    Knowledge data discovery and data mining in a design environment

    Designers, in the process of satisfying design requirements, generally encounter difficulties in, firstly, understanding the problem and secondly, finding a solution [Cross 1998]. Often the process of understanding the problem and developing a feasible solution are developed simultaneously by proposing a solution to gauge the extent to which the solution satisfies the specific requirements. Support for future design activities has long been recognised to exist in the form of past design cases, however the varying degrees of similarity and dissimilarity found between previous and current design requirements and solutions has restrained the effectiveness of utilising past design solutions. The knowledge embedded within past designs provides a source of experience with the potential to be utilised in future developments provided that the ability to structure and manipulate that knowledgecan be made a reality. The importance of providing the ability to manipulate past design knowledge, allows the ranging viewpoints experienced by a designer, during a design process, to be reflected and supported. Data Mining systems are gaining acceptance in several domains but to date remain largely unrecognised in terms of the potential to support design activities. It is the focus of this paper to introduce the functionality possessed within the realm of Data Mining tools, and to evaluate the level of support that may be achieved in manipulating and utilising experiential knowledge to satisfy designers' ranging perspectives throughout a product's development

    Visualisation of Perception of Experiential Activities in Business and Administration and Economy

    This paper explores how to incorporate information visualization tools into qualitative studies to represent the underlying structure of knowledge. Information visualization plays a key role in many areas such as decision-making, data mining, market studies, or knowledge management. A case of experiential learning was developed for Quantitative Techniques in Business and Administration and Economy Degrees at the University of Granada, Spain. The goal is to analyze the opinion of students (n = 227) on the development of the activity through information visualization techniques. The gathered information was subjected to a categorization process to unify and homogenize the responses. After a term-clumping process, a co-word analysis using the VosViewer software is used to analyze the relationships among terms and provide the network maps. Results display the main associations and clusters of terms used when assessing the experiential activity, using qualitative techniques. In conclusion, the strengths of data visualization enabling a better understanding of data for qualitative studies are established

    NOUS: Construction and Querying of Dynamic Knowledge Graphs

    Get PDF
    The ability to construct domain specific knowledge graphs (KG) and perform question-answering or hypothesis generation is a transformative capability. Despite their value, automated construction of knowledge graphs remains an expensive technical challenge that is beyond the reach for most enterprises and academic institutions. We propose an end-to-end framework for developing custom knowledge graph driven analytics for arbitrary application domains. The uniqueness of our system lies A) in its combination of curated KGs along with knowledge extracted from unstructured text, B) support for advanced trending and explanatory questions on a dynamic KG, and C) the ability to answer queries where the answer is embedded across multiple data sources.Comment: Codebase: https://github.com/streaming-graphs/NOU

    An Ethnography of Entanglements: Mercury’s Presence and Absence in Artisanal and Small-scale Gold-mining in Antioquia, Colombia

    Get PDF
    This paper describes a ‘follow the thing’ methodology as applied to an ethnography of entanglements. This methodology allowed for a materially and politically nuanced understanding of Antioquia, Colombia’s response to mercury pollution. This pollution primarily originates from the Artisanal and Small-Scale Gold Mining (ASGM) industry where mercury is employed in the gold extraction process. In following the mercury, the authors experiment with an ethnography of entanglements. The paper discusses how they address the current lacunae in mining ethnographies by focussing on mining as ‘practice’, going past the provision of technical descriptions of mining and ethnographic descriptions of miners to an ethnography of mining. This ethnographic approach considers the politics of materiality and addresses a lack of attention to the impacts of the presence and absence of materials on social life. Various mining practices in Antioquia illuminate how entanglements between miners and mercury have been co-constitutive of particular modes of ASGM. The paper will also provide examples of ‘negative mercury entanglements’ where efforts have been made to extricate mercury from mining practices. Rather than creating a vacuum, these mercury absences have been generative of new contested symbolic and material arrangements including entrepreneurial and ‘responsible’ mining, debates over miners’ rights, and the creation of new political relationships between ASGM and large-scale mining companies.fals

    Oblique strategies for ambient journalism

    Get PDF
    Alfred Hermida recently posited ‘ambient journalism’ as a new framework for para- and professional journalists, who use social networks like Twitter for story sources, and as a news delivery platform. Beginning with this framework, this article explores the following questions: How does Hermida define ‘ambient journalism’ and what is its significance? Are there alternative definitions? What lessons do current platforms provide for the design of future, real-time platforms that ‘ambient journalists’ might use? What lessons does the work of Brian Eno provide–the musician and producer who coined the term ‘ambient music’ over three decades ago? My aim here is to formulate an alternative definition of ambient journalism that emphasises craft, skills acquisition, and the mental models of professional journalists, which are the foundations more generally for journalism practices. Rather than Hermida’s participatory media context I emphasise ‘institutional adaptiveness’: how journalists and newsrooms in media institutions rely on craft and skills, and how emerging platforms can augment these foundations, rather than replace them
