Abstract: 【Purpose/significance】The identification of academic value of papers is an important part of the evaluation of scientific and
technological achievements. Using the contribution degree of papers and the weighted average citation index can realize the early iden? tification of academic value of papers and promote the early occurrence and realization of the value of scientific and technological achievements【. Method/process】Firstly,based on pattern matching and co-occurrence analysis,this paper extracts the problem knowl? edge element relationship and method knowledge element relationship; Secondly,it retrievals according to the knowledge element rela? tionship between problems and methods,and constructs the literature collection related to problems and methods; Then,based on the relevant literature collection,the calculation method of academic value index of papers is proposed,and the early identification of aca? demic value of papers is realized through the normalized contribution-weighted average citation matrix; Finally,the experimental re? search is carried out with the data of journal papers in the field of Library and Information.【Result/conclusion】The experimental re? sults show that the method proposed in this paper can realize the early identification of academic value of papers,and is conducive to promoting the popularization and application of high-quality and high-level scientific and technological achievements.【Innovation/limitation】In the follow-up research,more paper knowledge elements will be included in the calculation to further improve the early recognition effect of academic value of papers.
