This data collection contains the Latin test data for SemEval 2020 Task 1: Unsupervised Lexical Semantic Change Detection:
a Latin text corpus pair (`corpus1/lemma`, `corpus2/lemma`)
40 lemmas which have been annotated for their lexical semantic change between the two corpora (`targets.txt`)
the annotated binary change scores of the targets for subtask 1, and their annotated graded change scores for subtask 2 (`truth/`)
The corpus data have been automatically lemmatized and part-of-speech tagged, and have been partially corrected by hand. For homonyms, the lemmas are followed by the '\#' symbol and the number of the homonym according to the Lewis-Short dictionary of Latin when this number is greater than 1. For example, the lemma 'dico' corresponds to the first homonym in the Lewis-Short dictionary and 'dico\#2' corresponds to the second homonym, cf. Lewis-Short dictionary.

Besides the official lemma version of the corpora for SemEval-2020 Task 1 we also provide the raw token version (corpus1/token/, corpus2/token/). It contains the raw sentences in the same order as in the lemma version. Find more information on the data and SemEval-2020 Task 1 in the paper referenced below.
The creation of the data was supported by the CRETA center and the CLARIN-D grant funded by the German Ministry for Education and Research (BMBF).
