Abstract:

Services are pervasive in today's economic landscape, and services-based
architectures are rapidly being adopted for enterprises as well as for
Web applications. The need for a broad perspective on services that
takes in people and organizational descriptions in addition to
technical interface descriptions has already been recognized as part of
the overall vision of services science. To this mix, we  add the
middleware (including distributed and cloud computing) that improves the
implementation and interoperability of service oriented architecture (SOA).

In this context, we present the semantic services science (3S) modeling
framework to support service descriptions that capture system/technical,
human, organizational, and business value/requirements aspects. We
believe that a combination of Web2.0 and semantic technology can be used
to energize services across the broad service spectrum. We describe how
the 3S approach could be used along four points in this spectrum: (1)
semantic descriptions of standard Web services (with the help of SAWSDL
and semantic policy descriptions);  (2) semantic descriptions of
lightweight Web services (with the help of semantic annotation of REST
services and WebAPIs---SAREST) and semantic or smart mashups (smashups)
using Web 2.0 technologies (e.g., REST, AJAX) and microformats;  (3)
semantics at the middleware (communication, configuration, and
adaptation); and  (4) ontology-based profiling of people and
organizational aspects of the assets associated with business and
knowledge services, as well as semantic analysis of business
requirements.  Such processes would be critical to the agile businesses
and innovative Web applications that are part of our global and
networked economy.

Biography of Speaker:

Amit Sheth is an educator, researcher, and entrepreneur. He is the
LexisNexis Ohio Eminent Scholar for Advanced Data Management and
Analysis at Wright State University, where he directs the Kno.e.sis
center <http://knoesis.wright.edu/> for Knowledge enabled Information &
Services Science (http://knoesis.org).  Earlier, he was a professor at
the University of Georgia, where he founded and directed the LSDIS lab,
widely recognized as a leading international research group in the areas
of semantic Web, SOA and workflows. Before that, he served in R&D groups
at Bellcore, Unisys, and Honeywell. His research has led to several
commercial products and two successful companies in the areas of
Workflow Management and Semantic Web, which he founded and managed in
various executive roles. Professor Sheth is an IEEE Fellow and has
received recognitions such as the IBM Faculty award. He has published
over 250 papers and articles many of which are highly cited (current
h-index = 54, 24 with over 100 citations each), given over 200 invited
talks and colloquia including 30 keynotes, (co)-organized/chaired 45
conferences/workshops, and served on around 120 program committees. He
is on several journal editorial boards, is the Editor-in-Chief (EIC) of
the /International Journal on Semantic Web and Information Systems
(IJSWIS <http://ijswis.org/>)/, joint EIC of Distributed & Parallel
Databases Journal, and co-editor of two Springer Book Series.
