What we deliver — and exactly how

Format specs, quality thresholds, language coverage and delivery details for every AI data service. Built for teams who need to pass this to an engineering or procurement lead.

Output formats

We deliver in your format

Default delivery is JSONL — one record per line, Hugging Face-ready. We also produce Label Studio JSON, SRT/VTT for audio, and custom CSV or TSV on request.

DEFAULT

JSONL

One annotation record per line. Compatible with Hugging Face datasets, OpenAI fine-tuning and most ML pipelines out of the box.

{"id": "ax-001",
 "text": "שלום, אני צריך עזרה",
 "lang": "he",
 "dialect": "modern",
 "label": "support_request",
 "confidence": 0.97,
 "annotator": "native_he_001",
 "reviewed": true}

RLHF Preference Pairs

Structured for DPO / PPO training. Each record contains a prompt, chosen response and rejected response with annotator rationale.

{"id": "ax-rlhf-044",
 "prompt": "اشرح البرمجة للمبتدئين",
 "chosen": "البرمجة هي ...",
 "rejected": "برمجة = كود ...",
 "lang": "ar", "dialect": "msa",
 "rationale": "chosen: clearer, formal",
 "iaa_score": 0.88}

Audio / Speech

WAV + JSONL metadata. Audio segmented by utterance, with speaker tag, dialect label, start/end timestamps and transcription.

{"id": "ax-audio-017",
 "file": "ax-017.wav",
 "start_ms": 0, "end_ms": 3200,
 "speaker": "F_AR_EG_02",
 "dialect": "eg",
 "text": "عايز أعرف إمتى ...",
 "code_switch": false,
 "snr_db": 42.1}

HTR / OCR

Image + ground-truth text pairs. PNG/JPEG image of the handwritten or printed region, with UTF-8 transcription and bounding-box coordinates.

{"id": "ax-htr-209",
 "image": "page_04_line_03.png",
 "text": "ירושלים עיר הקודש",
 "script": "hebrew_print",
 "bbox": [12, 44, 320, 72],
 "confidence": 0.94,
 "era": "modern"}
Custom schemas If your pipeline uses a different schema, send us a sample record and we will adapt the delivery format before the pilot starts — at no extra charge.

Language coverage

Seven dialect tiers — one vendor

Most vendors cover Modern Standard Arabic. We cover the dialects your users actually speak — and Hebrew, which almost no Arabic-focused vendor touches.

Language / Dialect Code Speaker pool Tasks available Notes
Modern Hebrew he-IL ✓ Active All Primary market — including code-switch with English
Egyptian Arabic ar-EG ✓ Active All Largest dialect speaker base in our pool
Levantine Arabic ar-LEV ✓ Active Annotation · Audio · LLM eval Syria · Lebanon · Jordan · Palestine
Gulf Arabic ar-XG ✓ Active Annotation · Audio Saudi Arabia · UAE · Kuwait · Bahrain
Modern Standard Arabic ar-MSA ✓ Active All Used for formal, news and educational content
Moroccan Arabic (Darija) ar-MA ⬤ Limited Annotation · Audio Requires scoping call — longer lead time
Hebrew–Arabic Code-Switch he+ar ⬤ Specialist Audio · LLM eval Rare combination; dedicated pool of bilingual speakers

Quality & inter-annotator agreement

We measure quality before you do

Every delivery includes a QA report. Batches that do not reach our IAA threshold are re-annotated internally — you never receive a batch below the agreed bar.

≥ 0.80 Cohen's κ

Minimum inter-annotator agreement for binary and multi-class tasks. We use Cohen's Kappa for two annotators comparing a single categorical label.

≥ 0.75 Krippendorff's α

Used for ordinal, interval and multi-annotator tasks — including RLHF rating scales. Tolerates missing data and scales to more than two annotators.

10% QA sample

At least 10% of every batch is re-annotated by a senior reviewer before delivery. For pilots, this rises to 25%.

98% Acceptance rate

First-pass acceptance rate across active projects. Measured as batches delivered without a client-requested re-do.

QA workflow — every batch

  1. Annotator 1

    Primary annotation against task guidelines

  2. Annotator 2

    Independent second pass — no visibility of A1

  3. IAA check

    Automated disagreement flagging. Items below κ = 0.6 go to adjudication

  4. Adjudication

    Senior linguist resolves conflicts and documents the decision rationale

  5. QA sample

    10–25% blind re-annotation by a separate QA reviewer

  6. Delivery + report

    JSONL batch + QA metrics PDF sent together

Task taxonomy

What we annotate

NER

Named Entity Recognition

Person, organisation, location, date, product — in Hebrew and all Arabic dialects. Supports nested and overlapping spans.

SENT

Sentiment & Tone

Positive / Negative / Neutral at sentence or document level. Extended schemes include intensity (1–5) and specific emotions.

RLHF

RLHF Preference Pairs

Two model responses ranked by a native speaker. Includes a rationale field. Used for DPO, PPO and Constitutional AI pipelines.

CLASS

Intent & Topic Classification

Single or multi-label. Taxonomies provided by you or built jointly. Calibration set included in every pilot.

AUDIO

Speech Transcription

Verbatim or clean-read. Speaker diarisation, dialect labelling, code-switch flagging and confidence scores included.

HTR

Handwriting Transcription

Hebrew historical and modern scripts. Bounding boxes at line or word level. Ground-truth text in NFD-normalised UTF-8.

SAFE

Safety & Red-Teaming

Harmful content detection, cultural sensitivity checks and adversarial prompt evaluation in Hebrew and Arabic.

AUDIO-COLLECT

Speech Data Collection

Scripted and spontaneous recordings. Controlled dialect, age, gender distribution. WAV 16kHz 16-bit, noise screened.

Delivery & SLAs

Timelines you can plan around

48 hrs

Scoping call

Response to first contact. We schedule a 30-min call within two business days.

72 hrs

Pilot proposal

After the scoping call — fixed price, scope, IAA target and acceptance criteria.

1–2 wks

Pilot launch

From signed agreement to first annotated items. Includes annotator briefing and calibration set.

2–4 wks

Pilot delivery

Typical 100–500 item pilot. Delivered with full QA report and IAA breakdown.

Weekly

Volume batches

Once at volume — batches delivered weekly with rolling QA metrics. Daily for urgent projects.

5 biz days

Re-annotation SLA

If a delivered batch fails your QA, we re-annotate flagged items within five business days at no charge.
