AI Technical Summary

Problems solved by technology

Because the biased summary is usually only generated according to the query conditions, and the query conditions often cannot accurately express the user's query intention; on the other hand, the biased summary content does not consider the user's interest difference, as long as the query content is the same, the summary content is the same, and it is difficult to satisfy different users. needs

Embodiment

[0074] Assume that there are three users who are farming, cooking and nutrition experts. Due to their different interests, the three users pay attention to different news on the Internet, which can be easily reflected from the users' browsing content. Web documents build user interest models. User model for three users see Figure 4A , Figure 4B , Figure 4C As shown in the figure, when experts in breeding, cooking and nutrition enter "beef" in the retrieval system with a personalized abstract unit for query, although the three users retrieved the following article about "beef" at the same time articles, but due to the different interest models among users, the summary content presented to users is different.

[0075] According to the retrieval logs of the three users of breeding, cooking and nutrition experts, this method is used to establish such Figure 4A , Figure 4B , Figure 4C The user interest model shown. Among them, the interest model of breeding experts inc...

Abstract

The invention discloses an individual abstract system based on user interest modules. The individual abstract system consists of a Web information retrieval unit, a user interest unit and an individual abstract unit. In the individual abstract system, the user interest modules described with hierarchical conceptual structure are established and/or updated by using the conceptual clustering method through analyzing retrieval logs of users; subsequently, the similarity of user interests and sentences in the retrieval results is analyzed according to the user interest modules and the retrieval results, thus getting individual abstracts meeting requirements of users. The individual abstracts got through grading and handling individual sentences takes full consideration of the interests and the features of users so that the generative process of the abstracts are matched according to the interests of users and improving the effectiveness of the abstracts and the satisfaction of users.

Description

technical field [0001] The present invention relates to an information retrieval method in the Internet, more particularly, refers to a personalized summary system that uses concept clustering to establish and / or update a user interest model described in a hierarchical concept structure by analyzing user retrieval logs. Background technique [0002] Search engines are an important tool for people to use Internet resources at present. Users submit queries according to their own retrieval intentions, and then get a large number of retrieval results. It is impossible for users to read all the content of each result, so the search results are often given in the form of abstracts for users to choose the content they are interested in. [0003] Traditionally, summaries are in the form of query-biased summaries. A biased summary is a focused summary generated according to the user's query requirements. Because the biased summary is usually only generated according to the query co...
