Visualizing method for knowledge genealogy

Abstract

The invention discloses a visualizing method for knowledge genealogy, which comprises the following steps: extracting knowledge points and time attributes from literature data; performing year division on the knowledge points according to a time slicing method; counting appearing times of the knowledge points and co-occurrence times of the knowledge points; determining a genealogy relationship between the knowledge points and a target knowledge point according to years of all the knowledge points having a co-occurrence relationship with the target knowledge point; and finally arraying all the knowledge points on a time axis according to the years, so as to visually show a developing venation relationship between the knowledge points. According to the visualizing method for knowledge genealogy, a beginner in a professional field is assisted in searching and learning the valuable knowledge points from mass literature information and quickly and scientifically mastering the research topic and developing venation relationship contained in the literature, and the problem of inferior searching and learning effect caused by a user being short of professional background knowledge is solved.
