Course objectives
In this course the main principles of natural language processing are offered. The algorithmic description of the main language levels will be discussed, particularly, morphology, syntax, semantics and pragmatics. Also the resources of natural language data - corpora will be mentioned. The role of knowledge representation, inference and relations to AI will be touched as well.
Syllabus
  • Introduction to Computational Linguistics.
  • Natural language as a main tool of human communication. Language data in corpora, information about corpus linguistics.
  • Levels of description: phonetics and phonology, morphology, syntax, semantics and pragmatics. Traditional vs. formal grammars: representation of morphological and syntactic structures -- DAGs, meaning representation. Grammars: context-free, context-sensitive, logical - DCG, transformational. Generating and recognition: morphological, syntactic, sémantic. Parsing: morphological parser -- AJKA, syntactic -- KLARA, Techniques of analysis: top-down, bottom-up, mixed, heuristics. Problem of ambiguity and searching.
  • Electronic or machine readable dictionaries: representation of lexical knowledge. Types of the machine readable dictionaries: monolingual, thesauri, idiomatic, morphological dictionaries (stems), translation dictionaries, - bi- or multilingual, the ways of their formalization.
  • Semantic representation of sentece meanings: logical vs. lexical sémantics. The Compositionality Principle.
  • Semantic classification of verbs, valency frames, predicates, transparent intensional logic (TIL) and its application to semantic analysis of Czech sentences.
  • Pragmatics: sémantic and pragmatic nature of noun groups, discourse structure, deictic expressions, verbal and non-verbal contexts. Natural Language Understanding: semantic representation, inference and knowledge representations - are they the same? Structure of dialog systems.
