Embodiment Construction

[0040] The present invention will be further introduced below in conjunction with the accompanying drawings.

[0041] The invention proposes a domain knowledge browsing method based on a knowledge map, which can navigate users who are not familiar with the domain knowledge. The only input required by the method in the present invention is collected domain knowledge (the domain here mainly refers to the text type, and other types can be converted into descriptions in this paper through additional text information or marking methods), and the output is used for navigation domain knowledge map and a set of calculated important knowledge. The knowledge map here refers to a group of domain knowledge and the association between these knowledge, which is expressed by an undirected graph in mathematics in this invention, with figure 1An example of a knowledge map is given in . This example includes 10 domain knowledges, and some domain knowledges have semantic relationships, as show...

Abstract

The invention provides a domain knowledge browsing method based on a knowledge map, which can navigate users unfamiliar with the domain knowledge. The domain knowledge browsing method based on the knowledge map is divided into two stages comprising constructing the knowledge map and recognizing important knowledge, wherein three data objects exist in total, namely a domain knowledge library, a domain knowledge map and important knowledge; and the important knowledge is used for allowing a knowledge user to browse a starting point of a knowledge library, the domain knowledge map is used for navigating the knowledge user in a knowledge browsing process, and the domain knowledge library is used for providing a specific flow of knowledge. According to the domain knowledge browsing method based on the knowledge map, which is disclosed by the invention, information other than the domain knowledge library is not needed, and the knowledge map and the important knowledge can be generated in the domain knowledge library; and by utilizing a manner that the domain knowledge map is established by utilizing a latent semantic analysis technology, noise data in a domain can be largely removed, and the semantic connection characteristic of the domain knowledge map is better indicated.

Description

technical field [0001] The invention relates to a knowledge browsing method, in particular to a domain knowledge browsing method based on a knowledge map. Background technique [0002] The phenomenon of information overload refers to the phenomenon that information users cannot process (understand content or find interesting content) due to too much information provided to information users. This phenomenon exists widely in Internet information browsing. In order to improve information overload, there are currently two main methods used. One is to use the method of information visualization to make the presentation of information more intuitive, and the other is to use the method of monitoring user browsing behavior and making predictions. [0003] The information visualization method mainly uses text classification and clustering technology to automatically classify the content, and uses multi-dimensional scaling technology to map the classified information to two-dimensio...
