Description

Method for providing content based on user profile

The present invention relates to a method and system for providing content based on a user, and more particularly, based on a keyword extracted by excluding a non-information keyword from a content accessed by a user and content accessed by the user. The present invention relates to a method of generating a user profile in real time according to similarity or association and providing user-based content according to the generated user profile.

As digital broadcasting is spreading over time since the digital broadcasting starts in earnest, the number of channels and programs that users can watch is exploding. In the existing TV system, the number of programs was limited to a small number, so the range of program selection was narrow. Therefore, the user could search a desired program without a great difficulty among a limited number of programs.

However, as the number of channels and programs provided to the user in the digital broadcasting system reaches hundreds and the number of channels and programs is expected to continue, the user can search the remote control operation or the broadcasting schedule to watch the desired channel or program. shall. Therefore, in the reality that the number of channels and programs is greatly increasing, a problem arises in that a lot of time and effort must be wasted to search for a desired channel or program.

Due to this problem, there is a need for a method for analyzing a user's profile and preference information and recommending a program that matches a user's taste or interest. As part of this demand, a personalized Elotronic Program Guide (PEPG) is proposed. There is an active research on. The personalized broadcasting schedule is a technology that selects programs suitable for the user's taste by using filtering techniques and provides them to the user. The content-based recommendation technique compares the similarity between the user's interest and the content with the recommendation technique. There is a Collaborative Recommendation technique that recommends content of interest among users with similar interests. These recommendation techniques are all based on a user profile that describes the taste of the user. Therefore, in order to increase the quality of the recommendation information, it is very important to create a more accurate user profile.

The user profile creation method is an explicit method of inferring a user profile by using personal information or interest information provided directly by the user, and an implicit method of inferring a user profile through user behavior. Can be classified. The explicit profile generation method can infer a user profile quickly and accurately, but has a problem in that it is difficult to reflect a dynamic change in user's taste that is cumbersome and changes in real time because the user must directly input user information or interest information.

On the other hand, the implicit profile generation method reflects the dynamic profile of the user who changes in real time by inferring user interest information and taste by identifying characteristics of the content used by the user instead of directly inputting personal information or interests of the user. can do. However, the generation of the implicit profile is performed independently in each content providing server used by the user, and therefore, it is difficult to implicitly create the user profile in the content providing server which the user does not frequently access.

In addition, since the implicit user profile generation method performed in the conventional content providing server is based on the generation of the user profile of all the content accessed by the user, the content that is not a real interest of the user is based on the creation of the user profile with the same weight. The problem is that the user profile is not created correctly.

Furthermore, most web content has a common layout recently (especially for dynamically generated web content, which is more common), and many factors that are not very relevant to the user's interest (logo). , Move buttons, ads, copyright notices, etc.). As described above, all of the elements that have nothing to do with the user's interest are considered to be difficult to accurately generate the user profile. Hereinafter, elements that have nothing to do with the user's interest in the content are referred to as noncontent blocks.

The present invention is to solve the problems of the conventional user-based content providing method mentioned above, the object of the present invention is to achieve based on the access time of the content actually accessed by the user of the searched content according to the search word entered by the user By providing a user profile generation method that can accurately grasp the user's interests.

Another object of the present invention is to generate an accurate user profile from extracted keywords except for non-information blocks included in the content, and to provide a user-based content recommendation method based on the generated user profile.
