| # Bloomberg_Financial_News_processed |
| |
| ## Source |
| - Original dataset: `danidanou/Bloomberg_Financial_News` |
| - Original dataset page: https://huggingface.co/datasets/danidanou/Bloomberg_Financial_News |
| - Split: `train` |
| - Config/subset: `(default)` |
| |
| ## Processing |
| - Streamed row-by-row with Hugging Face `datasets` (`streaming=True`). |
| - Text field extracted by priority from `--text-fields` (case-insensitive). |
| - Newline normalization: `\r\n` / `\r` -> `\n`. |
| - Removed non-visible control/format characters (`Unicode Cc/Cf/Cs/Co/Cn`, except `\n\t\r`). |
| - Converted non-breaking spaces (`U+00A0`) to regular spaces. |
| - Applied lightweight mojibake recovery heuristic for common UTF-8/cp1252 artifacts. |
| - Whitespace normalized (`[ \t]+` -> single space, 3+ newlines -> double newline). |
| - Dropped rows with cleaned text length `< 50`. |
| - Output schema: `text`, `language`, `style_tag`, `metadata`. |
| - Output shard format: `jsonl.gz`. |
|
|
| ## Run Summary |
| - Last updated: 2026-04-25 06:45:12 UTC |
| - Seen rows: 446,762 |
| - Kept rows: 446,707 |
| - Dropped (no text): 0 |
| - Dropped (too short): 55 |
| - Changed rows: 433,182 |
| - Length stats (chars): min=50, mean=2708.876, max=73941 |
|
|
| ## Notes |
| - `metadata` preserves source row context/fields for traceability. |
| - Processing is resumable with checkpoint files. |
