The establishment and application of traffic domain ontology based on data element

Since the research of transportation ontology and the establishment of traffic data element has been separated from each other, which has caused large workload on ontology establishment and inadequate continuity of the application of standers. To solve these problems, we put forward a method to establish the ontology about traffic information. In this paper, we analyzed the similarity of logical structure relationships between ontology and traffic information data element, the corresponding relationships of constituent elements and the similarity of these relationships firstly, demonstrated the feasibility of interconversion between data element and ontology. Secondly, we reconstruct the data element standard based on object-oriented methods, on this basis, we elaborate how to build a transportation ontology.
