The range of publicly available biomedical data is enormous and is expanding fast. This expansion means that researchers now face a hurdle to extracting the data they need from the large numbers of data that are available. Biomedical researchers have turned to ontologies and terminologies to structure and annotate their data with ontology concepts for better search and retrieval.

Using the annotation workflow of the [[Annotator_Web_service]] NCBO has built an biomedical resources index in which biomedical data is indexed by ontology concepts. The index allows a user to search for biomedical data based on ontology concepts. The NCBO Resource Index is directly queriable in the [[http://bioportal.bioontology.org BioPortal]] ontology repository: when a user browses a given concept, he has access (link) to the list of resource elements that have been annotated with this concept. A user can also search for resources direclty using the 'All resources' tab.

In the OBR index, we have processed the textual metadata of elements from five biomedical resources: [www.ebi.ac.uk/arrayexpress/ Array Express], [http://clinicaltrials.gov/ Clinical Trials.gov], [http://goldminer.arrs.org GoldMiner], [www.ncbi.nlm.nih.gov/geo/ Gene Expression Omnibus (GEO)] and others. The annotations in the index keeps track of the structures of elements that have been annotated i.e., from which part of the element (e.g., title, description) an annotation has been produced. This information is used to score annotations.
