This paper describes our approach to the shared task: a Neural Network system based on a simple bidirectional LSTM (biLSTM) model. Since we have developed the system in the context of other related IberLEF 2019 shared tasks, we train multiple models simultaneously sharing some of the layers of the neural architecture between them. Furthermore, we also have applied a method for data augmentation given the scarcity of resources which were available.application/pdfengCopyright © 2019 for this paper by its authors.
