Whether and how medical personnel and their digital systems can talk to one another in a meaningful way is a subject pertinent to the health of patients about whom they "converse." An internationally recognized ontologist points out, however, that these electronic systems frequently do not employ the same ontology -- or system of meaning -- which results in harmful, and even fatal, consequences for patients. This problem will be addressed at the International Conference on Biomedical Ontology (ICBO), hosted by UB.
