# 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"` |
## File layout
- `en_00000.parquet` … `en_00222.parquet` — 223 English shards
- `ar_00000.parquet` … `ar_00178.parquet` — 179 Arabic shards
Each file is zstd-compressed parquet.
