Data Intergration Of Power Information System Based On Ontology

摘要

Power system data distributed in different locations of heterogeneous information systems on the multiple network . These systems are different in the architecture and also in different areas of expertise. In view of the above questions thispaper has proposed a power system integrated research plan baseed on ontology, mainly discussed on local ontology mapping between the data source. Focus on how to convert from the database relational model to OWL ontology and gives the ER model to OWL ontology from the conversion algorithm. Compared with the similar method, this method is automated build ontology, and overcomed the manually created ontology can bring a lot of tedious work.
