REPORT vincia03d/IDIAP Noisy Text Categorization Vinciarelli, Alessandro EXTERNAL https://publications.idiap.ch/attachments/reports/2003/rr03-61.pdf PUBLIC Idiap-RR-61-2003 2003 IDIAP This work presents a system for the categorization of noisy texts. By noisy it is meant any text obtained through an extraction process (affected by errors) from media different than digital texts. We show that, even with an average Word Error Rate of around 50%, the categorization performance loss with respect to the clean version of the same documents is negligible.
