Publishing transaction data containing individuals? activities may risk privacy breaches, so the need for anonymizing such data before their release is increasingly recognized by organizations. Several approaches have been proposed recently to deal with this issue, but they are still inadequate...

In this paper we study a new restriction of the PAC learning framework, in which each label class is handled by an unsupervised learner that aims to fit an appropriate probability distribution to its own data. A hypothesis is derived by choosing, for any unlabeled instance, the label whose...

Based on multiple-case research, this paper develops a model of strategic information systems (IS) investment in small and medium-sized enterprises (SMEs). IS investment is modelled as a function of an SME's strategic context as defined by its strategic focus, i.e. cost reduction versus value...

The purpose of this thesis is to introduce a new broad approach to computing - Empirical Modelling (EM) - and to propose a way of applying this approach for system development so as to avoid the limitations of conventional approaches and integrate system development with business process...

For businesses planning interactions online, particularly using Web services, managing risks and accommodating each other's varying business-level security requirements is a complex but critical issue during development. Literature suggests numerous reasons that prohibit the simplistic adoption,...

This article examines the interdependency of population-level adaptation (evolution) and individual-level adaptation (learning). More specifically, we assume a trade-off between the two means of adaptation, that is, a higher individual-level adaptation can only be achieved with a reduced...

Liberalisation of telecommunications encourages competition between the various actors in the Open Service Market (OSM). In this highly competitive context, Connectivity Service Providers (CSPs) and Value Added Service Providers (VASPs) are investigating opportunities to provide differentiated...

This paper presents a model, which allows managers to identify the influence of their decisions to the potential innovation activity of the firm by simulation. Systems Thinking methodology has been used to understand the framework of innovation systems and to design and run the simulation model....

This paper is concerned with optimizing financial programs through the use of performance models to promote the best use of available computational resources, The work necessarily focuses on run-time optimization, where a performance model of the program is combined with knowledge of run-time...

This paper describes an approach to design self-developing and self-tuning inferential soft sensors applicable to process industries. The proposal is for a Takagi-Sugeno-fuzzy system framework that has evolving (open structure) architecture, and an on-line (possibly real-time) learning...
