Supporting Environmental Information Systems and Services Realization with the Geo-Spatial and Streaming Dimensions of the Semantic Web

[摘要] Environmental Information Systems and Services require ex-ible discovery and chaining of distributed environmental services to sup- port a large number of concurrent decision processes. The ability to cope with geo-spatial features of the environment and to process in real time huge and possibly noisy data streams are two critical factors in supporting such decision processes. Solution to separately cope with the two aspects are available. The geo-spatial aspect has been studied for decades in the Geographic Information System (GIS) community. Data Stream Management Systems (DSMS) are the result of a decade of investigation on data stream processing by the database community. However, seamless integrated usage of GIS and DSMS is still a di- cult task. Recent developments of the Semantic Web community have been trying to overcome the barriers between these two technologies by proposing to extend the Semantic Web with both a Geo-Spatial and a Streaming dimension. In this paper, these two dimensions of Semantic Web are show-cased for environmental monitoring and management in
