user generally needs to input an address of a URL (Uniform Resource Locator) of the web page. Therefore, if the user does not know the address of the URL of the web page, it is difficult to access the target document.

Therefore, even if you do not know the URL information of the Internet site, the software that finds the information you want among the vast amount of information flooding on the Internet has emerged, such software is collectively referred to as a search engine (Search Engine). The principle of the search engine is that a given search program called a search robot or spider program navigates through a number of sites opened on the Internet, stores the information of pre-collected websites into a database, and then the user If entered, only the web sites with contents that match the query entered in the database are presented.

In the early stages of Internet service (eg, first generation), such search engines search and classify each Internet site and web document in a database, and build a database based on the user's keyword search or menu search. As we refine our classification, we use a directory search approach that provides access to the final data.

To register your webpage on a search site that supports directory search, the administrator of the search site registers the URL of this webpage directly, or the administrator of the URL of this webpage can ask the administrator of the search site to There is a way to apply for registration. In this case, the administrator of the search site that received the registration application directly accesses and evaluates the web page, and then decides whether to register the search tool in the category.

Such a directory search method has the advantage of being easy to search while following a pre-categorized subject word if it knows only the kind of information needed, and is fast because it searches information already stored in a database on the search engine side. In addition, there is an advantage that the directory has a high reliability of the document, which is determined by the administrator of the search site to directly evaluate the web page that applied for registration to determine whether to register the web page with low or poor information Because.

However, as the number of websites increased rapidly, as in the first generation search engines, the method of manually checking a single web page and storing the verified web page as a database was not sufficient to keep up with the increasing trend of the website.

For this reason, a second generation search engine has been introduced that introduces the concept of a search robot mentioned above and provides a search service by automatically searching and indexing web pages. The second generation search engine uses a query input method and searches all web documents related to the user's query and provides them to the user's computer. It is inconvenient to find again in the search results screen. Therefore, in order to make up for such drawbacks, despite the huge burden on the system or human resources, the present invention provides a mixture of directory search services used by the first generation search engine.

However, a search result screen using a directory search expression or a query input expression is merely a simple list of a number of related websites or web documents based on accuracy or popularity. Therefore, the user has to click the website or web document displayed on the search result screen provided in the search site and search for the desired information, so that the user has to take the hassle and inconvenience of time and effort.

In addition, the web document collected by the search robot collects URLs linked to the seed URL manually input by the administrator of the search site. Therefore, the web document collected by the search robot depends on the amount of seed URL input by the administrator. The amount is determined. However, since the seed URL of the current search site is a method of relying on the manual work of the administrator, it does not sufficiently reflect the exponentially increasing website.

The existing simple search method based on the number of keyword matching is based on the number of times the query appears in the searched document. As the amount of searched documents increases, more search results are provided and the documents that are important to the user are searched. It was difficult to screen. In order to measure the importance of a specific document, a method of measuring the number of times a user clicks on a result, etc. is used. The document dereference based method measures the importance of the document by giving a higher weight to the document with a lot of dereference, and gives a high weight to the keywords used as the title when referencing the link. How to calculate importance.

The method of using the dereference information between documents has a limitation in that it does not directly reflect users' preference for information by measuring the value of information by the mutual link between documents. In particular, the dereference information between documents is difficult to reflect the tendency of the dynamic user's dynamic information due to the static information characteristics.

The method of measuring the number of clicks on the search results is meaningful in terms of measuring the user's response to the information. However, since the measurement targets only the search results, various kinds of information and searches that the search system does not directly index. There is a limitation that it is impossible to measure the information preference about the case of visiting the URL directly without using the system.

In addition, search robots collect URLs linked to seed URLs, which are almost exclusively limited to existing websites or webpages, which are associated with communities such as clubs, fan clubs, games, chat, and search. It has a disadvantage that it is impossible for web robots to efficiently collect bulletin board related URLs, media file related URLs, and newly created websites or web pages.

In order to solve the above-mentioned problems, the present invention stores and analyzes URL log information that users visit or visits in an information service or information retrieval service using a wired / wireless internet to measure and grasp information preferences of users, and to grasp the identified information preferences. The present invention aims to provide a method and system for providing an information service and an information retrieval service by applying the information to a retrieval algorithm to improve the unit, coverage, and accuracy of information.

In addition, the user visited the UAL log to measure the association between the query, the association between the query and the UEL, the association between the UEL and the combination of these combinations, and the query that was not possible in the simple keyword matching method search using the measured information. Alternatively, the present invention aims to provide a method and system for identifying associations between specific UELs and recommending query and UEL information or a combination thereof.

It analyzes the preference information such as and stores in the preference information DB (254).

Here, the visit URL is URL information visited by each user, and the visit URL weight is information about a change in the number of visits, a total number of visits, a stay time during a visit, a visit date, and the like, for each URL visited. In addition, the preferred keyword is a keyword having a high order of appearance according to the frequency of occurrence of a query input or selected by each user while using the search service, and the preferred keyword weight is information about a change in the appearance frequency over a predetermined period of time for each preferred keyword. to be. In addition, a preferred word (Key Word) is a keyword that has a high ranking frequency for each keyword by categorizing the keyword that is input or selected while the user uses the search service and keywords representing the web pages visited. Similar to the preferred keyword weight, the keyword weight is information on the frequency of increase and decrease of the frequency of appearance for each period of time.

