ELiRF-UPV at IberEval 2017: Stance and Gender Detection in Tweets

This paper describes the participation of ELiRF-UPV team at the two Spanish subtasks of the Stance and Gender Detection in Tweets on Catalan Independence track of the IberEval workshop. We tested several approaches based on different models and tweet representations. Our best approaches are based on neural networks with one-hot vector representation and Support Vector Machines using bag-of-ngrams of chars. We achieved the first place on the gender detection subtask and the fourth place on the stance detection subtask.
