Abstract. This paper briefly describes the work we have undertaken in the MIAKT project to provide a generic architecture and user interface for distributed multimedia knowledge management with the...
Multimedia Distributed Knowledge Management in MIAKT (2009)
An Dasmahapatra, Bo Hu, Paul Lewis, Nigel Shadbolt
Abstract. Digital media facilitates tight integration of multi-modal information and networking allows this richly textured knowledge to be shared. We present the system we have developed in the...
Incorporating Probabilistic Knowledge in HealthAgents: a Conceptual Graph Approach (2009)
Madalina Croitoru, An Dasmahapatra, Paul Lewis
Abstract HealthAgents is a multi-agent, distributed decision support system for brain tumor diagnosis. Knowledge needs to be shared amongst different agents in order to assist clinicians when making...

Abstract. The diversity and distributed nature of the resources available in the semantic web poses signicant challenges when these are used to help automatically build an ontology. One persistent...
Cooperative Information Sharing to Improve Distributed Learning (2005)
Partha Dutta Srinandan, Partha S. Dutta, An Dasmahapatra, Steve R. Gunn, Nicholas R. Jennings, Luc Moreau
Effective coordination in partially observable MAS requires agent actions to be based on reliable estimates of nonlocal states. One way of generating such estimates is to allow the agents to share...
Managing Patient Record Instances Using DL-Enabled Formal Concept Analysis (2004)
Bo Hu, An Dasmahapatra, Paul Lewis, Nigel Shadbolt
Abstract In this paper we describe a general logic-enabled Formal Concept Analysis (FCA) approach to manage patient record instances. In particular, the conceptual model of the domain is represented...
MIAKT: Combining Grid and Web Services for Collaborative Medical Decision Making (2004)
