Semantic Web Expert Jeremy Carroll Teams with Protege OWL Creator Holger Knublauch to Propel Semantic Application Development Forward

ALEXANDRIA, Va., May 13, 2008 (BUSINESS WIRE) -- TopQuadrant(TM), a leading semantic technology products company,
today announced that Dr. Jeremy Carroll has joined TopQuadrant as
Chief Product Architect. Carroll has contributed to many Semantic Web
standards from the World Wide Web Consortium (W3C) and was the lead
architect in the creation of Jena 2.0, an open source Semantic Web
framework developed by Hewlett Packard Research Labs. Jena is
currently the most used Java toolkit for building semantic
applications and is the leading Java toolkit referenced in academic
papers and conferences.

At TopQuadrant, Carroll will work closely with Dr. Holger
Knublauch, TopQuadrant's Vice President of Product Development, to
extend the company's leading semantic application development
platform, TopBraid Suite(TM), and ensure that the integrated suite of
products continues to support W3C standards as they are developed.
Currently, TopBraid is the only W3C standards-based toolset that
supports the entire semantic application development lifecycle.

"Jeremy's unique skill set and vision for the future of semantic
application development will be a tremendous asset to TopQuadrant,"
said Irene Polikoff, TopQuadrant CEO and co-founder. "We believe that
the collaboration between Jeremy and Holger will help to push
enterprise-class semantic application development into the
mainstream."

"Semantic Web standards are now at a stage that, with the right
tool support, companies can use them to develop mission critical
applications," said Carroll. "I'm looking forward to working with
Holger and everyone at TopQuadrant. I believe that the combination of
Holger's skills in user interfaces and mine in semantic
infrastructure, will make a world-class team."

Carroll has been responsible for editing important W3C Semantic
Web standards: RDF Concepts and OWL Test Cases; and has made
significant contributions to many others including: GRDDL, GRDDL
Tests, OWL Semantics, RDF Semantics, RDF Syntax and the Quality
Assurance Framework.

Prior to joining TopQuadrant, Carroll spent sixteen years as a
senior research scientist at Hewlett Packard, where he conducted
research in the areas of knowledge engineering, Semantic Web
technology, telecommunications, very large databases, distributed
printing and Venn triangles. While at HP Labs, Carroll architected the
Jena 2.0 Semantic Web framework and led the development of the first
alpha version of the code.

Before HP Labs, Carroll was a researcher at the University of
Manchester Institute of Science and Technology (UMIST), where he
studied computational linguistics and machine translation,
specializing in Japanese and Turkish.

Carroll holds a Ph.D and a M.Sc. from the University of Manchester
Institute of Science and Technology, both in computational
linguistics, and a prize-winning BA in Mathematics from Oxford
University.
