Whither
DOP?
ILLC Workshop, Friday 9 December 2005
Plantage Muidergracht 24
(NB: if room 3.27 turns out to be too small, we will move to T.201, Sarphatistraat 104, two minutes walking from the ILLC main venue, see map)
Organizers: Rens Bod, Remko Scha
and Khalil Sima`an
Now
that the DOP approach has entered its 15th year from its original conception,
the time has come to critically look back and think afresh about the future.
What went astray with DOP's statistical estimator and has it been solved? What
are the problems related to DOP's productive units, and how can they be
redressed? What else is still to be done in DOP? And how far can the model be
stretched?
DOP
has led to statistical extensions of Lexical-Functional Grammar, Head-driven
Phrase-Structure Grammar and Tree-Adjoining Grammar. It has been applied to
machine translation, speech understanding, music analysis, problem-solving and
equational reasoning. Can it be extended to other fields of cognition? What are
the counter-examples that DOP has to face? And what is its relation with
frameworks like Case-Based Reasoning and Probabilistic Inductive Logic
Programming?
This
workshop aims to provide an informal discussion platform on DOP and is open to
everyone. Each talk will discuss one or more open problems and will be followed
by ample discussion. The workshop is also meant to give an overview of the
projects and/or recently founded research groups on DOP at the
