Meeting Description:

Following the success of the first CoNLL Universal Dependencies Parsing shared
tasks 2017 and 2018 and the Semeval Semantic Dependency Parsing 2014 and 2015,
a special shared task is launched with this year an emphasis on the parsing of
Enhanced Universal Dependencies (often reflecting deeper syntactic structures,
represented as more complex graphs, than regular surface dependencies).

The IWPT 2020 Shared Task will be on Multilingual Parsing into Enhanced
Universal Dependencies (EUD). In recent years, Universal Dependencies (UD)—the
de-facto standard target representations in surface-syntactic dependency
parsing—have grown a second layer of structure, called enhanced dependencies,
where grammatical relations that cannot be adequately represented in pure
rooted trees are encoded, for example control relations and argument sharing
in relative clauses, shared dependencies involving coordinate structures, and
dependencies involving ellipsis. Enhanced dependencies call for non-tree
graphs with reentrancies, cycles, and empty nodes.

Data for the shared task consists of at least the treebanks in UD release 2.5.
that contain enhanced annotation, and potentially one or more additional
languages/treebanks. The task will be parsing from raw strings into EUD
according to the guidelines at
https://universaldependencies.org/u/overview/enhanced-syntax.html. On top of a
classic F-measure metrics, evaluation will measure performance per phenomenon
and will take into account the fact that not all treebanks cover all of the
phenomena listed in the EUD guidelines.
