Using Machine Learning Techniques to Build a Comma Checker for Basque 
 In this paper, we describe the research using machine learning techniques to build a comma checker to be integrated in a grammar checker for Basque . After several experiments, and trained with a little corpus of 100,000 words , the system guesses correctly not placing commas with a precision of 96% and a recall of 98%. It also gets a precision of 70% and a recall of 49% in the task of placing commas . Finally, we have shown that these results can be improved using a bigger and a more homogeneous corpus to train, that is, a bigger corpus written by one unique author .
