Knowledge fusion method based on dynamic body in cloud manufacturing mode

Abstract

The invention provides a knowledge fusion method based on a dynamic body in a cloud manufacturing mode and belongs to research contents of modern manufacturing technologies in the technical field of advanced manufacture. The method is a solution method for integrated application of heterogeneous resource distributed in the cloud manufacturing mode and is based on the dynamic body established by a multi-field body to form fused knowledge resources. The method comprises the steps of firstly performing semantic analysis on knowledge demand, obtaining field term key words; then finding relevant body segments from the multi-field body according to the key words, and restructuring the body segments to form the dynamic body; utilizing dynamic body terms to analyze the knowledge resources implied in files on the basis so as to obtain knowledge fragments with paragraphs as representations, calculating themes of the knowledge fragments, enabling the themes to be associated with the dynamic body to form the fused knowledge resources. By means of the method, unified access and management on multi-source heterogeneous knowledge resources distributed in group enterprises is achieved to some degree, dynamic fusion of existing knowledge resources is achieved, and continuous update and change of knowledge resources and knowledge demands of the enterprises are effectively met.

Description

technical field [0001] The invention relates to a dynamic ontology-based knowledge fusion method in a cloud manufacturing mode, which belongs to the research content of knowledge resource management and application methods in the field of computer application technology. Background technique [0002] Cloud manufacturing is to learn from the idea of ​​cloud computing and the concept of "manufacturing as a service", replace "manufacturing resources" with "computing resources", virtualize various manufacturing resources and service-oriented manufacturing capabilities, and provide active (active) services for manufacturing enterprises. ), agile, aggregative, and all-aspects manufacturing resources and manufacturing capability services to realize wide-area interconnection and on-demand sharing of manufacturing resources. Cloud manufacturing adopts the cutting-edge concepts of contemporary information technology, including cloud computing, and supports the manufacturing industry t...

Problems solved by technology

[0003] However, the heterogeneous distribution of knowledge resources is prominent: on the one hand, the distribution of knowledge resources is scattered in different enterprises and departments, which is implicit in the models, documents, normative standards of previous products, and the minds and experiences of experts in related fields; On the one hand, traditional knowledge bases solidify knowledge resources and then search for matching knowledge according to needs. Although their relatively fixed expression and storage methods can meet knowledge needs to a certain extent, many knowledge bases are independently designed for specific applications. Sex and pertinence and integration are limited
