## Papers

The most cited first (OpenAlex and our library).

1. **[Coordination Structures in Dependency Treebanks](https://md.research.elamur.ai/free/en/papers/popel-2013-coordination-structures-dependency-treebanks/)** *(2013 · 65 citations)* A dependency tree cannot show the symmetric relation between conjuncts without a convention, so every treebank picks one.
2. **[Udapi: Universal API for Universal Dependencies](https://md.research.elamur.ai/free/en/papers/popel-2017-udapi-universal-api-universal-dependencies/)** *(2017 · 61 citations)* 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.
3. **[CorefUD 1.0: Coreference Meets Universal Dependencies](https://md.research.elamur.ai/free/en/papers/nedoluzhko-2022-corefud-1-0-coreference-meets/)** *(2022 · 48 citations)* 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. **[Cross-lingual Coreference Resolution of Pronouns](https://md.research.elamur.ai/free/en/papers/novak-2014-cross-lingual-coreference-resolution-pronouns/)** *(2014 · 31 citations)* Novák and Žabokrtský study coreference resolution (CR) on a bitext. Their goal is to resolve English 3rd-person central pronouns (personal, possessive and reflexive) more accurately by drawing on the aligned Czech translation. The two languages handle pronouns differently. Czech has grammatical gender, drops subject…
5. **[Hidden Markov Tree Model in Dependency-based Machine Translation](https://md.research.elamur.ai/free/en/papers/zabokrtsky-2009-hidden-markov-tree-model-dependency/)** *(2009 · 30 citations)* 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.
6. **[Translation of "It" in a Deep Syntax Framework](https://md.research.elamur.ai/free/en/papers/novak-2013-translation-it-deep-syntax-framework/)** *(2013 · 29 citations)* English "it" has no single Czech counterpart. It may be a personal pronoun or zero anaphor, a neuter demonstrative "to", or nothing at all in a cleft or pleonastic construction. The paper builds a discriminative classifier for these three classes inside the TectoMT deep-syntax system. The training data is the Prague…
7. **[Formemes in English-Czech Deep Syntactic MT](https://md.research.elamur.ai/free/en/papers/dusek-2012-formemes-english-czech-deep-syntactic/)** *(2012 · 28 citations)* 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…
8. **[Findings of the Second Shared Task on Multilingual Coreference Resolution](https://md.research.elamur.ai/free/en/papers/zabokrtsky-2023-findings-second-shared-task-multilingual/)** *(2023 · 27 citations)* This paper describes the second round of the multilingual coreference resolution shared task, held with CRAC 2023.
9. **[Arabic Syntactic Trees: from Constituency to Dependency](https://md.research.elamur.ai/free/en/papers/zabokrtsky-2003-arabic-syntactic-trees-constituency-dependency/)** *(2003 · 26 citations)* The note reports work in progress on converting Penn-style phrase-structure trees of Arabic (from the LDC Arabic Treebank) into the analytical dependency trees of the Prague school.
10. **[Comparison of Classification and Ranking Approaches to Pronominal Anaphora Resolution in Czech](https://md.research.elamur.ai/free/en/papers/ngy-2009-comparison-classification-ranking-approaches-pronominal/)** *(2009 · 16 citations)* The paper addresses resolving third-person personal and possessive pronouns in Czech, including zero (pro-dropped) pronouns that are reconstructed in the deep-syntactic layer.
11. **[Projection-based Coreference Resolution Using Deep Syntax](https://md.research.elamur.ai/free/en/papers/novak-2017-projection-based-coreference-resolution-deep/)** *(2017 · 14 citations)* The paper addresses coreference resolution for German and Russian when no coreference-annotated data exist in those languages.
12. **[Coreference meets Universal Dependencies – a pilot experiment on harmonizing coreference datasets for 11 languages](https://md.research.elamur.ai/free/en/papers/nedoluzhko-2021-coreference-meets-universal-dependencies/)** *(2021 · 11 citations)* The report converts 17 existing coreference datasets for 11 languages into one scheme based on Universal Dependencies.
13. **[Findings of the Fourth Shared Task on Multilingual Coreference Resolution: Can LLMs Dethrone Traditional Approaches?](https://md.research.elamur.ai/free/en/papers/novak-2025-findings-fourth-shared-task-multilingual/)** *(2025 · 10 citations)* 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…
14. **[Findings of the Fifth Shared Task on Multilingual Coreference Resolution: Expanding Datasets for Long-Range Entities](https://md.research.elamur.ai/free/en/papers/novak-2026-findings-fifth-shared-task-multilingual/)** *(2026 · 6 citations)* The fifth edition of the multilingual coreference shared task, held with CODI-CRAC 2026, again asked for mention detection and identity coreference clustering.
15. **[Towards Universal Segmentations: UniSegments 1.0](https://md.research.elamur.ai/free/en/papers/zabokrtsky-2022-universal-segmentations-unisegments-1-0/)** *(2022 · 6 citations)* Plenty of annotated data already exists for morphological segmentation, that is, dividing a word form into morphs.
16. **[A Machine Learning Approach to Automatic Functor Assignment in the Prague Dependency Treebank](https://md.research.elamur.ai/free/en/papers/zabokrtsky-2002-machine-learning-approach-automatic-functor/)** *(2002 · 4 citations)* Converting analytical tree structures (ATS) into tectogrammatical tree structures (TGTS) in the Prague Dependency Treebank (PDT) requires a great deal of manual work by expert linguists.
17. **[Do UD Trees Match Mention Spans in Coreference Annotations?](https://md.research.elamur.ai/free/en/papers/popel-2021-do-ud-trees-match-mention/)** *(2021 · 3 citations)* 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…
