语义传感器Web中的数据管理技术研究

Research of Data Management on Semantic Sensor Web

语义传感器Web是由传感器网络技术、分布式计算技术、数据库管理技术和语义Web技术整合发展而来的。语义传感器Web能够感知、收集、整合信息,抽取新的知识并为感知器提供增强语义,因此能对环境的变化有更智能的感知,用户可以通过访问Web获取这些信息。作为计算机科学中一个新的研究领域,它有着广阔的应用前景,引起了工业界和学术界浓厚的兴趣。介绍了语义传感器Web的基本概念、特点,并着重讨论了语义传感器Web数据管理中所存在的研究问题、研究现状和研究成果。

The semantic sensor Web is an integration of sensor network techniques,distributed computation techniques, database management techniques and semantic Web techniques. They can be used for sensing, collecting, integrating in- formation, deriving additional knowledge and providing enhanced meaning for sensor observations so as to enable situa- tion awareness. Users can conveniently access this information by visiting the Web interface. The semantic sensor Web is a new research area of computer science and technology with a wide application prospects. Both academia and indus- tries are very interested in it. The concepts and characteristics of the semantic sensor Web were introduced, and the is- sues of the data management of the semantic sensor Web were discussed. The advance o~ the research on the semantic sensor Web, especially the data management, was also presented.
