Design And Implementation Of Personal Knowledge Management Platform Based On Knowledge Graph

Knowledge graph is a kind of structured semantic knowledge base.It describes the knowledge resources and its carrier via graphical style,and presents the core structure,evolution history,association relationship and overall structure of knowledge through the visualization of the graph.In recent years,with the rapid development of information technology and computer technology,knowledge graph has been gradually applied to different fields,such as business,scientific research and education.The purpose of this paper is to design and implement a personal knowledge management platform based on knowledge graph,which mainly provides users with functions as knowledge graph construction,knowledge graph display,knowledge graph analysis and community sharing.This paper takes personal notes as the starting point,analyze the contents of notes via natural language processing technology,automatically extract attributes and construct the knowledge graph of notes on the basis of relationship between attributes;complete the visualization of knowledge graph through D3.js and other visual tools;analyze the user notes with statistical analysis technology to generate user knowledge portraits;as for community sharing,a personalized community is realized by using the recommendation algorithms of content-based and collaborative filtering;Finally,implement related content management functions by combining front-end and server development technology,and the platform is evaluated and improved through testing.Based on knowledge graph and natural language processing technology,this paper designs and implements a complete functional personal knowledge management platform,which provides a new idea for constructing and displaying the knowledge graph of personal learning domain.
