Introduction to Domain-Driven Data Mining Special Section

In the last decade, data mining has emerged as one of the most dynamic and lively areas in information technology. Although many algorithms and techniques for data mining have been proposed, they either focus on domain independent techniques or on very specific domain problems. A general requirement in bridging the gap between academia and business is to cater to general domain-related issues surrounding real-life applications, such as constraints, organizational factors, domain expert knowledge, domain adaption, and operational knowledge. Unfortunately, these either have not been addressed, or have not been sufficiently addressed, in current data mining research and development.Domain-Driven Data Mining (D3M) aims to develop general principles, methodologies, and techniques for modeling and merging comprehensive domain-related factors and synthesized ubiquitous intelligence surrounding problem domains with the data mining process, and discovering knowledge to support business decision-making. This paper aims to report original, cutting-edge, and state-of-the-art progress in D3M. It covers theoretical and applied contributions aiming to: 1) propose next-generation data mining frameworks and processes for actionable knowledge discovery, 2) investigate effective (automated, human and machine-centered and/or human-machined-co-operated) principles and approaches for acquiring, representing, modelling, and engaging ubiquitous intelligence in real-world data mining, and 3) develop workable and operational systems balancing technical significance and applications concerns, and converting and delivering actionable knowledge into operational applications rules to seamlessly engage application processes and systems.

Informalilty in the Social and Culture Life in the City Centre of Nairobi

We live in a world of advanced technology, stiff global competition and rapid transformation of all facets of life and as a result architecture has not been spared. These transformations affect the social relations, cultural consumption and political economy that have influenced the manner in which people perform in and out of space in the city centres. The residents have adopted strategies for negotiating through the spaces sanitized by authorities and other agents. The public spaces provide the background materials for informal urban practices that are sometimes deemed illegal yet are necessary for animating the city spaces. Cities market themselves ecstatically beyond the baroque with a more visible presence of the contending parties through trademarks, public relations invasively advertised in streets, monuments (signature buildings or projects), and language. This paper comes out of a research carried out in Nairobi in February and March 2007. It examined how the notions of globalisation are reflected in the life in the city centre; the impacts on the quality of life of users of the city centre and how informal urbanism has developed as copying strategy to deal with the transformations due to liberalization and globalization.

Creating Shared Public Space in the Contested City: The Role of Urban Design

This paper examines relevant characteristics of the ‘contested city’ and the concept of ‘public space’ in that problematic context. It offers an appraisal of the historical and contemporary role of urban design in shaping social space and interrogates the feasibility of using urban design to facilitate more integrated cityscapes. It presents detailed case studies of two ‘contested cities’, Nicosia and Belfast, based on content analysis of policy and planning documents, extensive site analyses in both places, interviews and seminar discussions with policy makers, planners, community and civic leaders. The paper comprises four dimensions—conceptual, descriptive, analytical and prescriptive—and in its final section identifies core values and relevant policies for the potential achievement of shared space in contested cities.

Agitating for a design and regeneration agenda in a postconflict city: the case of Belfast

Introduction

Belfast has been a focus of academic attention for the last forty years with most interest centred on various aspects of ‘the Troubles’. Where there has been interest in the built environment, it has largely been about how the ‘security situation’ impacted directly on architecture and on the design and layout of social housing. This paper seeks to go beyond this to explore how the political- administrative culture of ‘the Troubles’ interacted with ‘normal’ market forces to shape the central area of the city, and to consider the responses of a recently formed activist group, known as the Forum for Alternative Belfast (hereafter referred to as the Forum). The paper is written by three of the directors of the Forum.1 Moreover, the empirical research presented here was undertaken by the Forum as part of a campaign to address issues relating to the design, layout and quality of Belfast’s built environment. In the longstanding tradition of participant observation working within an action-research paradigm, the participants have attempted to offer an account that is evidentially and purposefully selfcritical and reflective. It is of course recognised that while this approach offers many positive attributes, such as phenomenological access through immersion in the project, it also has the potential to bring compromise on research detachment and objectivity.2 To address the latter, the authors have attempted
to avoid polemical argument, and to support claims with primary or secondary research evidence. The authors also acknowledge that action-research has a chequered history; however, they would argue
that their approach is faithful to a concept that sees ‘research’ defined as understanding and ‘action’ defined as seeking change. The Forum’s very purpose is to seek change, but to do this requires evidence, collaboration and demonstration. And in this sense, it is a learning process for all participants, including the research activists, government officials, community organisations and students. The authors also recognise the complexity of factors that affect urban management and change, particularly in a city such as Belfast, which has had to cope with political violence for over thirty years. And they appreciate that in the context of conflict, governance is skewed to cope with political realities. Hamdi reminds us, however, that in practice there is an ‘important dialectic between top-down planning, with its formal and designed laws and structures, and bottom-up selforganizing collectivism—those “quantum and emergent systems” which Jane Jacobs argued long ago give cities their life and order.’3

New York City: 12 December, 1980

This article compares two documentary treatments of the Central Park vigil for John Lennon in 1980: Happy Birthday to John (Jonas Mekas, 1995, 16mm, 18 min.), and Dix minutes de silence pour John Lennon/Ten Minutes Silence for John Lennon (Raymond Depardon, 1980, 16mm, 10 min.). Mekas and Depardon might seem an improbable combination but as the article demonstrates there are affinities, if not direct points of convergence, in outlook and documentary method: both sensibilities have been shaped by migrant experiences, and much of their work, for all its formal and structural differences, is preoccupied with experiences of exile and displacement, rootedness and the meaning of home, the country and the city (and in Mekas’s case, the country in the city). Mekas and Depardon are also Europeans who have developed an intimate social and artistic relationship with New York City; both are concerned with the place of autobiography in their work, using captions, inter-titles, diary entries, photographs, and 1st person commentary to complicate relations between the imaginary and the documentary. In addition to discussing the significance of these preoccupations, and differences in the manner in which both filmmakers witness the apotheosis of Lennon as cultural martyr (and natural New Yorker), the article also examines the phenomenon of public mourning, and how it often displaces its ostensible subject: associatively, in the case of Mekas; incidentally, in the case of Depardon; and intentionally, in the case of the mass media, and popular culture.
