基于本体的资源描述和检索方法研究

Research on Ontology-based Representation and Retrieval of Resources

计算机和网络技术的飞速发展使得网络日益成为资源获取的重要来源。网络资源由于其数量具大、多元化等特点,使得资源的组织管理更加复杂。资源的描述和检索是其中的主要问题。基于目录分类、关键字等的资源描述方法缺乏语义信息,因此无法较好地满足用户的检索请求。文章针对这一问题,引入领域本体作为资源描述的知识基础,以刻面作为资源描述框架,从而更加智能地满足用户的资源检索请求。

The rapid development of computer and network makes Internet resource more and more important in our lives.Organization and management of Internet resource is much more complex than that of conventional resource due to the features of large quantity and variety.Representation and retrieval of resources is the main problem.Conventional representing and retrieving methods lack semantic information,so can not meet the resource requirements of users. Aiming at this,we introduce domain ontology and facets as the knowledge base and framework of resource representation respectively,Then the resource requirements of users can be met more intelligently.
