In the seminar the subject of mathematical (computational) linguistics is defined, its foundations and relation to related fields such as: general linguistics, computer science, artificial intelligence, various special fields of mathematics (especially the theory of formal languages and automata theory, algebra and other). The main objective consists in how natural language (rather than a formal one, e.g. a programming language) can be processed by exact mathematical and computer science methods and formalisms, the stress being laid on morphology and syntax. The basic elements of the theory of

A. What is mathematical linguistics (ML in the sequel)?

  • definition of concepts: natural language processing (NLP); computational linguistics; formal linguistics; statistical linguistics; quantitative linguistics; algebraic linguistics; applied linguistics
  • relation of ML to mathematics, especially to: the theory of formal languages and automata; algebra; mathematical logic; probability and statistics; relation of ML to logic and to computer science
  • natural and artificial languages
  • computational analysis and synthesis of language: an outline
  • the tasks and objectives of ML

B. The foundations of the mathematical theory of languages: theory of formal languages and automata

  • formal generative grammars - Chomsky hierarchy of grammars and automata and its linguistic motivation
  • generative and recognizing procedures
  • recursion, recursive and recursively-enumerable languages
  • relation of formal grammars and languages (natural and artificial)
  • linguistically motivated examples of formal languages generated by these grammars
  • generative (weak) and explicative power of grammars

C. Immediate-constituent phrase-structure grammars

  • motivation and definition of immediate-constituent grammars
  • main features of immediate-constituent grammars
  • word order and hierarchical constituent structure
  • languages generated by immediate-constituent grammars and their properties
  • immediate-constituent tree

D. Introduction to transformational grammars

  • base component, phrase-structure, phrase-structure grammar, phrase-marker
  • transformation (preserving and nonpreserving meaning), transformational grammar
  • deep and surface structure of sentence
  • pros and cons of transformational grammars

E. Introduction to automata theory

  • automata as mathematical structures (devices)
  • types of automata from the viewpoint of their weak (generative) power and their relation to formal grammars: finite-state automata, pushdown store automata, linear-bounded automata, Turing machines
  • automata as acceptors and generators
  • examples of natural (sub)languages processed by various kinds of automata
  • the exploitation of finite-state automata for the processing of morphology and syntax of natural languages; two-level morphology

F. Dependency grammars

  • basic characteristics of dependency grammars
  • generative and explicative power of dependency grammars, their comparison with the Chomsky hierarchy and their status within the theory of formal languages
  • algebraic sentence representation in the dependency framework: directed graph
  • word order
  • projectivity and nonprojectivity of syntactic structures, unbounded dependencies
  • coordination and its description in dependency grammar
  • comparison of immediate-constituent and dependency grammars from the aspect of explicative power
  • convergence of immediate-constituent and dependency grammars: attempt at reconciliation

G. Categorial grammars

  • basic characteristics of categorial grammars
  • reasons for introducing categorial grammars and their adequacy for various types of languages
