| # Italian-Common-Corpus |
|
|
| The Italian dataset with the highest density of useful information per token. Built by [ModotAI](https://things-ai.org) for training Italian language models. |
|
|
| ## Subsets |
|
|
| | Subset | File | Documents | Words | Description | |
| |--------|------|-----------|-------|-------------| |
| | **Web Crawl** | `icc-web.parquet` | ~27K | ~17M | Italian sources: news, tech, science, culture, law, food, sport | |
| | **Wikipedia IT** | `wiki-it-clean.parquet` | ~1.35M | ~698M | Cleaned Italian Wikipedia — removed Notes, Bibliography, Voci correlate, stub articles | |
|
|
| **Total: 1,377,369 documents, 715,313,213 words (~929M tokens)** |
|
|
| ## Usage |
|
|
| ```python |
| from datasets import load_dataset |
| |
| # Load web crawl subset |
| icc = load_dataset("ThingsAI/Italian-Common-Corpus", data_files="data/icc-web.parquet", split="train") |
| |
| # Load Wikipedia subset |
| wiki = load_dataset("ThingsAI/Italian-Common-Corpus", data_files="data/wiki-it-clean.parquet", split="train") |
| |
| # Load everything |
| full = load_dataset("ThingsAI/Italian-Common-Corpus", split="train") |
| |
| print(icc[0]) |
| ``` |
|
|
|
|
| ## Quality Pipeline |
|
|
| 1. **Async crawling** — 20 parallel workers, rate-limited per domain |
| 2. **Text extraction** — Trafilatura with precision mode |
| 3. **Spam detection** — 13 regex patterns + statistical analysis |
| 4. **Quality scoring** — Lexical richness, sentence structure, punctuation (0-100) |
| 5. **Deduplication** — MD5 hash + partial content matching |
| 6. **Wikipedia cleaning** — Section removal (Notes, Bibliography, See also, External links) |
|
|
| Only documents scoring ≥50/100 are included. |
