This page lists use cases and provides examples of how these questions can be answered using NCBO software (web services and widgets), and includes links to code samples and documentation.

I have a list of terms that were used to annotate a data set, how can I see if any of these terms exist in standard ontologies?

• Use the Search Web service to search for your term in all ontologies in BioPortal. If you have a small list of terms, searching each term individually via the BioPortal Search UI may be sufficient. Otherwise, for a long list of terms, use the Search Web service directly.
  • Search Web service documentation: http://www.bioontology.org/wiki/index.php/NCBO_REST_services#Search_services
  • Example code: https://bmir-gforge.stanford.edu/gf/project/client_examples/scmsvn/?action=browse&path=%2Ftrunk%2F

I would like to find all terms mapped from my ontology to other ontologies in BioPortal

• Use the Mapping web service to find terms in other BioPortal ontologies similar to terms in your ontology. These mappings include mapping generated manually (DbXrefs) and programatically (LOOM).
  • Mapping Web service documentation: http://www.bioontology.org/wiki/index.php/NCBO_REST_services#Mapping_Service
  • Example code: https://bmir-gforge.stanford.edu/gf/project/client_examples/scmsvn/?action=browse&path=%2Ftrunk%2FPerl%2FExtractMappings%2F

I am the curator for a database and need to triage papers to identify which papers from PubMed are most related to my database and a good source of new information to add to my database

• Use the Annotator Web service to identify ontology terms in textual data.
  • Annotator Web service documentation: http://www.bioontology.org/wiki/index.php/Annotator_Web_service
  • Example code: https://bmir-gforge.stanford.edu/gf/project/client_examples/scmsvn/?action=browse&path=%2Ftrunk%2FJava%2FAnnotator%2F (Java), https://bmir-gforge.stanford.edu/gf/project/client_examples/scmsvn/?action=browse&path=%2Ftrunk%2FPython%2FAnnotator%2F (Python)

I have PubMed abstracts and want to link information in the abstracts to my database of interest.

• Use the Annotator Web service. If your database of interest is included in the NCBO Resource Index you can search the database(s) for records that contain these terms. See http://www.bioontology.org/wiki/index.php/Resource_Index for more details on the Resource Index web service.

I have a web form with text fields I would like to populate with ontology terms, e.g. to select relevant Gene Ontology terms.

• Use the Autocomplete widget (example for the Gene Ontology, http://bioportal.bioontology.org/ontologies/44532#widgets). Select the "Get Code" button for the code and instructions on how to add this Javascript to your web form. If you would like to limit the terms to a subset of the Gene Ontology, create this subset and then load this ontology subset as a View of the Gene Ontology (http://bioportal.bioontology.org/ontologies/44532#views).

I would like to add the graph display of my ontology on my web site.

• Use the Visualization widget for your ontology of interest from the widgets page (example for Gene Ontology, http://bioportal.bioontology.org/ontologies/44532#widgets). Select the "Get Code" button for the code and instructions on how to add this Javascript to your web form.

I would like to get all terms from an ontology and re-format the data to use in my own system.

• Use the Get All Terms Web service to get all terms and properties for your ontology of interest.
  • Get All Terms Web service documentation: http://www.bioontology.org/wiki/index.php/NCBO_REST_services#Get_all_terms_using_the_specific_ontology_version_id and http://www.bioontology.org/wiki/index.php/NCBO_REST_services#Get_all_terms_using_the_virtual_ontology_id) to get a list of all of the terms and all details about each term, e.g. synonyms, definition, subclass, etc.

I need to navigate through an ontology and traverse the ontology hierarchy for my software application, how can I use the Web services to do this?

• Use the Get All terms Web service.
  • Example coming soon...

How can I limit the selection of ontologies used with the NCBO Annotator to a certain Category or Domain?

• Use the List all ontologies and Get Groups/Domains Web service to identify the group/domain of interest.
  • Example coming soon...
