2007 Computer-Based Medical Systems (CBMS), Proceedings of the IEEE Symposium on  
We present HADOM (HealthAgents Domain Ontology) which conceptualises the required HealthAgents information and propose describing the sources knowledge by the means of Conceptual Graphs (CGs) .  ...  This paper focuses on the problem of representing, in a meaningful way, the knowledge involved in the HealthAgents project.  ...  Acknowledgements This work is supported under the OpenKnowledge and HealthAgents STREP projects funded by EU Framework 6 under Grant numbers IST-FP6-027253 and IST-FP6-027213.  ...

Incorporating Probabilistic Knowledge in HealthAgents: a Conceptual Graph Approach

Madalina Croitoru, Srinandan Dasmahapatra, Paul H. Lewis
2008 International Conference on Conceptual Structures  
This paper presents a way of encoding and utilising such statistical information. The Simple Conceptual Graphs that describe a given hospital cases will be used to retrieve related information.  ...  Querying expressivity requirements as well as the need for visual capabilities further led to the development of a Conceptual Graph based description of the data sources: knowledge oriented specification  ...  We propose a Conceptual Graph based methodology for retrieving relevant information that might help the clinician in the process of classifier selection.  ...

A knowledgeable security model for distributed health information systems

Liang Xiao, Bo Hu, Madalina Croitoru, Paul Lewis, Srinandan Dasmahapatra
2010 Computers & security  
We examine the capability of the Lightweight Coordination Calculus (LCC), a process calculus based language, in meeting security challenges in pervasive settings, especially in the healthcare domain.  ...  In this paper, we reflect upon our experiences in the HealthAgents project wherein a prototype system was developed and a novel approach employed that supports data transfer and decision making in human  ...  Knowledge-intensive case-based reasoning in creek.

The HealthAgents ontology: knowledge representation in a distributed decision support system for brain tumours

Bo Hu, Madalina Croitoru, Roman Roset, David Dupplaw, Miguel Lurgi, Srinandan Dasmahapatra, Paul Lewis, Juan Martínez-Miranda, Carlos Sáez
2011 Knowledge engineering review (Print)  
Our initial motivation came from the distributed nature of the information involved in the system and has been enriched by clinicians' requirements and data access restrictions.  ...  We motivate our representational choices and show our results using domain examples employed by clinical partners in HealthAgents.  ...  The European Community is not liable for any use that may be made of the information contained herein.  ...

A Conceptual Graph Description of Medical Data for Brain Tumour Classification [chapter]

Madalina Croitoru, Bo Hu, Srinandan Dashmapatra, Paul Lewis, David Dupplaw, Liang Xiao
Lecture Notes in Computer Science  
This paper shows how Conceptual Graphs can be employed to describe the data sources in the HealthAgents system.  ...  HealthAgents proposes an agent-based distributed decision support system for brain tumour diagnosis and prognosis which employs Magnetic Resonance Imaging and Magnetic Resonance Spectroscopy techniques  ...  We are also investigating a Conceptual Graph based case base reasoning approach for HealthAgents.  ...

Towards agent-oriented model-driven architecture

Liang Xiao, Des Greer
2007 European Journal of Information Systems  
Business representations, however, cannot be fully and explicitly represented in such models for direct transformation into running systems.  ...  This provides a means of model-based adaptation rather than code-based adaptation.  ...  The business objects of 'fault' and 'asset' established previously are retrieved and encoded in messages.  ...

A review of attacks and security approaches in open multi-agent systems

Shahriar Bijani, David Robertson
2012 Artificial Intelligence Review  
Focusing on information leakage in choreography systems using LCC, we then suggest two frameworks to detect insecure information flows: conceptual modeling of interaction models and languagebased information  ...  A limitation of both conceptual modeling and language-based frameworks is difficulty of formalising realistic policies using annotations. iv Finally, the proposed security-typed LCC is applied to a cloud  ...  In(Sit and Morris 2002) a similar attack called store and retrieve is introduced in peer to peer systems.  ...