In addition, the preference information analysis module 244 analyzes an association relationship between the inputted query history, URL information visited after entering a query, and other URL information visited after a specific URL visit using the stored user information usage pattern log information. Make it applicable. That is, the preference information analysis module 244 uses the query history input by the user to correlate the relation between (query-query), the relation between (query-URL) through URL analysis visited after inputting the query, or (URL- It is also possible to analyze the correlation between the query terms) and (URL-URL) using the visited URL history after a specific URL visit. Such information may be extracted through the method described in the keyword / URL association information generation module 145 described with reference to FIG. 1.

Specifically, the association between (query-query), (query-URL), (URL-query), and (URL-URL) can be identified by identifying the co-occurrence between two elements and using them as the correlation calculation data. Can be. The relationship between these two factors is called Mutual Information, Kullback-Leibler Divergence, Cosine Coefficient, Entropy, Vector Space Model, and Probabilistic Model. It can be calculated using various calculation techniques such as Since the above-described degree of association algorithm is well known to those skilled in the art, a detailed description thereof will be omitted.

In more detail, each association is estimated by collecting a set of query pairs input by users. For example, if the query pairs inputted by a user are (Dae Jang Geum, Lee Young Ae) and (Dae Jang Geum, Ji Seong Hee), Dae Jang Geum is determined to be related to Lee Yeong Ae, Seismi Hee, and Lee Yeong Ae and Seismo Hee.

(Query-URL) association is estimated using the URL history visited by users after entering a specific query. For example, the (Question-URL) history of User 1 is (Dae Jang Geum, www.imbc.com/broad/tv/drama/daejanggum), (Lee Young Ae, www.imbc.com/broad/tv/drama/daejanggum '), ( Dae Jang Geum, www.leeyoungae.net) and (Lee Young Ae, www.leeyoungae.net) and User 2's (Question-URL) history is (Dae Jang Geum, www.imbc, com / broad / tv / drama / daejanggum), (Ji Jin Hee) , www.imbc.com/broad/tv/drama/daejanggum), (Dae Jang Geum, www.jinhee.sidus.net) and (Ji Jin Hee, www.jinhee.sidus.net). Analyzing (Query-URL) of User 1 and User 2 allows the calculation of the URL and weight associated with the query "Dae Jang Geum". In other words, the URLs associated with "Dae Jang Geum" are www.imbc.com/broad/tv/drama/daejanggum, www.leeyoungae.net, and www.jinhee.sidus.net. The number of selections may be set to 2, 1, and 1.

Finally, the correlation between (URL-URL) is estimated using the URL history input after users visit a specific URL. For example, User 1's (URL-URL) history is (www.imbc.com/broad/tv/drama/daejanggum, www.leeyoungae.net), and User 2's (URL-URL) history is (www.imbc. com / broad / tv / drama / daejanggum, www.jinhee.sidus.net), the URLs associated with www.imbc.com/broad/tv/drama/daejanggum are www.leeyoungae.net and www.jinhee.sidus becomes .net Of course, an association weight between the URLs may be set according to the number of inputs of the input URLs.

According to an embodiment of the present invention, the correlation between the query terms and the URLs is applied to an information retrieval service, thereby improving retrieval accuracy and providing a user-friendly retrieval service. First, by using the (query-query) association, it is possible to recommend a plurality of queries related to a specific query inputted to a user, and to provide a search result by extending the search target to a plurality of related queries. can do. (Query-URL) association can improve the search accuracy by providing a list of URLs visited by users who have entered the same query among the search results of a specific query entered, and actually visits because they use the actual URL visited. The searched URL may be searched even if the URL does not include content that matches the input query.

In addition, the (URL-query) association can be used to provide which query a user is visiting for a particular URL. This can be used as a keyword concept related to a specific URL, and can be used in selecting a representative keyword for a specific URL and searching for an associated collapse.

Finally, the (URL-URL) association allows the user to recommend a URL that is related to a specific URL selected by the user, and provides a service by clustering similar URLs. In this case, when a user visits a specific URL, an information recommendation service that automatically recommends a URL that is visited statistically by people who visited the specific URL without a user's additional action such as inputting a special query is possible.

The custom information generation module 246 generates optimal customized information for each user in cooperation with the preference information analyzed by the preference information analysis module 244 and the search module 262 and the topic-specific information generation module 264 to be described later. Perform the function. The custom information generation module 246 may generate and provide custom information when a query is input from a user, but check the preference information identified for each user and push update information when an update of the corresponding preference information is detected. May be provided in real time using the

The search server 260 includes a search module 262 and a topic-specific information generation module 264 that perform functions similar to those described in FIG. 1. In particular, the search module 262 performs a search using the query word received from the web server 240, and the user-specific information use pattern log information stored in the pattern log DB 252 and the preference information DB 254; The preference information is used, and the search result is provided to the custom information generation module 246.

Meanwhile, in the search service using the user information usage pattern log information described with reference to FIG. 2, personal information of the user information may be used to identify preference information for each group, and personalized search information for each group using the identified group preference information. Can be generated and provided. The group-specific customized search information service may be provided based on a procedure of querying whether the user approves the use of the user's personal information and obtaining a response at the registration stage of the search service server 230, or the user is not logged in. It can also be provided by specifying only the group to which it belongs in the login state.
