    WEB services are software entities that have a well defined interface and perform a specific task. Typical examples include services returning information to the user, such as news or weather forecast services. A web service is formally described in a standardized language (WSDL). The service description may include the parameters associated with web services like input , output and quality of service. As web services and service providers proliferate, there will be a large number of candidate, and likely competing, services for fulfilling a desired task. Hence, effective service discovery mechanisms are required for identifying and retrieving the most appropriate services. The main contributions of our paper are summarized as follows; we propose and implement a method for determining dominance relationships among service advertisements that simultaneously takes into consideration multiple PDM criteria. We introduce a method for prioritization and clustering web services based on similarity measures using efficient algorithms Keywords : Web Service , PDM , dominance score ,TKDD, clustering

    Mass-participation Architecture: Social Media and the Decentralisation of Architectural Agency as a Commercial Imperative

    Full version unavailable due to 3rd party copyright restrictionsA key problem in the field of architecture and urban planning since the 1960s has been the marginal role played by the general public in directly shaping significant aspects of the built environment. This thesis draws on theories around participatory planning, and in particular, the seminal 1969 publication ‘Non-plan: An Experiment in Freedom’. Non-plan suggested the potential of digital technology to facilitate self-organising public participation in architectural design and urban planning, while also taking inspiration from consumer- responsive activities across commercial disciplines. Now, half a century later, advancing web-technologies are beginning to facilitate mass-participatory design as a commercial imperative, and nowhere is this trend more visible or revealing than in the development of consumer products. The aim of this thesis is therefore to use these developments in the consumer goods industry to investigate the implications and consequences of significantly decentralising architectural design agency through the use of social media. The thesis method is to undertake a comparative study of both the design disciplines of commercial architecture and consumer goods. Commercial architecture has inherited the selling imperative of the consumer goods industry; and, in this thesis, the commercial imperative towards mass-participatory consumer product design acts as a basis for a contemporary evaluation of architecture’s Non-plan theory. Throughout the research chapters interview content from notable architectural figures, as well as empirical exploration of mass-participatory design platforms, is combined with participatory planning theory and up-to-date information from relevant business and technology periodicals. Establishing a series of political and economic hurdles, as well as advantages to the emergence of mass-participation architecture, it is concluded that Non-plan’s free-market concept will come to present an increasingly viable approach to the practice of architectural design; given appropriate regulatory conditions, and against the backdrop of the rapidly developing culture and technologies encompassed by social media. In this context it is argued that architects will find themselves acting less as social interpreters, but more as stimulators, mediators and coordinators of a significantly larger, more insightful, and profoundly productive collective; one that is composed of participants from the general public

    Eliciting matters - controlling skyline sizes by incremental integration of user preferences

    Abstract. Today, result sets of skyline queries are unmanageable due to their exponential growth with the number of query predicates. In this paper we discuss the incremental re-computation of skylines based on additional information elicited from the user. Extending the traditional case of totally ordered domains, we consider preferences in their most general form as strict partial orders of attribute values. After getting an initial skyline set our basic approach aims at interactively increasing the system’s information about the user’s wishes explicitly including indifferences. The additional knowledge then is incorporated into the preference information and constantly reduces skyline sizes. In fact, our approach even allows users to specify trade-offs between different query predicates, thus effectively decreasing the query dimensionality. We give theoretical proof for the soundness and consistence of the extended preference information and an extensive experimental evaluation of the efficiency of our approach. On average, skyline sizes can be considerably decreased in each elicitation step

    Values and value in design

    Relatively little is known about how concepts of human values and value interact during the construction design process. Whilst researchers of value management have expounded in this context upon the complexity of the design process, problem-solving and sense-making, little is said about the alignment and reconciliation of multiple-stakeholder values and value judgements. An abductive reasoning and a grounded theory approach was adopted that iterated between literature and empirical observation to obtain new insights. The initial phase created a values and value framework and Value in Design (VALiD) approach through seven unstructured interviews, a design workshop, four Schwartz Values Surveys (with 545 participants) and 55 semi-structured interviews. The values and value parts were then separately implemented, developed and validated through action research on five live education capital projects, involving over 250 participants. Subsequently, a middle-range theory of values and value is proposed through theoretical triangulation. This draws on seven related theories to provide greater explanatory pluralism, uncover hidden phenomena and enable convergence. The research findings are significant in focusing soft value management on underlying stakeholder values and subjective value judgements. A more nuanced and intertwined relationship between stakeholder values, attitudes, behaviours and qualities during the design process is offered that promotes compromise and sense-making
