************************************************************************ ****** CTL@CILTA Categorial Type Logic and Italian Corpora Lectures held by prof. M. MOORTGAT, University of Utrecht ************************************************************************ ****** The framework of categorial grammar was introduced by Jim Lambek in his 1958 and 1961 papers. These systems, despite their great mathematical elegance, have their limitations when it comes to dealing with real life problems in computational linguistics. The structural properties of the original categorial grammars are hard-wired. Issues of structural variation, a core concern of linguistic theory, are not easily dealt with if the structural component of the grammar is fixed. Over the past years, a new categorial grammar design has emerged, as a result of the surge of interest in resource-conscious models of computation. For current type-logical grammars, cross-linguistic variation arises from the interplay between a core module, capturing grammatical INVARIANTS, and a flexible STRUCTURAL MODULE. The vocabulary of type-forming operations is extended with explicit CONTROL operators that make it possible to keep structural options firmly anchored in lexical type assignment. This course offers an introduction to the theoretical foundations of present-day categorial type logics, and their computational use in natural language processing. The course has a double emphasis: - Italian. We look at some core phenomena of Italian grammar, and see how they fit within the broader landscape of cross-linguistic variation. - Corpus-based computational linguistics. We discuss the applicability of categorial techniques to the exploitation of the Cilta corpus, drawing on experiences with the annotation of the Spoken Dutch Corpus and its categorial analysis. Course structure: 1a week: 8-12 September "Grammatical invariants. Constants of the base Logic, residuation laws, frame models for structured linguistic expressions." 2a week: 15-19 September "Meaning assembly. The Curry-Howard interpretation." 3a week: 22-26 September "The logic of variation. Structural laws relating form and meaning assembly." 4a week: 29 September - 2 October 2 parallel sessions: Linguistic issues - "Lexical versus derivational semantics." Computational issues - "The computational system: sequent proof search and proof nets." 5a week: 6-10 October "Learning: solving lexical and structural equations. Incremental processing." 6a week: 13-17 October (held by dr. R. Moot) "Corpus-based categorial grammar induction." The lectures will be held at CILTA with the following provisional weekly schedule: Monday - Discussion and Lecture (prof. M. Moortgat) Tuesday - Lecture (prof. M. Moortgat) Friday - Exercises in computer lab (dr. R. Bernardi) ------------------------------------------------------------------------ ----- Please refer to CILTA website for further information and up-to-date lecture schedule: http://www.cilta.unibo .it/Portale/Seminars%20CLT%20at%20CILTA.html Contact Email address: f.tamburini_(on)_cilta.unibo.it
