LING315 - Introduction to Syntax.

(Link to course syllabus in PDF format)

This course investigates the syntax (sentence structure properties) of human language. First, it takes into account the need for a scientific model to explain human knowledge of language that also makes predictions about its representation in the mind. Second, it explores in detail the fact that different languages, even those that clearly do not share a common recent past, share many structural properties.

LING 316 - Aspects of Meaning.

(Link to course syllabus in PDF format)

This course focuses on the core aspects of the representation of meaning in human language. It adopts a compositional approach to meaning: how humans combine basic linguistic units (e.g. words or lexical items) into complex linguistic expressions that allow them to represent the complex aspects of reality and thought in natural language. More specifically, the course focuses on the connection between the structure of linguistic expressions (i.e. their syntax) and the construction of meaning (semantics). It adopts a simple but precise and powerful approach to meaning, focusing on the conditions under which complex linguistic expressions are true or not true. The students will become familiar with various tools that are relevant for a theory of meaning in human language, including set theory, propositional and predicate logic, (generalized) quantifier theory, scope and polarity.

 LING 515 - Generative Syntax.

(Link to course web page)

In the Generative framework, syntactic structure is generated by a formal rule system and by applying constraints to its output. Some of these rules and constraints are hypothesized to be innate, or "unlearned" (perhaps a species specific system). That is supported by how human language acquisition or grammar growth takes place, and by the observation of striking structural similarities across different human languages. Other aspects of our linguistic knowledge appear "learned", i.e. determined by an interaction of human biology and particular linguistic inputs, motivating different aspects of variation among human languages. This class introduces this so-called "Principles and Parameters" approach to the analysis of human syntactic knowledge, focusing on how the various postulated ("simple") rules and constraints interact to generate ("complex") structures, characteristic of natural language sentences (such as the one you are now reading, and understanding).

LING615/815 - Advanced Syntax/Seminar: Syntactic Theory.

(Link to course syllabus in PDF format)

This course introduces students to innovations in syntactic theory that have been proposed within the last decade. Students will move beyond the introductory-text level and extend their knowledge of Principles & Parameters approaches to syntax through discussion of the goals of Minimalist Syntax and its hypotheses about design aspects of the human faculty of language. The course explores in detail how postulated minimalist primitives and operations interact to generate the (complex) structures that are characteristic of natural language sentences.

LING 394 - Topics in Linguistics: Language, Mind and Human Experience

This course explores different aspects of language structure and interpretation and how they relate to human language acquisition, language processing, language change and innovation. One focus is on linguistics as a branch of cognitive science. The questions we consider include: What aspects of language cognition and linguistic experience allow children to learn at an amazing speed the many complex aspects of their language? (e.g. by age three children have mastered most of the core properties of their native language). What do we do in order to understand so successfully what we hear or read, to the point that we can be misled by our own processing choices (something humor often explores: “I shot an elephant in my pajamas… How he got into my pajamas I’ll never know”)? How does one account for variation across languages, regarding the representation of structure and meaning (a sentence like ‘Bill saw us’ requires that both Bill and us be pronounced in English, different from many languages of the world in which either or both nouns can be absent)?  How does this sort of variation arise, and how does human linguistic knowledge yield language change, that is, gives rise to innovating grammars by new generations? In the absence of linguistic input from native speakers, can children create a natural language from scratch?

LING 211 - Introduction to Language.

(Link to course web page)

Human beings have always been curious about the uniquely human possession, human language-about its structure, its diversity, its use and its effects on others. This course explores the human capacity for language. We begin with the discussion of the uniqueness of human language and then review major properties of language structure including sound systems, word and sentence structure, meaning and their use. We explore how these properties relate to language acquisition, processing/computation, conversation and writing. The course also considers the rich variation of language in terms of language change, dialects, and identity.

LING 212 - The symbolic analysis of language.

(Link to course syllabus in PDF format)

This course is an introduction to mathematical concepts and techniques used in semantic theory. The main focus of the course is teaching how to construct models of natural language with these mathematical tools and to evaluate to which extent these models succeed in approximating natural language. I start defining the scope and goals of formal semantic theory and introducing the notion of compositionality. After covering the basics of set theory, statement/propositional logic (first-order) predicate logic, their contribution and limitations, I discuss the theory of Generalized Quantifiers, properties of determiners and polarity items, the derivation of scope ambiguities and anaphora, and the basics of model theory. Finally, I address the interaction between languages, grammars and automata. The course is also directed to students interested in issues related to computational linguistics/Natural Language Processing.

LING 492/792 - Comparative syntax: Variation and Change in the Romance Languages.

(Link to course syllabus in PDF format)

This course discusses recent Principles & Parameters approaches to syntactic phenomena common to the Romance languages, compared to each other and to different languages: English and other Germanic languages and, to a lesser extent, Arabic, Celtic, Chinese, Greek and Japanese. The course focused on the interaction between functional categories, features (Case, agreement, tense), thematic properties and movement in grammatical theory, in order to account for the cross linguistic variation with respect to verb movement and argument licensing, null arguments, negation, non-finite complementation, control, argument/adjunct distinctions, and cliticization. The course also explored some of these phenomena from the perspective of theories or language change and acquisition.

LING 492.003 - Introduction to computational linguistics and natural language processing.

(Link to course web page)

This course has two components: i) it covers NLP research in the areas of morphology, syntax, semantics and the lexicon; ii) it provides a short introduction to programming, with assignments directed to NLP. Some topics the students will become familiar with are finite state automata and regular expressions, part-of-speech (POS) tagging, context-free grammars, tools for sentence parsing, semantic analysis and unification. The course also introduces natural language applications in information extraction/retrieval and machine translation. This can be taken as a beginning course in the field, but it is also useful for students who want to be able to use computers to manipulate human language as their object of study in different fields.

Ling 792.004 - Formal and stochastic methods in linguistics research.

(Link to course web page)

This course presents and discusses rule-based/symbolic and statistical/stochastic approaches to linguistics and computational linguistics, evaluating some of their individual contributions to the field and how they can be combined with different purposes in natural language processing (NLP). I will spend some time covering basic concepts/techniques necessary for students to understand the more advanced material. Some of the topics covered will be lexical analysis, corpora tagging, morphological and syntactic parsing/analysis, semantic analysis and a couple of NLP applications, including information extraction/retrieval, machine translation and, to a lesser extent, language recognition/generation.
