Research On Multi-strategy Ontology Mapping System Based On Prediction

The purpose of the Semantic Web is a computer-understandable semanticinformation contained on the Web, along with the increasing number of ontologies inthe Semantic Web, solved a key part of the body the sharing and reuse of ontologymapping research. Commence mapping between various body substantive issues is howto solve mutual collaboration of the body, the thesis that the field of experimentalresearch.Then, existing multi-strategy ontology mapping system, the paper carried outmulti-strategy ontology mapping algorithm improvements, the angle of the algorithm tofind the mapping from the property level, instance-level results level, language level,and several different aspects to consider, fully contain semantic data in all levels of thebody, which makes the interference data exclude or weaken, so the higher the value ofsemantic information more prominent, greatly enhance precision mapping results; whilethe multi-strategy portfolio approach proposed based on trustedviewpoint of degreesprediction.Finally, based on the above research, the paper designs and implements anontology mapping subsystem. And international organizations OAEI given standarddata test set to test the final data of the system, then use the recall rate and precision rateas a measure of the standard analysis of statistical mapping results. It seems from thelast experiment, the program ensure the recall can greatly enhance the precision rate,resulting in more accurate mapping results.
