中文摘要:
      高校教师的业绩数据对于教师的考核评优、薪资提升、岗位聘任和职称晋升等人事决策具有十分重要的作用。针对其兼具复杂层次特征和多维属性的特点,提出了一种基于圆形嵌套图和平行坐标的VPM(Venn Parallel Coordinates Mixing)混合可视化方法。该方法首先采用基于D3布局算法的圆形嵌套图表示层次结构,而后划分叶子节点的圆周为不同的属性轴,通过布局设计、属性映射、属性点连接及缩放、高亮等用户交互来实现层次结构中多维属性的可视化。将该方法用于教师业绩数据,实现了对学院、研究所、教师各层级结构的可视化,可清晰展示数据项的细节信息。实验结果表明,提出的VPM方法能有效地展示教师的业绩数据,评价结果亦符合实际情况,能帮助系统用户——院校管理者对教师进行更好的管理及业绩考核。
英文摘要:
      The performance data of college teachers play an important role in the evaluation of teachers,such as assessment and evaluation,salary increasement,job appointment and promotion of professional titles.Aiming at the characteris-tics of complex hierarchical features and multi-dimensional attributes,this paper proposed a VPM (Venn Parallel Co-ordinates Mixing) hybrid visualization method based on circular nested graphs and parallel coordinates to visualize the performance data of college teachers.The method uses a circular nested packed graph based on D3 layout algorithm to represent the hierarchical structure,and then divides the circumference of the leaf nodes into different attribute axes,rea-lizing visualization of multi-dimensional attributes by user interaction such as layout design,attribute mapping,attri-bute point connection,scaling and highlighting.The method is applied to the teacher performance data,realizing the visua-lization of the hierarchical structure of the college,the research institute and the teacher,and clearly displaying detailed information of the data item.The experimental results show that the proposed VPM method can effectively display teachers’ performance data.The data and evaluation results are also in accordance with the actual situation,which can help the administrators to manage and evaluate teachers in a better way.
