Abstract
FLORES, Víctor and HADFEG, Yahima. A method for generating explanations of results of an Expert System, using Speech Patterns and Ontology. RISTI [online]. 2017, n.21, pp.99-114. ISSN 1646-9895. https://doi.org/0.17013/risti.21.99-114.
Expert systems (ES) usually generate extensive inference-trees before showing to users a definitive result related to a complex dynamic system (DS) behavior. These inference-trees are not included in the results but it could provide additional information to understand the overall performance of a DS. They contain a set of statements that describe the knowledge about the truths of the DS plus a set of constraints that can give statements that must be true in the DS behavior. This document describes a method to generate explanations based on the conclusions reached by an ES respect to the DS behavior, using a specific ontology and discourse patterns. The input of the method is an intermediate- state tree (the inference-tree) and a specific knowledge-domain represented by the ontology. The document describes the software architecture to generate the explanations and the testing cases designed to validate the results in a complex real domain, such as the copper bioleaching domain.
