中文摘要: 针对传统基于内容相似度的事件关系计算方法不能分析出事件间的潜在关系的问题，提出了基于FCA 的事件关系计算方法。该方法利用根据话题的三层结构模型，对话题中的事件进行属性提取，并依据特征频率因子进行属性选择。利用两个事件之间的属性关系建立形式背景，以此为基础形成概念格。用基于概念格的相似度分析发现事件之间潜在。实验证明了这种方法的有效性。
Abstract:Traditional event evolution analysis method can’t find out the relationship between potential connected events in a topic. We proposed a new method based on FCA. This method uses the idea of topic three layer model to extract the properties in the event and filter the useless properties in the light of PFF(Property Frequency Factor ). It constructs the Formal Context with property relation between events and analyzes the event evolution relation with similarities algorithm based on concept lattice. Practical examples show our method is effective.
