Began in 1979 as the Medical Computer Science (MCS) group of the Stanford Knowledge Systems Laboratory (KSL).  Work in the 1970s on computer systems such as MYCIN and other expert systems provided strong evidence that biomedical knowledge could be modeled computationally and processed to inform clinical decision making.  MCS was the unit in the School of Medicine where such work would be continued.

Product Overview


Protégé is a free, open source ontology editor and a knowledge management system. Protégé provides a graphic user interface to define ontologies. It also includes deductive classifiers to validate that models are consistent and to infer new information based on the analysis of an ontology.

This application is written in Java and heavily uses Swing to create the user interface.
