Title: IST2103 STP Artemis: A Semantic Web Servicebased P2P Infrastructure for the Interoperability of Medi
1IST-2103 STP Artemis A Semantic Web
Service-based P2P Infrastructure for the
Interoperability of Medical Information systems

- Ankara, Turkey
2Challenges - why we do this project?
- According to Jonathan Borden, M.D. of ASTM
- A disaster 1.1 Trillion /year in the USA
- 30-40 overhead
- Mostly paper based
- Highly proprietary commercial systems
- Tens of thousands of people die each year due to
poor information/errors - Most of the information is rendered useless
3Challenges - why we do this project?
- The systems must interoperate for effectiveness
- For interoperability standards are needed
- However there are more than one standard in the
health care domain HL7, CEN TC 251, GEHR,
4Challenges - why we do this project?
- Most of the health information systems today are
proprietary - They often only serve one specific department
within a healthcare institute - To complicate the matters worse, a patient's
health information may be spread out over a
number of different institutes which do not
interoperate - This makes it very difficult for clinicians to
capture a complete clinical history of a patient
5Objectives Interoperability through
Semantically Enriched Web services in the
Healthcare Domain
- Achieving interoperability among Medical
Informations systems through - Web service technology, and
- Semantic Web
- Furthermore to increase the discovery feature for
Web services, Web services will be integrated
with the Peer-to-peer networks
6We will give semantics to WebServices through
exiting healthcare standards

10Web Services in the Healthcare Domain
- Web services provides the healthcare industry
with an ideal platform to achieve the difficult
interoperability problems - Web services are designed to wrap and expose
existing resources and provide interoperability
among diverse applications - By introducing Web services to the healthcare
domain, it becomes possible to provide the
interoperability of medical information systems
through standardizing the access to data through
WSDL and SOAP rather than standardizing
documentation of electronic health records
11Impact of Web services in theHealthcare Domain
- Introducing Web services to the healthcare domain
brings many advantages - It becomes possible to provide the
interoperability of medical information systems
through standardizing the access to data through
WSDL and SOAP rather than standardizing
documentation of electronic health records - Medical information systems suffer from
proliferation of standards to represent the same
data - Web services allow for seamless integration of
disparate applications representing different
and, at times, competing standards - Web services will extend the healthcare
enterprises by making their own services
available to others - Web services will extend the life of the existing
software by exposing previously proprietary
functions as Web services
12Impact of Semantics in theHealthcare Domain
- By exploiting semantically enriched Web services,
it becomes possible - To provide the interoperability of Healthcare
standards at the semantic level - Discovery, monitoring and composition of Web
services are facilitated
13Impact of Semantics and P2Pnetworks in the
Healthcare Domain
- Facilitates discovery and sharing of resources
- Provides for scalability
14End result of the ArtemisProject
- A middleware providing the interoperability of
Medical Information Systems - The project intends to produce
- Tools for facilitating the creation of Web
services from existing applications, databases
and Web pages - Message and functionality ontologies for
healthcare Web services - Tools for semantically annotating healthcare Web
services - Web service composition tool based on BPEL4WS
- Web service registries (UDDI and ebXML) enriched
with healthcare semantics - Integrating Web services and Web services
registries with P2P networks - Semantic routing on the P2P networks for
discovery of healthcare related information
15Market
- Artemis project will be one of the first
initiatives to use Web services in the healthcare
domain - We plan to produce an early prototype to
demonstrate system capabilities to the widest
possible audience - The market size will depend upon the system
capabilities and how wide we can disseminate the
results
16Technological Limits
- Web services No limit Already a
well-established technology supported by major
software vendors (Microsofts .NET, IBM
WebSphere, BEAs WebLogic) - Semantic Web Limiting factor The healthcare
ontologies are not there yet - What is available
- Message exchange specifications, e.g., HL7
- Controlled vocabularies, e.g., ICD-10
(International Statistical Classification of
Diseases and Related Health Problems) - Taxonomies, e.g., SNOMED-CT
17Risks
- Security We must make sure to provide the
necessary security measures with healthcare Web
services - User friendliness We must develop easy-to-use
interfaces - Performance We must make sure that the
performance of the system is acceptable to the
industry
