The Multidimensional Modeling Method of Design Cognition Based on Semantic Link

The complex design cognition and concept evolution limited to process research, is involved in the problem of ambiguity and uncertainty analysis. From the perspective of cognitive semantic reasoning and link representation, a deep mining on understanding design process is conducted by using the semantic links as the representation of design cognition information. On the basis of these, a multi-dimensional cognitive model which integrates data links, process links and conceptual links is proposed by emphasizing on the cognitive communication text information. The model using matrix to storage semantic link data processes unstructured data of design cognition. Though analyzing the link node entropy obtained by merging the uncertain information theory, T-code coding method and linkography, the complexity of the design cognition process is evaluated to realize the capture of key innovative concepts and analysis of switching design intention. On the aspect of non-sequential concept space relations, the semantic ne
