OBTAINING SUPPORTED DECISION TREES FROM TEXT FOR MEDICAL HEALTH APPLICATIONS

Abstract:

Systems, devices, and methods discussed herein provide improved decision trees (e.g., supported decision trees). A supported decision tree can be generated by generating discourse trees from various documents associated with a subject. One or more decision chains can be generated from each discourse tree, each decision chain being a sequence of elements comprising a premise and a decision connected by rhetorical relationships. A supported decision tree can be generated from the various decision chains, where the nodes of the decision tree are identified from the elements of the plurality of decision chains and ordered based on a set of predefined priority rules. Subsequent input data can be received and the supported decision tree can be traversed to classify the input data.
