Research On Multidimensional Evaluation Of Journal Influence Based On Altmetrics

Technological innovation is the first driving force leading the country's economic development,and it is also a key factor for enterprises to succeed in market competition.Under the background of economic globalization,fluctuations in domestic and foreign economic policies will change the mar The evaluation of academic journals is an important topic in academic communication and scientific development.It is of great significance to do a good job in the evaluation of academic journals to help standardize the authority of journals,improve the quality and facilitate scholars to obtain results.With the rapid development of academic networking in Web2.0 environment,the generation and dissemination of academic journals have changed.The way of academic communication is not limited to traditional literature transmission,but scholars begin to conduct academic communication on Twitter,Facebook,weibo and other social media.In recent years,more and more questions have been raised about the impact factors,citation frequency and other evaluation indexes that have been used to evaluate academic achievements.In this context,the proposal of Altmetrics has aroused extensive research in the academic community.Many scholars found that Altmetrics were not universally applicable in the study of the characteristics of Altmetrics,and there were some differences in the indicators of different academic journals.In addition,current research on the impact evaluation of Altmetrics in journals mainly discusses the evaluation perspective and applicability of the new Altmetrics model by constructing an indicator model based on Altmetrics and comparing it with the traditional indicator model.The author attempts to build a comprehensive model of journal influence by combining the indicators of "attention","social influence" and "academic influence" on the basis of previous studies.And on the basis of Wo S subject classification selected JCR impact factor of the top 10 of 13 subject in all kinds of journals as evaluation object,and through the indicators cover for "interest","social influence" indexes,to reserve all indicators,the reliability and validity analysis,correlation analysis,screening of all kinds of academic journals of the underlying index.Then adopt the method of index fusion will measure indexes,the combination of three different influence factor analysis by SPSS configuration index weight,periodical influence evaluation index model was constructed to determine the comprehensive influence of interdisciplinary journal score,and consistency check with AAS and SJR value,explore the applicability of the comprehensive influence index model in different fields.It is found that the academic influence measured by the previous periodical evaluation indexes is not the same,and the evaluation results may not be synchronized.The effective combination of the three indexes to measure different influences can build a multi-angle and comprehensive index system to evaluate the comprehensive influence of periodicals in a more objective way.Moreover,there are differences in retained indexes and index weights among different fields.By reflecting the disciplinary characteristics of these indexes,it can provide reference for the rational utilization of indexes in the evaluation of journals with disciplinary characteristics.
