Multi-perspective modelling MPM techniques allow the presentation and analysis of complex organisational knowledge from different points of view, thus al-lowing the knowledge to be used for different purposes. This paper describes the multi-perspective modelling approach that has been adopted as a part of the Air Operation Enterprise Modelling (AOEM) project[7]. Three models have been developed: a Busi-ness Model to describe the concepts and processes that are used in the context of air op-erations, a Role Activity and Communication Model to identify actors involved and the operations and interactions between them, and a Meta-Model to provide a taxonomic structure to capture all concepts that are important to the air operation. To assist the Multi-Perspective modelling efforts, a framework has been proposed which uses Meta-Model as a light-weight ontology to provide communication of domain knowledge between models. An underlying formal method provides the basis for the automation of...

Abstract. The CoAKTinG project aims to advance the state of the art in collaborative mediated spaces for the Semantic Grid. This paper presents an overview of the hypertext and knowledge based tools which have been deployed to augment existing collaborative environments, and the ontology which is used to exchange structure, promote enhanced process tracking, and aid navigation of resources before, after, and while a collaboration occurs. While the primary focus of the project has been supporting e-science, this paper also explores the similarities and application of CoAKTinG technologies as part of a human centred design approach to e-Learning. 1

The use of mobile devices is becoming increasingly more frequent. Although very limited, these devices now have capacities for running more advanced systems. Opportunities for developing applications using artificial intelligence have emerged with the release of APIs that are not aimed at proprietary platforms, such as J2ME. This paper discusses some approaches of artificial intelligence planning aimed at mobile computing and subsequently presents an approach to delivering intelligent planning information to users of mobile devices that are participating in collaborative planning environments. Access to planning information by human agents on the move can improve several aspects of planning processes, including collaboration.

This paper introduces an intelligent simulation tool that aims to improve our understanding of the dynamics of supply chain operation. The proposed added value of this tool lies in the explanation of simulation results, the support of knowledge propagation across the supply chain and the capture of supply chain communication, all of which are facilitated by using Artificial Intelligence techniques. The conceptualisation framework for modelling a supply chain, and the tool’s scope and behaviour are discussed.

htmlabstractLong-term monitoring of the underwater environment is still labour intensive work. Using underwater surveillance cameras to monitor this environment has the potential advantage to make the task become less labour intensive. Also, the obtained data can be stored making the research reproducible. In this work, a system to analyse long-term underwater camera footage (more than 3 years of 12 hours a day underwater camera footage from 10 cameras) is described. This system uses video processing software to detect and recognise fish species. This footage is processed on supercomputers, which allow marine biologists to request automatic processing on these videos and afterwards analyse the results using a web-interface that allows them to display counts of fish species in the camera footage.

Enterprise model development is essentially a labour- intensive exercise. Human experts depend heavily on prior experience when they are building new models making it a natural domain to apply Case Based Reasoning techniques. Through the provision of model building knowledge, automatic testing and design guidance can be provided by rule-based facilities. Exploring these opportunities requires us not only to determine which forms of knowledge are generic and therefore re-usable, but also how this knowledge can be used to provide useful model building support. This paper presents our experiences in identifying and classifying the knowledge which exists in IBM's BSDM Business Models and applying AI techniques, CBR and Rule-Based reasoning together with a symbolic simulator, to provide more complete support throughout the enterprise model development life cycle. 3

The CoAKTinG (Collaborative Advanced Knowledge Technologies in the Grid) project has developed a set of integrated tools to enhance collaboration between e-Scientists. As one of three case studies, these tools are being applied within the Combechem e-Science pilot project. Two levels of integration are being explored: straightforward deployment of generic CoAKTinG tools, and a “deep” integration between these tools and the Combechem grid. The deeper integration supports the publication at source research objective of Combechem, in which a digital record is maintained through the information processing chain that starts in the laboratory, supporting retrospective use in the e-Science process. In this paper we provide an overview of the tools and we focus in particular on the adaptation of one of the tools for the Combechem application.

Video data collected continuously are pervasive today but analyzing them in an efficient manner has proven to be a challenge. This is because raw data is unlabelled and prone to noise, causing difficulty in extracting knowledge. With the aid of userprovided domain knowledge and heuristics used by image processing experts, an automated solution is implemented. It makes use of formalisms for goaldirected behavior in the form of hierarchical task networks (HTNs). These are incorporated within a novel workflow composition framework that aims to assist naive users conduct complex video processing tasks automatically. An example is illustrated for video classification, fish detection and fish counting in unconstrained underwater videos.

