The present invention relates to the retrieval and provision of information, and more particularly, to a method and apparatus for extracting and providing issue data related to a user's interest.

Personalized service refers to a service that provides personalized content according to the user's personal information. For example, a personalized service analyzes an individual's use of the Internet and forms an initialization screen with information optimized for each individual, or for each member's content. The service may be categorized and the screen may be configured according to the content mainly used by each individual. In addition, another example of the personalization service may be a service that allows a user to communicate on behalf of a user or substitute for my role through an alter ego such as an avatar.

As such, there has been a method of providing a personalized service for providing personalized information for each individual, but it is cumbersome because each user has to set it individually, and there is a limit in receiving various contents according to the interests of the individual due to the lack of contents.

Accordingly, the technical problem to be achieved by the present invention is to provide an information providing method and system for extracting an issue reflecting an individual's interest and providing it to a user.

According to an aspect of the present invention, there is provided a method including receiving location information of a server storing a search word entered by a user or information selected by the user; Accessing a web site corresponding to the location information and extracting a keyword list having a frequency of occurrence of words included in the content data of the predetermined number or more; Generating a list of interests by referring to the number of inputs of the search word and by referring to the key word list; And storing the generated interest list.

The information providing method includes the steps of receiving user identification information; And identifying the interests of the user by referring to the identification information of the user, and extracting and providing an issue related to the interest with respect to issue data on the Internet extracted and stored according to a predetermined method. .

On the other hand, according to another field of the present invention, the technical problem is to receive a search word input by the user or location information of the server storing the information selected by the user, referring to the number of input of the search word and of the words constituting the selected information An interest manager configured to generate a list of interests by referring to the keyword list generated at the frequency of appearance; A key word extraction server that accesses a web site corresponding to the location information and extracts a key word list having a frequency of occurrence of a word included in the content data more than a predetermined number of times and delivers the key word list to the interest management unit; And an interest storage unit for storing the generated interest list.

The information providing system includes: an issue storage unit for storing issue data on the Internet extracted according to a predetermined method; And an interest processor which receives the identification information of the user, reads an interest corresponding to the identification information from the interest storage unit, and reads and provides issue data related to the interest from the issue storage unit. .

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of an information providing system according to a preferred embodiment of the present invention.

The information providing system includes an interest management unit 120, a keyword extraction server 130, and an interest storage unit 140. Further, the interest processor 150 and the issue storage unit 160 may be further provided to provide a personalized issue according to the user information received from the user PC 110 (for example, using a cookie or a temp file as the user identification information). Include.

The interest management unit 120 receives a search word from the user or location information of information to be read by the user, refers to the number of inputs of the search word, and generates a key word list made according to the frequency of occurrence of words constituting the information to be read by the user. Create a list of interests by reference. The keyword extraction server 130 refers to the above-described location information, accesses a web site corresponding thereto, extracts a keyword list whose frequency of occurrence of words included in the content data is a predetermined number or more, and transmits the keyword list to the interest management unit 120. . The interest processor 150 receives the user's identification information, reads the interest corresponding to the identification information from the interest storage 140, and reads the issue data related to the interest from the issue storage 160 to the user. to provide. Hereinafter, the operation of each component will be described in more detail.

A user accesses a search site through the user PC 110, enters a search word, clicks a search result or a link to read data stored in the search site, or reads data stored in another site other than the search site. Click on the site's Uniform Resource Locator. Therefore, the URL becomes location information of information that the user wants to read. The input search word or clicked URL information is transmitted to the interest management unit 120. The interest manager 120 transmits the input URL information to the keyword extraction server 130. The keyword extraction server 130 accesses the corresponding web site according to the received URL information, reads the content, and extracts the keyword. Extraction of the key word can be performed according to various methods. For example, a word that appears more than a certain number of words frequently appearing can be extracted as a key word, but a key word can be extracted by weighting words appearing in the title. The weight may be, for example, a value between 0 and 1. The key word list composed of the extracted key words is transferred to the interest management unit 120.

