Explanation of reasoning in expert systems is necessary for debugging the knowledge base, for facilitating their acceptance by human users, and for using them as tutoring systems. Influence diagrams have proved to be effective tools for building decision-support systems, but explanation of their reasoning is di±cult, because inference in probabilistic graphical models seems to have little relation with human thinking. The current paper describes some explanation capabilities for in°uence diagrams and how they have been implemented in Elvira, a public software tool.
