# IATE 2016 — Inter-Active Terminology for Europe

Tidy HuggingFace release of the **IATE** terminology export dump from **2016-04-25** (the snapshot in `iate.zip`). IATE is the official multilingual terminology database of the EU institutions and bodies — see <https://iate.europa.eu>, <https://iate.europa.eu/faq>, and <https://iate.europa.eu/download-iate>.

This is the **2016 snapshot only**. IATE is continuously updated; for the latest dump pull from the official IATE download page.

Mirror of the raw upstream zip: [`alvations/stash · iate/iate.zip`](https://huggingface.co/datasets/alvations/stash/tree/main/iate).

## Configs

| Config        | Rows       | Schema | Notes |
| ------------- | ---------: | ------ | ----- |
| `monolingual` | 6,148,883  | one row per `(term_id, lang)` entry | full multilingual TSV; spans all EU official languages (~24) |
| `en-de`       |   546,974  | one row per aligned EN ↔ DE term pair | pre-aligned bilingual subset |
| `en-fr`       |   730,779  | one row per aligned EN ↔ FR term pair | pre-aligned bilingual subset |
| `en-fi`       |   226,688  | one row per aligned EN ↔ FI term pair | pre-aligned bilingual subset |
| `en-cs`       |    13,524  | one row per aligned EN ↔ CS term pair | pre-aligned bilingual subset |

The upstream zip also contained `iate_en-ru.csv` / `.json` but they were empty (header only) — skipped.

## Usage

```python
from datasets import load_dataset

# Full multilingual dump
mono = load_dataset("alvations/iate-2016", "monolingual", split="train")
print(mono[0])
# {'term_id': 'IATE-14', 'lang': 'ro', 'term': 'Agenție de aprovizionare',
#  'term_type': 'fullForm', 'reliability': 3}

# Pre-aligned bilingual subsets (great as MT terminology gazetteers)
en_de = load_dataset("alvations/iate-2016", "en-de", split="train")
print(en_de[0])
# {'term_id': 'IATE-84',
#  'src_lang': 'en', 'src_term': 'competence of the Member States',
#  'tgt_lang': 'de', 'tgt_term': 'Zuständigkeit der Mitgliedstaaten'}

# Recover all language entries for a single term
mono_df = mono.to_pandas()
mono_df[mono_df["term_id"] == "IATE-84"]
# 23 rows — one per EU official language
```

## Schemas

### `monolingual`

| Column        | Type   | Description |
| ------------- | ------ | ----------- |
| `term_id`     | string | IATE entry id, e.g. `"IATE-14"` |
| `lang`        | string | ISO-639-1 code (`en`, `de`, `fr`, `bg`, `el`, …) |
| `term`        | string | the term text in that language |
| `term_type`   | string | upstream type label: most commonly `fullForm` (the canonical form); sometimes abbreviation / short-form variants |
| `reliability` | int8   | reliability code, 1–5 (see "Reliability codes" below) |

### `en-{de,fr,fi,cs}`

| Column      | Type   | Description |
| ----------- | ------ | ----------- |
| `term_id`   | string | IATE entry id (same one shared across languages) |
| `src_lang`  | string | always `"en"` |
| `src_term`  | string | English term |
| `tgt_lang`  | string | `"de"` / `"fr"` / `"fi"` / `"cs"` |
| `tgt_term`  | string | target-language term |

The 4 bilingual configs share one schema, so you can `concatenate_datasets([...])` them with a single column projection.

## Reliability codes (IATE convention)

| Code | Meaning |
| ---: | ------- |
| 1    | Not verified |
| 2    | Minimum reliability |
| 3    | Reliable (terminologist-checked) |
| 4    | Very reliable |
| 5    | Verified / institutional gold standard |

Most rows in this snapshot carry code `3` (reliable).

## Provenance

- Upstream zip: `iate.zip` containing 12 files (1 monolingual TSV, 4 bilingual `.csv`/`.json` pairs for EN-DE/FR/FI/CS, plus empty EN-RU); 564 MB uncompressed, snapshot 2016-04-25.
- Mirror: <https://huggingface.co/datasets/alvations/stash/tree/main/iate>
- Conversion: stream-build via `zipfile` + pyarrow `ParquetWriter` (no on-disk extraction). The 321 MB master CSV is written in 200K-row batches.
- Build script: `build.py` alongside this README.
