Abstract :
This conference examines the behavior of selection in language.
Selection is that property of a word or phrase which determines the
paradigmatic behavior of its neighbors.
Predicates select arguments; but what is selected for, a type, a
feature, something else? Is selection defeasible?  Do arguments
themselves have any selectional properties? Do grammatical functions
have selectional behavior?
In this course, we study the formal mechanisms responsible for
argument and adjunct selection in language. I will present a theory of
lexically type-driven semantic selection that expands the operations
available in composition. Building explicitly on Generative Lexicon's
richer inventory of compositionality, I explore the type language and
logic necessary to model the mechanics of selection. Words encode
local context as typing information. The compositional rules of the
language refer to these types. The operations possible during
composition for these types are: i. selection, ii. accommodation, and
iii. coercion (exploitation and introduction). As an illustration of
this theory, I explore the phenomena of nominal and verbal polysemy,
and verbal alternations.
