Title: Multiword Expressions
By Timothy Baldwin
Abstract:
Multiword expressions (MWEs) are word amalgams which are lexically,
syntactically, semantically and/or statistically idiosyncratic in some way,
and occur in a wide range of configurations including verbal idioms (e.g. "kick
the bucket"), verb particle constructions (e.g. "throw up") and coordinate
structures (e.g. "dull and boring"). In recent years, there has been increasing
awareness in computational linguistics of the need for specialised methods to
detect and capture the syntactic flexibility, semantic generalities and productivity
of MWEs. In this talk, I will document some of the difficulties posed by MWEs
for real-world NLP applications, and outline a range of methods which have
been proposed to tackle these issues.
