The sources were 15 Brazilian newspapers located all over the country. We have chosen 30 short articles from each author, thus summing up 3000 pieces of documents. The articles usually deal with polemic subjects and express the authors personal opinion. In average, the articles have 600 tokens (words) and 350 Hapax (words occurring once). One aspect worth of remark is that this kind of articles can go through some revision process, which can remove some personal characteristics of the texts. Besides, authorship attribution using short articles poses an extra challenge since the number of features that can be extracted are directly related to the size of the text.
