Grammars for Natural Languages: Methods, Tools and Lexical Resources for Their Efficient Processing
This habilitation thesis deals with the research on grammars for natural languages. It comprises my articles and papers on grammars for Czech and other languages, approaches to their integration into efficient parsers and lexical resources and relevant tools supporting the analysis. The first part deals with the concept of metagrammar --- a special kind of grammar that focuses on modularity and reduction of rules needed to describe the grammar of free word order languages. The methods of efficient parsing with the metagrammar as well as best-analysis selection techniques are discussed next. The applications of the developed parser are also tackled. The second part deals with morphological and lexical resources and tools for their building. It covers Czech morphological analyzer, wordnet and other lexical databases, ontologies, and word sketches. Various tools for creation of these resources (manual as well as fully automatic) are also presented.
