  1. Rubber Hits the Road:Why NEMO needs RDF PaeaLePendu Stanford Center for Biomedical Informatics Research National Center for Biomedical Ontology (NCBO) Stanford University February 26, 2010 NEMO All-hands Meeting. Atlanta, GA. Feb. 26-8, 2010.

  2. Information Processing(Where I Come In) NEMO All-hands Meeting. Atlanta, GA. Feb. 26-8, 2010.

  3. Ontology • Formal knowledge representation • Logic + XML = OWL • Structure & Relationships • Unique names for unique terms (URIs) • Overlap (Mappings) • Linked via the Web • Tools • Protégé • BioPortal • Pellet Reasoner NEMO All-hands Meeting. Atlanta, GA. Feb. 26-8, 2010.

  4. NCBO BioPortal NEMO All-hands Meeting. Atlanta, GA. Feb. 26-8, 2010.

  5. RDF – Resource Description FrameworkWho is Eric Miller?(http://en.wikipedia.org/wiki/Resource_Description_Framework) NEMO All-hands Meeting. Atlanta, GA. Feb. 26-8, 2010.

  6. NEMO Annotation Task Force(http://nemo.nic.uoregon.edu/wiki/Data_Annotation) • Key Personnel: • Haishan Liu, Bob Frank, Jason Sydes • Gwen Frishkoff & Dejing Dou • Goals (3 phases): • Prototyping Annotations • Finessing Annotations (term selection) • Databasing the Annotations (RDF) NEMO All-hands Meeting. Atlanta, GA. Feb. 26-8, 2010.

  7. Simulated ERP Summary Metrics • Data- format, labels, meaning? NEMO All-hands Meeting. Atlanta, GA. Feb. 26-8, 2010.

  9. Annotation at NCBO(http://www.bioontology.org/resources-index) • Resource Index • PubMed, PubChem, ClinicalTrials, Gene Expression Omnibus, DrugBank, etc. • Data is a publication or article • Resource is a supplier of data • Index associates data to ontology terms • 20 resources (going on 100) • Over 5 BILLION annotations! NEMO All-hands Meeting. Atlanta, GA. Feb. 26-8, 2010.

  10. Annotation at NEMO • Tagged Datasets • Search & Retrieval • Mining datasets: • Co-occurrences • Cross-correlations • Frequent items • Tag clouds • Minimal inference P100 Visual Auditory N100 NEMO All-hands Meeting. Atlanta, GA. Feb. 26-8, 2010.

  11. Deep Annotation at NEMO • Tagged records within datasets • Rich semantics • Detailed queries (SPARQL) • Aggregations • Mining data instances • Fine-grained analysis • NEMO is novel! NEMO All-hands Meeting. Atlanta, GA. Feb. 26-8, 2010.

  12. Linked Open Data(http://linkeddata.org/) NIF BioPortal NEMO NEMO All-hands Meeting. Atlanta, GA. Feb. 26-8, 2010.
