Method and key techniques of transportation data standards conformance inspection

For the lacking of inspection method, the transportation data standards are compiled weakly in the process of transportation information system developing, which increases the difficulty of data sharing and exchange. In order to improve the conformance of data with the standards of transportation information systems, a method named “data standard conformance inspection” is proposed in this paper. Firstly, for inspection convenience, data is classified into individual data, data item and data collection according to its granularity, the standardization requirements of data item and data collection are discussed separately, and also the transportation data standards are reclassified in data granularity. Secondly, the concept, objects and contents of data standard conformance inspection for transportation are put forward and studied. The solutions of key inspection techniques are also introduced, including “semantic similarity based on weighting edit distance” and “phase matching based on hierarchical structure of data element”, which are two mutually complementary methods of Chinese phase matching to data element name, data item properties inspection methods applying to main database management systems. The system based on the method in the paper has been applied overall the country.
