Research on Information Science Knowledge Network and Its Evolution Trend Based on Big Data

In the development of network technology, with big data technology as the core information science presents the development trend of the interdisciplinary and multidimensional, practical work are also put forward more research topic, actively looking for information science disciplines of potential partners, clear the subject structure and evolution trend of the theme of the help scholars more quickly master the development of the discipline of frontier and hot, It provides effective basis for decision-makers and managers of scientific research. Therefore, on the basis of understanding the structure and development trend of information science discipline, this paper takes knowledge network as the core, deeply discusses the corresponding structure and evolution trend, and divides information science discipline into eight categories for empirical analysis. The final results show that this research can grasp the research trend of subject topic in a certain sense, and has a positive influence on improving the research method of subject knowledge network.
