Knowledge Fusion Method Based on Dynamic Ontology in Cloud Manufacturing Mode

Abstract

A knowledge fusion method based on dynamic ontology in the cloud manufacturing mode belongs to the research content of modern manufacturing technology in the field of advanced manufacturing technology. This method provides a solution for the integrated application of distributed heterogeneous resources in the cloud manufacturing mode. This method forms fusion knowledge resources based on dynamic ontology constructed by multi-domain ontology. First, carry out semantic analysis and analysis on the knowledge requirements to obtain domain term keywords; then find relevant ontology fragments from the multi-domain ontology according to the keywords, and reorganize these ontology fragments to form a dynamic ontology; on this basis, use dynamic ontology terminology Analyze the knowledge resources hidden in the document, obtain the knowledge fragments represented by paragraphs, calculate the themes of the knowledge fragments, and associate them with the dynamic ontology to form a fusion knowledge resource. To a certain extent, the present invention realizes unified access and management of multi-source heterogeneous knowledge resources distributed in group enterprises, realizes dynamic fusion of knowledge resources, and effectively adapts to continuous update and change of enterprise knowledge resources and knowledge requirements.

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
