In recent years, research in natural language processing has increasingly focused on normalizing SMS messages. Different well-defined approaches have been proposed, but the problem remains far from being solved: best systems achieve a 11% Word Error Rate. This paper presents a method that shares similarities with both spell checking and machine translation… (More)
This paper presents a method of normalizing SMS messages that shares similarities with both spell checking and machine translation approaches. The normalization part of the system is entirely based on models trained from a corpus. Evaluated in French by tenfold cross-validation, the system achieves a 9.3% Word Error Rate and a 0.83 BLEU score.
This paper presents a tool for extracting and normalizing temporal expressions in SMS messages in order to automatically fill in an electronic calendar. The extraction process is based on a library of finite-state transducers that identify temporal structures and annotate the components needed for the time normalization task. An initial evaluation puts… (More)
