AI总结:

本研究构建了融合语义与引用影响力网络的2100万篇论文级演化知识图谱,用机器学习预测未发表研究思路的影响力,多数实验AUC超0.9,可为未来启发科学创新的人工缪斯提供支撑。

摘要:

科学出版物的指数级增长给人类研究者带来了严峻挑战。这迫使人们将注意力集中在更狭窄的子领域,使得在自身领域之外发现有影响力的新研究思路与合作机会变得十分困难。尽管目前已有多种预测科学论文未来引用量的方法,但这些方法都要求研究已完成且论文已撰写完毕,通常是在研究思路提出很久之后才评估其影响力。我们在本研究中展示了如何预测研究者尚未发表的全新思路的初始影响力。为此,我们构建了一个基于2100多万篇科学论文的大型演化知识图谱,该图谱融合了从论文内容生成的语义网络,以及由论文历史引用关系构建的影响力网络。借助机器学习方法,我们能够高精度地预测该演化网络未来的动态变化(大多数实验的AUC值超过0.9),进而预测新研究方向的影响力。我们设想,这种预测新思路影响力的能力将成为未来人工缪斯系统的关键组成部分,这类系统能够启发具有影响力且有趣的全新科学思路。

英文摘要:

The exponential growth in scientific publications poses a severe challenge for human researchers. It forces attention to more narrow sub-fields, which makes it challenging to discover new impactful research ideas and collaborations outside one's own field. While there are ways to predict a scientific paper's future citation counts, they need the research to be finished and the paper written, usually assessing impact long after the idea was conceived. Here we show how to predict the impact of onsets of ideas that have never been published by researchers. For that, we developed a large evolving knowledge graph built from more than 21 million scientific papers. It combines a semantic network created from the content of the papers and an impact network created from the historic citations of papers. Using machine learning, we can predict the dynamic of the evolving network into the future with high accuracy (AUC values beyond 0.9 for most experiments), and thereby the impact of new research directions. We envision that the ability to predict the impact of new ideas will be a crucial component of future artificial muses that can inspire new impactful and interesting scientific ideas.
