Expanding scholar labels with research similarity and co-authorship network

[Objective] This paper tries to add more academic labels for researchers from scholarly abstracts, aiming to predict their future research interests. [Methods] First, we extracted the basic labels from abstracts with the TF-IDF method. Then, we identified researchers sharing similar academic interests and co-authoriship. Finally, we expanded the basic labels with those from similar scholars and team members. [Results] Compared with existing methods, the proposed one increased recall rate of predicting by 8.33% on average. [Limitations] Our sample size was small, and we only examined scholarly articles in one language. [Conclusions] The proposed method could predict scholars’future research interests.
