摘要
为对突发事件的信息提供高质量的检索服务,分析了各种突发性事件报道的结果类别,介绍了各结果类型间可能拥有的包含关系及判断算法,提出了一种能对突发事件结果信息进行准确抽取的方法。该方法首先对突发事件文本按照预定义的规则进行匹配,其次对抽取出来的结果信息节点进行规范化处理,接着按照结果类型包含表,对结果信息节点进行包含关系判断,最后进行信息合并处理并以结构化的形式返回最终取结果。实验结果表明了该方法的有效性。
To provide high quality retrieval service of emergency event,result types of Chinese news event and the algorithm of inclusion relationship detection among the different result types are proposed. A method of extracting information of the emergency event is put forward. Firstly,the system will use the predefined rules to match every sentence of input files and normalizes the result information. Then,it will deal with the inclusion relationship of the result nodes and merge the result nodes. Finally,the structured output result is generated. The experiments show that methodologist and strategies are feasible.
