摘要:

衡量一篇研究论文影响力的标准是它被引用的次数。然而,论文被引用的原因可能有很多,引用计数提供的有关论文对后续出版物内容影响程度的信息有限。因此,我们提出了一种新的方法来量化语言的影响,在时间戳的文档集合。有两个主要步骤:首先,使用上下文嵌入和词频识别词汇和语义变化;其次,通过估计具有低秩参数矩阵的高维Hawkes过程,将关于这些变化的信息聚合成每个文档的影响分数。我们发现,这种语言影响力的措施是预测的$\textit{future}$引用:语言影响力的估计,从两年后的论文的出版是相关的,并预测其引用计数在接下来的三年。这是证明使用增量时间训练/测试分裂的在线评估,与一个强大的基线,包括初始引用计数,主题和词汇功能的预测。

英文摘要:

A standard measure of the influence of a research paper is the number of times it is cited. However, papers may be cited for many reasons, and citation count offers limited information about the extent to which a paper affected the content of subsequent publications. We therefore propose a novel method to quantify linguistic influence in timestamped document collections. There are two main steps: first, identify lexical and semantic changes using contextual embeddings and word frequencies; second, aggregate information about these changes into per-document influence scores by estimating a high-dimensional Hawkes process with a low-rank parameter matrix. We show that this measure of linguistic influence is predictive of $\textit{future}$ citations: the estimate of linguistic influence from the two years after a paper's publication is correlated with and predictive of its citation count in the following three years. This is demonstrated using an online evaluation with incremental temporal training/test splits, in comparison with a strong baseline that includes predictors for initial citation counts, topics, and lexical features.
