# Dataset Card for I.PHI
<!-- Provide a quick summary of the dataset. -->
This is the I.PHI dataset from the Nature article *"[Restoring and attributing ancient texts using deep neural networks](https://www.nature.com/articles/s41586-022-04448-z)"*.
I.PHI contains geographical and chronological metadata for a cleaned subset of the [Packard Humanities Institute](https://inscriptions.packhum.org/) database of ancient Greek inscriptions.
## Dataset Details
### Dataset Description
<!-- Provide a longer summary of what this dataset is. -->
- **Curated by:** Thea Sommerschield\*, Yannis Assael\*, Brendan Shillingford, Mahyar Bordbar, John Pavlopoulos, Marita Chatzipanagiotou, Ion Androutsopoulos, Jonathan Prag, Nando de Freitas
- **Shared by:** George Baker
- **Language(s) (NLP):** Ancient and Byzantine Greek
- **License:** Apache 2.0
### Dataset Sources
<!-- Provide the basic links for the dataset. -->
- **Repository:** [github.com/sommerschield/iphi](https://github.com/sommerschield/iphi)
- **Paper:** [Restoring and attributing ancient texts using deep neural networks](https://www.nature.com/articles/s41586-022-04448-z)
## Uses
<!-- Address questions around how the dataset is intended to be used. -->
I.PHI contains data for chronological attribution (dating), geographical attribution, and text restoration of Ancient and Byzantine Greek inscriptions.
#### Data Collection and Processing
Duplicate inscriptions and inscriptions with fewer than 50 characters are dropped.
Note: this version contains slightly more examples than the number reported in the original article (70,682/8,751/8,769 instead of 63,014/7,783/7,811). This is likely due to additions to the [Packard Humanities Institute](https://inscriptions.packhum.org/) database from which the dataset is sourced.
## Citation
<!-- If there is a paper or blog post introducing the dataset, the APA and Bibtex information for that should go in this section. -->
