Abstract
The current method used to perform the book quality online evaluation for large library is difficult to acquire the important coefficients of the subjective and objective weights of the book quality evaluation indexes,and has the problems of complex actual operation and big book quality evaluation error. Therefore,an optimal combination weights based design method of the book quality online evaluation system for large library is proposed. With the method,the book quality evaluation index set of the library is acquired,and the entropy method is used to calculate the information entropy of the book quality evaluation in-dex. On this basis,the subjective and objective weighting methods are combined to empower the evaluation index of the book quality,and obtain the subjective and objective weight sets of the book quality evaluation for large library. The moment estima-tion theory is adopted to calculate the expected value of the subjective and objective weights of the book quality evaluation index to get the important coefficients of the subjective and objective weights of each book quality evaluation index for large library,so as to establish the book quality online evaluation system for large library. The experimental results show that the proposed method can reduce the random error and system error in book quality evaluation process,improve the credibility of the book quality evaluation results,and has strong applicability.关键词
