摘　　要：有效地挖掘学术大数据,分析论文的学术影响力,有助于科研工作者获取重要的信息。文本内容与学术网络结构的动态变化,会对论文的学术影响力排名结果产生重要的影响。但现有的论文学术影响力排序算法或是缺乏对文本内容的考虑,或是缺乏对学术网络结构的动态变化的考虑。针对该问题,提出了一种学术影响力排序算法,称之为基于主题声望和动态异构网络的学术影响力排名(TND-Rank)。TND-Rank衡量了论文主题在某一时间对论文的影响,并将其嵌入考虑时间因素的论文影响力排序算法中。TND-Rank通过考虑影响主题声望水平、期刊、作者、时间等多种因素的综合影响来计算论文的动态学术影响力相关排名。在实验中,对AMiner数据集1936-2014年间发表且信息保存完整的文章进行了分析,将所提算法与近年来的4种相关算法进行了比较,采用Spearman相关系数、归一化折损累积增益(NDCG)和分级平均精度(GAP)对算法性能进行了评估。实验结果验证了TND-Rank算法的可行性和有效性,其可以有效地综合各种信息对论文的学术影响力进行排序。Effectively mining academic big data and analyzing academic influence of papers are benefical for researchers to obtain important information.The dynamic changes of text content and academic network structure have an important impact on the ranking results of academic impact.However,the existing ranking algorithms of academic influence of papers either lack consideration of text contents or the dynamic changes of academic network structure.To solve this problem,this paper proposes an algorithm for ranking academic influence,which is called TND-Rank,based on topic reputation and dynamic heterogeneous network.In TND-Rank,the impact of the topic on the paper at a certain time is measured and embedded to the paper influence ranking algorithm that takes into account the time factor.The dynamic ranking related to the academic impact of a paper is calculated by comprehensively considering the influence of various factors,i.e,the level of topic prestige,journal,author,and time etc.In the experiments,the AMiner data set published between 1936 and 2014 with complete information are analyzed,and compared with four related algorithms in recent years.Spearman correlation coefficient,normalized discounted cumulative gain(NDCG)and graded average precision(GAP)are adopted to evaluate performance of the algorithm.Experimental results verify the feasibility and effectiveness of the proposed algorithm TND-Rank,which can effectively synthesize various information to rank the academic influence of papers.
