WG1 Tasks: Task 1.2 on MWE annotation guidelines and UD-PARSEME unification

Abstract:

Within UniDive, Task 2.2 (Design of a lexicon-corpus interface) of WG2 involves the development and upgrade of the ELEXIS-WSD Parallel Sense-Annotated Corpus (ELEXIS-WSD for short), a small-scale parallel corpus consisting of language subcorpora containing translations of the same sentences in multiple languages; with manual tokenization, lemmatization, morphosyntactic tagging, and, most importantly, manually assigned sense annotations from a lexicographic or lexical resource (such as monolingual dictionaries or wordnets), directly linking the corpus to the lexicon. ELEXIS-WSD is a useful resource for word-sense disambiguation tasks and cross-lingual comparisons. The latest version before the introduction of UniDive was 1.1, with subcorpora for 10 languages: Bulgarian, Danish, Dutch, English, Estonian, Hungarian, Italian, Portuguese, Slovene and Spanish.

In this paper, we present the results of the activities of Task 2.2 of UniDive, which culminated in the publication of version 2.0 of ELEXIS-WSD in April 2026. The main goals included (1) the introduction of new languages to the corpus; (2) the addition of new annotation layers.
