Concept space navigation method based on concept association

Abstract

The invention provides a concept space navigation method based on concept association. The method includes the following steps that 1, a user selects a certain concept C as an initial concept for navigation; 2, the similarity between the concept C and other concepts in concept space are calculated, and similarity old values (if exist) are updated; 3, semantic association information {<C, related concepts, association types >} of the concept C is acquired; 4, two indexes of the similarity value between each of the other concepts and the concept C and existence of semantic association are integrated and standardized; 5, according to the two indexes in the step 4, the correlation degree value of each of the other concepts and the concept C is calculated, the values are ranked from large to small hereby, and Top K concepts are taken; 6, the K concepts and the similarity values and semantic association information of the K concepts and the concept C are displayed visually through a concept map; 7, the user finds the target concept, and navigation is completed; or the concept needing to be further extended (explored) is selected, and the steps are repeated. The designated concept is navigated to association concept groups thereof, the user can conveniently find the target concept, and the retrieval efficiency is improved.

Description

technical field [0001] The present invention relates to the organization, query and retrieval technology of personal information management, in particular to a concept map expression form of concept space and a concept navigation method based on concept association. Background technique [0002] Personal information management involves the practice and research activities that people carry out in order to obtain, organize, maintain and retrieve information for daily use, including methods and rules for obtaining personal information, mechanisms for organizing and storing information, rules and processes for maintaining systems , Retrieval mechanism. However, with the rapid development of modern information technology, the crisis caused by the information explosion is increasingly affecting personal information management, which brings great difficulties to maintaining and accessing the required information. A large amount of information is piled up in the form of electronic...

Problems solved by technology

The disadvantage of this type of retrieval method is that the returned result set is large, the precision rate is relatively low, and the user still has to undertake a lot of information screening work. At the same time, the semantic connection contained in personal information is ignored.
