Natural Language Processing (CS-UH 2216)
The field of natural language processing (NLP), also known as computational linguistics, is interested in the modeling and processing of human ("natural") languages. Examples of some of the advances of NLP include machine translation (as in Google Translate, which translates among 80 languages) and question answering (as in IBM’s Watson system, which won Jeopardy in 2011). This course covers foundational NLP concepts and ideas, such as finite state methods, n-gram modeling, hidden Markov models, part-of-speech tagging, context free grammars, syntactic parsing, and semantic representations. The course will survey a range of NLP applications such as information retrieval, summarization and machine translation. Concepts taught in class will be reinforced in practice by hands-on assignments.
Words (CADT-UH 1011)
Words, words, words. Words are the basic units of language. But how do they help us communicate our thoughts? How are they internally constructed? And how do they come together to form complex meanings? How are words from different languages similar, and how are they different? Do words reflect or shape our thought? Do they expand or constrain our imagination? This interdisciplinary course explores what words are and how we think of them. The course brings together insights and ideas from a number of fields: linguistics, philosophy, psychology, sociology, computer science, history, literature, religion, and visual arts to help answer these questions. Students will read materials from a variety of books and articles and discuss them in class, and they will engage in solving and creating language puzzles. Students will learn how to analyze words in terms of their form, function, and meaning in context. Term projects can range from collection and analysis of linguistic data to multidisciplinary artistic creations.
Habash, Nizar. Introduction to Arabic Natural Language Processing, Synthesis Lectures on Human Language Technologies, Graeme Hirst, editor. Morgan & Claypool Publishers. 187 pages, 2010. (PDF version from Publisher) (Amazon)
This book provides system developers and researchers in natural language processing and computational linguistics with the necessary background information for working with the Arabic language. The goal is to introduce Arabic linguistic phenomena and review the state-of-the-art in Arabic processing. The book discusses Arabic script, phonology, orthography, morphology, syntax, and semantics, with a final chapter on machine translation issues.
The chapter sizes correspond more or less to what is linguistically distinctive about Arabic, with morphology getting the lion's share, followed by Arabic script. No previous knowledge of Arabic is needed. This book is designed for computer scientists and linguists alike. The focus of the book is on Modern Standard Arabic; however, notes on practical issues related to Arabic dialects and languages written in the Arabic script are presented in different chapters.
