摘　　要：区别于传统的测绘图书检索以关键词进行匹配和查询的机制,提出在测绘图书检索中加入语义技术,通过构建测绘信息本体库及针对图书资料数据存在着数据源异构问题构建本体映射模型来处理检索请求,基于Oracle 11g语义技术设计并实现测绘学科图书语义检索原型系统,以武汉大学图书馆信息科学分馆图书数据为检索对象进行检索实验,结果表明该方法可提高检索的查准性和查全性。Different from traditional surveying and mapping retrieval keyword matching and query mechanism ,a re-trieval method of surveying and mapping books based on ontology is proposed , through the construction of surveying and mapping information ontology and ontology mapping model according to the heterogeneous data source of books to deal with the retrieval request ,the semantic retrieval system of the surveying and mapping books based on the oracle 11g semantic techniques is designed and implemented and also book＆#39;s retrieve which about the Information Technology Library of Wuhan University Library are tested ,the results show that the method can improve the retrieval precision and comprehensive .
