Education

Sheth received his Bachelors in Engineering from the prestigious Birla Institute of Technology and Science in Computer Science in the year 1981.He received his MS and Ph.D in Computer Science from the Ohio State University in 1983 and 1985 respectively.

Research

emantic Interoperability/Integration and Semantic Web

Sheth has investigated, demonstrated, and advocated comprehensive use of metadata. He explored syntactical, structural, and semantic metadata; recently, he has pioneered ontology-driven approaches to metadata extraction and semantic analytics. He was among the first researchers to utilize description logics based ontologies for schema and information integration (a decade before W3C adopted a DL-based ontology representation standard). His work on multi-ontology query processing includes the most cited paper on the topic (over 485 citations). In 1996, he introduced the powerful concept of Metadata Reference Link (MREF) for associating metadata to hypertext that links documents on the Web, and described an RDF-based realization in 1998, long before RDF was adopted as a W3C recommendation. A part of his recent work has focussed on information extraction from text to generate semantic metadata in the form of RDF. In his work, semantic metadata extracted from biological text is made up of complex knowledge structures (complex entities and relationships) that reflect complex interactions in biomedical knowledgeciteweb

Workflow Management and Semantic Web Services

In the early 1990s, he initiated research in the formal modeling, scheduling, and correctness of workflows. His METEOR project demonstrated the value of research with real-world applications; its tools were used in graduate courses in several countries, and its technology was licensed to create a commercial product.

The follow-on METEOR-S project has been highly influential. He led the research (later joined by IBM) that resulted in the W3C submission of WSDL-S (Semantic Annotation of WSDL), the basis for SAWSDL, a W3C recommendation for adding semantics to WSDL and XML Schema.

He currently guides the development of SA-REST, which supports microformat-based annotation of popular RESTful services and WebAPIs. For both SAWSDL and SA-REST, he has provided leadership in the community-based process followed by W3C. He coauthored a 1995 paper in the journal of Distributed & Parallel Databases (Springer),which is one of the most cited papers in the area of workflow management literature, with more than 1200 citations, as well as the most cited among over 430 papers published in that journal.citeweb

Information Integration

• Federated and multidatabase architectures for integration and interoperability of heterogeneous databases, organized along the dimensions of distribution, heterogeneity, and autonomy
• Schema and view integration, with new and practical integration techniques and tools including the first tool on schema integration (1987) developed in the United States
• Quality and integrity of data in multiple databases, defining the concept of polytransaction and multidatabase consistency specification with innovative ticketing method for multidatabase concurrency control.
