Abstract Categorial Grammars (ACGs) are a grammatical framework,
deriving from current type-logical grammars. They allow several
exisisting grammatical formalisms to be encoded.
One of the main features of an ACG is that it relates two
languages of linear lambda-terms (which generalize both string and tree
languages): an abstract one and an object one so that a same structure
at the abstract level can be realized on different object levels
(phonological, syntactical, semantic...), each abstract-object
relation corresponding to an ACG.
Based on intuitionnistic linear logic, which captures important
features (ressource consciousness and intuitionnism) of different
syntactical formalisms (LFG, CFG, TAG...), it enables their study and
their relation with other formalisms (phonological, semantic or
The course will present both the underlying theoretical approach and
the associated algorithms (proof search, lambda-term matching), and
the practical use (modelling of different formalisms, composition)
with the ACG developpment kit.
