Identifying Communities of Practice: Analysing Ontologies as Networks to Support Community Recognition - O'Hara, Dr Kieron; Alani, Dr Harith; Shadbolt, Prof Nigel
Communities of practice are seen as increasingly important for creating, sharing and applying organisational knowledge. Yet their informal nature makes them difficult to identify and manage. In this paper we set out ONTOCOPI, a system that applies network analysis techniques to an ontology to target the problem of identifying such communities.

notes of 13th Nov 2001 - Walker, Michael
The following is at its core a discussion and attempt to circumscribe the problem of knowledge management, and is followed by an attempt to understand how technology can be made to address this end.

Managing Knowledge Capture: Economic, Technological and Methodological Considerations - O'Hara, Dr Kieron; Shadbolt, Prof Nigel
This paper examines the process of managing knowledge capture from within an organization, i.e. the process of making tacit knowledge explicit. Any knowledge management decision to capture tacit knowledge needs to be informed by the costs incurred and benefits produced. These costs and benefits vary radically depending on properties of the domain, the organization, the knowledge to be captured and the importance of excluding others from the benefits of the knowledge. The picture is further complicated by the difficulties involved in valuing knowledge. We survey these factors, and seek to integrate such considerations into standard knowledge management methodologies (using CommonKADS...

Informal Semantics for the FBPML Data Language - Chen-Burger, Dr. Yun-Heh
FBPML is a merging and adaptation of two recognised process modelling languages (PML): PSL [7] and IDEF3 [8]. PSL provides formal semantics for commonly shared process modelling concepts as well as theories such as situation calculus that support the use of such concepts. As it is designed to be an interchange language between different process languages, it covers the core concepts in PML, but does not provide visual notations or model development methods.
IDEF3 is originated from manufacturing environment and is one of the richest methods available in the process modelling community. It provides visual notations and a rich modelling...

On the integration of technologies for capturing and navigating knowledge with ontology-driven services - Kalfoglou, Yannis; Domingue, John; Carr, Leslie; Motta, Enrico; Vargas-Vera, Maria; Buckingham Shum, Simon
Nowadays, many distinct communities are researching for knowledge capturing, modelling, and navigation. Moreover, advances in Internet technology makes it possible to perform most of these task on heterogeneous and distributed environments such as the Web. These advances though, have raised the need for knowledge services to accommodate the ever increasing number of Web users. To provide such a service one needs to combine key technologies for different aspects of knowledge management: capturing, modelling, navigating. This should be tightly integrated with the intented service. We describe such an integration effort in this paper. Our domain is a Web-based news repository and...

ONTOCOPI: Methods and Tools for Identifying Communities of Practice - Alani, Dr Harith; O'Hara, Dr Kieron; Shadbolt, Prof Nigel
The paper describes ONTOCOPI, a tool for identifying communities of practice (COPs) by analysing ontologies of the relevant working domain. COP identification is currently a resource-heavy process largely based on interviews. ONTOCOPI attempts to uncover informal COP relations by spotting patterns in the formal relations represented in ontologies, traversing the ontology from instance to instance via selected relations. Experiments to determine particular COPs from an academic ontology are described, showing how the alteration of threshold settings, temporal settings, and the weights applied to the ontologys relations affect the composition of the identified COP.

Linking with Meaning: Ontological Hypertext for Scholars - Kampa, Dr Simon; Miles-Board, Mr Timothy; Carr, Dr Leslie; Hall, Prof Wendy
The links in ontological hypermedia are defined according
to the relationships between real-world objects. An
ontology that models the significant objects in a scholars
world can be used toward producing a consistently
interlinked research literature. Currently the papers that are available online are mainly divided between subject- and publisher-specific archives, with little or no
interoperability. This paper addresses the issue of
ontological interlinking, presenting two experimental
systems whose hypertext links embody ontologies based on
the activities of researchers and scholars.

Knowledge Based Multi-Perspective Framework For Enterprise Modelling - Chen-Burger, Dr. Yun-Heh
Multi-perspective modelling MPM techniques allow the presentation and analysis of complex organisational knowledge from different points of view, thus allowing 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. Three models have been developed: a Business Model to describe the concepts and processes that are used in the context of air operations, a Role Activity and Communication Model to identify actors involved and the operations and interactions between them, and a Domain-Model to provide a taxonomic structure to capture...

