ProtégéRay: Advancing Ontology Development at Stanford Medical Informatics

ProtégéRay, part of the Stanford University School of Medicine, is a research initiative led by Mark Musen with a dedicated team of full-time staff and students. Our primary focus is on creating Protégé, an open-source Java tool for developing frame-based ontologies and knowledge bases, with over 6,000 registered users. We are funded by US Government grants and aim to enhance support for OWL through new developments, including a dedicated OWL backend. Our mission includes collaboration with the OWL community to improve editing environments and tackle current technical challenges.

  1. ProtégéRay Fergerson • Who are we? • What have we done? • What are our plans? • Why are we here? • What are our problems? • Demo (?)

  2. Who are we? • Stanford Medical Informatics – part of the Stanford University School of Medicine • Research project led by Mark Musen • Comprise about a half-dozen full-time staff (2 programmers + researchers) + students • Funded primarily by US Government grants and contracts (NCI, NLM) • http://protege.stanford.edu

  3. What have we done? (1) • Built an free, open-source, extensible Java tool for developing and maintaining frame-based (OKBC) ontologies and knowledge-bases. • Not built-in support for rules, inference, classification, etc. • Acquired 6000 registered users, 1000 active users.

  4. What have we* done? (2) • A number our users have developed plug-ins including interfaces to rule-based systems, classification engines, etc (JESS, Prolog, FACT) • Developed plug-ins for visualization, ontology management (merging, etc) and PSMs • Built plug-ins to interface to XML Schema and RDFS • Worked with SRI to develop a DAML+OIL plug-in (in alpha)*and our users

  5. What are our plans? • We are (will be) funded by NCI to develop an OWL backend for Protégé. • We have hired a postdoc who will be devoted to this effort. • Our near-to-intermediate term goal is to provide good support for OWL-Lite, with eventual support for full OWL.

  6. Why are we here? • Create new disasters. (Find out how we can best work with the core OWL community to develop the best editing environment for OWL that we can.) • Understand more about some of the technical problems in the spec • Understand the plans/timeline for the spec • Better understand the OWL species • Encourage development of reference parser

  7. What are our problems? • “differentFrom” • Need OWL full for: • Allowed-values • Metaclasses • Allowed-parents • Cardinality

  8. Demo (?)
