摘要 在分析基于搜索引擎的术语相似度算法基础上,设计并实现了基于领域限定网络检索的术语相似度算法,通过将语义上下文和领域上下文引入检索式构造过程,有效提升了特定领域术语相似度计算效果。 Based on the analysis of the term similarity algorithm based on search engine,this paper designs and fulfils the term similarity algorithm based on domain-restricted Web search.By introducing the semantic context and domain context into the construction process of retrieval formula,the computing result of the term similarity in specific domain is effectively improved.
