Discriminating between Similar Languages with Word-level Convolutional Neural Networks
TL;DR: The main approach is a word-level convolutional neural network (CNN) that learns task-specific vectors with minimal text preprocessing that makes a viable approach to discriminating between similar languages.

A Nontrivial Sentence Corpus for the Task of Sentence Readability Assessment in Portuguese
TL;DR: A nontrivial sentence corpus in Portuguese is generated, taking advantage of a parallel corpus of simplification, in which each sentence triplet is aligned and has simplification operations annotated, being ideal for justifying possible mistakes of future methods.
Revisiting the readability assessment of texts in portuguese
TL;DR: In this article, a readability checker is used to classify texts in Portuguese, considering different text genres, domains and reader ages, using naturally occurring texts, and address three key research questions: (1) which machine learning algorithm produces the best results? (2) which features are relevant? (3) Do different text genre have an impact on readability assessment?

TL;DR: It is shown that gross errors present even in state-of-the-art systems can be avoided and that an accurate acoustic model can be built in a hierarchical fashion and that even with a small amount of data, accurate and robust recognition rates can be obtained.
