  1. Research on Interoperability of Metadata in Classification Schemes——Construction of automatic mapping system between CLC and DDC Jianbo DaiHanqing Hou Ling Cao Mail: hqhou@njau.edu.cn

  2. Introduction Metadata interoperability between different classifications • Necessity • Importance • State-of-art Renardus ,HILT,and other Subject information gateway ect.

  3. Module of Mapping System • Data processing module • Automatic mapping module • Batch processing module • The module of geography subdivision processing • System maintenance module

  4. The Principle of Automatic Mapping System (1)-theory basis • The consistence of structure of class schemes • the similarity of concept expression of classes between CLC and DDC

  5. The Principle of Automatic Mapping System (2)- Feasibility • Class concept can be expressed by several words usually;calculate the semantic similarity between the concept elements • get the whole similarity through the calculation of similarity of concept elements

  6. The Principle of Automatic Mapping System (3)- Max Similarity Value • only the comparison between the parts, which play the same role, is available • calculate the overlap degree of the concept of class, namely semantic similarity, then decide the mapping relationship of class.

  7. Construction of Automatic Mapping System • Regulation of Automatic Mapping • The Choice of Mapping Methods

  8. Application of Automatic Mapping System • Mapping between two classes • Construction of concordance • Cataloging of MARC • Class number conversion in subject information gateway • Information retrieval in internet

  9. THE END Thanks for All
