中文摘要:
      提出引文网络入度分布模型,给出基于扩展指数函数的解析形式,并通过引文网络入度分布和概率转移速率建立一个投稿推荐算法,进行投稿推荐应用研究。应用该模型对国内9所涉农学科高校发文分布数据进行验证,解释了引文网络入度分布偏离幂律的普遍现象,为研究引文网络入度偏离幂律分布提供一定的理论基础。通过计算机模拟可以发现本文构建的推荐算法可以明显减少投稿次数,可以应用于投稿推荐。该扩展指数模型相比于幂律分布,解析式相对较复杂,但可以得到更接近实际发文的期刊分布,从实际情况来看这种改进是合理的,可为今后有效合理地利用期刊计量指标提供科学依据。
英文摘要:
      The application of contribution recommendation was studied by establishing a contribution recommendation algorithm according to the citation network in-degree distribution and probability transfer rate based on the citation network in-degree distribution model and the extended exponential function-based analytic form. The distribution of papers published by the 9 domestic agriculture universities was verified according to the citation network in-degree distribution model. The general phenomena of citation network in-degree distribution deviation power law were explained in order to provide the theoretical basis for studying the distribution of citation network in-degree distribution deviation power law. Computer simulation showed that the contribution recommendation algorithm established in this paper can effectively reduce the number of contributions and can thus be used in contribution recommendation. The analytic form of extended exponential model is more complex than that of power law distribution model, and can show the distribution of journals publishing the papers and provide the scientific basis for the rational use of .journal bibliopmetric indexes in the future.
