DIACU: A dataset for the DIAchronic analysis of Church Slavonic

The Church Slavonic language has evolved over time without being formalized into a precise grammar.Therefore, there is currently no clearly outlined history of this language tracing its evolution.However, in recent years, there has been a greater effort to digitize these resources, partly motivated by increased sensitivity with respect to the need to preserve multilingual knowledge.To exploit them, we propose DIACU (DIAchronic Analysis of Church Slavonic), a comprehensive collection of several existing corpora in Church Slavonic.In this work, we thoroughly describe the collection of this novel dataset and test its effectiveness as a training set for attributing Slavonic texts to specific periods.The dataset and the code of the experiments are available at https: //github.com/MariaCassese/DIACU.
