Research on Novelty Measurement Indicator of Academic Papers Based on the Atypical Recombination of Knowledge

2025-12-21

AI Summary

To address the temporal lag between publication and novelty assessment in academic papers, this paper proposes the “knowledge eccentricity” metric—a quantitative measure of a paper’s semantic deviation from established domain knowledge structures, derived from a constructed domain-specific knowledge graph. Methodologically, it introduces the first computable formalization of “atypical knowledge recombination” as eccentricity, integrating cross-cohort bibliometric modeling and regression analysis to validate underlying mechanisms. Empirical results reveal a significant negative correlation between team size and novelty, while reference count exhibits a positive effect. The metric enables immediate post-publication evaluation, overcoming the inherent time lag of citation-based metrics. It offers theoretical novelty through its semantic-graph-based foundation and practical feasibility via scalable computation, establishing a real-time, objective, and interpretable paradigm for scholarly evaluation.

Abstract

The advancement of science is inherently dependent on the recombination of existing knowledge, and innovative research typically relies on the atypical recombination of established knoweldge bases. This study introduces a Knowledge Eccentricity to enable timely assessment of the novelty of research outputs by quantifying their degree of deviation from the existing knowledge system. For empirical analysis, we selected sample data including research articles published in Science and Nature, top 1% highly cited papers, and zero-cited papers for the year 2005, 2010, 2015, 2020, and 2025. We calculated the knowledge eccentricity scores for these papers and examined their potential influencing factors. The results indicate that team size exerts a significant negative effect on paper novelty, meaning larger team size is less conductive to enhancing the novelty of research outputs. Conversely, the number of references shows a signifcant positive correlation with paper novelty, which means that a greater number of references is associated with a moderate imporovement in a paper's novelty. The proposed indicator offers strong timeliness and operability, allowing for the evaluation of a paper's novelty immediately upon its publication.
