An improved method based on semantic features analysis of tag systems is proposed to solve the problem that existing tag systems are coarse-grained and their hierarchical structures are unapparent. The method analyses similarity among multiple tag systems on different websites
learns the relationships of synonym mappings and hypernym-hyponym mappings among these systems
and further obtains a fine-grained and hierarchical tag system. In order to evaluate the performance of the algorithm
two test metrics
the tag coincidence degree and the hypernym-hyponym coincidence degree
are proposed to assess the accuracy of merging and constructing tag systems. Experimental results show that the method improves the tag coincidence degree and the hypernym-hyponym coincidence degree by more than 5%
and it efficiently builds a tag system with higher precision and applicability