A Framework for Reference Management in the Semantic
Web - Lewy, Timothy; Glaser, Hugh; Shadbolt, Prof Nigel
Much of the semantic web relies upon open and unhindered interoperability between diverse systems. The successful convergence of multiple ontologies and referencing schemes is key. This is hampered by a lack of any means for managing and communicating co-references. We have therefore developed an ontology and framework for the exploration and resolution of potential co-references, in the semantic web at large, that allow the user to a) discover and record uniquely identifying attributes b) interface candidates with and create pipelines of other systems for reference management c) record identified duplicates in a usable and retrievable manner, and d) provide a...

Report on Summer Internship Work For the AKT Project: Benchmarking RDF Triplestores - Streatfield, Michael; Glaser, Hugh
This report details the work done on the benchmarking of RDF triplestores over the summer. It talks about the structure of the tests performed and the scripts produced which were used to run the tests. It is intended to be useful in both assessing the results produced and for anyone who wishes to take the work on further in the future. This work was done in conjunction with Dr Jeremy Frey and Kieron Taylor of the University of Southampton's Chemistry department. I have gone into as much detail as possible whilst trying to keep it relevant, so that the scripts...

Semantic Learning Narratives - Pasin, Michele; Motta, Enrico
In this paper we highlight the importance of an interpreta-tion of the learning process from a narrative perspective and show how Semantic Web technologies, in particular ontologies, can serve to represent the key dimensions of this approach and to support an intelligent navigation of learning resources. Here we introduce our initial work in order to formalize the structure of these learning narra-tives in the domain of philosophy.

Using the Semantic Web to Navigate Conceptual Spaces: an Application for the Philosophical Domain - Pasin, Michele; Motta, Enrico
The semantic web offers new possibilities in the eLearning area, which are dependent at least on two factors: the increasing availability of resources on the web and the semantic power of their meta-descriptions. This paper looks at this second issue, and tries to determine the general framework and the important features of the metadata for a specific domain, philosophy. Thanks to an adequate conceptualization, in fact, it is possible to recollect resources and compose them into a novel narrative, in order to provide specific learning services.

Enabling Active Ontology Change Management within Semantic Web-based Applications - Liang, Mr. Yaozhong
Enabling traceable ontology changes is becoming a critical issue for ontology-based applications. Updating an ontology that is in use may result in inconsistencies between the ontology and the knowledge base, dependent ontologies and applications/services. Current research concentrates on the creation of ontologies and how to manage ontology changes in terms of mapping ontology versions and keeping consistent with the instances. Very little work investigated on-the-fly keeping track of ontology changes while update (active ontology versioning) and using these information to control the impact on dependent applications/services, which is the aim of our research presented in this thesis. The approach we...

Facilitated Hypertext for Collective Sensemaking: 15 Years on from gIBIS - Conklin, Dr Jeff; Selvin, Dr Albert; Buckingham Shum, Dr Simon; Sierhuis, Dr Maarten
Hypertext research in the mid-1980s on representing argumentation for design rationale (DR) foreshadowed what are now dominant concerns in knowledge management: representing, codifying and manipulating semiformal concepts, the use of formalisms to mediate collective sensemaking, and the construction of group memory. With the benefit of 15 years' hindsight, we can see the failure of so many DR systems to be adopted as symptomatic of the more general problem of fostering new kinds of 'literacy' in real working environments. Pursuing Engelbart's goal of "augmenting human intellect", we describe the Compendium approach to collective sensemaking, which demonstrates the impact that a facilitator...

Concept Mapping Between Compendium and IX - Chen-Burger, Dr. Yun-Heh; Tate, Prof. Austin
This document provides a conceptual framework for mapping modelling primitives between I-X adn Compendium. It extends the initial description of issues discussed during the CoAKTinG workshop at Open University, October 10-11, 2002. Its content is based on a follow-up internal Edinburgh meeting and the design of new I-X v3.0. Feedback in telephone conversations with Michelle Bachler from OU has also been factored in.
