中文摘要: 本体技术的发展为解决地理科学中普遍存在的语义异构问题和地理科学系统智能化设计提供了新的研究思路。 然而本体技术在当前地学应用中普遍存在着语义部件与应用部件耦合度高,语义部件可重用差,以及语义部件支持的应用形式比较单一,应用范围则比较窄的状况。这使得系统对需求变化的应变能力很差并难以维护;系统中语义部件的推理能力无法得到充分发挥;新的本体应用形式也很难迅速整合到现有的系统中。本研究将语义系统从地理科学系统的智能化设计中独立出来,提出WGOS层次化语义系统模型的概念及解决方案,在架构层面上直接提供对语义系统应用层服务的快速开发与部署的支持,从而解决本体技术在当前地学智能化系统应用中存在的各种问题。本项目的研究成果将为空间数据服务的智能化提供核心推理基础设施,对于克服当前OWS框架下空间数据服务应用中普遍存在的语义异构问题、提高空间数据服务的智能化程度具有重要的理论及应用意义。

英文摘要: Ontology technology for intelligent design to solve common semantic heterogeneity in geographical system provides a new research method. However, ontology technology in geo-science applications usually face the problems of high coupling degree between semantic and application components, low reusability of semantic components, and simple form of semantic application. These problems limit the flexibilty of semantic sysem and make it difficult to maintain. Moreover, the reasoning ability of the semantic components in the system can not be given full play, and new ontology application is difficult to be quickly integrated into existing systems. In this study, the semantic components will be separated from the geographical system. We propose a WGOS (Web Geo-Ontology Service) hierarchical semantic model, which can support the rapid development and deployment of application layer services in semantic systems at the architecture level. So as to solve the various problems above. The research results of this project will provide the core reasoning infrastructure for spatial data service applications to overcome the semantic heterogeneity problems in current OWS frameworks, and improve the intelligent degree of spatial data services.
