Abstract:Based on the characteristics of special news text sets,the paper extracts and preprocesses some keywords of news texts. Then texts are represented with the Vector Space Model and clustered by K means algorithm. Then the authors construct a relevance network of keywords in accordance with the processed keywords to realize the information visualization of special news text sets. An example shows that the presented approach can not only show the information and highlight the relationship between news texts but also facilitate the rapid grasp of main subjects and events and the changes of the focus as time changes, so as to enhance the understanding of information and make full use of it.
Keywords:information visualization  text information  relevance network
