Knowledge and representation

The aim is to enable students to grasp the main theories and concepts needed to understand FH, from memory and language to representation. Particular emphasis will also be placed on the application domains of these theories, such as the semantic web, ontologies and taxonomy. UX methodologies related to website evaluation will also be covered.

Prerequisites correspond to module CO5SCCC0.
