Application of the semantic annotation technology based on ontology

Abstract

To resolve the semantic conflicts in the process of data exchange, the ontology is made full use to describe the characteristics of the relation between concept, adding semantics to XML Schema. In this paper, the semantic conflict resolution model is introduced, the indirect method is applied and the ER model is applied to realize the semantic mapping from relational schema to XML Schema, this is the so-called semantic annotation technology. In the field of railway, there exist some semantic conflict in the data exchange, by the Ontology OWL fragment extracted from the experiment, semantic conflict will be reduced and even eliminated.
