Analogy Mining for Specific Design Needs

Finding analogical inspirations in distant domains is a powerful way of solving problems. However, as the number of inspirations that could be matched and the dimensions on which that matching could occur grow, it becomes challenging for designers to find inspirations relevant to their needs. Furthermore, designers are often interested in exploring specific aspects of a product-- for example, one designer might be interested in improving the brewing capability of an outdoor coffee maker, while another might wish to optimize for portability. In this paper we introduce a novel system for targeting analogical search for specific needs. Specifically, we contribute a novel analogical search engine for expressing and abstracting specific design needs that returns more distant yet relevant inspirations than alternate approaches

What does semantic tiling of the cortex tell us about semantics?

Recent use of voxel-wise modeling in cognitive neuroscience suggests that semantic maps tile the cortex. Although this impressive research establishes distributed cortical areas active during the conceptual processing that underlies semantics, it tells us little about the nature of this processing. While mapping concepts between Marr's computational and implementation levels to support neural encoding and decoding, this approach ignores Marr's algorithmic level, central for understanding the mechanisms that implement cognition, in general, and conceptual processing, in particular. Following decades of research in cognitive science and neuroscience, what do we know so far about the representation and processing mechanisms that implement conceptual abilities? Most basically, much is known about the mechanisms associated with: (1) features and frame representations, (2) grounded, abstract, and linguistic representations, (3) knowledge-based inference, (4) concept composition, and (5) conceptual flexibility. Rather than explaining these fundamental representation and processing mechanisms, semantic tiles simply provide a trace of their activity over a relatively short time period within a specific learning context. Establishing the mechanisms that implement conceptual processing in the brain will require more than mapping it to cortical (and sub-cortical) activity, with process models from cognitive science likely to play central roles in specifying the intervening mechanisms. More generally, neuroscience will not achieve its basic goals until it establishes algorithmic-level mechanisms that contribute essential explanations to how the brain works, going beyond simply establishing the brain areas that respond to various task conditions

Taking things into account: learning as kinaesthetically-mediated collaboration

This paper presents research on participant learning processes in challenge course workshops using the framework known as Cultural-Historical Activity Theory (CHAT). CHAT views learning as a shared, social process rather than as an individual event. Participants\u27 experiencing and learning was mediated by the physical and social conditions of the experience and by the contributions of other participants. The concept of mediation suggests that the meaning participants make of experience is not an individual event, but instead is enacted as a creative, collaborative process using cultural and institutional tools. The recognition that people\u27s physical, social and reflective learning processes are mediated, challenges longstanding assumptions about the radical autonomy of learners, about ‘direct experience,’ and about the centrality of independent, cognitive reflection in experiential learning. Empirical data showing processes of mediation are presented, and the implications for research and theory are discussed

Objects, actions, and images: a perspective on early number development

It is the purpose of this article to present a review of research evidence that indicates the existence of qualitatively different thinking in elementary number development. In doing so, the article summarizes empirical evidence obtained over a period of 10 years. This evidence first signaled qualitative differences in numerical processing, and was seminal in the development of the notion of procept. More recently, it examines the role of imagery in elementary number processing. Its conclusions indicate that in the abstraction of numerical concepts from numerical processes qualitatively different outcomes may arise because children concentrate on different objects or different aspects of the objects, which are components of numerical processing

Achilles And The Tortoise: Some Caveats To Mathematical Modeling In Biology

Mathematical modeling has recently become a much-lauded enterprise, and many funding agencies seek to prioritize this endeavor. However, there are certain dangers associated with mathematical modeling, and knowledge of these pitfalls should also be part of a biologist\u27s training in this set of techniques. (1) Mathematical models are limited by known science; (2) Mathematical models can tell what can happen, but not what did happen; (3) A model does not have to conform to reality, even if it is logically consistent; (4) Models abstract from reality, and sometimes what they eliminate is critically important; (5) Mathematics can present a Platonic ideal to which biologically organized matter strives, rather than a trial-and-error bumbling through evolutionary processes. This “Unity of Science” approach, which sees biology as the lowest physical science and mathematics as the highest science, is part of a Western belief system, often called the Great Chain of Being (or Scala Natura), that sees knowledge emerge as one passes from biology to chemistry to physics to mathematics, in an ascending progression of reason being purification from matter. This is also an informal model for the emergence of new life. There are now other informal models for integrating development and evolution, but each has its limitations

