Protégé is an editor for modeling ontologies in computer science .
The ontology editor was designed at the Institute for Medical Informatics at Stanford University in California and is now freely available as an open source application under the Mozilla Public License . Protégé was originally developed to create knowledge databases or ontologies for medical research purposes. These ontologies in the IT sense are formal, machine-readable representations of knowledge in a specific subject area (so-called domain ), which is mapped by so-called concepts and relations .
With Protégé , such knowledge databases can be created, filled with information and knowledge from it queried. The development and runtime environment is programmed in Java and is therefore platform-independent .
Knowledge modeling with formal description languages is possible in Protégé in two ways:
- Protégé-frames works with the frame-based approach of knowledge representation , which provides information about specific domain knowledge in a hierarchical structure of concepts, attributes of concepts ( slots ) and concept instances (individuals).
- Protégé-OWL is based on the Web Ontology Language (OWL), the standard for ontology creation within the Semantic Web . In contrast to the frame-based approach, there are additional logical mechanisms through which implicit knowledge from the modeled data structure - also across multiple ontologies - can be inferred.
Protégé has a good 300,000 registered users (as of May 2016).
