Dynamic Multi-Document Summarization Research based on Matrix Subspace Analysis Model

Abstract

In this paper, we described dynamic evolution of network information, as well as identify and analysis the document collection on the same topic in different stages. Dynamic summarization considers the different documents\u2019 temporal relationship in multi-document and analyzes the relationship between emerged information and emerging information. In order to construct a dynamic evolution of content differences, a dynamic multi-document summarization model was presented, called the Matrix Subspace Analysis Method model. On this basis, proposed some efficient dynamic sentence weighting methods, and experiments on the test data of Update Summarization in TAC2008, we showed effectiveness results.
