Yang Hong-yan · Journal of Anshan Normal University · 2006
At present,unifying heterogeneous information has been the puzzle of processing heterogeneous information under WEB frame.The foundation on which this paper is built is the theory of domain ontology.By dint of the description method of objected information object,objected description of heterogeneous information as expressing form of information concept model,and the semantic relation of concept model is as internal contact of heterogeneous information extracting rule.An expression method based on RDF(Resource Describe Frame) is built on WEB.By means of Ontology semantic logic relation,an extracting rule of heterogeneous information is proposed in heterogeneous information integration.Thus heterogeneous information can be processed automatically.The method used in extracting heterogeneous information of fire-fighting archive on WEB,and received a better experiment effect.
