Abstract
Evolution and development of knowledge is an important issue of Library and Information academia. In this study, from the perspective of time series, keywords of literature are extracted in particular domain, and domain knowledge networks are constructed based on keyword co-occurrence relationship. Using a variety of analytical methods network density, clustering coefficient, characteristic path length, degree centralization, betweenness centralization, etc., the development of situation in domain knowledge networks is tracked and analyzed. The results show that the overal trend of domain knowledge development is moving to the status of smal world, and centrality of domain knowledge wil appear gradual y with the development of knowledge. A helpful at empt is made for analyzing and judgment on development tendency of domain knowledge based on complex network theory and methods.关键词
