- 19. So why RDFover RDMS? Having a standard representation simply makes my life easier Lots of heterogeneous KUP data to be integrated RDF allows me to to simply pile more data in Natural support for ontologies Although limited RDF alone isn’t enough Next step, intelligent agents and crawlers… How do we harness all this connected data July 9, 2010Bio-ontologies, Boston
- 20. Challenges Bad modelling(?) – Conflation of instances and classes Cells bears some function (that is realised in some process) vs Cell participates in some Process False statements and vague semantics – Trying to accommodate the biologists queries – Mapping natural language to semantic relationships – Experiments, expression data, gene lists etc..

Editor's Notes
- #14 We initially chose a KUP portion of the FMA, but domain experts found that there was too much detail in some sections and not enough in others. In addition, too many ontological distinctions were made within the portion of the FMA and the consequent dispersal of information made it hard to use. In time, we could have refined the FMA to do the job required, but we found that the MAO had all the detail for our needs. Although the connecting tubule is absent in mouse and present in humans, the MAO has this entity. Therefore the MAO can act as a substitute for the human anatomy.
