These texts, called tweets, are<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>characterized by having a short length (140 characters) that is too small compared with the size of traditional genres.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>Consequently, users of these networks have developed a new form of expression that<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>includes SMS-style abbreviations, lexical variants, letters repetitions, use of emoticons, etc.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>The result is that current NLP tools can have problems to process and understand these short and noisy texts unless they are normalized first.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>The TWEET-NORM lexical normalization task proposes the automatic "cleansing" of a set amount of<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>tweets by identifying and normalizing, abbreviations, words with repeated letters, and generally<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>any out of the vocabulary (OOV) words, regardless of syntactic or stylistic variants.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>While there has been some progress in this field for English tweets there are very few<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>studies and resources available to date for Spanish.
