logical-transcripts

Golden paired dataset for training models to transliterate Arabic Latin text into scholarly diacritized form — built from a single recorded Islamic lecture (Chapter 24, Lecture 16) with a raw ASR transcript and a human-polished scholarly transcript.

Two artifacts are stored separately for provenance and review:

File	Rows	Purpose
`train.jsonl`	203	Golden — quality-filtered pairs for training
`bronze.jsonl`	773	Bronze — every aligned sentence pair before filtering, tagged with `category` + `diacritics` count for provenance/review

Golden quality criteria

Rows in train.jsonl meet both:

input != output (no identity rows)
Output contains ≥ 2 distinct diacritized letters — each diacritic-carrying base letter counts once (ā, ḥ, ṣ, …), plus the ʿ / ʾ hamza-ʿayn spacing modifier letters.

Markdown asterisks from the source transcript are stripped from outputs.

Schema

{
  "instruction": "Transliterate the following Arabic Latin text to scholarly diacritized form:",
  "input": "There was no athan.",
  "output": "There was no aẓān."
}

The instruction/input/output schema follows the standard instruction-tuning convention, so it can be concatenated with other transliteration datasets for training.

Task

The input is raw, un-diacritized Arabic-as-spoken-in-Latin-script (including ASR artifacts: stutters, mis-heard words, run-on sentences). The output is the scholarly diacritized transliteration (macrons, sub-dots, hamza/ʿayn, word corrections, cleaned punctuation). Rows therefore train diacritization + ASR correction jointly — a broader task than a clean-input transliteration baseline.

Statistics

203 golden rows, 773 bronze rows
Golden input length: median 90 chars, max 1737
Diacritic-letter distribution: 2×85, 3×53, 4×22, 5×23, 6×8, 7×9, 8×3

Provenance

Source material: 8 {input_text, output_text} chunk pairs extracted from a single recorded Islamic lecture (Chapter 24, Lecture 16). The concatenated inputs exactly reconstruct the raw ASR transcript; the concatenated outputs exactly reconstruct the polished scholarly transcript. Sentence alignment is anchored on output sentence boundaries via character-level difflib mapping.
