NCBO Web Services and the Development of Semantic Applications

Venue

• This tutorial will take place in association with the ICBO conference taking place in Graz, Austria. Registration details are provided here

Abstract

The National Center for Biomedical Ontology (NCBO) offers a range of Web services that allow users to access biomedical terminologies and ontologies, to use ontology terms to create pick lists and lexicons, to identify terms from controlled terminologies and ontologies that can describe and index the contents of online data sets (data annotation), and to recommend particular terminologies and ontologies that would be appropriate for data-annotation tasks. The BioPortal ontology repository provides a Web-based interface that utilizes the NCBO Web services and allows users to visualize ontologies, to map terms in ontologies to one another, and to add comments on ontologies that can guide ontology developers and offer assistance to ontology users.

Our Web services are used to create a searchable ontology-based index of data records, to create UIMA components for concept recognition, and to create structured data entry interfaces. This tutorial will provide hands-on experience using the NCBO Web services, and will offer participants in-depth understanding of how ontologies and terminologies are used to solve problems in biomedical informatics. The tutorial will demonstrate the use of Web services provided by NCBO to perform tasks such as semantic data integration, information retrieval, structured data entry, and knowledge management.
