Clark & Parsia.

Consulting, Research & Design, Infrastructure

Clark & Parsia, LLC, is a small consulting and R&D firm—specializing in Semantic Web and advanced systems—based in Washington, DC, with government and commercial clients.

What We Know

We offer commercial support for Pellet, a best-of-breed Open Source OWL DL reasoner in Java. We're also experts in a range of advanced technologies: all aspects of Semantic Web and Semantic Web Services, including OWL, description and other logics, RDF, reasoning at scale, ontology development, policy management and analysis, machine learning and data mining, etc.

What We Do

We're building up a portfolio of infrastructure technologies in the semantic space, including:

• Pellet, the best-of-breed OWL DL reasoner
• Owlgres, a scalable OWL reasoner for large, database-like applications
• Pronto, a probabilistic reasoner for OWL applications
• OwlSight, a Web 2.0, in-browser ontology browser/editor app
• XACML-DL, an OWL-based XACML policy analysis tool
• JSpace, a Linked Data Browser in Java

We're focused on building semantic infrastructural pieces that empower other technology companies to make the move to semantic technology. We're pursuing OEM and related business models that allow us to license our technology for use by our customers who are building vertical apps.

But these technologies are only interesting if they help our customers solve hard problems. What our customers care about are solutions to their technical challenges—we're equipped to help them with

• information integration solutions across disparate data sources, including databases, web services, etc;
• policy management and analysis services, including access control, web service, and other policy languages;
• solving complex configuration problems for complex systems, including logistics, configuration certifications;
• realistic assessments of the utility of semantic technologies; and
• cutting-edge application development when off-the-shelf solutions just won't work.

We specialize in thinking clearly to solve hard problems—that's the kind of work we're doing today and the kind we'll do in the future.

If you face substantial technical challenges in these or related areas, drop us a line and we'll talk about how we can help you overcome them.
