Basic course of computational processing and understanding of natural languages. Automatic methods of morphological and syntactic analysis including modern statistical methods of result disambiguation will be discussed. Two-level morphology, tagging and language models, Viterbi algorithm, grammars, chart parsing, probabilistic grammars.

Syllabus of lectures:

1. Introduction, overview of applications. 2. The Perl programming language. 3. Corpora, first applications. 4. Linguistic terminology, layers of natural language processing. 5. Accuracy evaluation. 6. Dictionaries and morphological tags. 7. Two-level morphology, morphonology. 8. Morphology and context-free grammars. 9. Morphology and unification grammars. 10. Tagging (disambiguation of morphological analysis). 11. Spellchecking. 12. Constituency syntax. 13. Dependency syntax.

Study Objective:

Knowledge of basic methods of natural language processing from tokenization to the level of syntactic parsing. Ability to implement some of them in Perl. Ability to work with annotated corpora and existing freely available tools such as taggers and parsers.
