The purpose of this article is to describe a new visualization framework for the analysis of hyperdimensional data. This framework was developed in order to facilitate the study of a new class of classifiers designated class cover catch digraphs. The class cover catch digraph is an original random graph technique for the construction of classifiers on high dimensional data. This framework allow...

The UK and wider international e-Research initiatives are entering a critical phase in which they need to move from the development of the basic underlying technology, demonstrators, prototypes and early applications to wider adoption and the development of stable infrastructures. In this paper we will review existing work on studies of infrastructure and community development, requirements eli...

Requirements elicitation is the first of the four steps in software requirements engineering (the others being analysis, specification, and validation). Software engineers use several elicitation techniques. To facilitate teaching these techniques, materials are provided to support an introductory lecture and four lectures on specific techniques: joint application design, brainstorming, intervi...

We introduce the sharing economy as an IT-enabled phenomenon that is distinct from existing socioeconomic modes of interaction. While research on the consumer perspective is growing, studies examining the complementary organizational perspective seem to be lagging behind. Our study therefore aims to investigate the firm stance by analyzing how successful sharing economy organizations manage the...

One problem that every presenter faces when delivering a public discourse is how to hold the listeners’ attentions or to keep them involved. Therefore, many studies in conversation analysis work on this issue and suggest qualitatively constructions that can effectively lead to audience’s applause. To investigate these proposals quantitatively, in this study we analyze the transcripts of 2,135 T...

Research continues to show that poor requirements elicitation leads to costly information systems failure. We also know that the most Information can be obtained by a consultant conducting conversations with clients. Research was conducted into consultants’ experience of these conversations. Twenty professionals involved in these conversations were interviewed and Phenomenographic analysis of a...

This paper explores the usefulness of robust Bayesian analysis in the context of an applied problem, 6nding priors to model judicial neutrality in an age discrimination case. We seek large classes of prior distributions without trivial bounds on the posterior probability of a key set, that is, without bounds that are independent of the data. Such an exploration shows qualitatively where the pri...

Current research into spatial audio has shown an increasing interest in the way subjective attributes of reproduced sound are elicited from listeners. The emphasis at present is on verbal semantics, however studies suggest that non-verbal methods of elicitation could be beneficial. Research into the relative merits of these methods has found that non-verbal responses may result in different eli...

An ORM based meta-schema, to represent various kinds of models of business processes, is discussed in this paper. Modeling of an enterprise as a series of business processes is gaining prominence with the emergence of new technologies such as the Internet. Enterprises are moving towards establishing well-described business processes within and across enterprises to include their customers and s...

Enterprise Resource Planning (ERP) systems often place huge demands on their users. The wide variety of functions and features offered throughout the system often lead to systems that are far from intuitive and may hinder efficient use. Moreover, many users need only a part of the functions to fulfill their work tasks effectively. Therefore, from the perspective of a specific user, providing al...
