摘要 为了满足用户的个性化需求,提供尽可能丰富、实用、方便的文摘结果,该文设计了面向查询的多文档自动文摘的多种摘要模式。在将查询返回的文档集合表示为以文本、段落为节点的双层复杂网络结构以发现子主题的基础上,除传统的摘要模式外,该文又设计了概括摘要、局部摘要、全局摘要和详细摘要这四种摘要模式,并给出了各种摘要的生成方法。支持用户以主题为线索自主漫游,按照一定的逻辑顺序浏览信息。 In this paper,we design a variety of summary modes for Query-directed Multi-document Summarization to satisfy the individual requirements by diversified results.Firstly,the documents are represented as two-layer complex networks,whose nodes describe text and paragraph respectively,and the network community discovery algorithm is used to cluster text and paragraph.Then,on the basis of network structure of documents,we design four summary modes besides the traditional summary mode and summary element extract strategy.They are document summary,general summary,partial summary,global summary and detailed summary.With the clues of sub topic,users can browse information in certain logical sequence to their own.
