摘要

地理空间数据可用性的增加为知识创造和传播提供了难得的机会。为了发现合适的数据源，基于关键字的目录搜索变得不准确。这背后的主要原因是数据库模式中现有的语义异构性，由不同的服务提供者部署。这就要求对空间目录进行语义管理。本文提出了一种基于本体的目录语义创建和管理方法，解决了地理空间存储库之间的语义异构和空间查询的不兼容问题。此外，目前还没有空间目录语义搜索的标准。它将通过为空间目录提供语义意义来增强数据提取过程。

Ontology based framework for semantic resolution of geospatial query

Increasing availability of geospatial data provides exceptional opportunities in knowledge creation and distribution. For the discovery of suitable data sources, keyword based search in the catalogue becomes inaccurate. The main reason behind this is the existing semantic heterogeneity in the database schema, deployed by different service providers. It necessitates the semantic management of the spatial catalogues. This paper presents an ontology based approach which is useful to create and manage catalogues semantically, hence resolving the semantic heterogeneity between geospatial repositories and incompatibility with spatial queries. Further, there is no standard available for semantic searching of the spatial catalogue till date. It will enhance the data extraction process by providing semantic meaning to the spatial catalogue.
