Semantic Web and Semantic Web Services:
From Research and Technology to Deployed Applications  for Enterprises and Scientific Research


Amit Sheth, Semagix  and LSDIS Lab, The University of Georgia


Semantics can already be seen as the key enabler for the new breed of enterprise and scientific applications.  I have had the unique vantage point of seeing Semantic Web research transition from academic research at the LSDIS lab to commercialization at Taalee and Semagix, and further on to powering applications serving Enterprise customers and scientific research partners.  I see us in the earlier phase of a similar cycle for Semantic Services and Processes.


In this talk, we will review several ontology-driven applications and information systems.  For commercial applications, we will focus on Enterprise applications deployed by Semagix’s customers.  More specifically, these include risk management applications such as Anti-money Laundering and Case Management in Law Enforcement, and compliance application such as Security Clearance and Insider Threat Management.  For scientific research applications, we will primarily look at bioinformatics applications in Glycomics and Glycoproteomics.  For a Semantic Web platform that can support such applications, we will review the requirements, capabilities and state of the art technologies related to the following:

  • development of large populated ontologies that are regularly updated,
  • automatic metadata extraction from heterogeneous textual and media content as well as more high throughput scientific experiment data,
  • reasoning that computes semantic associations leading to identification or discovery of patterns or interesting/suspicious paths and complex relationships, and
  • semantic annotation of Web services and consequent development of Semantic Web Processes for more dynamic processes. 

We will also review our experiences in building practical ontologies that have involved hundreds of classes to a few million instances/assertions, and the approaches to deal with scalability and performance challenges in building real-world applications.

Speaker Biography


Amit Sheth is a professor of Computer Science at The University of Georgia (UGA) and the CTO of Semagix, Inc.  He started the LSDIS lab at UGA in 1994. For nine years before, he served in R&D groups at Bellcore, Unisys, and Honeywell.  In August 1999, Dr. Sheth founded Taalee, Inc., based on the SCORE technology developed at the LSDIS lab, and managed it as CEO until June 2001. Following acquisition/merger of Taalee and its follow-on Voquette resulting in Semagix, he currently serves as its CTO.  His research has led to two successful companies, three significant commercial products, several deployed applications, and over 200 publications. He has given 20 keynotes and over 150 invited talks/colloquia, has served on over 100 program committees, led organization of 15 international conferences/workshops and is the Editor in Chief of  International Journal on Semantic Web & Information Systems.  He received his BE from BITS (Pilani, India) and MS and PhD from OSU (Columbus, OH, USA).
