UNL Lexical Selection with Conceptual Vectors
Mathieu Lafourcade, Christian Boitet · 2002
When deconverting a UNL graph into some natural language LG, we often encounter lexical items (called UWs) made of an English headword and formalized semantic restrictions, such as "look for (icl>do, agt>person)", which are not yet connected t o lemmas, so that is it necessary to find a "nearest" UW in the UNL-LG dictionary, such as "look for (icl>action, agt>human, obj>thing)".Then, this UW may be connected to several lemmas of LG.In order to solve these problems of incompleteness and polysemy, we are applying a method based on the computation of "conceptual vectors", previously used successfully in the context of thematic indexing of French and English documents.
