摘要： 为提高搜索引擎的语义处理能力，以旅游领域为背景，利用领域本体对知识的表示和推理能力，提出一种领域本体中基于概念格的相关度计算模型。根据该模型设计用户检索项推荐技术并予以实现。实验结果表明，相关度计算模型能充分利用本体中概念的语义信息以及实例之间的关系，得到的结果较合理。

Abstract: In order to improve the semantic processing capacity of search engines, taking tourism for example, this paper proposes a model based on ontology correlation concept lattice through the way of combining domain ontology for knowledge representation and reasoning with the concept lattice theory. A new user’s retrieve items recommendation technology is designed and implemented according to the model. Experimental results show that the correlation model uses completely the instances relations and the semantic concept of ontology and the rational results are achieved..

Key words: semantic relativity, domain ontology, concept lattice, information retrieval, user’s retrieve items recommendation
