| Abstract: | This paper constructs normalized keyword intersection of two disciplines from core periodicals and then obtains high-frequency intersecting keywords and their co-word matrix. Based on that, the paper uses keywords analysis and social network analysis to discuss the overall characteristics, subject construction, internal relations and evolution of crossing research hotspots of two disciplines. Taking the two disciplines of Library and Information Science and Journalism and Communication Studies as examples, the paper verifies the feasibility of the idea and gets some useful conclusions. |
