Behavior-Based Domain Information Retrieval Method

Abstract

The invention provides a field information retrieval method based on behaviors. The information retrieval method based on the behaviors can achieve optimization by means of department subordination relations of users and various interdependent user behaviors. The information retrieval method based on the behaviors includes the following steps that firstly, the department subordination relations of system users are obtained through analysis of an department subordination relations, namely which users belong to which departments, and activities performed in the process that the users use the information management system; secondly, the similarity degree of information is calculated through behavior data; thirdly, full-text retrieval is conducted on search terms inputted by the users, matching contents are obtained to the maximum to obtain full text matching results; fourthly, the full-text retrieval is filtered, the results are ranked according to interest reflected by the user behaviors, and the contents which the users are most interested in are ranked to the headmost position.

Description

technical field [0001] The invention relates to an information retrieval method, in particular to a behavior-based domain information retrieval method. Background technique [0002] At present, knowledge management system is widely used in enterprises as a platform for enterprise knowledge accumulation and reuse. Retrieval technology is an important functional module in knowledge management system. Effective information retrieval function can help system users find the required enterprise knowledge quickly and accurately. Existing searches often use keyword matching technology. The problem brought by this technology is that no matter who the user is or when the user uses the system, as long as the same keyword is input, the same search result can always be obtained. The obvious shortcoming of this retrieval method is that it ignores the different information needs of different users and the changing information needs of the same user. The problem to be solved by the presen...

Problems solved by technology

This method obtains the user's interest by analyzing the logs or behaviors collected by the system, but this method generally only relies on the information of what content the user has accessed and when

This method is suitable for general website user interest analysis, but it cannot fully meet the needs of information systems implemented in enterprises.

First of all, the departmental affiliation relationship between users in the enterprise expresses their similar interests to a certain extent. In addition, the behavior information that can be collected in this information management system is also richer. The existing behavior-based methods are not Ability to use a variety of behavioral information to analyze user interests
