# Data |
|
|
|
We trained the models on available annotated corpora in Ancient Greek. |
|
There are only two sizeable annotated datasets in Ancient Greek, which are currently un- der release: the first one by Berti 2023, |
|
consists of a fully annotated text of Athenaeus’ Deipnosophists, developed in the context of the Digital Athenaeus project. |
|
The second one by Foka et al. 2020, is a fully annotated text of Pausanias’ Periegesis Hellados, developed in the context of the |
|
Digital Periegesis project. In addition, we used smaller corpora annotated by students and scholars on Recogito: |
|
the Odyssey annotated by Kemp 2021; a mixed corpus including excerpts from the Library attributed to Apollodorus and from Strabo’s Geography, |
|
annotated by Chiara Palladino; Book 1 of Xenophon’s Anabasis, created by Thomas Visser; and Demos- thenes’ Against Neaira, |
|
created by Rachel Milio. |
