  6. BIOSEMANTICS • “Cellese”: the language that cells use to communicate internally and externally. • The Molecular Language and its biological MEANING • The Group • Jan Kors PhD. • Erik van Mulligen PhD • Bob Schijvenaars PhD • Marc Weeber PhD • Christiaan v.d. Eyck MsC • Rob Jelier PhD • Barend Mons PhD • Johan van der Lei PhD

  7. A consortium to combine State-of-the-art • Information and Knowledge Mining Technologies • To support: • Thesaurus and ontology enrichment • Disambiguation of concepts • Semantic meta-analysis of massive information • To enable: • Information-based discovery • Evidence based policy making

  8. Thesaurus and Ontology Enrichment • New concepts • Synonyms • Homonyms • Genes, Proteins • Pictures

  9. Elsevier EMBO E-BioSci partners Fingerprints (known concepts) 4 1 FUA • Thesauri: • Mesh • HUGO • SwissProt • SAGE • Others NLP 2 TNO UVA Genebio EUR HUGONC AMC LUMC SERENDIP Free text Unexplained Text (XML) Validation 3 Potential concepts

  10. Too much to read: major trends foreseen: • From Reading to Consulting • From Reading to Meta-analysis • From Text to Knowledge Representations

  13. META-ANALYSIS Fingerprinting disambiguation ACS

  14. Applications • Cross-language, jargon and cross-system matching (implemented): www.sharingpoint.shared-global.org • Information-based discovery (Research) • Community building (Experts,Policy Making) • Trendwatching and Indicators (Policy Making)

  15. BRCA1 Seed-Term based Conceptual Semantic Networks

  16. gene B gene A Clustering of genes on-the-fly ?

  17. Predicting new knowledge ?

  18. III= Distribution over distance categories of concept-pairs without co-occurrence in the learning set. IV= Distance categories of concept pairs related to the probability that there is no explicit relationship or co-occurrence in Medline (zero ratio) . A ratio of 0 means that an automatic Query in Medline with the concept pair with “AND” in between does lead to 0 hits in Medline.

  19. New Drug discovery ?

  20. Semantic Filtering

  21. Knowledge Maps, Nature Biotechnology Map
