Embodiment Construction

[0018] Please refer to the attached picture As shown, the following introduces in detail the knowledge constructed using the present invention picture The specific implementation process of Spectrum Man-tree for knowledge management and pushing core algorithms:

[0019] Step 1: Generate Manufacturing Design Knowledge Base

[0020] The inventors selected 210 knowledge topics (called manufacturing topics) in the automotive body design process. These themes are the most frequently used themes in the application history of designers of a certain domestic automobile manufacturer. Therefore, it can be said that these topics are important topics of interest to users. These selected topics include: overall body design, body modeling , body hard point size, body structure, automotive wind tunnel, etc. database by keyword from each number picture The relevant page data downloaded from the library and crawled from the Web, a total of 230,942 documents

[0021] Step 2: Extract kno...

Abstract

The invention belongs to the technical field of knowledge management and knowledge pushing oriented to manufacturing enterprises, particularly relates to a novel and efficient knowledge management and knowledge pushing method based on a knowledge graph and discloses a knowledge pushing method based on a manufacturing design knowledge graph structure (Man-tree). By means of the method, the comprehensiveness and accuracy of enterprise knowledge pushing can be effectively improved. The knowledge pushing method comprises the step that a knowledge modeling module, a knowledge extracting and subject discovering module, a knowledge graph Man-tree establishing module, a user knowledge possess degree calculation module and a knowledge pushing module are established by introducing an LDA method. By quantitatively evaluating the degree of the knowledge processed by a user, the knowledge graph is expanded, and semantic association between knowledge and the user is established. According to the specific technology, formation of a database, extraction of knowledge, discovery of knowledge association, knowledge storage design, and a quantitative calculating method for the degree of the knowledge processed by a user are included. The novel method for knowledge pushing in the manufacturing design field is given on the basis that the manufacturing design graph is proposed.

Description

technical field [0001] The invention belongs to the technical field of product design knowledge management and knowledge push for manufacturing enterprises, and specifically relates to a novel and efficient knowledge-based picture Spectrum's knowledge management and push method can effectively improve the accuracy and completeness of enterprise knowledge push. Background technique [0002] as national The pillar industry of the economy, the manufacturing industry is the leading sector of my country's economic growth and the foundation of economic transformation; as an important support for economic and social development, the manufacturing industry is the main channel for urban employment in my country and the concentrated expression of international competitiveness. Manufacturing directly reflects a nation The level of productivity that differentiates developing nation and hair Developed country important factor is national The material basis of the economy and th...
