摘      要：Purpose:Research dynamics have long been a research *** is a macro perspective tool for discovering temporal research trends of a certain discipline or subject.A micro perspective of research dynamics,however,concerning a single researcher or a highly cited paper in terms of their citations and“citations of citations(forward chaining)remains ***/methodology/approach:In this paper,we use a cross-collection topic model to reveal the research dynamics of topic disappearance topic inheritance,and topic innovation in each generation of forward ***:For highly cited work,scientific influence exists in indirect *** modeling can reveal how long this influence exists in forward chaining,as well as its *** limitations:This paper measures scientific influence and indirect scientific influence only if the relevant words or phrases are borrowed or used in direct or indirect *** or semantically similar concept may be neglected in this *** implications:This paper demonstrates that a scientific influence exists in indirect citations through its analysis of forward *** can serve as an inspiration on how to adequately evaluate research ***:The main contributions of this paper are the following three ***,besides research dynamics of topic inheritance and topic innovation,we model topic disappearance by using a cross-collection topic ***,we explore the length and character of the research impact through“citations of citationscontent ***,we analyze the research dynamics of artificial intelligence researcher Geoffrey Hinton’s publications and the topic dynamics of forward chaining.
