| The quality of academic journals reflects the level of academic development in the country.The most widely used journal impact evaluation index is journal impact factor,but There are also some drawbacks.In recent years,many scholars have tried to find a new indicator to replace the journal impact factor,or to improve the journal impact factor,but only to evaluate the academic influence of the journal.With the development of social media and various network collaboration tools,the way to evaluate journals' influence has also changed.It is not only that journals can be evaluated according to the quality of the papers in the journals,but also through the discussion of journals in various social media.Altmetrics evaluates the impact of journals through relevant data in social media.At present,most research on Altmetrics and journal evaluation focuses on the discussion of the theoretical part,discussing whether Altmetrics can be applied to the evaluation of journal influence,or comparing the difference between Altmetrics indicators and traditional journal evaluation indicators,however,studies combining Altmetrics indicators with traditional journal evaluation indicators are not too much.By comparing the Altmetrics index with the traditional index to evaluate the results of the same journal,finding the difference and relationship between the Altmetrics index and the traditional journal evaluation index.The correlation between the two indicators is low,indicating that it is incomplete to evaluate the journal using only one method.There are also certain mutual promotion between the two evaluation methods.Higher academic influence may promote higher social influence.Similarly,higher social influence may also promote academic influence.Then,using a reasonable method to select relatively representative indicators of the two indicators,and the indicators are weighted by principal component analysis,forming a comprehensive evaluation system of journal impact evaluation. |
