noun
Definition 1: A research area concerned with formal approaches to representing knowledge, meaning, and inferential structure, especially in logic-based, ontological, and semantic systems [Russell, Norvig 2021].
Example in context: “The use of symbolic knowledge representation and reasoning as a way to resolve the lack of transparency of machine learning classifiers is a research area that lately attracts many researchers.” [Dervakos et al. 2022]
Definition 2: A method of formalizing knowledge in a structured representation, for example by means of ontologies, so that it can be processed and used for reasoning [Bakanach 2023/2024].
Example in context: “This article introduces a knowledge representation that combines an ontology on system engineering, a deductive reasoning on the connections between system components, and an inductive reasoning on the performance of these components in the current system configuration.” [Sijs et al. 2024]
