Abstract：［Purpose/significance］ Based on the interconnection of vocabularies,this paper constructs vocabularies network,divides the relationship among vocabularies into reuse,metadata and mapping,excavates the characteristic distribution of vocabularies under each relationship network,and then analyzes the hidden relationship under the explicit correlation of vocabularies,and provides reference for the related research of vocabularies construction according to the research results［Method/process］ This paper selects the vocabularies registered in the LOV platform as the research object,uses the social network analysis method to analyze the statistical and structural characteristics of the vocabularies network formed based on seven different link predicates,and makes an indepth analysis of the core vocabularies,network structure and the interconnection of vocabularies in each vocabularies network［Result/conclusion］ The research summarizes the structural characteristics of different vocabularies networks,which is helpful to understand the types and current situation of vocabularies interconnection,and provides some feasible suggestions for vocabularies construction
