From 1997 to 2004
Goals
UNL is a proposal of a common language shared by people over the world in a
multilingual network. This long-term project is sponsored by the Institute of
Advanced Studies of the United
Nations University (unl
project/ias/unu)
UNL Features
UNL is a metalanguage devised to describe the informal aspects of sentence meaning in a sense very close to that. The UNL building blocks are:
• a set of Universal Words (UWs), i.e., a "theoretically universal dictionary of conceptual-words", a "UW dictionary", to which every word or expression of a natural language, that is every headword, is to be linked;
• a set of binary Relation Labels (RLs), i.e., a set of theoretically universal semantic and grammatical relations that hold between pairs of sentence components or between UWs;
• a set of Attribute Labels (ALs), i.e., a set of language-specific attributes that specify particular values of grammatical and pragmatic features of individual UWs.
• formulas of the type RL(UW1,UW2)
