Constructing a Lexical Resource of Russian Derivational Morphology

no code implementations LREC 2022 Lukáš Kyjánek, Olga Lyashevskaya, Anna Nedoluzhko, Daniil Vodolazsky, Zdeněk Žabokrtský

Therefore, we devote this paper to improving one of the methods of constructing such resources and to the application of the method to a Russian lexicon, which results in the creation of the largest lexical resource of Russian derivational relations.

Do UD Trees Match Mention Spans in Coreference Annotations?

no code implementations Findings (EMNLP) 2021 Martin Popel, Zdeněk Žabokrtský, Anna Nedoluzhko, Michal Novák, Daniel Zeman

One can find dozens of data resources for various languages in which coreference - a relation between two or more expressions that refer to the same real-world entity - is manually annotated.

Sentence Meaning Representations Across Languages: What Can We Learn from Existing Frameworks?

no code implementations CL (ACL) 2020 Zdeněk Žabokrtský, Daniel Zeman, Magda Ševčíková

This article gives an overview of how sentence meaning is represented in eleven deep-syntactic frameworks, ranging from those based on linguistic theories elaborated for decades to rather lightweight NLP-motivated approaches.
