• Part I: GoPubMed• Part II: practical
Life science literature
• 600.000 researches work in the life sciences
• PubMed literature database contains 17.000.000 scientific abstracts
• Annual growth ca. 500.000
agenda
life science literature
• most important source for researchers
• a lot of unstructured information • growth rapidly• common vocabulary helps searching

PubMed
• Great resource if one knows what one is looking for–“Kox1” has 17 hits
• But “diabetes” will produce >279.394
How can the common vocabulary of the GeneOntology be used to facilate literature search?

Examples
PMID 7578980: ”Primed monocytes transcribed TNF mRNA at a higher rate than freshly isolated monocytes upon activation with LPS.”
(for monocyte activation (GO:0042117))
PMID 7612661: ”Although all nm23 proteins contain nucleoside diphosphate (NDP) kinase activity, it has not been established that the enzyme activity mediated the various functions of nm23 proteins.”
(for protein kinase activity (GO:0004672)).

Concept recognition
• difficult as terms are not used in their lexical base form
• Inter-annotator agreement between 65 to 85%
• Good entity recognition systems: ~90% f-value
• Generel concepts may be mis-interpreted („development“ has 8 meanings in WordNet)
• Machine learning can achieve very good results for disambiguation but you need training data
