摘　　要：基于本体的语义检索是提高信息系统检索精确度的有效途径之一。概念云是云模型在信息领域的应用,是本体中的概念按照一定算法在页面中的排列聚合。基于本体与概念云来构建信息检索系统,其设计方案是采用自上而下与自下而上的两种方式相结合构造全局本体、局部上层本体、局部下层本体;再使用Web2.0环境下的内容管理工具进行本体中概念的管理与组织,从而形成概念云;最后以本体与概念云来完善信息检索系统,既提高检准率,又满足用户对知识获取的需求,并可为其他本体系统构建者提供对概念的获取与重用用户知识的功能。本文还描述了本系统语义检索功能实现的原理,阐述了该系统基本实现步骤和关键细节,并展示了该系统的部分功能。Semantic retrieval based on ontology can improve the accuracy of information system retrieval effective.As an application of cloud model in the domain of information science,concept cloud comes from the ranking and aggregation of ontology concepts according to certain algorithm.This paper introduces the design and realization of Information Retrieval System Based on Concept Cloud and Ontology（IRSCCO）.First,a hybrid approach combining the＂top-down＂and＂bottom-up＂methods is introduced to build global ontology,local upper ontology and local lower ontology.Then,content management tools are used to manage and organize ontology concepts and thus form concept clouds.Finally,ontology and concept cloud are applied to better the information retrieval system not only to improve retrieval accuracy but also help users on knowledge acquisitions and provide concept acquisition and user knowledge reuse functions to other ontology system constructors.Moreover,semantic retrieval realization principles,the basic realization steps and key technologies of IRSCCO are elaborated on and part functions of the system are demonstrated.
