# State Archives of Assyria — Morphosyntactic Letter Corpus

7,355 fully annotated sentences from **2,586 Neo-Assyrian letters** — the royal
correspondence of the Assyrian empire, 8th–7th century BCE.

Every sentence carries full morphosyntactic annotation (lemma, UPOS, morphological
features, dependency head and relation) **and** the letter's archival context: who wrote it,
who received it, which archive it was excavated from, and where.

Row 0 is Adda-hati writing to the king, from the Northwest Palace at Nimrud:

> `ana šarri bēlīya urdaka Adda-hati` — *"To the king, my lord: your servant Adda-hati."*

## Fields

- `tokens` — `{id, form, lemma, upos, xpos, feats, head, deprel}` (CoNLL-U)
- `text` — the normalised sentence
- `text_id` (ORACC/CDLI P-number), `sent_id`, `volume` (`saa01`–`saa21`), `sentence_idx`
- Letter metadata joined from the ORACC catalogue: `ancient_author`, `ancient_recipient`,
  `archive`, `collection`, `provenience`, `genre`, `dialect`, `language`, `period`, `ruler`,
  `script`, `object_type`, `material`, `museum_no`, `date_of_origin`, `designation`,
  `vol_title`, `primary_publication`

Covers 10 of the 21 SAA volumes. All 2,586 letters join to a catalogue record.

## Notes on the conversion

Two quirks of the deposit are handled here, and are worth knowing if you go back to the source:

- The deposit ships a `concatenated/` directory holding 10 per-volume merged files — **the
  same letters again**, in UD-release form. They are excluded; including them would double
  the corpus.
- The `*Renumbered` files open with a provenance pseudo-sentence (`saao / saa01 / P224395`,
  tokenised but unlemmatised). These are dropped — they are not sentences of the letters.

Filenames in the source are not uniform (`P<id>lookup`, `P<id>Renumbered`,
`P<id>lookupRenumbered`, `P<id>_lookup`, `P<id>_intermediate`, plus a few `X`/`Q` ids), so
text ids are extracted by pattern rather than by stripping suffixes.

## Caveats

- Akkadian is a **broken-text** tradition. Damaged/illegible signs appear as `x` runs in the
  text; they are preserved, not cleaned.
- Annotation quality descends from ORACC's lemmatisation; `xpos` and `feats` are sparse in
  some volumes.

## Load

```python
from datasets import load_dataset

ds = load_dataset("biglam/state-archives-assyria-letters", split="train")

# letters from one excavated archive, with their ancient sender
nimrud = ds.filter(lambda r: r["provenience"] and "Nimrud" in r["provenience"])
print(nimrud[0]["ancient_author"], "->", nimrud[0]["ancient_recipient"])
```
