Última carta de Gabriel García

My research falls in the fields of natural language and computer
science. It forms a part of the digital humanities and as such is
interdisciplinary. It focuses in particular on the interface of
linguistics, computation, and logic. The objective is to proportion a
computational environment in which to analyse the syntax and semantics
of human language. In this way we aim to help move linguistics from a
paradigm which attempted by hand the derivation of analyses and
verification of grammars, to a paradigm in which the same is done
computationally, with the consequent enormous gain in economy and
reliability.
The framework in which this is done is (type) logical grammar. In this
approach grammar is reduced to logic: an expression is gramatical if
and only if an associated logical statement is a theorem of a
calculus. Thus parsing is deduction, and the calculus is constructive:
the proof of the grammaticality of an expression provides its
semantics in terms of the semantics of its words.
I have been pursuing this programme for 30 years. Recently I and my
students have developped the displacement calculus which generalizes
in a satisfactory way the classical treatment of continuity to
discontinuity. This has enabled me to implement a Prolog
parser/theorem-prover CatLog which efficiently analyses sentences
according to logical grammar and which generates their derivacions and
semantic readings in LaTeX: https://catlog3.cs.upc.edu

(For a putative categorial syntactic structure to be correct,
a proof net,
it has to contain a Girard ``long trip''.)
