摘　　要：给出一种基于本体与刻面的资源描述与检索系统的设计与实现。充分发挥基于刻面的描述与检索方案准确、高效的优势,在此基础上引入本体,利用本体知识中蕴含的丰富关系,弥补基于刻面的资源描述与检索方案中术语、刻面之间关系匮乏的缺点,大大提高检索的查准率与查全率。介绍了从本体的设计、编码、入库到基于本体的检索条件预处理,最后检索引擎执行检索的设计与实现。The design and realization of a resource description and retrieval system based on ontology and facet is presented. This system exploits the advantages of accuracy and efficiency of resource description and retrieval system, and on this ground, ontology is introduced to cover the shortage of relations deficiency between terms and facets. Thus, the retrieval accuracy is improved. The design, coding and loading of ontology, the retrieval qualifications preprocessing, and the retrieval procedure are described.
