Completing the Total Wellbeing Puzzle Using a Multi-agent System 283<br />
Organization-based multi-agent systems are designed for to be used within a<br />
specific institution. Usually, these systems help manage <strong>and</strong> use the existing information.<br />
For example, Agent Cities [3] is a multi-agent system that consists of<br />
agents that provide <strong>medical</strong> services. The agents enable the user to access his/her<br />
<strong>medical</strong> record, to make a booking to be visited by a particular kind of doctor <strong>and</strong><br />
to search for <strong>medical</strong> centres on the basis of a given set of requirements. AADCare<br />
[4] agent-based system is designed as a decision support system for physicians. It<br />
has the ability to map patient’s records to the predefined domain knowledge such as<br />
disease knowledge, clinical management plans, patient records etc.<br />
Other multi-agent systems retrieve information from the Internet. <strong>Bio</strong>Agent [5]<br />
is a mobile agent system where each agent is associated with a given task. For<br />
successful completion of its task, the agent needs to travel among multiple locations.<br />
At each location, the agent performs a set of actions. Information integration<br />
procedure takes place at the end of the trip. Holonic Medical Diagnostic System<br />
(HMDS) [6] architecture is a <strong>medical</strong> diagnostic system i.e. Internet-based diagnostic<br />
system for diseases. It is based on the holonic paradigm, multi-agent system<br />
technology <strong>and</strong> swarm intelligence. The patient’s information is kept in comprehensive<br />
computer readable patient record called computer readable patient pattern<br />
(CRPP). The agents of the holarchy use the information available via Internet to<br />
processed CRPP. Another work describes web crawling agents [7] that can be designed<br />
to fetch information about diseases on the basis of the information about<br />
mutated genes related to these diseases.<br />
Use of the ontologies within bio<strong>medical</strong> communities is of great significance<br />
[8]. The Gene Ontology (GO) (http://www.geneontology.org/) has been used to<br />
annotate major repositories for plant, animal <strong>and</strong> microbial genomes. This has<br />
resulted in consistent descriptions of gene products in different databases. The<br />
Unified Medical Language System (UMLS) [8] contains 1 million bio<strong>medical</strong><br />
concepts, 135 semantic types <strong>and</strong> 54 relationships used to classify the UMLS concepts.<br />
Human Disease Ontology [10] captures <strong>and</strong> represents knowledge about<br />
human diseases according the four different dimension: disease types, symptoms,<br />
causes <strong>and</strong> treatments subontologies. Protein Ontology (http://proteinontology.<br />
info/) [11] enables capturing of declarative knowledge about protein domain <strong>and</strong><br />
classification of that knowledge to allow reasoning. It enables access not only to<br />
related data but also semi-structured data such as XML or metadata annotations <strong>and</strong><br />
unstructured information. A large number of bio<strong>medical</strong> ontologies is available via<br />
The Open <strong>Bio</strong><strong>medical</strong> <strong>Ontologies</strong> (http://obofoundry.org/). These ontologies cover<br />
various knowledge domains such as anatomy, biological processes, biochemistry,<br />
health <strong>and</strong> taxonomy.<br />
In our project we focus on making a channel through which dispersed health information<br />
will be unified under one umbrella to help identify interdependencies<br />
<strong>and</strong> interrelationship between different aspects of health. Lots of the information is<br />
available but, due to the large body of information, some important information<br />
may escape the users notice <strong>and</strong> be neglected.<br />
The Web crawling agent <strong>and</strong> <strong>Bio</strong>Agent system could be used by our system<br />
with some modifications. We can use the same principle of fetching information,<br />
agent migration among multiple locations, information retrieval from each location<br />
<strong>and</strong> information integration at the end of the trip. But the information we are
