# Mouseion: open data for a connected Greek and Latin library

This dataset powers the [Mouseion library](https://huggingface.co/spaces/michaelkimmel/mouseion-library), a project hosted by Polis – The Jerusalem Institute of Languages and Humanities. Every file is plain JSON and can be reused directly.

## Contents

| Path | What it holds |
| --- | --- |
| `catalog.json` | Works, editions, translations, citation style, statistics |
| `text/{work}/{book}.json` | Every word with lemma and grammar code, English translation by section, phrases, links to dictionaries and quotations, manuscript variants (Iliad) |
| `lines/{work}.json` | Plain text of each citable unit |
| `lemmas.json`, `tags.json` | Dictionary forms with short glosses and counts; 9-character grammar codes (Perseus treebank scheme) |
| `index/{lang}/{n}.json` | Where each dictionary form occurs (work, book, unit, token, grammar) |
| `forms/{lang}.json` | Accent-free spelling → dictionary forms |
| `dict/{n}.json` | LSJ and Lewis & Short entries and attested forms |
| `phrases.json` | Phrase dictionary sample and automatically mined formulae with occurrences |
| `scholia/{book}.json` | Venetus A scholia on the Iliad, linked to lines, with sample English drafts |

Book files also carry `notes` (footnotes of the printed edition), `noterefs` and `notecited` (passages those notes cite, linked both ways). Works marked `hidden` in the catalog are duplicate copies of another work.

## How it was made

- Texts and translations: Perseus Digital Library and Open Greek and Latin (First Thousand Years of Greek), CC BY-SA.
- Lemmas and grammar: Ancient Greek Dependency Treebank (human-checked) for Homer, Hesiod, Aeschylus and five plays of Sophocles; LatinCy and a Greek spaCy model elsewhere (automatic, marked as such).
- Dictionaries: LSJ and Lewis & Short from the Perseus lexica, CC BY-SA.
- Venetus A text, images and scholia: Homer Multitext project, Creative Commons.
- Editors' notes: footnotes and apparatus of the printed editions, with their citations resolved using the abbreviations of LSJ and Lewis & Short.
- Quotations: shared five-word sequences between earlier and later authors, found automatically.
- AI translations: a few demonstration drafts, labelled and unreviewed.
