AfriBERTa: Towards Viable Multilingual Language Models for Low-resource Languages
(University of Waterloo, 2022-08-29)There are over 7000 languages spoken on earth, but many of these languages suffer from a dearth of natural language processing (NLP) tools. Multilingual pretrained language models have been introduced to help alleviate ... -
Beyond Natural Language Processing: Advancing Software Engineering Tasks through Code Structure
(University of Waterloo, 2024-01-25)Machine learning-based approaches have been widely used to address natural language processing (NLP) problems. Considering the similarities between natural language text and source code, researchers have been working on ... -
Concept Mining: A Conceptual Understanding based Approach
(University of Waterloo, 2009-05-21)Due to the daily rapid growth of the information, there are considerable needs to extract and discover valuable knowledge from data sources such as the World Wide Web. Most of the common techniques in text mining are ... -
Controlled Generation of Stylized Text Using Semantic and Phonetic Representations
(University of Waterloo, 2022-01-21)Neural networks are a popular choice of models for the purpose of text generation. Variational autoencoders have been shown to be good at reconstructing text and generating novel text. However, controlling certain aspects ... -
Cross-Domain Sentence Modeling for Relevance Transfer with BERT
(University of Waterloo, 2019-12-16)Standard bag-of-words term-matching techniques in document retrieval fail to exploit rich semantic information embedded in the document texts. One promising recent trend in facilitating context-aware semantic matching has ... -
Disentanglement of Syntactic Components for Text Generation
(University of Waterloo, 2022-02-18)Modelling human generated text, i.e., natural language data, is an important challenge in artificial intelligence. A good AI program should be able to understand and analyze natural language, and generate fluent and accurate ... -
Distributions in Semantic Space
(University of Waterloo, 2024-04-26)This thesis is an investigation of the powerful and flexible applications of analyzing empirical distributions of vectors within latent spaces. These methods have historically been applied with great success to the domain ... -
Emotion-Aware and Human-Like Autonomous Agents
(University of Waterloo, 2019-12-20)In human-computer interaction (HCI), one of the technological goals is to build human-like artificial agents that can think, decide and behave like humans during the interaction. A prime example is a dialogue system, where ... -
An Experimental Analysis of Multi-Perspective Convolutional Neural Networks
(University of Waterloo, 2018-05-16)Modelling the similarity of sentence pairs is an important problem in natural language processing and information retrieval, with applications in tasks such as paraphrase identification and answer selection in question ... -
Explore the In-context Learning Capability of Large Language Models
(University of Waterloo, 2024-05-10)The rapid evolution of Large Language Models (LLMs) has marked the beginning of a new age in AI capabilities, particularly in the domain of natural language understanding and processing. Among the forefront of these ... -
Extracting Non-Functional Requirements from Unstructured Text
(University of Waterloo, 2018-01-18)Non-functional requirements (NFRs) of a software system describe desired quality attributes rather than specific user-visible features; NFRs model stakeholder expectations about pervasive system properties such as performance, ... -
Facilitating Information Access for Heterogeneous Data Across Many Languages
(University of Waterloo, 2023-01-25)Information access, which enables people to identify, retrieve, and use information freely and effectively, has attracted interest from academia and industry. Systems for document retrieval and question answering have ... -
From Atoms to the Solar System: Generating Lexical Analogies from Text
(University of Waterloo, 2006)A <em>lexical analogy</em> is two pairs of words (<em>w</em><sub>1</sub>, <em>w</em><sub>2</sub>) and (<em>w</em><sub>3</sub>, <em>w</em><sub>4</sub>) such that the relation between <em>w</em><sub>1</sub> and <em>w</em>< ... -
Future Sight: Dynamic Story Generation with Large Pretrained Language Models
(University of Waterloo, 2022-08-23)Automated story generation has been an open problem in computing for many decades. Only with the recent wave of deep learning research have neural networks been applied to automated story generation tasks. Current deep ... -
GRS: Combining Generation and Revision in Unsupervised Sentence Simplification
(University of Waterloo, 2022-08-30)Text simplification is a task in the natural language processing field that alters a given text to reduce the structural and lexical complexity of the text while preserving the underlying meaning. We can classify existing ... -
'Healthy' Coreference: Applying Coreference Resolution to the Health Education Domain
(University of Waterloo, 2008-08-26)This thesis investigates coreference and its resolution within the domain of health education. Coreference is the relationship between two linguistic expressions that refer to the same real-world entity, and resolution ... -
