空间数据全文检索方法研究

摘要

全文检索是处理非结构化数据的强大工具,也是现代信息搜索引擎的核心技术之一.介绍全文检索技术,对其发展以及优缺点进行简单概括；继而在分析全文检索无法直接应用于空间数据搜索基础上,提出一种基于地理编码的空间数据全文检索方法；最后应用Oracle Text结合ArcEngine空间数据引擎对该方法进行实验,验证方法的正确性和可靠性.%It presents the concept and developing situation of full-text retrieval technology, and the related search engine mechanism. Based on full-text retrieval technology and geocoding technology, a new retrieval method of spatial data is proposed. Finally, an Oracle Text combined with the spatial data of ArcEngine is adopted to validate the correctness and reliability of this method.
