| # DeepLatent bilingual tokenizer-data |
|
|
| Balanced English/Arabic corpus for tokenizer training. The two languages carry |
| essentially the same number of Unicode codepoints, so a BPE/WordPiece |
| tokenizer trained on this corpus sees equal representation of both languages |
| by character content. |
|
|
| ## Composition |
|
|
| | Slice | Source | Filter | Rows | Chars | |
| |----------|-----------------------------------------------------------------------------------------|----------------------------------------------------|-------------|--------------------| |
| | English | [`almaghrabima/deeplatent-hq-merged-dedup-token-counts`](https://huggingface.co/datasets/almaghrabima/deeplatent-hq-merged-dedup-token-counts) | GlotLID `language == "English"` | 3,980,035 | 12,377,830,142 | |
| | Arabic | [`AdaMLLab/AraMix-HQ`](https://huggingface.co/datasets/AdaMLLab/AraMix-HQ) | `mmbert_score >= 0.2784` ∧ `language != "English"` | 2,380,570 | 12,380,271,596 | |
| | **Total**| | | **6,360,605** | **24,758,101,738** | |
|
|
| The Arabic threshold `mmbert_score >= 0.2784` was chosen so the Arabic char |
| count matches the English char count (balancing the two languages). This |
| yields the top ~7% highest-scoring Arabic content in AraMix-HQ. |
|
|
| Language labels come from GlotLID (`cis-lmu/glotlid`) run on the first 2000 |
| characters of each document. The HQ corpus is fully labeled; the AraMix-HQ |
| source was partially labeled (~38.5% of shards) — remaining Arabic rows in |
| this merged release default to `"Arabic"` since labeled AraMix-HQ shards were |
| 96.4% Arabic. |
|
|
| ## Schema |
|
|
| | Column | Type | Description | |
| |-----------|--------|-----------------------------------------------------------------| |
| | `text` | string | Document text | |
| | `source` | string | Original sub-source (e.g. `ar`, `en`, `lightonai/ArabicWeb24`) | |
| | `language`| string | GlotLID label: `"English"`, `"Arabic"`, or raw `lang_Script` | |
| | `origin` | string | `"hq"` or `"aramix"` | |
