Integrated session environment-oriented information recommendation method

Abstract

The invention discloses an integrated session environment-oriented information recommendation method. In the method, a real-time active information acquiring technique is adopted and the method comprises the following steps of: during the session, actively perceiving specific topics in the current session; judging the change of the topics; automatically generating index words to retrieve under the condition that the topic changes; and presenting the search results to users. At the same time, the method integrates the characteristics of continuous change and flow of the integrated session environment information; the topic of a speech text is analyzed by adopting the method of the combination of field characteristics and the common characteristics, and the screening of important information is realized through the coordination of a plurality of users so that the information recommendation is realized. The method, which is tested in the integrated session environment, can be applied in the environments such as instant communication, network meeting and the like, so that the information searching cost is greatly reduced and the information use ratio is effectively increased.

Description

technical field [0001] The invention relates to a method for recommending information to users according to the content of the discussion in a comprehensive integrated discussion environment, in particular to a method for real-time extraction, tracking and collaborative filtering of discussion topics and its realization. Background technique [0002] A comprehensive integrated discussion environment [1] is an online discussion environment where multiple users discuss in text form based on a specific field. Users who participate in the seminar speak and discuss a pre-determined topic, and finally use the discussion results to solve a series of complex problems. [0003] With the development of information technology, the resources on the network are increasing explosively, making the Internet one of the main media for information dissemination. And a large amount of information on the Internet, especially authoritative webpages about a certain issue, is of great significance...

Problems solved by technology

[0005] In a comprehensive and integrated research environment, information such as browsing history and behavior patterns of users participating in the research cannot be obtained, so it is not feasible to mine the data requirements of user interests through the above information modeling; at the same time, in a comprehensive and integrated research environment, multiple users act as a There is a certain time pressure for groups to work together, and the amount of information directly searched from the Internet is large and the degree of relevance to the topic cannot be determined. It needs to be screened according to the content of the current discussion and through collaborative recommendations between multiple users Information that is more relevant to the discussion topic and then recommended to users

Therefore, the existing network user-based information recommendation system cannot meet the needs of a comprehensive and integrated discussion environment
