基于用户画像的学科评价研究——以一级学科航空宇航科学与技术为例

Research on Subject Evaluation Based on User Portrait:Taking First-Class Subject Aerospace Science and Technology as an Example

学科评价是学科建设的基础性工作和推动引擎,在学科发展中发挥着特有的评估作用、导向作用和激励作用。从学术贡献和研究热点两个维度构建学科画像评价模型,学术贡献维度选取综合性评价指标学术迹和学术矩阵,从宏观和微观层面评价学术产出特征。本研究首次将内容分析法引入学科评价,构建研究热点维度,通过关键词聚类分析,指出学科研究领域和研究特色。选取12所高校以一级学科航空宇航科学与技术为例进行实证研究,通过实证研究证实了所构建的学科画像评价模型既能深入揭示学术产出特征,又能反映学科的研究热点以及各校的优势学科。

Subject evaluation is the basic work and driving engine of subject construction,and it plays a unique role on evaluation,guidance and motivation in subject development.This paper constructs the subject portrait evaluation model from the two dimensions of academic contribution and research hotspot,and selects the comprehensive evaluation index ac⁃ademic trace and academic matrix from the academic contribution dimension to characterize the characteristics of academ⁃ic output from the macro and micro levels.For the first time,this research introduces content analysis into subject evalua⁃tion,constructs research hotspot dimensions,and points out subject research fields and research characteristics through keyword cluster analysis.This paper selects 12 universities to conduct empirical research taking the first-level discipline aerospace science and technology as examples.The empirical research confirms that the constructed subject profile evalua⁃tion model can not only reveal the characteristics of academic output,but also reflect the research hotspots of the subject and the superior subjects of each school.
