Short Abstract: The thesis presents a novel mechanism to get hints of explanation exploiting the capability of memory-based networks – Differential Neural Computers – to store data in memory and reusing it for inference. By tracking both the memory access at prediction time, and the information stored by the network at each step of the input sequence, it is possible to retrieve the most relevant input steps associated to each prediction. The mechanism is tested on two problems: a modified version of T-Maze and the Story Cloze Test task. The work studies also the influence of parameters and the adequacy of the extracted explanations.

Short Abstract: The work presents a supersense tagger based on Wikipedia and BabelNet. SuperSense tagging is a Natural Language Processing task that consists in annotating each entity in a text according to a general semantic taxonomy. In our case BabelNet is used as taxonomy, extracting the most used words and collecting the nouns that can indicate a category. Exploiting the is-a relations of BabelNet, then Wikipedia is annotated with the extracted concepts and used as dataset for the training of an SVM classifier based on the framework It Makes Sense.
