The design meta-intent information is a kind of information about design rationale for design intent objects such as features, parameters and constraints. Based on the design meta-intent representation model this paper explores an ontology-based semantic query and reasoning method for design meta-intent information. A Jena-based semantic query process framework is presented. The user's queries for...
At present, traditional representation schemas of product design are short of expressions of explaining the representation of design intent so that understanding to product design intent and design reuse is affected. In this paper, a product design meta-intent concept is presented, and design intent objects, design meta-intents are analyze and summarized. An ontology-based framework to express design...
In order to make the semantic information of feature be shared and understood by computer, this paper discusses and analysis the semantic information of features, presents a semantic concept of feature. Based on description logic representations for semantic concepts of features and hierarchy structures are given. Based on the description logical reasoning of concept, a solution to realize automatic...
Modern feature-based CAD system can represent design intent with construction history, feature, parameterization and constraints. Until recently, standards for CAD data exchange among different CAD system were restrict to the exchange of pure geometrical information. This paper discusses the contents, formalization and characteristics of design intent of feature-based CAD models and the information...
