Abstract
The goal of this paper is to conduct a first comparative analysis on citation intents across multiple scientific disciplines. To this end, we conducted a data-driven investigation into the characteristics of citation intents utilizing a large-scale dataset of 17,717 academic papers and 2,345,674 citation contexts from 21 Web of Science subject categories. We analyzed five key characteristics:
i
) inter-category distribution of citation intents,
ii
) average number of citation intents per article,
iii
) age distribution of citation intents,
iv
) similarity of the age distributions of citation intent, and
v
) predictability of the number of citation intents. We found out that there are significant differences in all five characteristics across different research disciplines. Specifically, Philosophy, Sociology, Area, and History prioritize
Background
and
Motivation
intents while exhibiting minimal engagement with
Uses
and
Extends
. Conversely, Computer Science AI represents a unique case, characterized by a dominant prevalence of
Uses
and
Extends
intents alongside the least frequent use of background-oriented citations. Furthermore, the age distributions of citation intents exhibit the lowest similarity in Area, and History. In terms of predictability, Biotechnology and Plant Science exhibit the highest correlation levels in citation intent counts, whereas Sociology, Philosophy, and History yield the lowest correlation coefficients. Our comparative analysis not only uncovers cross-disciplinary variations and establishes a standardized framework for the comparative analysis of citation intents, but also has applications in advancing the normalization of scholarly indicators, facilitating trend detection, and supporting curriculum design for specific scientific disciplines.
