The evaluation reform of university faculty is an important component of educational evaluation reform and a crucial guarantee for stimulating the intrinsic motivation of university faculty. Self-evaluation by faculty is a key aspect of the comprehensive evaluation system for university faculty. Currently, self-evaluation largely relies on manual statistics and analysis, which presents issues such as strong subjectivity in the evaluation process, low work efficiency, and poor accuracy. Therefore, this paper proposes a method for extracting keywords from university faculty self-evaluation based on an improved PositionRank algorithm. First, faculty self-evaluation data is collected and cleaned to remove redundant and anomalous data, improving data quality. Second, a graph-based keyword extraction algorithm is used to generate high-quality label data. Finally, the improved PositionRank algorithm is employed to adaptively learn the attention weights between phrases, achieving accurate keyword extraction. Experimental results show that this method efficiently identifies key content in faculty evaluations, significantly improving the accuracy of keyword extraction while demonstrating strong evaluation consistency. It helps reveal the core strengths and areas for improvement of faculty and provides strong technical support for improving the university faculty evaluation system.
