Due to lack of effective model representation, current MBD models cannot perform well in manufacturing reuse. In this paper, a new multilevel structuralized MBD model for manufacturing reuse is presented to capture the abstract information, topological information and machining semantic information involved. Firstly, the machining features considered as the machining semantic carriers are recognized...
Based on investigating challenges of product knowledge sharing in distributed environment, a context-sensitive product knowledge sharing architecture is proposed. Through a discussion of fundamental model for elucidating and characterizing context in knowledge sharing, and the mechanism of knowledge utilizing, annotating and clustering based on this knowledge context model, we present a context-sensitive...
Building ontology from scratch need identify the basic concepts, and their attributes and relationships. In terms of information integration, draft concepts, attributes and relationships can be directly captured by processing schemas of data sources. In this context, we present a hybrid semantic discovery approach, which is an extension of our previous work[1][2] to capture concepts, attributes and...
Modern product development needs a large number of knowledge contained at all stages of product life cycle. In order to deal with the discrete, heterogeneous expression, scenario dependence of various types of product knowledge, a context-driven knowledge-sharing approach is presented, covering product knowledge modeling, describing and organizing. Through building product knowledge context model,...
Based on a discussion of data understanding hierarchy, this paper reviews a state of the art of existing enterprise information integration solutions from semantic perspective. We divide existing approaches into three categories: programming semantic-based integration, syntax schema-based integration, and declarative semantic-based Integration, and evaluate the approaches in each category by comparing...
