## Annotation layers

| Layer | Origin |
| --- | --- |
| Lemmas | converted with corrections |
| UPOS | converted with corrections |
| XPOS | automatic |
| Features | converted with corrections |
| Relations | manual native |

UD scale: *manual native* — annotated by hand directly in UD; *converted from manual* — converted from manual annotation in another scheme; *converted with corrections* — converted and partly corrected by hand; *automatic with corrections* — automatic, with partial manual corrections; *automatic* — automatic; *not available* — the layer is absent.

## Size

| Split | Sentences | Tokens | Words | Multiword tokens | Empty nodes |
| --- | --- | --- | --- | --- | --- |
| train | 2 774 | 95 302 | 97 666 | 2 340 | 228 |
| dev | 308 | 11 940 | 12 218 | 278 | 45 |

| **total** | 3 419 | 119 060 | 122 024 | 2 936 | 306 |

Tokens are surface tokens (Spanish `vámonos` is one), words are syntactic words (`vamos` + `nos`); multiword tokens are those split into several words; empty nodes are the `N.M` nodes of the enhanced graph.

## Summary

> Italian-Old is a treebank containing **Dante Alighieri's Comedy** (composed between approximately 1306 and 1321), based on the 1994 Petrocchi edition and taken from the [**DanteSearch corpus**](https://dantesearch.dantenetwork.it), originally created at the University of Pisa, Italy. It is a treebank of Old Italian, specifically Florentine.

## Introduction

> This treebank includes 3 419 sentences (122 038 syntactic words) and is a literary text (poetry). It is divided into three sections, known as Cantiche: Inferno, Purgatorio, and Paradiso. Specifically, Inferno includes 1 228 sentences and 41 368 syntactic words; Purgatorio consists of 1 174 sentences and 41 277 syntactic words; while Paradiso contains 1 017 sentences and 39 393 syntactic words.
> 
> The treebank is split into three subsets, `dev`, `test` and `train`, with approximate ratios of 10%, 10%, and 80%, respectively, for Inferno, Purgatorio, and Paradiso. These subsets are then merged into unique `dev`, `test` and `train` sets.
> 
> The distribution of Inferno (tokens: 41 368) with respect to the subsets is as follows:
> 
> - `train`: 1002 sentences (OldItalian_Dante_Inferno-1; OldItalian_Dante_Inferno-1002) - 33104 tokens
> - `dev`: 107 sentences (OldItalian_Dante_Inferno-1003; OldItalian_Dante_Inferno-1109) - 4136 tokens
> - `test`: 119 sentences (OldItalian_Dante_Inferno-1110; OldItalian_Dante_Inferno-1228) - 4128 tokens
> 
> The distribution of Purgatorio (tokens: 41 277) with respect to the subsets is as follows:
> 
> - `train`: 958 sentences (OldItalian_Dante_Purgatorio-1; OldItalian_Dante_Purgatorio-958) - 33031 tokens
> - `dev`: 100 sentences (OldItalian_Dante_Purgatorio-959; OldItalian_Dante_Purgatorio-1058) - 4130 tokens
> - `test`: 116 sentences (OldItalian_Dante_Purgatorio-1059; OldItalian_Dante_Purgatorio-1174) - 4116 tokens
> 
> The distribution of Paradiso (tokens: 39 393) with respect to the subsets is as follows:
> 
> - `train`: 814 sentences (OldItalian_Dante_Paradiso-1; OldItalian_Dante_Paradiso-814) - 31546 tokens
> - `dev`: 101 sentences (OldItalian_Dante_Paradiso-815; OldItalian_Dante_Paradiso-915) - 3951 tokens
> - `test`: 102 sentences (OldItalian_Dante_Paradiso-916; OldItalian_Dante_Paradiso-1017) - 3896 tokens
> 
> The treebank also includes enhanced dependencies annotation, with a specific focus on the `orphan` dependency relation. For the criteria adopted in the enhanced annotation, please refer to the paper "«Are you Afraid of Ghosts?» A Proposal for Busting Predicate Ellipsis in Universal Dependencies" (Corbetta et al., 2025).

> **!! Italian-Old treebank is still under revision to check for mistakes and inconsistencies throughout the annotation of the Cantiche; therefore, its structure is subject to change. If you use the resource and find any problems, please do not hesitate to contact the author to suggest a correction or improvement.**
