The paper analyzed the methods of extracting information from the network traffic, among which the information extraction based on the Tag marker was studied in depth. Tags, which contain specific core words, can be considered as markers of different types of information. Due to the non-standardized nature the Tag marker, a Tag often has lots of interference characters and the traditional pattern...
This paper brings forth building spatio-temporal reasoning architecture and spatio-temporal query system based on adopting geo-ontology to represent spatio-temporal information knowledge and employing SWRL rules to express spatio-temporal reasoning rules. When carrying through spatiotemporal reasoning this paper adopts Jess to be a reasoner, which is the core of the whole architecture. Before carrying...
Geo-ontology provides explicit and formalized definition of shared geographic concepts, applied to aspects such as sharing and interoperating geographic information, integrating geographic information based on semantics and geographic information service. This paper adopts geo-ontology to establish logistics domain ontology so as to store abundant semantics information and represent intricate dependent...
In future, GIS will develop in the direction of popular application. Geography information sharing has become a stringent problem needed to resolve. Because people's cognition of real geographic world is different from each other, semantic discrepancy comes into being. As a result, Realization of geography information sharing has firstly to realize GIS's semantic sharing. Geo-ontology provides generally...
