[Corpora-List] [CORPORA-List] RE: Evaluating Sentence Aligners

[Olivier Kraif]

Dear Mike,
according to my own experience, stemming and lemmatizing may improve 
results for lexical level aligning, but not for sentence aligning when 
it is based on surface clues (sentence length, identical chains and 
cognate search, etc.).
