Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0026] The visualization method of the knowledge pedigree of the present invention is divided into two stages of data preprocessing and visualization of the knowledge pedigree. The principle is:

[0027] In the data preprocessing stage, first extract the knowledge points and time attributes in the literature data, then divide the extracted knowledge points according to the time slice method, and finally count the occurrence times of knowledge points and the co-occurrence times between knowledge points;

[0028] In the visualization stage of the knowledge pedigree, first determine the pedigree relationship between it and the target knowledge point according to the age of all the knowledge points that have a co-occurrence r...

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.

Description

technical field [0001] The invention belongs to the technical field of information processing, and in particular relates to a visualization method for organizing and displaying knowledge pedigree of knowledge points and development context in a professional field by using age and knowledge co-occurrence relationship. Background technique [0002] Scientific research activities are based on the collection, collation and accumulation of existing knowledge, focusing on the exploration and study of the unknown world. The creation, dissemination and use of knowledge play an increasingly prominent role in promoting scientific and economic development, and the 21st century has gradually entered the stage of knowledge economy. The specific performance is: on the one hand, scientific and technological knowledge is constantly increasing and deepening, and the breadth and depth of knowledge have reached an unprecedented level; on the other hand, with the improvement of social division ...
