基于概念云与本体的信息检索系统（IRSCCO）的设计与实现

Semantic retrieval based on ontology can improve the accuracy of information system retrieval efficiently. 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. In this paper, we put forward a design scheme of information retrieval system based on ontology and concept cloud, account for the principle on semantic retrieval realization and elaborate on the basic realization steps and key technologies. Moreover, part functions of the system are also demonstrated.
