Papers

  1. Findings of the Fifth Shared Task on Multilingual Coreference Resolution: Expanding Datasets for Long-Range Entities (2026)
    The fifth edition of the multilingual coreference shared task, held with CODI-CRAC 2026, again asked for mention detection and identity coreference clustering.
  2. Findings of the Fourth Shared Task on Multilingual Coreference Resolution: Can LLMs Dethrone Traditional Approaches? (2025)
    This overview reports the fourth edition of the multilingual coreference shared task at CODI-CRAC 2025. Participants had to detect mentions, including zero mentions in pro-drop languages, and cluster them by identity coreference. The data came from CorefUD 1.3, with 22 datasets in 17 languages used in the task; new…
  3. CorefUD 1.0: Coreference Meets Universal Dependencies (2022)
    Syntax has a shared multilingual annotation standard in Universal Dependencies, but coreference resolution has had no comparable standard: corpora define the phenomena differently and use different formats, so most systems are evaluated only on English OntoNotes.
  4. Coreference meets Universal Dependencies – a pilot experiment on harmonizing coreference datasets for 11 languages (2021)
    The report converts 17 existing coreference datasets for 11 languages into one scheme based on Universal Dependencies.
  5. Do UD Trees Match Mention Spans in Coreference Annotations? (2021)
    Coreference mention spans in most corpora are plain token intervals, drawn without reference to syntax. The paper asks how often those spans match the subtrees of UD trees. It hand-checks mismatches in nine CorefUD datasets for eight languages. In eight of the nine, the trees come from UDPipe; English-GUM is the only…
  6. CoNLL 2018 Shared Task: Multilingual Parsing from Raw Text to Universal Dependencies (2018)
    This overview describes the second CoNLL shared task on parsing raw text into UD. Systems start from raw text, with no gold segmentation or tags, and are scored on 82 test treebanks, with macro-averaged LAS and two new metrics, MLAS (labels plus morphological features) and BLEX (lemmas plus labels). Eight new…
  7. CoNLL 2017 Shared Task: Multilingual Parsing from Raw Text to Universal Dependencies (2017)
    The shared task asks systems to parse raw text, with no gold tokenization, sentence splitting or tags, into UD trees for 49 languages.
  8. Udapi: Universal API for Universal Dependencies (2017)
    As UD and the CoNLL-U format spread, ad hoc scripts for processing treebanks became a common source of subtle bugs, such as forgetting to renumber nodes after a deletion.
  9. Coordination Structures in Dependency Treebanks (2013)
    A dependency tree cannot show the symmetric relation between conjuncts without a convention, so every treebank picks one.
  10. Formemes in English-Czech Deep Syntactic MT (2012)
    A formeme is a short label for the surface morpho-syntax of a node in a deep dependency tree. It has three parts: a syntactic part of speech, an optional preposition or conjunction, and a form such as a case number or a finite-clause marker. The paper revises the formemes used in the TectoMT English-Czech system to…
  11. Hidden Markov Tree Model in Dependency-based Machine Translation (2009)
    The paper applies Hidden Markov Tree Models (HMTM), a tree version of the hidden Markov chain, to the transfer step of a tree-based MT system.
