Natural Language Human-Computer Dialogue: Menu-Based Natural Language and Visual Performance
… to determine design principles for menu-based natural language (MBNL) interfaces and to provide evidence for the nature of visual search processes with menu-based systems. The effects of window size, window activity, and query length were investigated. Window size was manipulated as a …

Multithreaded Natural Language Processing Tasks
… towards multithreaded versions of traditional natural language processing systems. This thesis work has two main contributions towards multithreaded versions of a natural language processing systems: </p> <p> 1. Implementation of data parallelism to improve performance of lexical analysis and …

Parsing of Natural Language Requirements
… a program which translates most of the natural language requirements into the framework, and a novel approach to parts of speech analysis.</p>

Evaluation of Natural Language Processors
Despite a large amount of research on developing natural language understanding programs, little work has been done on evaluating their performance or potential. The evaluations that have been done have been unsystematic and incomplete. This has lead to uncertainty and confusion over the …

Building representations from natural language
… representations from descriptions embedded in natural language. For example, in the sentence 'The girl walked to the table', my system produces a description of movement along a path (the girl moves on a path to the table), instantiating a general purpose trajectory representation that models …

Natural language and spatial reasoning
Making systems that understand language has long been a dream of artificial intelligence. This thesis develops a model for understanding language about space and movement in realistic situations. The system understands language from two real-world domains: finding video clips that match a spatial …

Misinformation Identification Using Natural Language Processing
… problem of misinformation identification using natural language processing (NLP). Given a claim, our approach classifies a claim as true, partly true or false using a set of news articles whose contents are related to the claim. The set of related articles, collected from reputable sources, …

Natural Language Interfaces to Conceptual Models
… currently requires the use of formal query languages (e.g., SeRQL or SPARQL) which pose significant difficulties for non-expert users. One way to lower the learning overhead and make ontology queries more straightforward is through a Natural Lan- guage Interface (NLI). While there are …

Investigating Natural Language Interactions in Communities
In this work, we investigate language use in communities. First, we study how authors of scientific textsexplain how their paper relates to another. We propose a new task, relationship explanation generation for scientific texts, by using in-line citation text as a source of evidence. We introduce …

Descriptive Phrases: Understanding Natural Language Metadata
… over the data. Deeper levels of analysis include language analysis, starting from purely string-based (keyword) approaches, continuing with syntactic-based approaches and now semantics is about to be included in the processing loop. Metadata gives a leverage over the data. Often a natural …

Necessary Bias in Natural Language Learning
This dissertation investigates the mechanism of language acquisition given the boundary conditions provided by linguistic representation and the time course of acquisition. Exploration of the mechanism is vital once we consider the complexity of the system to be learned and the non-transparent …

Domain Adaptation in Natural Language Processing
Although we focus on domain adaptation in natural language processing in this thesis, most of the analysis of the problem and the proposed domain adaptation techniques are not restricted to natural language processing problems but can be generally applied to most classification tasks when the …

Integrating natural language with molecular structure
… Of particular note, multimodal models combining natural, human language with molecular structure are poised to be a critical tool for discovering these solutions. In this dissertation, we will focus on enabling natural language processing, and particularly natural language itself, to serve as a …

Understanding time in natural language text
… about those events. It is thus an important natural language processing (NLP) task to understand time. This thesis advances the study of time by developing new insights into some aspects of the problem of reasoning about time in text, new algorithmic and machine learning approaches, and new …

Reasoning about quantities in natural language
… interaction. However, little work from the Natural Language Processing community has focused on quantitative reasoning. In this thesis, we investigate the challenges in performing automated quantitative reasoning over natural language text. We formulate several tasks to tackle some of the …

Implicit learning of natural language syntax
… learning research to the investigation of language acquisition. The results of six experiments are reported. In terms of design, all experiments consisted of (i) a training phase, during which subjects were trained on a miniature linguistic system by means of different exposure conditions, …
