A simple entry point to ontology resources ontocat.sf

OntoCat is an open-source Java-based tool designed to facilitate easy access and management of ontology resources. It provides a common interface for querying BioPortal, OLS, and local ontology files, overcoming challenges such as versioning, customization, and maintenance. With features like local caching, SKOS properties support, and additional annotations, OntoCat simplifies ontology applications development. It supports Java, REST, and JavaScript components to enable reuse and integration in various projects.

Presentation Transcript

  1. A simple entry point to ontology resources ontocat.sf.net

  2. To uniformly query OLS BioPortal OWL http://ontocat.sourceforge.net/

  3. Why ontologies are difficult to use? • Connecting to different public repositories • Custom ontologies and views • Versioning and identfier issues • Maintenance to keep up with changing application programming interfaces (BioPortal API)

  4. Motivation • Uniform interface to BioPortal, OLS, local files • Java, REST, JavaScript components • Reuse and integration for ontology applications

  5. Implementation • Java6 • Open source (LGPLv3) • Common OntologyService interface on top of BioPortal, OLS, and OWL API • Added value: • Easy access to additional annotations: symptoms, definitions • Local caching and ranking of ontology sources • Support for Simple Knowledge Organization System (SKOS) properties

  6. Applications • Updating external references in ontologies via BioPortal • Experimental Factor Ontology • Adding ontology terms to annotations in a database • Zooma

  7. Acknowledgments Tomasz Adamusiak K Joeri van derVelde NiranAbeygunawardena DespoinaAntonakaki Helen Parkinson Morris A. Swertz