This paper describes our efforts to provide a collaborative problem solving architecture driven by semantic-based worko w orchestration and con- straint problem solving. These technologies are based on shared ontologies that allows two systems of very different natures to communicate, perform specialised tasks and achieve common goals. We give an account of our approach for the worko w assisted collaboration

Overview The need for more sophisticated web-based sup-port tools has become apparent with the evolve-ment of the World Wide Web and the Seman-tic Web vision 1 . For organisations with business goals, the automation of business processes as web services is increasingly important, especially with many business transactions taking place within the web today. With the existence of Business Pro-cess Modelling (BPM) methods and Workflow tech-nologies, web services can benefit from these ma-ture approaches to allow for the manipulation and execution of processes. Some effort have been made to overcome this pitfall [Chen-Burger, Stader 2003],[Guo et al 2004],[BPEL4WS 2005], yet there still exists a gap that needs to be addressed be-tween enterprise modelling methods and web ser-vices. In this proposal we seek to find means to bridge the gap that exists between BPM methods and web services by attempting to map a seman-tic based process modelling language, Fundamental Business Process Modell...

1 Motivation: The motivation for this project is to find out whether social behaviour patterns can be extracted using a semi-formal modelling method called a knowledge map [3][4], which describes the relationships between several actors and their activities. The actors collaborate to form a community and also have informal connections by using the same resources or publishing papers together. Knowledge management is a relatively young field and has thus far been focused mostly on managing explicit knowledge in knowledge bases and information systems. The next step anticipated in the evolution of knowledge management is focusing more on the people aspect and thus capturing the implicit knowledge in organisations or communities. Social network analysis (SNA) can be used to analyse social networks, thereby inferring information about the status of each member of the community and his strength and weaknesses. SNA can be applied to achieve a variety of goals such as smoothing information...

Explosion of information and increasing demands on semantic processing Web applications have pushed software systems to their limits. To address this problem, we propose a semantic-based formal framework (ADP) that makes use of promising technologies to enable knowledge generation and retrieval. We argue that this approach is cost- effective, as it reuses and builds on existing knowledge and structure. It is also a good starting point for creating an Organizational Memory and providing Knowledge Management functions.

An I-Room is an "intelligent room" which can act as a knowledge aid to support collaborative meetings and activities, especially when these involve making sense of the current situation, planning, considering options, and making decisions. The I-Room provides a generic technology platform for a wide range of potential collaborative applications and uses. It provides a conduit for accessing intelligent systems and knowledge bases from collaborative interaction spaces such as virtual worlds. Described in this paper are applications of the I-Room to support a geographically dispersed cross-disciplinary team in a creative industry (the development of a multi-media video game); to support virtual operations centres for emergency response and public safety; and to support a mixed-initiative tutored social/promotional activity (an expert-led whisky-tasting).

This dissertation describes a project which was carried out as part of an M.Sc. course in Knowledge-Based Systems at the Department of Artificial Intelligence of the University of Edinburgh. A knowledge-based support tool for business modeling with IBM's Business System Development Method (BSDM) was built. The tool, KBST, is designed for use during and between BSDM workshops, where business and IT personnel of companies are developing business models. In this dissertation, a brief overview of BSDM is given and it is shown that the application development package HARDY, a hypertext diagramming tool produced by the Artificial Intelligence Applications Institute, provides a good platform for a BSDM support tool. It is also shown how case-based reasoning techniques can successfully be applied to implement a model analysis mechanism for BSDM. Acknowledgments Firstly, I would like to thank my supervisors, David Robertson and John Fraser, for their valuable help and guidance during the...

ABSTRACT Enterprise Modeling (EM) methods are recognised for their value in providing a more organised way to describe a complex, informal domain. A problem with EM is that it does not always provide direct input for software system development. There is a "gap" between EM and software systems. One solution to bridge this gap is to provide a formalisation, here called "FWFL", for all models using a business process langauge, Fundamental Business Pro-cess Modeling Language (FBPML), which is a merger of IDEF3 and PSL. FWFL is used to provide a declarative de-scription of a workflow system and is tested in the "PC-configuration" domain. We also suggest using a validation and verification support framework to analyse and verify the business process model (BPM). Finally, some complex-ity results are presented for this type of modeling.
