The Semantic Web Semantics for Data and Services on the Web

A decade ago Tim Berners-Lee proposed an extraordinary vision: despite the p- nomenal success of the Web, it would not, and could not, reach its full potential unless it became a place where automated processes could participate as well as people. This meant the publication of documents and data to the web in such a way that they could be interpreted, integrated, aggregated and queried to reveal new connections and answer questions, rather than just browsed and searched. Many scoffed at this idea, interpreting the early emphasis on language design and reas- ing as AI in new clothes. This missed the point. The Grand Challenge of the Semantic Web is one that needs not only the information structure of ontologies, metadata, and data, but also the computational infrastructure of Web Services, P2P and Grid distributed computing and workflows. Consequently, it is a truly who- system and multi-disciplinary effort. This is also an initiative that has to be put into practice. That means a pragmatic approach to standards, tools, mechanisms and methodologies, and real, challenging examples. It would seem self-evident that the Semantic Web should be able to make a major contribution to clinical information discovery. Scientific commu- ties are ideal incubators: knowledge-driven, fragmented, diverse, a range of str- tured and unstructured resources with many disconnected suppliers and consumers of knowledge. Moreover, the clinicians and biosciences have embraced the notions of annotation and classification using ontologies for centuries, and have dema- ing requirements for trust, security, fidelity and expressivity.

Vipul Kashyap, PhD is a Senior Medical Informatician in the Clinical Informatics Research & Development group at Partners HealthCare System. He plays the role of a systems and information architect in the content of a platform for Clinical Knowledge Management Platform and creating of clinical information models in the context of the Enterprise Clinical Services architecture at Partners Healthcare System. Vipul has received his PhD from the Department of Computer Science at Rutgers University in New Brunswick that investigated the use of metadata and ontologies for information and knowledge management. He was a co-project manager of a Knowledge Management effort at Telcordia Technologies (formerly known as Bellcore) focused on knowledge sharing and reuse across Telcordia's Professional Services Units. He was a fellow at the National Library of Medicine, and has held positions at Micro-electronics and Computer Technology Corporation (MCC) and the National Institute of Standards and Technology (NIST). Vipul has published 2 books on the topic of Semantics in Information Brokering and Integration, 40-50 articles in prestigious conferences and journals. He serves on the editorial boards of 3 journals and sits on the technical advisory board of an early stage companies developing semantics-based products. He also represents Partners on the W3C Advisory Committee and the EHR Technical Committee of the HealthCare Information Technology Standards Panel (HITSP).
