The paper proposes an intuitive configuration tool for autonomic pervasive computing systems. Specifically, the paper presents a system for the inference of user task intentions from a variety of sensed information and describes how this can be readily configured by users to meet their needs for performing particular activities in particular spaces. The approach taken combines the capture of user task concepts and policies with their integration into a 3D virtual reality model of the environment being used so that these concepts and policies can be mapped intuitively, but accurately, onto the sensed physical environment.

Almost all information domains have witnessed an exponential increase in the amount of structured data available. However, there is still a lack of support for ordinary users to create complex queries spanning multiple information sources. Until this occurs the real benefits of having such a proliferation of metadata will not be realized by the general public. This paper describes SARA (Semantic Attribute Reconciliation Architecture), which is a framework that helps users leverage expert knowledge to discover relevant information, and to draw correlations across separate information sources. These sources can be in various data formats, and are accessed by users in a consolidated fashion. Users are supported in their information exploration with the knowledge of experts, which they can further tailor to better suit their needs. SARA offers tools and support for domain experts with no computing experience to encode their expertise, thus opening up SARA's use to almost any domain where rich metadata is available. This paper discusses the SARA framework in detail, as well as describing the applications to which it has been successfully applied in a number of different domains.

The challenge of supporting Ubiquitous Computing is to assist the user by helping their applications make better decisions with better information. Smart spaces and other information sources can provide this information, but it is unrealistic to expect all the information to be represented in the same way everywhere. This means that the goal of ubiquitous computing translates into a problem of information integration. This paper presents a new knowledge-driven approach to applying contextual information to user applications. The objective of the design is to use a semantic integration, represented in topic maps, to deliver knowledge found in available services to personalise and improve the functionality of an integrated application. A brief discussion of the different semantic technologies employed in the system is followed by a presentation of the architecture of the system and its novel combination of semantic technologies. Two Use Cases are discussed, one specifically related to Ubiquitous Environments. Finally, the work is related to other research in the areas of Semantic Mediation and Context Awareness.

Managing networks and services in large virtual enterprises often requires significant expertise to decipher and reconcile information coming from several heterogeneous sources. This presents a significant challenge as the person with the network management expertise is not necessarily the person who has the task or vision of how to maximize the value of these services. Conversely it would be valuable for dedicated network managers to have insight into the meaning of the services running over the network. This paper presents an approach to empowering users to monitor and eventually manage network devices and services that they are not necessarily expert in. This paper details this challenge, presents two enabling technological frameworks and offers two compelling case studies currently being addressed in the Federated, Autonomic Management of End-to-End Communications Services (FAME) project.

The proliferation of smart home technologies providing home users with digital services presents an interoperability problem. This paper asserts that the value of these services can be greatly extended by enabling technology-neutral compositions of these home services, and furthermore that the reliability of such composite services will be of paramount importance to ensuring widespread deployment. Therefore fault management capabilities must accompany the composition capabilities in order to increase the robustness and reliability of such services. This paper proposes a web services-based abstraction layer for home area network service composition and a semantically informed fault management system for composed services, which can assist in diagnosis and correction of problems with composite services in smart homes of the future. Prototyping work and use cases are also described and initial metrics are presented that investigate the overhead of introducing the technology neutral abstraction layer.

As a result of the author's need for help in finding a given name for the unborn baby, the name ling, a search engine for given names, based on data from the ``Social Web'' was born. Within less than six months, more than 35,000 users accessed \name ling with more than 300,000 search requests, underpinning the relevance of the underlying research questions. The present work compares different metrics for calculating similarities among given names, based on co-occurrences within wikipedia. In particular, the task of finding relevant names for a given search query is considered as a ranking task and the performance of different statical measures of relatedness among given names are evaluated with respect to name ling's actual usage data. By publishing the considered usage data, the research community is stipulated for developing advanced recommendation systems and analyzing influencing factors for the choice of a given name.
