Friday of next week (March 22, 2019), at 16:00, in room 3074 of the
Arts Building (TCD), Prof. Heiko Vogler will speak.
Title:
Parsing of natural languages - some ideas
Abstract:
We consider parsing of natural language sentences into (continuous
or discontinuous) phrase structure trees or (projective or non-projective)
dependency trees. We recall the known model of linear context-free rewriting
systems (LCFRS), discuss a deficit of LCFRS, and present an alternative:
hybrid grammars. We show how to parse with hybrid grammars, how to induce and
train hybrid grammars from a corpus, and discuss some experiments.
The talk is based on the paper [1].
