Method, apparatus and computer program product for constructing a diagnostic network model
First Claim
1. A method for constructing a diagnostic network model comprising:
- automatically reviewing a structured electronic representation of a document, wherein automatically reviewing comprises automatically identifying at least one symptom, a plurality of components and causal relationships between a failure of the respective components and the occurrence of at least one symptom;
associating respective probabilities with the causal relationships between the at least one symptom and the plurality of components; and
automatically constructing the network model of the at least one symptom, the plurality of components, the causal relationships therebetween and the probabilities of the respective causal relationships.

Abstract
A method, apparatus and computer program product are provided for constructing a diagnostic network model in a more efficient and timely manner and with improved consistency. A structured electronic representation of a document is automatically reviewed to identify the symptoms experienced by the complex system, the plurality of components of the complex system and the causal relationships between a failure of the respective components and the occurrence of the various symptoms. Respective probabilities can be associated with the causal relationships between the symptoms and the failure of the various components. A network model, such as a Bayesian network model, may then be automatically constructed to represent the symptoms, the components, the causal relationships between failure of the components and exhibition of the symptoms, and the probabilities of the respective causal relationships.
