基于本体的空间搜索引擎研究

Research on Geographic Search Engine Based on Ontology

提出了一种智能空间搜索引擎的解决方案。通过分析传统搜索引擎在处理空间语义方面的缺陷,将本体和自然语言处理技术引入搜索引擎中,解决基于自然语言查询的空间检索问题。初步构造了基于本体的空间搜索引擎的结构框架,分析了本体在空间搜索引擎中的应用范畴,并构建了相应的本体库以及解析自然语言查询的模式库,提出了自然语言式空间查询的解析方案。最后通过建立空间搜索引擎原型系统证明了该方案的可行性。

This paper proposed a solution for intelligent geographic search engine. By analyzing the disadvantages of general search engine on dealing with geographic semantic, the technology of ontology and natural language were used to solve the problem of geographic retrieval. The framework of intelligent geographic search engine was established,Ontolo- gy library and pattern library for analysing natural language were built,and geographic retrieval solution based on natural language was giverL At last,one intelligent geographic search engine prototype system was designed and implemented.
