| With the development of science and technology,knowledge communication between disciplines have become more frequent,and interdisciplinary research has become an important development trend in scientific research.The interdisciplinary researches mostly start from the perspective of citations and and the core link is to classify papers into the discipline of their journal.However,this classification is not accurate,and the error is greater for comprehensive journals.The Chinese academic databases are mainly based on the Chinese Library Classification Scheme(CLC)to classify journals and individual papers at the same time,which effectively reduces the error of paper classification through the journal classification system.This study conducts interdisciplinary research at paper-level classifications of science,and uses the academic papers of the 568 source journals of CSSCI from 2008 to 2018 as the research data.Based on the attribution relationship between the paper and the CSSCI disciplines,the relation between the paper's multiple classification codes,the relation between the paper classification codes and the journal classification codes,the relation between the paper classification codes and the reference classification codes,this sduty uses statistical analysis and social network analysis methods to explore the interdisciplinary situation in the field of Arts,Humanities and Social Sciences in China under different discipline granularity.Then we compare the interdisciplinary research results of the paper-level classification of science and the citation perspective.Firstly,among the 25 disciplines classified by CSSCI,under different discipline granularity,the three disciplines of University Journal,Comprehensive Social Science,Ethnology and Cultural have the highest discipline diversity.They contain rich disciplines,and the proportion of disciplines is relatively balanced.Secondly,in the knowledge communication network where co-occurrence of paper classification codes,the interdisciplinary knowledge communication of Economics is relatively active,but a large amount of knowledge communication occurs between related economics categories.In the research based on the interdisciplinary knowledge exchange community and the core nodes of the network,it is found that Literature and Science and Education and Sports is the more important category in the Humanities and Social Sciences,especially Information and Knowledge Dissemination,Education,which have an obvious intermediary effect and have a great influence on the knowledge communication of Humanities and Social Sciences.Thirdly,in the knowledge communication network of tier-1 categories associated with papers and journals,Social Sciences has absorbed a large amount of knowledge from other categories.Among them,Economics,Politics and Law have contributed the most knowledge;Economics is more inclined to transfer knowledge to other categories.In the knowledge communication network of tier-2 categories,Science and Science Studies have absorbed more knowledge in Economic Management,Information and Knowledge Dissemination;Automation and Computer Technology is more inclined to transfer knowledge to other categories.Fourthly,in the citation network of library,information and philology,Literature and Science and Education and Sports mainly absorb knowledge from other disciplines and have a high degree of disciplinary diversity.Among them,Computer Technology and Economics have contributed more knowledge to them.Finally,through the comparative analysis of the interdisciplinary research results of the paper-level classifications of science and the citation perspective,it is found that the interdisciplinary situation revealed by the two perspectives has both similarities and differences.In addition,from the perspective of the paper-level classifications of science,the interdisciplinary situation of different levels can be studied by dividing the granularity of categories,and the research perspective is more detailed. |
