With the development of mobile technology, Internet and GIS, LBS plays an important role in various applications. As the basis of LBS, the research on acquisition, processing, storage, query of mobile object trajectories has been quite mature, but the analysis and the application of movement patterns contained in mobile object trajectories is relatively lagging behind. The calculation of trajectory...
Analyzing existing location modeling, this paper addresses location issues in ubiquitous mobile computing and presents a semantic location model, which introduces query and context semantics into this user-centered model, to support context-awareness based cooperative mobile event. An event-reasoning mechanism, based on semantic matching, is established to recognize and make use of semantics. A natural...
