Topic Discovery And Evolution Analysis Of Chinese Typical Management Journal Literature

With the computer technology and network technology development, the quantity of the literature grows with index times. Literature is an important carrier to transfer information and to exchange academic ideas, which can quickly reflect social and technological dynamic, the current situation and future development trend. Therefore, it is very necessary to acquire the information of topics and topic evolution from a lot of literature.In this paper, we compare the methods of document theme analysis and decide to adopt correlated topic models (CTM) to analyze the themes of Chinese management journal from 1984 to 2009. The main analysis content includes theme composition analysis, mainstream subject analysis, journal theme strength evolution analysis, journal theme content evolution analysis, hot topic analysis and so on.(1) We use correlated topic models to analyze topic composition of Chinese management journal from 1984 to 2009 and obtain theme structure of Chinese management journal in this interim; we sort topic importance according to theme importance index defined in this paper and conclude mainstream themes.(2) We divide literature data of Chinese management journal every two years for a time segment and use correlated topic models to discovery topics in each time segment. According to theme correlation matrix, we construct the network of topic evolution. Through analyzing the topic evolution network, we can get the developing main thread of topics between different segments. According to development trend of main thread, topics can be divided into three categories, which are increasing type, decreasing type and stable type; and according to topic probability and the speed of topic growth, we analyze hot topics and cold topics.(3) In the course of topic evolution, topic area may include multiple sub-topics, which display their own evolution tendency over time. Taking the topic of enterprise management as an example in this paper, we analyze subtopic evolution and development trend of enterprise management.The result of this paper can provide help for researchers and scientific management personnel to grasp the information of topics and topic evolution in the management journal, which can avoid the repetition and waste of research work.
