摘要 提出一个基于二元语义的信息检索模型。该模型包含文档的表示、查询语句的表示、文档和查询的匹配3个部分。相对于传统的基于查询关键词精确匹配的信息检索模型,该模型能较好地满足用户查询要求中的灵活性。 This paper proposes, a 2 - tuple linguistic model of information retrieval. The model has three components : the documents, the query and the retrieval mechanism. With respect to other information retrieval model based on precise retrieval, this model can give users more flexibility when they retrieve their desired documents.
