Abstract
Natural language offers several phenomena which depend on semantic
motivations for grammaticality. Polarity items (PIs) are a case in
point: their distribution depends on the monotonicity properties of
their licenser. The same properties justify (some) natural reasoning
inferences as well. In the talk I will present a system able to:
1. encode this semantic information,
2. take advantage of them to account for PIs distribution, and
3. give a proof theoretical account of natural reasoning inferences.
The analysis presented results from the embedding of the natural logic
proposed in [van Benthem 1986] and [Sanchez 1991] into a Lambek
calculus extended with unary operators [Moortgat 1997]. The first
part of the talk will be used to give the necessary background,
introducing the concept of natural logic, the algorithm used by
Sanchez and the extended Lambek calculus.
