Generation of stage summarization for news special topic
摘要
Abstract
Stage summarization for news special topic could provide more reference information for investigating the dynamic evolution and drawing the development outline about the topic,and to some extent it could overcome the drawback that there were so many topic-related reports which were inconvenient to browse for readers.Taking “Missing Malaysia Airlines flight MH370”as an example,this paper discussed an algorithm for stage summarization generated from news special topic.After the first step of subject extraction for each news text,it converted the stage document set to its corresponding subject set.Then it put forward bidirectional cluster method based on time stream to find diverse topics in the latter set and used the intersections between bidirectional categories to cluster again to obtain some important information.Finally it chose those subjects according to all cluster results to constitute the stage summarization.Contrast experiments show that the algorithm receives better Rouge recall rate.关键词
