Title: On Learning and Applying Text Representations

Abstract:
Unsupervised learning text representations aims at converting natural
languages into vector representations. These vector representations
are used in bigger models such as neural networks to improve the
performances of supervised tasks. To evaluate the effectiveness
of these unsupervised learned text representations, people create
suites of natural language processing tasks. These tasks aims to
evaluate the capabilities of these text representations at improving a
variety of NLP tasks, including text classification, semantic
relatedness and similarity, question answering, sequence labeling,
etc. This thesis discuss our work on both sides. We develop methods to
train better language representations and also develop better NLP task
suites to evaluate these represen tations. Most of our pretrained
unsupervised models use Wikipedia as training data. We use Wikipedia
articles and categories to improve text classification and
natural language inference tasks. We use Wikipedia document structures
to learn sentence representations with discourse information. We also
use the hyperlink structures from Wikipedia to learn entity
representations. Along with these work we also propose a variety of
test suites with standardized tasks to evaluate text representations
in these aspects.

Zewei's advisor is Prof. Risi Kondor
