提出一种利用概念格发现领域关键词间的语义关系的方法,定义了关键词间两种语义关系:相似关系和蕴含关系;关键词根据其出现频率高低分为高频关键词、中频关键词,低频关键词,进而形成关键词的语义空间.为发现高层次主题间语义关系提供了条件,也为形成语义网络奠定了一定的基础.在上海某服装搜索引擎项目中取得了很好的效果,可以直接应用于搜索引擎中的相关搜索和关键词扩展.

A method to find the semantic relationship among domain keywords based on concept lattice is proposed, and two semantic relationships: Similar relationship and imply relationship are defined. According to the frequency of the keyword occurring in the text, keywords are classified as high-frequency keywords, middle-frequency keywords, and low-frequency keywords. It forms the semantic space of keywords, providing the condition to find the semantic relationships in the topic level and form the semantic network. Good result is obtained in the search engine about clothes in Shanghai, and can be directly applied to related search and keyword extending.
