UNL Ontology

The UNL Ontology, also known as the UW System, is a tree-like structure where UWs are interconnected through ontological relations: icl (is-a-kind-of), iof (is-an-instance-of), equ (is-equivalent-to) and pof (is-a-part-of). The UNL Ontology is claimed to improve the results of the enconversion process, as it can be used as a word sense disambiguation strategy; and the deconversion results, as it would compensate dictionary limitations.
