In complex industrial processes, the knowledge has properties of multi-source heterogeneity, polymorphism, and uncertainty. When the conventional knowledge representation methods are used to represent this type of knowledge, they often result in misunderstanding, inexplicability, and ambiguity. To solve this problem, a semantic network based on intuitionistic fuzzy directed hyper-graphs (SN-IFDHGs)...
This paper presents a framework for reasoning about the semantic impact of aspect weaving at the level of early design modeling. The framework is based on semantic consistency between a model and its projection in the woven model. If a weaving preserves the semantic consistency between the model and its projection, then it has no impact on the model. The underlying formalisms are Process Algebras...
Case feature weights are the keys to affecting the retrieving in case-base reasoning. To solve the problems of the existing algorithms such as poor objectivity and high complexity, a method based on coverage for determining the case feature weights is proposed, which calculates the case feature weights by the affecting of each attribute to the case average coverage. This algorithm has been applied...
