1 Andreas Doms Biotechnology Center Technical UniversityDresden ontology-based literature search life science literature gopubmed hands-on curation tool examples agenda

2 Andreas Doms Biotechnology Center Technical UniversityDresden ontology-based literature search life science literature gopubmed hands-on curation tool agenda examples Part I: GoPubMed Part II: practical

3 Life science literature researches work in the life sciences PubMed literature database contains scientific abstracts Annual growth ca agenda life science literature most important source for researchers a lot of unstructured information growth rapidly common vocabulary helps searching ontology-based literature search gopubmed hands-on curation tool examples

4 PubMed Great resource if one knows what one is looking for –“Kox1” has 17 hits But “diabetes” will produce > How can the common vocabulary of the GeneOntology be used to facilate literature search? agenda life science literature most important source for researchers a lot of unstructured information growth rapidly common vocabulary helps searching ontology-based literature search gopubmed hands-on curation tool examples

5 The Gene Ontology agenda life science literature ontology-based literature search Gene Ontology long result lists concept regonition the idea of ontology- based search gopubmed hands-on curation tool examples

6 Searching in PubMed agenda life science literature ontology-based literature search Gene Ontology long result lists concept regonition the idea of ontology- based search gopubmed hands-on curation tool examples

7 Searching in PubMed agenda life science literature ontology-based literature search Gene Ontology long result lists concept regonition the idea of ontology- based search gopubmed hands-on curation tool examples

8 Identification of ontology terms… Concept recognition agenda life science literature ontology-based literature search Gene Ontology long result lists concept regonition the idea of ontology- based search gopubmed hands-on curation tool examples

9 We all know sequence alignment agenda life science literature ontology-based literature search Gene Ontology long result lists concept regonition the idea of ontology- based search gopubmed hands-on curation tool examples

10 Idea: Use it for concept identification agenda life science literature ontology-based literature search Gene Ontology long result lists concept regonition the idea of ontology- based search gopubmed hands-on curation tool examples

11 Examples PMID : ”Primed monocytes transcribed TNF mRNA at a higher rate than freshly isolated monocytes upon activation with LPS.” (for monocyte activation (GO: )) PMID : ”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: )). agenda life science literature ontology-based literature search Gene Ontology long result lists concept regonition the idea of ontology- based search gopubmed hands-on curation tool examples

12 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 agenda life science literature ontology-based literature search Gene Ontology long result lists concept regonition the idea of ontology- based search gopubmed hands-on curation tool examples

13 thioredoxin-disulfide reductase activity (GO: ) small-molecule carrier or transporter (GO: ) Endonuclease activity, active with either ribo- or deoxyribonucleic acids and producing 5’-phosphomonoesters (GO: ) [methionine synthase] reductase activity (GO: ) structural constituent of chorion (sensu Insecta) (GO: ) Concept recognition agenda life science literature ontology-based literature search Gene Ontology long result lists concept regonition the idea of ontology- based search gopubmed hands-on curation tool examples