Development of bambangan (Mangifera pajang) carbonated drink

Mangifera pajang Kostermans or bambangan is a popular fruit among Sabahan due to its health and economic values. However, the fruit is not fully commercialized since it is usually been used as traditional cuisine by local people. Thus, development of bambangan fruit into carbonated drink was conducted to produce new product concept. The objectives of this study were to conceptualize, formulate, evaluate consumer acceptance, and determine physicochemical properties and nutritional composition of the accepted product. Method used in conceptualising the product was based on questionnaire. The consumer acceptance was evaluated based on descriptive and affective tests with four product formulations tested. The physicochemical properties on carbon dioxide volume, colour, pH, total acidity, total soluble solid (TSS) and viscosity were highlighted, meanwhile nutritional composition on fat, protein, carbohydrates and energy content were determined. About 77% respondents gave positive feedback, and 69% respondents decided this product is within their budget. The formulation of 5% bambangan pulp, 70% water, 25% sugar and 0.2% citric acid was highly accepted in descriptive and affective tests with 4.4 and 6.39 mean scores, respectively. The physicochemical properties and nutritional composition of the acceptance product were in optimum value except for colour, total acidity and TSS. Overall, this study showed that the product has high potential to be commercialized as new product concept, and heritage of indigenous people can be preserved when this fruit is known regionally

Meaning through Metaphor: Visual Dialogue and the Picturing of Abstraction

This synthesis builds on the connections between language and cognition, and the parallel sub-domains of linguistic metaphor and visual knowledge representation, to argue that traditional dialogue processes might aptly be employed to help collaborative learners examine complex abstractions. The starting premise, that habitual language-embedded metaphor may be used as a window into the understanding of abstractions, such as tolerance, education, justice, and integrity derives from the important work of Lakoff and Johnson in developing their Embodiment Theory of Metaphor. Further parallels for what is thought of in cognition as the spread of activation are considered in tandem with theories about the spread of connection-making in creative thinking. A look at the works of Isaacs and Bohm, both pioneers in theories of dialogue process, leads directly to the proposal that dialogue, with slight modification, could provide an effective atmosphere for capitalizing on the linguistic metaphor-visual knowledge relationship. Pulling together all of these connections, the paper proposes the principles of what the author calls visual dialogue. Visual dialogue is a collaborative framework within which learning participants might focus on the details of the metaphoric thinking embedded in their language, “seeing,” as a result the abstract knowledge represented by their mental imagery. Within the atmosphere of a visual dialogue, it is argued, deeper and more subtle understandings of abstractions may be revealed collaboratively, or perhaps even re-constituted into new meanings. Understanding or meaning built in this way may then be used to approach more practical problems systematically, though such systems are not described in this paper. The paper concludes by considering a number of issues raised by the notion of thinking about, or visualizing, complex social abstractions via the process of visual dialogue. Among these are: the philosophic implications of examining implicit ambiguity metaphorically; the practical use of dialogue processes that are often thought of as open-ended; the application of visual dialogue to different age groups; the potential for the use of other media (music, sculpture, etc.) in examining abstraction; and thoughts on the use of creativity in visual dialogue for promoting potential problem solving strategies or approaches

Knowing with Images: Medium and Message*

Problems concerning scientists’ uses of representations have received quite a bit of attention recently. The focus has been on how such representations get their contents and on just what those contents are. Less attention has been paid to what makes certain kinds of scientific representations different from one another and thus well suited to this or that epistemic end. This article considers the latter question with particular focus on the distinction between images and graphs on the one hand and descriptions and related representations on the other

Indexing, browsing and searching of digital video

Video is a communications medium that normally brings together moving pictures with a synchronised audio track into a discrete piece or pieces of information. The size of a “piece ” of video can variously be referred to as a frame, a shot, a scene, a clip, a programme or an episode, and these are distinguished by their lengths and by their composition. We shall return to the definition of each of these in section 4 this chapter. In modern society, video is ver
