This project is concerned with the process of managing intrusiveness in pervasive computing environments. In particular, we intend to investigate the use of argumentation-based negotiation as mechanism for managing intrusivess in a context sensitive fashion.
The Centre for Digital Library Research, established in 1998, co-ordinates the group's digital library activities and the development of electronic archives of historical manuscript collections. Collaborative activities in this area include work on the Wellington, Mountbatten, Churchill and Turing archives in collaboration with the archivists at the University Library and the University of Cambridge.
The project is working on creating a digital version of the Alan Turing archive held at Kings College Cambridge. It has digitised around 800 items as a trial and made them available as http://www.turingarchive.org/, using various technologies from the IAM group.
Simulation is being extensively used by the armed forces to train their troops as an alternative to carrying out expensive exercises in the field. The objective of using a computer for training is to provide the soldiers with the experience of working part of a team in various battle situations in conditions as much like those in the real world as possible. The simulation should provide a realistic training ground for the soldiers where it is possible to test the soldiers' skills in a variety of situations.
This project investigates the issues involved when you use the multi-agent system paradigm to model the battlefield scenario. Agents are used to represent a variety of different entities in the organisational heirarchy of the army, who must work together as a team in order to achieve the battle objectives. It is important to look at the structures and protocols that need to be in place for the effective and efficient accomplishment of the overall task. This will be based on the joint intentions model of Jennings [jennings 93] and the STEAM execution model of Tambe [tambe 98]. We are particularly interested in how the agents deal with uncertainty and failure and what mechanisms need to be used to ensure that the task is still accomplished despite the breakdown of one or several parts of the team plan.

This EPSRC funded collaborative project aims to apply game theoretic techniques to the design of negotiation algorithms for use by autonomous software agents in electronic commerce. The other partner is the ESRC Centre for Economic Learning and Social Evolution (ELSE).
A JISC eLib project to provide a framework for publishing journals in a network environment for maximising access to the the publications. This involved adding hypertext navigation overlays (using the Distributed Link Service and information mining agents) to static archives of prepublished material. We are currently seeking outlets for the resulting hypertext technologies.
The OpCit project is developing a reference linking service for Open Archives using the Distributed Link Service and adapting tools for reference linking from PDF documents that were developed in the earlier Open Journal Project ().
Initially the project will hyperlink each of more than 100,000 papers in the Los Alamos physics eprint archive to every other paper in the archive that it cites. The project will extend to link references in papers held in other freely-accessible, distributed archives that conform with the proposal for Open Archives.
Working with the Cornell Digital Library Research Group the project will also investigate the semantics of documents to allow linking, and model interoperability between linking services and other digital library services.
It is hoped that this new way of navigating the scientific journal literature will encourage authors in other fields to create inter-linked online archives like Los Alamos, or Cogprints, across disciplines and around the world. A related project, EPrints, provides free software to enable institutions or special interest groups to build these new online archives.
The OntoPortal system uses ontological hypermedia principles to enrich the linking between resources (or concepts) within a scholarly community (such as the literature, projects and conferences), allowing researchers to not only position a concept within the context of the entire community in which they work, but more importantly, allows them to pose intricate research queries (such as What other papers discuss the XML standard?).
The links in ontological hypermedia are defined according to the relationships between real-world objects. An ontology that models the significant objects in a scholar's world can be used towards producing a consistently interlinked research portal. After formally defining the concepts and complex relations within a particular community, the OntoPortal system is used to project the relationships between the concepts over the information contained within the scholarly community. This greatly improves the navigational facilities offered by the system by adding rich and meaningful interlinking of the concepts.
While the underlying resources might only contain a few links, all concepts within the OntoPortal system are linked to every other related concept (as defined by the ontology). The resulting ontological hypermedia allows users to not only fully understand how the concepts relate to the rest of the community, but introduces the ability to respond to queries by following links (query-by-linking) as opposed to issuing a search query. For example, resolving the query, What other papers discuss the XML standard? simply involves following the link between the literature and the standard as this relationship has been made explicit through the ontological hypermedia.
Initially we applied the OntoPortal system to the metadata research community under a project funded by the Defence Evaluation and Research Agency (DERA). We used the OntoPortal system to provide a rich interlinking between the concepts in the metadata research community.
