融合学科关联度的期刊跨学科评价指标研究OA

[Purpose/Significance]To address the limitation of interdisciplinary journal evaluations that overlook disci-plinary bias in citations,the study constructs a new metric that reflects disciplinary association while accounting for stan-dardized impact.[Methods/Process]The paper proposed the Discipline Association Index(DAI),a composite measure integrating interdisciplinary relative citation volume,citation timeliness,and citation balance.By combining DAI with the Mean Normalized Citation Score(MNCS),the study constructed the Interdisciplinary Score(I Score).Empirical validation was conducted on 342 journals across Materials Science-Multidisciplinary,Computer Science-Artificial Intelligence,and Information Science&Library Science from 2000 to 2020.[Result/Conclusion]The I Score provides a fine-grained inter-disciplinary relative influence matrix of journals.Meanwhile,I Score p based on the PageRank algorithm can identify jour-nals that serve as bridges in cross-disciplinary citations and those exhibiting"high citation counts but low interdisciplinary influence",thereby mitigating disciplinary bias in citations to some extent.
