Action Rules

Abstract

There are two frameworks for generating action rules: loosely coupled and tighty coupled [21]. The loosely coupled framework is often called rule-based. It is based on pairing certain classification rules which have to be discovered first by using for instance algorithms such as LERS [13] or ERID [5], [7]. The tightly coupled framework is often called object-based and it assumes that action rules are discovered directly from a database [6], [16], [18]. Classical methods for discovering them follow algorithms either based on frequent sets (called action sets) and association rules mining [3] or they use algorithms such as LERS or ERID with atomic action sets used as their starting step.
