The UNL Distinctive Features: Inferences from a NL-UNL Enconverting Task

This paper reports on the distinctive features of the Universal Net- working Language (UNL). We claim that although UNL expressions are sup- posed to be unambiguous, UNL itself is able to convey vagueness and indeter- minacy, as it allows for flexibility in enconverting. The use of UNL as a pivot language in interlingua-based MT systems is also addressed.
