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.
	~~== Syntax ==~~

	The UNL Ontology is a plain text file with a single entry per line. There are two possible representations for UNL Ontology entries: they can be either represented as [[Master Definition\|Master Definitions]] or as [[UNL Knowledge Base]] (UNLKB) entries.

	~~When represented as UNLKB entries, the UNL Ontology entries have the following format:~~

	{\|
	~~\|<UNL Ontology entry>~~
	~~\|::=~~
	~~\|<binary relation>"="<degree of certainty>";"~~
	\|-
	~~\|<binary relation>~~
	~~\|::=~~
	~~\|{icl, iof, equ, pof} "(" <source node> "," <target node> ")"~~
	\|-
	~~\|<source node>~~
	~~\|::=~~
	~~\|any existing UW~~
	\|-
	~~\|<target node>~~
	~~\|::=~~
	~~\|any existing UW~~
	\|-
	~~\|<degree of certainty>~~
	~~\|::=~~
	~~\|{0,1}~~
	\|}

	~~Where:<br >~~
	~~0 = false <br >~~
	~~1 = true <br >~~

	[[Master Definitions]], or simply MD, is an abbreviated form for representing the UNL Ontology entries, but they can be used only with "[[icl]]" relations. This is the technique used by the UNL Centre to represent the UW System.

	~~== Databases ==~~
