For questions related to the acquisition of rules that describe conditions and consequences related to actions, objects, or complex behaviors with or without certainty metrics. This may be from constructive algorithms that search for rules describing observations or from the translation of observations directly into logical constructs via circuitry.

An older term, based on the presumption that rules are the primary representation of knowledge, is, "Knowledge acquisition." In the context of AI research with a broader perspective, rule acquisition is a subset of knowledge acquisition.
