SWAT: Cross-Lingual Lexical Substitution using Local Context Matching, Bilingual Dictionaries and Machine Translation
Richard Wicentowski, Maria Kelly, Rachel Lee · 2010
We present two systems that select the most appropriate Spanish substitutes for a marked word in an English test sentence. These systems were official entries to the SemEval-2010 Cross-Lingual Lexical Substitution task. The first system, SWAT-E, finds Spanish substitutions by first finding English substitutions in the English sentence and then translating these substitutions into Spanish using an English-Spanish dictionary. The second system, SWAT-S, translates each English sentence into Spanish and then finds the Spanish substitutions in the Spanish sentence. Both systems exceeded the baseline and all other participating systems by a wide margin using one of the two official scoring metrics. 1
