Definition

The Ontology Lookup Service (OLS, http://www.ebi.ac.uk/ols) provides interactive and programmatic interfaces to query, browse, and navigate over 80 ontologies and controlled vocabularies covering wide selection of domain-specific knowledge. The OLS is currently heavily used by several databases and data-entry tools, and new ontologies are always being incorporated as domain experts make them available.

Characteristics

One of the challenges of systems biology is the need to integrate large amounts of potentially disparate information, coming from multiple sources, being generated by different techniques and instrumentation. Proper annotation provides a Rosetta stone through which the systems biologist can start making sense of all of this information by providing a stable and consistent context to make this vast corpus of data comparable.

The Ontology Lookup Service was created to provide a simple, centralized, integrated interface to query multiple domain-specific ontologies...

Acknowledgments

OLS contributors have been supported through the Biotechnology and Biological Sciences Research Council (BBSRC) ISPIDER grant, the EU FP6 “Felics” (contract number 021902 (RII3)) grant, and the EU FP7 “Sling” grant (grant number 226073). We would like to thank all users who have contributed recommendations and requests. Many improvements, already executed and some ongoing, come directly from this feedback.
