This course is a graduate introduction to natural language processing - the study of human language from a computational perspective. It covers syntactic, semantic and discourse processing models, emphasizing machine learning or corpus-based methods and algorithms. It also covers applications of these methods and models in syntactic parsing, information extraction, statistical machine translation, dialogue systems, and summarization. The subject qualifies as an Artificial Intelligence and Applications concentration subject.
Introduction to the current research questions in phonological theory. Topics include: metrical and prosodic structure; features and their phonetic basis in speech; acquisition and parsing; phonological domains; morphology; and language change and reconstruction. Activities include problem solving, squibs, and data collection. The year-long Introduction to Phonology reviews at the graduate level fundamental notions of phonological analysis and introduces students to current debates, research and analytical techniques. The Fall term reviews issues pertaining to the nature of markedness and phonological representations - features, prosodies, syllables and stress - while the second term deals with the relation between the phonological component and the lexicon, morphology and syntax. The second term course will also treat in more detail certain phonological phenomena.
This course provides an overview of the distinctive features which distinguish sound categories of languages of the world. Theories which relate these categories to their acoustic and articulatory correlates, both universally and in particular languages are covered. Models of word recognition by listeners, features, and phonological structure are also discussed. In addition, the course offers a variety of perspectives on these issues, drawn from Electrical Engineering, Linguistics and Cognitive Science.
Central topics in language processing. The structure of language. Sentence processing. Discourse processing. Morphological processing. The storage and access of words in the mental dictionary. Speech processing. The relationship between the computational resources available in working memory and the language processing mechanism. Ambiguity resolution. Discussion of computational modeling, including connectionist models. The relationship between language and thought. Issues in language acquisition including critical period phenomena, the acquisition of speech, and the acquisition of words. Experimental methodologies such as self-paced reading, eye-tracking, cross-modal priming, and neural imaging methods.
The goal of this course is to prepare you to engage in experimental investigations of questions related to linguistic theory, focusing on phonetics and phonology.
The Creole languages spoken in the Caribbean are linguistic by-products of the historical events triggered by colonization and the slave trade in Africa and the `New World'. In a nutshell, these languages are the results of language acquisition in the specific social settings defined by the history of contact between African and European peoples in 17th-/18th-century Caribbean colonies. One of the best known Creole languages, and the one with the largest community of speakers, is Haitian Creole. Its lexicon is primarily derived from varieties of French as spoken in 17th-/18th-century colonial Haiti; yet some of its structures seem to have emerged under the influence of African languages, mostly from West and Central Africa. And yet other properties seem to have no analogues in any of the source languages. Through a sample of linguistic case studies focusing on Haitian Creole morphosyntax, we will explore creolization from a cognitive, historical and comparative perspective. Using Haitian Creole and some of its Caribbean congeners as test cases, we will evaluate various hypotheses about the development of Creole languages and about the role of first- and second-language acquisition in such development. We will also explore the concept of Creolization in its non-linguistic senses. Then we will address questions of "Caribbean identities" by examining a sample of Creole speakers' attitudes toward the Creole language and the corresponding European language and toward the African and European components of their ethnic make-up.
