[eu_members at aclweb dot org] Unsupervised Morpheme Analysis -- Morpho Challenge 2009
Morpheme Analysis -- Morpho Challenge 2009
Part of the EU Network of
Excellence PASCAL Challenge Program and organized in collaboration with CLEF.
Participation is open to all.
The objective of the Challenge is to design
a statistical machine
learning algorithm that discovers which morphemes
(smallest individually meaningful units of language) words consist of.
Ideally, these are basic vocabulary units suitable for different tasks,
such as text understanding, machine translation, information retrieval,
and statistical language modeling.
The scientific goals
* To learn of the phenomena underlying word construction
* To discover approaches suitable for a wide
range of languages
* To advance machine learning
Morpho Challenge 2009 is a follow-up to our previous Morpho
2005, 2007 and 2008. The task of Morpho Challenge 2009 is
similar to the Morpho Challenge 2008, where the aim was to find the
morpheme analysis of the word forms in the data. There are some changes in
the evaluation and a new Arabic task. New *Machine Translation* tasks are
added (from Finnish to English and from German to English) to evaluate the
performance of the morpheme analysis.
Participation in the previous
challenges is by no means a prerequisite
for participation in Morpho
Challenge 2009. Everyone is welcome and we hope to attract many
participating teams. The results will be presented in a workshop. Please read
the rules and see the schedule at the home page. The datasets are
available for download.
If you now decided to participate in Morpho
Challenge, please contact
the organizers and ask to be added in our
mailing list. We will use this mailing list to provide news about the
tasks, data and evaluations.
We are looking forward to an interesting
