Action rules are built from atomic expressions called atomic action terms and they describe possible transitions of objects from one state to another. They involve changes of values within one decision attribute. Association action rule is similar to an action rule but it may refer to changes of values involving several attributes listed in its decision part. Action paths are defined as sequences of association action rules with the assumption that the last rule in a sequence is as action rule. Early research on action rule discovery usually required the extraction of classification rules before constructing any action rule. Newest algorithms discover action rules and association action rules directly from an information system. This paper presents a strategy for generating association action rules and action paths by incorporating the use of meta-actions and influence matrices. Action paths show the cascading effect of meta-actions leading to a desired goal.
