摘要/Abstract

摘要： 利用事件报道描述内容高度相似的特点,提出了一种抽取式话题简短表示生成方法。把事件文档标题集中的标题作为处理对象,从不同的标题中抽取出保留原有语序的共性信息,并进一步融合这些共性信息,生成事件粒度的话题简短表示。在来自搜索引擎中的事件数据上,实验结果表明该方法能生成精练、准确、语义明确完整且可读性好的话题简短表示。

关键词: 话题简短表示生成, 抽取式, 事件

Abstract: This paper takes advantage of the fact that event description contents are highly similar, and proposes an extractive topic brief representation generation method, which takes the titles in the event document set as the processing object, and extracts the common information retaining the original word order from different titles, further integrates these common information to generate a topic brief representation of the event. The experimental results on the event data from search engines show that this method can well generate the topic brief representation with concise and accurate form, clear and complete semantics and good readability.

Key words: topic brief representation generation, extractive, event
