Large Scale Learning for Natural Language Processing

We describe a neural network architecture that given a sentence,
outputs a host of language processing predictions: part-of-speech
tags, chunks, named entity tags, semantic roles, semantically similar
words and the likelihood that the sentence makes sense (grammatically
and semantically) using a language model. The entire network is
trained jointly on all these tasks using weight-sharing, an instance
of multitask learning. All the tasks use labeled data except the
language model which is learnt from unlabeled text and represents a
novel way of performing semi-supervised learning for the shared
tasks. We show how both multitask learning and semi-supervised
learning improve the generalization of the shared tasks, resulting in
a learnt model with state-of-the-art performance.
