| Abstract:Knowledge graph, also known as scienti c knowledge graph, can reveal the
dynamic development rules in complex knowledge elds. How to clearly present the
internal structure of knowledge graph is particularly important, however, the current
visualization research based on knowledge graph is rare. In this paper, varieties of data
related to education are mined from massive web data, and are fused together. Then
knowledge graph which is centered on educational events is constructed utilizing extracted
named entities and entity relations. We construct a visual analysis platform for education
knowledge graph, EduVis, which can support users to do associated analysis of education,
and enable users to obtain the public opinions. In EduVis, we design and implement a) a
word cloud treemap to provide an overview of education knowledge graph, b) a layout of
events relation network graph based on topological structure and timeline to explore in
details, c) a click tracking path to record the history of users' clicks and help users to
backtrack. The case studies show that the aforementioned visual analysis methods for our
knowledge graph can meet users' demands for data analysis tasks. |
