DIACR-Ita dataset

The DIACR-Ita dataset comprehends the test set used for the DIACR-Ita shared task (https://diacr-ita.github.io/DIACR-Ita/), organised as part of Evalita 2020 evaluation campaign (http://www.evalita.it/2020). The task challenged participants to develop systems that can automatically detect if a given word has changed its meaning over time, given contextual information from corpora.<p>For the test phase, the following data were provided:<p>1- a diachronic split of the “L’Unita`” corpus into the two sub-corpora, C1 and C2, each belonging to a specific time period (respectively, 1945 − 1970 and 1990 − 2014);<p>2- 18 target words, among which 6 were identified as target of semantic meaning change between the two time periods.<p>The present item refers to the 18 target words and their gold labels.<p>
