基于主题覆盖度的科研项目评审专家组推荐方法研究

[Objective] Aimed at the peer review process of scientific research projects, this paper measures the coverage of reviewers'knowledge on research project topics and constructs expert groups of maximum topic coverage. [Methods] We proposed three principles for recommending reviewer groups for research projects: the maximum topic coverage principle, the maximum knowledge matching principle, and the appropriate workload principle. Then, we developed a method for identifying the research topics of reviewers and projects using the Overlapping K-means. To achieve maximum topic coverage, we constructed a reviewer group recommendation model based on topic coverage, transforming the recommendation problem into an optimization problem. [Results] In two controlled experiments, the reviewer groups constructed by the proposed method increased the topic coverage by 32.38% and 29.01%, respectively. [Limitations] We need to quantitatively explore how to achieve multi-objective optimization for recommending reviewers for research projects according to the three principles. [Conclusions] This research took the reviewer group recommendation for the National Natural Science Foundation of China project application as a case study. It verified the feasibility and effectiveness of the proposed method through qualitative and quantitative analysis.
