SECOND CALL FOR PARTICIPATION

***************************************************
OMPHALOS CONTEXT-FREE LANGUAGE LEARNING COMPETITION
***************************************************
http://www.irisa.fr/Omphalos/
---------------------------------------------------

Update
------

The Omphalos Context-free Language Learning competition is still
running and has been quite succesful so far. Five of the first six
problems have been solved, so do not think that it is an impossible
task. We have added four new problems for everybody to try and solve.
Go ahead and try your best.

Note that everybody can participate, not only people from the ICGI
community or grammatical inference researchers.


Intro
-----

Omphalos is the first context-free language learning competition that
forms part of ICGI-2004 (See http://iit.demokritos.gr/icgi04/). The
task is to infer a model of a context-free language from unstructured
examples (both positive and negative) and to use that model to label a
set of test sentences as being either in or out of the language.


The Competition Task
--------------------

We have generated some context-free grammars. For each grammar we have
labeled a set of sentences indicating whether or not those sentences
can be generated from that grammar. The goal of the competition is to
infer a model of each language (such as a grammar) using the training
data. You then need to tag new sentences, indicating whether the
sentences are in the language or not.
