It explores the nature of cultural products and concludes that there are commonalities in them at an ontological level, giving rise to cultural product ontology. Such an ontology provides a solid foundation for the development of the expected design theory. On the other hand, this research study regards functional reasoning of conceptual design as the theoretical reference for the formation of the expected design theory. This is because its design process is very similar to the creative processes of different cultural products that can also be described by the concepts of homeomorphism, a scientific account. Furthermore, the expected design theory works at a domain level, while conceptual design theories operate at a conceptual level. This research study, therefore, refers to Sloman’s two systems of reasoning and defines the expected design theory as a sub-conceptual design theory, namely, Conceptual Recombination. To connect Conceptual Recombination with cultural product ontology, this research study refers to the task model of application ontology to define their working relationship, since there is no method ontology in cultural product ontology due to the fact that there is not yet a commonly agreed creative method for different cultural product creations. Furthermore, there is a computational representation of Conceptual Recombination to demonstrate the operations and contributions of Conceptual Recombination as well as to provide a reliable creative method for the generation of exploratory and transformational creativity (ET-creativity) in the different parts of cultural products through a single-user Creativity Support Tool that takes in user unfinished work and produces representational and creative system vi outputs as continuations to the user input. Such a computational representation clearly explains the three levels of prediction of Conceptual Recombination that are in response to the concepts of functional reasoning. In addition, since Conceptual Recombination is also a prescriptive model, there is no proof of it. Instead, this research study uses cases to demonstrate its operations to reveal its contributions to cultural product creation. It concludes that Conceptual Recombination defines a new research area as regards sub-conceptual design theory and an objective creative method for different cultural product creations and the above-mentioned single-user CSTs. vii Publication Hung, E.

Knowledge- Based Systems, 53, 1-12. viii Acknowledgements I sincerely thank my main supervisor Clifford S. T. Choy to let me start and complete this research study. Since my master’s degree, Clifford has been giving me advice on my academic development. Especially when I had a difficulty in starting my Ph.D., his help was the most truthful. During my study, Clifford was very considerate about my full-time overseas teaching. My completion of this dissertation would not be possible without his sincere advice and understandings. Also, I would like to thank my co-supervisor Tang Ming Xi for pinpointing the importance of connecting my work with design together. It does have a much more complex connotation than what I knew in the past. Last but not least, I would like to thank the administration office of School of Design for providing me with the necessary information to smooth out my study. ix Table of Contents Abstract v Publications vii List of Tables xiv List of Figures xvi 1 Introduction 1 1.1 The Problem Domain and Approach………………………………. 5 1.2 Motivations and Applications…………………………………….... 6 1.3 Thesis Statement………………………………………………….... 7 1.4 Research Objectives and Scope……………………………………. 8 1.5 Original Contributions……………………………………………... 8 1.6 Dissertation Outline………………………………………………... 9 2 Literature Review 14 2.1 Overview………………………………………………………….... 14 2.2 Cultural Products……………………………………………..……. 15 2.2.1 Ontologies in Cultural Products...………………………….. 19 2.3 Conceptual Design Theories……………………………………….. 20 2.3.1 C-K Design Theory – A Conceptual Design Theory with a Creative Model……………………………………………... 26 2.3.2 Creativity in Conceptual Design…………………………… 28 2.4 Creativity Support Tools…………………………………………… 29 2.4.1 Computational Creativity…………………………………... 30 2.4.2 Defining CST………………………………………………. 33 2.4.3 The Applications of ET-creativity in CSTs………………... 35 2.5 Summary…………………………………………………………… 36 x 3 Methodology 39 3.1 Overview………………………………………………………….... 39 3.2 Prescriptive Model of Design…….………………………………... 40 3.3 Abduction in Design……………………………………….………. 42 3.4 Conceptual Design Theories with Prescriptive Models and Abductive Reasoning…………………...………………………….. 43 3.5 The Necessary Conditions for the Computational Representation of the Expected Design Theory……………………………………..… 46 3.6 Summary…………………………………………………………… 46 4 Conceptual Recombination as a Sub-conceptual Design Theory 49 4.1 Overview…………………………………………………………… 49 4.2 Conceptual and Sub-conceptual Levels……………………………. 50 4.3 Conceptual Recombination as a Sub-conceptual Design Theory….. 54 4.4 Summary…………………………………………………………… 54 4.4.1 Propositions for the Formation of Conceptual Recombination……………………………………………... 54 5 The Theoretical Framework of Conceptual Recombination 56 5.1 Overview………………………………………………………….... 56 5.2 Cultural Product Ontology…………….…………………………… 57 5.2.1 The Four Ontological Properties…………………………… 57 5.2.2 The Key Axiom…………………………….………………. 59 5.2.3 Yoshikawa’s General Design Theory……………………… 60 5.3 Conceptual Recombination as a Task Model for Cultural Product Ontology………………………………………………………….... 63 5.4 Preparing for the Computational Representation of Conceptual Recombination……………………………………………………... 66 xi 5.4.1 Cultural Product Ontology in a Single-user CST………….……………………………………………... 66 5.4.2 The Relation between Cultural Product Ontology and Conceptual Recombination in a Single-user CST………….. 67 5.4.3 The Conceptual Space for the Computational Representation of Conceptual Recombination……………... 68 5.4.4 The Application of ET-creativity…………………………... 70 5.5 Summary…………………………………………………………… 70 5.5.1 Propositions for the Formation of Conceptual Recombination……………………………………………... 71 6 The Operations of the Computational Representation of Conceptual 73 Recombination 6.1 Overview………………………………………………………….... 73 6.2 Conceptual Recombination as a Task Model for Cultural Product Ontology…………………………………………………………… 74 6.2.1 The Deconstruction Stage………………………………….. 75 6.2.2 The Reconstruction Stage………………………………….. 77 6.3 ET-creativity in Conceptual Recombination………………………. 84 6.4 Conceptual Recombination as a Sub-conceptual Design Theory with ET-creativity………………………………………………….. 87 6.5 Summary………………………………………………………….... 88 6.5.1 Propositions for the Formation of Conceptual Recombination……………………………………………... 89 7 Defining Computational Model for Conceptual Recombination 92 7.1 Overview………………………………………………………….... 92 7.2 Wiggins’s Creative Systems Framework…………………………... 93 xii 7.3 The 7-tuple Computational
