23. A system for use of a medical ontology for computer assisted clinical decision support, the system comprising: a memory operable to store a probabilistic model having machine learned probabilities for relationships from a medical ontology, the machine learned probabilities for the relationships learned from the medical ontology automatically with no manual input or semi-automatically with user tuning; and a processor operable to apply the probabilistic model.
26. The system of claim 23 wherein the processor is operable to mine unstructured data of a medical record as a function of a knowledge base derived from the medical ontology, and wherein the processor is operable to apply the probabilistic model to results of the mining.
