“…An ontology-based approach is preferred in order to avoid the inter-operability dilemma noted in [12]. This observed that the range of everyday objects supporting computing, sensing and actuating capabilities in pervasive computing presents a heterogeneity problem that will render impractical the solutions based on agreed interoperability standard common in communication and enterprise IT system today.…”

This requires accurate inference of user intent. Though individual user acts may be inferable from environmental context sensing, the inference of intent for which appropriate support might be offered is more challenging. Numerous researchers have used probabilistic techniques such as Bayesian Analysis techniques to attempt such inference. Unlike a desktop environment, however, pervasive computing environments are extremely heterogeneous, so any heuristics used must be tailored to the physical environment and the users in question. Thus these techniques are only likely to be accurate if configured with accurate knowledge of routine user behavior. Many existing approaches attempt to learn such knowledge from operational data, but this often requires user involvement in training and expert configuration of probabilistic processing structure. In this paper we examine a complimentary approach where users are presented with an intuitive interface to support the direct configuration of probabilistic structure by users with appropriate knowledge. By treating an intent inference system for a particular pervasive computng environment as an autonomic system, we approach the problem as the design of an intuitive governance interface for this system. We then present the design and usability evaluation of this governance interface.

“…On the other hand personalisation itself is developing rapidly. With the growing interest in context awareness and pervasive systems, personalisation functionality has evolved to take account of different aspects of the users' context, in an environment populated by many small, networked devices that can sense users' situation anytime, anyplace [7][8][9].…”

Abstract.A pervasive environment needs to take account of a user's context and preferences in determining which services to provide to the user. Moreover, one of the important features of a pervasive service environment is its dynamic nature, with the ability to adapt services as the context of a user changes, e.g. as he/she moves around. This paper describes how these requirement changes can be sufficiently accounted for by using a personalisation component to 'decide' what a user needs, and a composition component to continuously monitor services and the changes associated with them. The paper presents how services can be recomposed dynamically if the changes in context require it. This approach has been incorporated into a platform to support pervasive services. The service composition process used is described, and the way in which personalisation is incorporated into this process is shown. Finally the paper provides a brief account of two prototypes built as a proof of concept for these ideas.

The service-oriented architecture (SOA) is becoming increasingly popular as a paradigm for developing new distributed systems and integrating heterogeneous legacy systems. A service-oriented system (SO system for short) is a group of applications that interact with other(s) by providing and/or consuming services. As the deployments of serviceoriented applications and systems increase, it becomes obvious that systems management is the "Achilles' heel" of these systems. This paper reviews the underlying concepts, principles and technologies related to SO systems management.
