Abstract

Abstract: Start with current research of Scientific Collaboration Network（SCN） and BA network model，a new mathematic model of SCN is proposed based on research interest of scientists，then the network evolution model of SCN which is tallied with its real characteristics has been built up based on interest similarity.The result of simulation experiment shows that the degree distribution of the network built up by the new math model is a power-law distribution with an exponent-3.

Key words: scientific collaboration network, network evolution model, interest similarity, scale-free network

摘要： 从科研合作网络的研究现状入手在BA网络模型的基础上，基于科研工作者研究兴趣，给出了一个新的科研合作网络的数学模型，并建立了一个基于兴趣相似度的符合科研合作网络真实特性的网络演化模型。初步的仿真实验结果表明，按照该模型构造出来的网络度分布服从幂指数为-3的幂律分布。
