[mrp-users] cross-lingual training data and companion dependency trees

[Stephan Oepen]

dear colleagues,

as of yesterday, an updated data package is available for prospective
MRP 2020 participants for download via the LDC.  the update adds
meaning representation training graphs for the cross-lingual track
(chinese AMR, czech PTG, german DRG and UCCA), as well as 'companion'
syntactic dependency parses for the english, czech, and german parser
inputs (irrespective of meaning representation frameworks).

we are in the process of updating the task web pages and will soon
issue a second (and final) call for participation.  but please feel
free to obtain the updated data package through the LDC already: if
you have entered an evaluation license for MRP 2020 already, the new
file is now available for download through your LDC account.  if you
do not hold the (no-cost) license yet, please submit the form below to
the LDC:

we anticipate a final data update about two weeks from today:
providing additional companion syntactic dependency parses for chinese
and companion (but not gold-standard) anchorings for english AMR and
english and german DRG, i.e. the meaning representation graphs in our
collection that are formally unanchored.  as with all companion data,
participants are free to use or ignore these additional resources.

also, please note that we invite nominations for additional
third-party resources (beyond the training and companion data provided
by us) but require that any additional data or pre-trained models be
'white-listed' (i.e. announced to everyone) beforehand.  the deadline
for additional nominations is monday, june 15; please see:

we feel the shared task is about to enter its active phase, with about
two months until the closing date for the evaluation phase.  in case
you have any questions or suggestions to the task co-organizers,
please do not hesitate to make contact with us at the
'mrp-organizers at nlpl.eu' mailing address.

best wishes, oe (for the task co-organizers)
