Testimonials for OWL2 Recommendation

These testimonials are in support of the W3C Press Release "W3C Standard Facilitates Information Management and Integration".

Clark & Parsia LLC

Clark & Parsia LLC is pleased to welcome OWL 2, the new revision of the Web Ontology Language. Our customers -- ranging from federal government to Fortune 500 enterprises and cutting-edge startups -- see OWL 2 as a significant step toward industrial-class ontology-based computing systems. In particular, OWL 2's support for profiles and increased expressivity will accelerate real-world adoption in information integration, decision support, and related domains. Our product line, including Pellet and PelletDb, supports OWL 2 extensively and will continue to lead innovation in the area of OWL and related semantic web technologies.

IBM is pleased to recognize the technical achievement in the publication of the new Web Ontology Language (OWL 2.0). IBM has been very active in the development of semantic technologies and their applications to provide tangible and lasting business value to our customers. We have developed innovative approaches to scale OWL reasoning to large and expressive knowledge bases. We have applied Semantic Technologies, including OWL, to address a variety of real-world problems in various domains: from matching patients to available clinical trials, to detecting frauds in financial markets; from enhancing search over medical literature to developing a state-of –the-art tool for collaborative investigation, reasoning, and analysis.

Kaiser Permanente

Kaiser Permanente has over 8 million members and is the largest nonprofit health care delivery system in the United States. Our medical record system is entirely electronic, with diagnoses and procedures mapped to SNOMED-CT. We are able to find cohorts of patients for research, decision support, and quality reporting using the reasoning capabilities of SNOMED-CT. Primarily because of our extensive needs for subsumptive queries, we especially applaud the efforts of the W3C in creating the EL profile for OWL which allows us to work with medical terminology in an OWL compliant way.

Karlsruhe Institute of Technology (KIT)

We welcome the new revision of the Web Ontology Language (OWL 2) reaching W3C recommendation status. As a backwards-compatible extension of OWL with new capabilities, OWL 2 will continue to play a major role for knowledge-driven web applications and services developed within our institution. The new light-weight profiles, improved datatype support, and key-based data integration of OWL 2 provide a long-wanted possibility of leveraging scalable inferencing mechanisms for the Web of Data. Various OWL-2-enabled tools, including the NeOn Toolkit and the HERAKLES reasoning broker, are developed or re-used in our ongoing projects.

Mayo Clinic

Mayo Clinic pioneered the concept of the group practice of medicine before the turn of the century in Rochester, Minnesota, and has grown to become the nation's largest such practice. The modern era of patient record oriented research began at Mayo in 1907 with the introduction of the Unit Medical Record, which collated all patient information into a single dossier. Today, Mayo operates a federated suite of electronic medical record systems that extensively use CHI (Consolidated Health Informatics) health vocabulary standards and coding systems. Mayo welcomes the OWL 2 recommendation as an important step along the path towards a new generation of tools that will enable individualized medicine, and promote secondary uses of data for clinical research and improving quality of care.

Oracle congratulates the W3C on achieving Recommendation status for OWL 2. As an active participant in this working group, Oracle believes customers and vendors can benefit from the latest advances for the Semantic Web through important new modeling capabilities in OWL 2 including property chains and keys. Oracle is a strong supporter of OWL (OWL 1) and has delivered multiple releases of Oracle Database that include native inference capabilities, enabling customers to model their domain using a standard vocabulary and semantics, which eases and speeds up the modeling process. We look forward to helping OWL 2 progress as a W3C Recommendation.

Sandpiper Software

Sandpiper Software is pleased to support the OWL 2 Recommendation. Our tools and services for UML-based information modeling rely heavily on the OWL 1 standard, which we are currently migrating to OWL 2. A number of the new features clarify or extend aspects of the language that are critical for solving complex classification problems in science and engineering. The profiles provide much more flexibility in addressing performance issues in large scale deployments. We are delighted to help move the changes forward into related specifications at the Object Management Group over the coming months.

Siemens Healthcare

On behalf of Siemens Healthcare, I would like to express our endorsement for OWL2 as a W3C recommendation.

The development of OWL2 is central to Siemens Healthcare's development of next generation clinical systems and integrated enterprise wide knowledge management. The extensions in OWL 2 are essential, including qualified cardinality restrictions (min/max), property chains, and richer annotations including annotation of individual axioms ( e.g. for maintaining the order of statements in OWL files). The work we are doing is critically dependent on these features. We also strongly support the greater clarity for different OWL Profiles , allowing greater flexibility in reasoner support.

We believe that OWL2 has the potential to support better patient care and the adoption of Personalized Medicine, by permitting the formalization of knowledge ontologies that it can support. We are actively building clinical solutions based upon OWL, and many of the requisites that we have encountered will be addressed with OWL2. I strongly urge its adoption.

— Sam Brandt, Chief Medical Informatics Officer, Siemens Healthcare

University of Manchester

We have used preliminary versions of the OWL2 language in educational, research and commercial applications for the past two years. It addresses key issues: a) The fine grained axiom annotations allow detailed tracking of provenance in collaborative development and testing; b) The use of qualified cardinality restrictions allows simpler and more semantically complete representation of key constructs; c) The availability of concrete data types, including numeric ranges, allows support of applications in scientific disciplines that depend on quantitative measures; d) Property paths support solutions to problems in equivalence of expressions that have plagued health informatics for a generation.

— Alan Rector, Professor of Medical Informatics, University of Manchester

University of Oxford

The University of Oxford warmly welcomes the OWL 2 Recommendation. Our Computing Laboratory is one of the world's leading centres for Semantic Web research, and we are heavily involved in the development of semantic technologies, such as our HermiT OWL reasoner, and their deployment in application areas as diverse as healthcare, travel and the humanities. The increased clarity and precision of the OWL 2 specification, the extended capabilities of the language, and the flexibility offered by the profiles, will be of great benefit in both these endeavours, and we have already made sure that HermiT is fully OWL 2 compliant.

About the World Wide Web Consortium (W3C)

The W3C was created to lead the Web to its full potential by developing common protocols that promote its evolution and ensure its interoperability. It is an international industry consortium jointly run by the MIT Computer Science and Artificial Intelligence Laboratory (MIT CSAIL) in the USA, the European Research Consortium for Informatics and Mathematics (ERCIM) headquartered in France and Keio University in Japan. Services provided by the Consortium include: a repository of information about the World Wide Web for developers and users, and various prototype and sample applications to demonstrate use of new technology. To date, nearly 400 organizations are Members of the Consortium. For more information see http://www.w3.org/