The interest manager 120 generates an interest list by referring to the input search word and the received keyword list. The list of interests can be in the form of a database of, for example, (keywords, importance values). For example, if the search term "first snow" is entered twice and the word "first snow" appears 30 times in the contents obtained by clicking the URL, the weight of the search term is 0.8 and the content is 0.2. , The interest of "first sight" is 2x0.8 + 30x0.2 = 7.6. In this way, a list of interests is created for each interest, for example:

(First Snow, 7.6), (NeoWiz, 4.3), (Ulzzangsa, 3.0), (Naver, 2.2), (Juraim, 5.0) ...

The interest list thus created is transferred to and stored in the interest storage 140.

Meanwhile, the issue information that the user is interested in is extracted by the interest processor 150. First, user identification information is received from the user PC 110. The user identification information can be entered, for example, by sending a cookie stored in the user PC 110 or by sending a temporary internet file. The interest processing unit 150 receives user identification information, extracts the issue from the issue storage unit 160 by reading the interest of the user from the interest storage unit 140 and reflecting the interest. The issue storage unit 160 stores issues in all fields, and the issue extraction may be performed according to various conventional methods. For example, all data on the Internet are listed in the order of the document title and their frequency of appearance, and documents with a frequency below a certain value are deleted. Then, the documents obtained in this way can be selected as an issue, and the issues can be selected from several documents in the order of date (most recent date). However, in determining the issue, various criteria may be used, such as the frequency of occurrence, other date of creation of the criterion, the inclusion of images, and the length of words.

2 is a flowchart of a method of storing interests according to a preferred embodiment of the present invention.

In operation S210, a search word from a user or location information of information to be read by the user is input. The location information may be URL information. The keyword list is extracted by accessing the corresponding web site with reference to the URL information and the occurrence frequency of the words included in the content data of the predetermined number or more (S220). The key word can be extracted according to various methods as described above. For example, a word that appears more than a certain number of words that frequently appear can be extracted as a key word but weighted to words appearing in the title. have.

Next, a list of interests is generated by referring to the number of occurrences of the extracted core word and the number of inputs of the search word input in step S210 (S230). A list of interests can be created like (interest, importance value). In calculating the importance, the importance may be calculated by combining the number of occurrences of a keyword and the number of inputs of a search word, but the importance may be calculated by giving more weight to the number of inputs of a search word. The interest list generated in this way is stored in the interest storage unit 140 (S240).

3 is a flowchart of a method of extracting an issue reflecting an interest.

Receive user identification information from the user (S310). Receipt of the user identification information may be received through, for example, a cookie file of the user PC. The user's interest corresponding to the received user identification information is read, and an issue related thereto is extracted (S320). For example, if the first concern of interest corresponding to the user identification information is "soccer", the issue corresponding to "soccer" is extracted from various subjects. The extracted issue is provided to the user (S330).

4A to 4B are diagrams illustrating an example of a connection between an information providing system and a user.

As shown in FIG. 4A, the user PC 410 and the information providing system 411 may be connected in a 1: 1 manner, and may be connected in a 1: n manner as shown in FIG. 4B. Multiple user PCs 420-422 can share a common interest when connected 1: n. In this case, the user PCs 420 to 422 provide the same user identification information to the information providing system 425. For example, people working on the same project within a company may share the same interests.

Since the same user identification information can be transmitted to share interests, the user may be provided with the same issue information at work or home without setting on the user's PC.

On the other hand, the above-described information providing method can be created by a computer program. Codes and code segments constituting the program can be easily inferred by a computer programmer in the art. The program is also stored in a computer readable media, and read and executed by a computer to implement the information providing method. The information storage medium includes a magnetic recording medium, an optical recording medium, and a carrier wave medium.

So far I looked at the center of the preferred embodiment for the present invention. Those skilled in the art will appreciate that the present invention can be implemented in a modified form without departing from the essential features of the present invention. Therefore, the disclosed embodiments should be considered in descriptive sense only and not for purposes of limitation. The scope of the present invention is shown in the claims rather than the foregoing description, and all differences within the scope will be construed as being included in the present invention.

As described above, according to the present invention, there is an effect that the user can be provided with personalized issue information reflecting the interests of the individual without setting his or her personal information.
