探讨Ontology的信息检索策略

针对现有的基于关键字的传统检索方式存在着检索精度不高的问题，提出了将Ontology融合到信息检索技术中的思想，利用领域Ontology里的概念、关系，建立了基于Ontology的海洋文献检索模型，并通过PaperSearch检索系统验证了策略的优势。

Study on Ontology-based Information Retrieval Strategy

The traditional information retrieval based on keywords can not meet people's demands for information because of its low precise.To solving this problem,we adopted domain Ontology in our information retrieval system.By using of the con-cept and the relations in Ontology,an ontologybased information retrieval model about ocean literature is proposed,and the strategy is proved advanced with PaperSearch information retrieval system.
