Journal influence evaluation model based on citation analysis and altmetrics

To optimize the evaluation method of journals and establish the evaluation system of academic journals, this paper combines the citation indicators and Altmetrics indicators to build a journal impact evaluation model.Firstly, we collected 7 citation indicators and 17 Altmetrics indicators as the initial indicator of journal evaluation.Then we used correlation analysis, reliability and validity analysis, principal component analysis to determine the core evaluation indicators and used the weighted grey correlation method to calculate academic impact (F1) and social impact (F2).On this basis, build a journal evaluation model, the Traditional and Altmetrics model.Finally, we conducted an empirical study using 74 SSCI geography journals.The study results show that F1 and F2 have differences in the evaluation of journal influence.The TA model has good stability in journal evaluation, and the journal partition effect of the model is similar to JCR.The TA model integrates F1 and F2 dimensions to evaluate journal influence, which provides a new idea for evaluating academic journal influence.
