Dear ACL members,

We are happy to announce the 1st Shared task on Morphosyntactic Parsing, to be held jointly with Syntaxfest 2025.

Morphosyntactic parsing redefines the content-function boundary to differentiate 'morphological' from 'syntactic' elements. In our morphosyntactic data structure, content words are represented as separate nodes on a dependency graph, even if they share a whitespace-separated word, and both function words and morphemes contribute morphology-style features to characterise the nodes. This makes our format independent of wordhood decisions which are not well-defined across languages.

Interested parties are invited to join the mailing list to be involved in the competition. Participating teams will be invited to submit a paper describing their work to the workshop at SyntaxFest and to present it in a special session in the workshop.
