Systematic Error Research of Entropy Weight Method in Academic Journal Evaluation
[Purpose/significance]The entropy weight method is an important evaluation method for academic journals,and its system-atic error is worthy of attention.[Method/process]This paper introduces the error theory into the multi-attribute evaluation of aca-demic journals,analyzes the generation mechanism of the system error of the entropy weight method,and puts forward a solution.[Re-sult/conclusion]The research shows that the error problem of the entropy weight evaluation system of academic journals must be paid enough attention to,which widely exists in many links such as evaluation index selection,weight empowerment,data standardization,and result publication.To reduce the system error of the entropy weight method,we must intervene in all aspects.In addition to choos-ing the evaluation index reasonably and analyzing the rationality of the weight,we should pay attention to the standardization method.Using the sigmoid function to standardize is an effective means.As a part of the evaluation method,the entropy weight method will have an impact on the systematic errors of other evaluation methods.The overall impact is relatively small,but it should still be taken seriously.[Innovation/limitation]The analytical paradigm of the systematic error of the entropy weight method can be widely used in other academic evaluation methods.
