| Nowadays, scientific journals published and communication already is currently the latest research and academic knowledge, it is medium platform for academic knowledge spread and popularization, and promote the scientific research, promote introduced all aspects of each field research subject, development and innovation constantly brings to the world the wave after wave surprise. In recent years, As science and technology in all areas the number of journal articles published in climbing, and published journal articles and shows the wisdom of the author, can be used as a study will not be any of the "air castles", the indispensable need to learn to absorb other people's academic achievements and references, and this reference, the reference relationship slowly absorbed and accumulated to form a network of science and technology journals cited. At present, how complex the technology from the Journal Citation Network, to understand the recent journal of science and technology and changes the hot issues, and to analyze the relationship between science and technology journals and reference to issues such as distribution, is constantly attracting people to the eye.Based on the basic method and the complex network theory as the research foundation, the Commission recorded the last 3 years (2007 to 2009) computer science field of 23 core technology journal articles data, through journal articles the reference relationship, build a complex Reference to the network of scientific journals, and the exploration and analysis of the network. The main contents and innovation of the Department include the following:First, a brief introduction to the development history of complex networks, network diagrams, complex networks in the concept and the basic concept of common, such as the average path length, degree distribution and degree of the narrative. Rules also introduced several network models, random network model, small world network model and several scale-free network model.Second, science and technology journal articles for the phenomenon of mutual reference to the establishment of a core journal reference network model and theoretical analysis is verified by simulation, the network node degree distribution model (paper citations) a power law distribution, prove that this network is a non-Scale network model. Then, that science and technology journal articles cited the effectiveness of this network model, the establishment of Science and Technology Journal Citation Network, found that the network model of accounting of the conclusions from the data with the same result, science and technology journal citation network evolution can be clear by the Model description.Third, the section created for the journal citation data, using statistical nature of the social network of 23 journals cited relationship between the changes in distribution, while application of complex network theory of the reference relationship between science and technology journals behavioral characteristics, and quantitative Description of the journals cited each other on the topology of the network-related characteristics were analyzed and summarized, and were derived from whole to part, and in-depth analysis of the importance of a journal and also selected a few hot spots to observe the distribution and change keywords . |
