[Purpose/Significance] Scholar profiles are widely applied in various precision services within the academic field, such as paper review, project evaluation, targeted recommendations, and talent recruitment. Topic tags play a critical role in identifying scholars in the same specialized subfield. This paper optimizes the method for calculating scholar topic tags to more accurately identify scholars within specific subdisciplines. [Method/Process] This paper proposed a theoretical framework: scholar profiles should comprehensively incorporate evaluation information such as scholars' research interests and academic capabilities, while also reflecting their research fields and academic standing within those fields. This paper integrated topic tags with evaluation data, using the latter as a factor for weighting topic tags. An algorithm was proposed for calculating high-scoring topic tags for scholars, incorporating three dimensions: the quantity of published papers, the author's position in the author list, and the citations of the papers. [Result/Conclusion] From the perspective of individual scholar profiling, high-score topic tags can delineate the main specialized research areas of a scholar. For the need to identify experts within a discipline, high-score topic tags can help pinpoint the most outstanding and core scholars in that field.
