Medical ontologies for computer assisted clinical decision support
DCFirst Claim
1. A method for use of a medical ontology for computer assisted clinical decision support, the method comprising:
- identifying, with a processor of a data mining system, a plurality of associated terms from a medical ontology;
generating, with the processor of the data mining system, a domain-knowledge base from the associated terms; and
mining, with the data mining system, a medical record as a function of the domain-knowledge base.

Abstract
Medical ontology information is used for mining and/or probabilistic modeling. A domain knowledge base may be automatically or semi-automatically created by a processor from a medical ontology. The domain knowledge base, such as a list of disease associated terms, is used to mine for corresponding information from a medical record. The relationship of different terms with respect to a disease may be used to train a probabilistic model. Probabilities of a disease or chance of indicating the disease are determined based on the terms from a medical ontology. This probabilistic reasoning is learned with a machine from ontology information and a training data set.
