OWL Class Expressions Learning in Python

64
/ 100
Established

Ontolearn helps knowledge engineers and ontology developers automatically discover new relationships and categories within their knowledge graphs. You provide examples of individuals that belong to a certain concept (positive examples) and individuals that don't (negative examples). The tool then generates complex OWL class expressions that define the concept, which can be used to enrich your ontology.

Available on PyPI.

Use this if you need to formally define complex concepts in an OWL ontology by providing examples, rather than manually writing the definitions from scratch.

Not ideal if you are not working with OWL ontologies or if your problem doesn't involve learning concept definitions from positive and negative examples.
