Application of Dynamic Manifold Method in Multi Document Summarization Model
摘要
Abstract
The identification and analysis of evolutionary information on the internet is an efficient means to get useful information,which has become a critic issue urgent to work out.Based on time information,starting from network dynamic evolution,the dynamic multi document summarization analyzes the document sets of different period about a same topic.On the basis of identifying the difference of information content,a summarization model can be built.Based on the classic manifold ranking model,we propose a dynamic manifold ranking model which not only adds some significant features,but also introduces some historical redundancy features and some time infor-mation feature,which make the information contained by abstract dynamic.An evaluation based on this model is conducted on the update task corpus of TAXT ANYNASIS CONFERENCE 2008 and a good testing result is obtained.关键词
