# Dataset Card for Kurdish Web Corpus (Deduplicated)

## Dataset Summary

A multilingual corpus of web text in three Kurdish/Zaza varieties — Kurmanji Kurdish
(`kmr_Latn`), Sorani Kurdish (`ckb_Arab`), and Zazaki (`diq_Latn`) — scraped from Kurdish-language
websites, language-identified with [GlotLID](https://github.com/cisnlp/GlotLID), and
deduplicated (exact + MinHash near-duplicate removal). See the "Dataset Creation" section below
for the full pipeline.

Rows, by language config:

| config      | language          | script | rows    | publishers |
|-------------|-------------------|--------|---------|------------|
| `kmr_Latn`  | Kurmanji Kurdish  | Latin  | 517,335 | 51         |
| `ckb_Arab`  | Sorani Kurdish    | Arabic | 158,266 | 15         |
| `diq_Latn`  | Zazaki            | Latin  | 319     | 12         |

## Supported Tasks

Intended as pretraining/fine-tuning text for causal or masked language modeling in
under-resourced Kurdish and Zaza varieties. No task-specific labels are provided.

## Languages

- `kmr` — Kurmanji (Northern Kurdish), Latin script
- `ckb` — Sorani (Central Kurdish), Arabic script
- `diq` — Zazaki (Dimli), Latin script

Language and `lang_score` were assigned by GlotLID at scrape time (see
[kurdish_scrapy](https://github.com/cikay/kurdish_scrapy)) and are carried through unchanged;
they are not re-verified by the dedup pipeline.

## Dataset Structure

### Data Instances

```json
{
  "url": "https://example.com/page-slug",
  "text": "Full page text ...",
  "lang": "kmr_Latn",
  "lang_score": 0.98,
  "publish_date": "2024-01-01",
  "publisher": "example.com",
  "title": "Page title",
  "word_count": 342
}
```

### Data Fields

- `url` (`string`): the page's source URL; doubles as a unique document ID.
- `text` (`string`): full page text, NFC-normalized.
- `lang` (`string`): GlotLID language/script code, one of `kmr_Latn`, `ckb_Arab`, `diq_Latn`.
- `lang_score` (`float32`): GlotLID confidence score for `lang`.
- `publish_date` (`string`, nullable): publication/posting date as recorded by the source site.
- `publisher` (`string`): source site's domain.
- `title` (`string`): page title.
- `word_count` (`int32`): whitespace-split word count of `text`, computed from the final
  deduplicated text (not carried over from the source).

### Data Splits

There is no train/dev/test split. Instead, the split name is a crawl snapshot date: it states
that all data was collected up to and including that date. For example, a split named
`2026_6_27` means the crawl covers everything gathered through June 27, 2026.

A `_part` suffix (e.g. `2026_6_27_part`) means the crawl was interrupted before it finished —
it did **not** manage to collect all data through that date, so treat it as a partial/incomplete
snapshot rather than a clean cutoff. Later, complete uploads may supersede an earlier `_part`
snapshot for the same or a later date.

Row counts for the current snapshot:

| config      | rows    |
|-------------|---------|
| `kmr_Latn`  | 517,335 |
| `ckb_Arab`  | 158,266 |
| `diq_Latn`  | 319     |

## Dataset Creation

### Source Data

Pages were scraped from Kurdish-language websites with
[kurdish_scrapy](https://github.com/cikay/kurdish_scrapy), with page text extracted via
[trafilatura](https://github.com/adbar/trafilatura) and language-identified with GlotLID at
scrape time. Exact- and near-duplicate removal was then run with
[dedup](https://github.com/cikay/dedup) (this repo).
