New Tree Segmentation-based Ontology Mapping Algorithm
Jianer Chen · Journal of Chinese Computer Systems · 2009
The efficiency of ontology mapping is still low due to the deficiency of the existed mapping algorithm and the inherent complexity of the ontology.This paper proposes an ontology mapping algorithm based on tree segmentation.It first divides the ontology into a set of sub-trees with different granularities according to the structure of the ontology,then uses sub-tree mapping algorithm to map them.Theoretical analysis and experimental results show that the algorithm has made great improvement on the mapping efficiency compared with the current mapping algorithms while preserving the mapping precision and recall.
