The course "Introduction to Computational Linguistics" centers on the basic and fundamental concepts of this interdisciplinary area of Linguistics, Informatics and Cognitive Science. Our purpose is to cover a wide range of theoretical and technical issues from Speech Recognition and Synthesis to Natural Language Processing and Machine Translation. Significant topics from Semantics, Syntax, Morphology and Phonology will be introduced through the dynamic prism of several state-of-the-art computing tools, applications, models and theories. This course will use a methodology of empirical linguistic analysis and processing of natural language that includes regular expressions, language modeling, machine learning, morphological / syntactical parsing, and semantic analysis and representation.

In particular, the main aim of the course is to familiarize students with significant and on-going research questions and theoretical approaches in this field and to provide them access to various tools and applications, while at the same time introducing them to language coding through programming. Moreover, we will also focus on how linguistic theory is applied to the most up-to-date text processing techniques, word meaning and semantic interpretations. Theoretical and technical issues such as n-grams models, neighborhood density, Context-free Grammars, morphosyntactic tagging, vector semantics, computing with word senses will be supported by exercises and mini-projects that will enable students to use practice tools, corpora and apply various semantic algorithms.
