Difference of Influencing Factors of Citation in Scientific Papers from the Perspective of Subject Theme:An Empirical Study of Library and Information Science
Examining the factors influencing citation frequency from the perspective of subject themes can provide targeted guidance for researchers in writing and optimizing their papers,and also provide a new perspective and idea for scientific research evaluation.This study uses 43 228 valid papers published in 18 CSSCI-indexed journals in library and information science from 2011 to 2020.By applying the LDA topic model to extract and identify themes from paper abstracts,and using a negative binomial regression model,we empirically investigate the factors influencing annual citation frequency from overall,thematic,and thematic classification perspectives.The findings reveal both commonalities and differences in the factors influencing annual citation frequency across subject themes.Consistent factors include funding support,paper length,paper age,and download frequency.In contrast,factors such as title length,number of keywords,and number of authors show varying impacts on annual citation frequency.
