|Abstract:||This thesis explores the role of interpretation in design activity through the development of a computational model of constructive interpretation. It asks the question: how does the construction of interpretations from expectations within a situation affect design activity? This work hypothesises that designers construct their world from their expectations through interpretation. In interpreting their own work designers are able to make unexpected discoveries and explore the implicit knowledge held within their expectations of the world. These expectations are grounded in experience. A conceptual model for constructive interpretation is described. Knowledge held by designers is represented in a perceptual symbol system, in which knowledge organised in a hierarchy. Within this hierarchy, higher layers represent an increased level of abstraction. Knowledge is learnt through experience in an environment. The topmost layer in this hierarchy is the situation.Interpretation occurs through pull from the expectations. Expectations in a layer are changed by the layer above. The construction of expectations utilises knowledge about the world that the designer gains through experience. A computational framework for this conceptual model is described: (i) based upon conceptual spaces, where expectations within the situation perturb each other; and (ii) based upon a hierarchy of unsupervised learning networks, where prototypes represent convergence zones within conceptual space. Constructive interpretation is implemented in a number of demonstrations utilising modified self-organising maps linked together to represent layers in the conceptual model. Demonstrations show: (i) how situations are changed through construction from implicit expectations; (ii) how situations co-ordinate concepts through expectations that are grounded in experience; (iii) how construction from expectations produces stability in a chang ing environment; and (iv) how useful rather than accurate in! terpreta tions can be produced by constructing from expectations. A model of constructive interpretation in design is developed in which a system iterates through generation of designs from expectations and constructive interpretation. In one experiment an agent has experience with a number of floor plans. It uses its experience to draw in a design medium and interpret its own work. Through constructive interpretation from implicit expectations the situation changes leading to a new space of designs. It provides a model of the way that designers make unexpected discoveries within their work that are useful to the design task, through expectations, and relevant to the source, as the basis for constructing the interpretation. Another experiment uses sets of growth indicators about countries as concepts. The model shows how the space of designs changes through constructive interpretation and explores the effects of salience weighting upon the construction of interpretations. The work looks towards a situated model of design: a model of design that integrates interpretation, expectation and memory into the one cognitive framework. Constructive interpretation has applications for models of analogy and computational creativity. Future work in constructive interpretation is described.|
