During language acquisition, children are tasked with the challenge of determining which words can appear in which syntactic constructions. This has been long recognized as a learnability paradox. On one hand, there are generalizations that children must learn. On the other hand, language is known for its arbitrariness, so children also need to…

In education, machine learning (ML), especially deep learning (DL) in recent years, has been extensively used to improve both teaching and learning. Despite the rapid advancement of ML and its application in education, a few challenges remain to be addressed. In this thesis, in particular, we focus on two such challenges: (i) data scarcity and…

This dissertation sets out to find an answer to the question why not all logically conceivable patterns are found typologically. In other words, my aim is to find paradigmatic gaps and explain their absence. In doing so, I use the mathematical notion of monotonicity (which is a more general term to convey order preservation) as proposed by Graf…

Artificial intelligence (AI) that is based upon semantic search has become one of the dominant means for accessing information in recent years. This is particularly the case in mobile contexts, as search-based AI are embedded in each of the major mobile operating systems. The implications are such that information is becoming less a matter of…

Just as pronouns like "she" and "he" make anaphoric reference to individuals, English words like "that" and so can be used to refer anaphorically to a proposition introduced in a discourse: "That's true; She told me so". Much has been written about individual anaphora, but less attention has been paid to…

The primary concern of this dissertation is determining the distinction between semantics and pragmatics and how context sensitivity should be accommodated within a semantic theory. I approach the question over how to distinguish semantics from pragmatics from a new angle by investigating what the objects of a semantic theory are, namely…

Accurate recovery of predicate-argument dependencies is vital for interpretation tasks like information extraction and question answering, and unbounded dependencies may account for a significant portion of the dependencies in any given text. This thesis describes a Generalized Categorial Grammar (GCG) which, like other categorial grammars,…

This dissertation makes substantial contributions to both the theoretical and computational treatment of information structure, with an eye toward creating natural language processing applications such as multilingual machine translation systems. The aim of the present dissertation is to create a grammar library of information structure for the…

Classifier languages are often described as lacking genuine number morphology and treating all common nouns, including those conceptually count, as an unindividuated mass. This study argues that neither of these popular assumptions is true, and presents new generalizations and analyses gained by abandoning them. I claim that no difference exists…

Advancements in technology have greatly influenced how students write, the ways they interact with readers, and the genres they create. In order to reflect real-world writing behaviors in the assessment setting and to be able to generalize test-takers' performance from the assessment to their true writing ability, the current study investigated…

Accurate and rapid word recognition requires highly-specified phonological, orthographic, and semantic word-specific representations. It has been established that children acquire these representations through phonological decoding in a process known as orthographic learning. Studies examining orthographic learning and its predictors have thus far…

This dissertation presents a formal theory of Serbo-Croatian grammar. The theory predicts acceptable form/meaning pairs for a substantial chunk of Serbo-Croatian. In particular, we analyze Serbo-Croatian declarative and interrogative main clauses, embedded clauses, a couple of different types of nominal modification, control and predication, as…

Landau (2000) distinguishes between P(artial) C(ontrol) and E(xhaustive) C(ontrol): PC predicates like hope admit a subset relation between controller and controllee (e.g., "Kim hoped to gather at noon." [controllee = Kim and contextually salient others]); EC predicates like "try" do not (*"Kim tried to gather at…

Extracting and representing semantic information from large scale corpora is at the crux of computer-assisted knowledge generation. Semantic information depends on collocation extraction methods, mathematical models used to represent distributional information, and weighting functions which transform the space. This dissertation provides a…

The present thesis investigates the role of semantic alternatives and logical strength in a number of empirical domains. Firstly, the thesis deals with the semantic contribution of focus on (bound) pronouns (chapters 2-3). The main results are as follows: First, focus on bound pronouns is interpreted by an operator (Rooth 1992b) in the scope of…
