Specialized Mechanisms for Term Inference

Abstract

A method for generating rules for rule-based inference, comprising the steps of: starting from a set of general inference rules defined in an ontology by using in at least one of said general inference rules having more than one variable The class(s) replaces at least one of the variables to generate a set of specific inference rules.

Description

technical field [0001] The invention relates to a rule-based reasoning method. Background technique [0002] Clinical decision support is the technology used to assist physicians in decision-making tasks such as obtaining a diagnosis of a patient. [0003] Clinical decision support systems typically perform queries against large data repositories of patient data. Clinical terms are used in such queries to express domains of interest. Successful retrieval of desired results depends heavily on understanding the terminology used and its hierarchy. [0004] Term reasoning is therefore required when performing such queries. Executing queries against data repositories by reasoning techniques based on state-of-the-art rules can take a significant amount of computational effort, which may be unacceptable. [0005] Accordingly, one aspect of the invention provides a technique that results in a reduction in the computational effort required to solve a query by transforming the set...
