地理信息服务的出现为有效实现海量、多源、分布的地理信息共享和互操作提供了一种新的解决方案。随着地理信息服务技术的快速发展，如何在网络承载的海量信息环境下，自动、智能地寻找到用户需要的服务、集成不同的服务来帮助用户解决实际的地学应用问题，已经成为一个具有挑战性的问题。地理本体包含丰富的语义信息，为提高地理信息服务的自动化、智能化水平提供了强有力的手段。本研究拟对基于地理本体的地理信息服务相关理论、方法进行深入研究，主要包括：地理信息服务应用本体构建、地理信息服务语义描述模型、基于Geo-Ontology的地理信息服务搜索方法、基于Geo-Ontology的地理空间信息服务自动组合高效算法和适合地理信息服务的知识推理方法，取得基于地理本体的Web地理空间信息服务理论和技术方法上的突破，构建基于空间信息语义的地理信息服务理论和技术体系。

The appearance of Geographic Information Service provide a new solution for realizing effectively the mass, multiple source and distribution geographic information to sharing and interoperability. With the rapid development of geographic information service technology, it has been a challenging problem how to find the services which users need automatically and intelligent, and integrate different services to help users to solve the problem. Geo-Ontology comprises abundant semantic information, which offers effective means to improve the level of automation and intelligent on geographic information service. This project will research deeply the theory and methods on geographic information service based on Geo-Ontology, which includes geographic information service application ontology construction, geographic information service semantic discription model, geographic information service search and composition method based on Geo-Ontology, and knowledge reasoning method. The goal of this project are to obtain a breakthrough on geographic information service theory and method based on Geo-Ontology, and construct the system on geographic information service theory and method based on geospatial information semantic.
