Build cleaner NLP datasets with a
Text Annotation Company you can trust

Ship high-accuracy text labels, taxonomies, and RLHF signals with scholar-grade QA, secure pipelines, and Abaka Forge workflows tuned for your model and domain.

When text annotation slips, model quality follows. A 2–3 week delay to fix guidelines, redo batches, or reconcile label drift can push your release window and inflate costs by 20–40% through rework. In production, inconsistent entities, intents, or policy labels show up as hallucinations, unsafe outputs, and brittle tool calling—issues that are hard to debug after training. If your dataset grows while your QA stays flat, you’ll see accuracy decay over time as edge cases accumulate and reviewers interpret rules differently.

Abaka AI helps your team operationalize text annotation at scale without sacrificing rigor. We combine vertically specialized annotators across 50+ countries with multi-layer QA, measured acceptance gates, and Abaka Forge to manage instructions, sampling, and adjudication. Whether you’re building NER corpora, intent/slot datasets, preference signals for instruction tuning, or evaluation sets, you get consistent guidelines, secure handling (SOC 2, ISO 27001, GDPR, CCPA), and throughput that matches your roadmap—without vendor lock-in or data resale.

The Text Annotation Company Bottleneck

01

Quality Decay

Text labels drift quietly: new edge cases arrive, reviewers interpret guidelines differently, and yesterday’s “good enough” becomes today’s model bug. Even a 1–2% consistency drop across NER spans or intent classes can ripple into retrieval, routing, and safety layers. Abaka mitigates decay with tight rubric design, calibration rounds, and adjudication workflows in Abaka Forge, plus controlled reviewer throughput (up to 500 files/day per annotator) to preserve attention and reduce fatigue-driven mistakes.

02

Volume Walls

Most teams hit a wall when annotation demand spikes—new locales, new product features, or a sudden push for instruction tuning. Hiring and training internally can take 6–10 weeks, and ramp quality often lags another sprint. Abaka provides elastic capacity through a global network of 1M+ specialized annotators across 50+ countries, so you can expand coverage quickly while keeping the same guideline, QA, and sampling system across every batch.

03

Compliance Friction

Text datasets frequently include sensitive business context—support logs, contracts, medical notes, or security incidents—so teams lose weeks negotiating controls, access, and provenance. Abaka runs segregated secure pipelines with strict NDAs and supports SOC 2, ISO 27001, GDPR, and CCPA-aligned operations. You maintain full IP provenance and exclusive ownership—your data is never repurposed or resold—reducing downstream legal and privacy risk while keeping delivery moving.

01

Named entity recognition with span-level consistency

Design entity taxonomies and annotate spans with strict boundary rules, nested entities, and normalization (aliases, canonical IDs). Abaka Forge supports reviewer calibration, adjudication queues, and gold-set sampling to keep 99% accuracy targets realistic at scale. Common outputs include JSONL, BIO/IOB2 tags, and CoNLL-style TSV for search, compliance, and LLM grounding workflows.

02

Intent and slot labeling for assistants and routing

Label intent classes, slots, and dialogue states for customer support, banking, retail, and enterprise copilots. We help you define a stable label set, manage long-tail intents, and implement confusion-matrix driven QA. Deliverables include intent/slot JSON, CSV, and conversation-level annotations that plug into NLU stacks or modern LLM routers.

03

Document taxonomy, topics, and hierarchical labeling

Create multi-level taxonomies for knowledge bases, internal wikis, policy libraries, and product catalogs. Abaka builds guideline examples, edge-case rules, and reviewer playbooks to reduce drift as the taxonomy evolves. Outputs can be multi-label CSV/JSON, YAML label maps, and dataset cards to support training, evaluation, and governance.

04

Policy and safety labeling for production guardrails

Annotate toxicity, self-harm, regulated content, privacy leakage, and policy violations with clear severities and rationales. We structure review to separate sensitive adjudication from high-volume passes and maintain audit-friendly records in Abaka Forge. This is commonly paired with RLHF preference data and red-team evaluation sets for safer deployments.

05

RLHF preference labeling and instruction tuning signals

Collect pairwise preferences, rubric-based scoring, and instruction-following judgments aligned to your product. Abaka’s scholar-network domains (math, coding, medicine, law, business) support complex tasks where generic labeling fails. We deliver JSONL with prompts, responses, ranks, rationale fields (when desired), and reviewer metadata for reproducible training runs.

06

Expert text labeling for math, coding, and science

For advanced reasoning datasets, we route tasks to domain-specialized reviewers—mathematics (including Lean4), coding, and science—so labels reflect correct solutions, not superficial patterns. Abaka Forge enables multi-pass verification and disagreement analysis. Outputs include structured solutions, unit-test style validations, and JSONL schemas suitable for SFT and evaluation.

07

Multilingual annotation with locale-specific QA

Scale annotation across 50+ countries with language-aware guidelines and localized examples. We handle translation QA, dialectal variation, and locale-specific policy interpretation while keeping a unified taxonomy. Deliverables include language-tagged JSONL, parallel corpora metadata, and consistent label maps to support multilingual LLM training and evaluation.

08

End-to-end program management and measurable QA

Run annotation like a production system: onboarding, rubrics, sampling, adjudication, and weekly reporting. Abaka Forge supports task routing, reviewer calibration, and audit trails while maintaining segregated secure pipelines. You get stable throughput planning, change-control for guidelines, and clear acceptance criteria so your training schedule stays predictable.

How It Works

1) Day 0–3 — Scope, schema, and acceptance criteria

We align on your use case (NER, intent/slot, taxonomy, RLHF), define label schemas, and agree on measurable acceptance gates. You share sample data and edge cases; we propose guidelines, QA design, and output formats (JSONL/CSV/CoNLL). Security and access controls are finalized up front.

2) Week 1–2 — Pilot batch with calibration + QA

Abaka runs a pilot to validate guidelines and measure reviewer agreement. We use calibration rounds, gold sets, and adjudication queues in Abaka Forge to surface ambiguity early. You review pilot outputs, adjust rules, and sign off on the “definition of done” before scaling.

3) Week 2–3 — Scale production with controlled throughput

We expand to a production team sized to your weekly target while keeping consistent reviewer training and sampling. Throughput is planned to avoid fatigue (up to 500 files/day per annotator) and to maintain quality gates. Deliveries follow your preferred cadence and file formats.

4) Ongoing — Drift control and change-managed updates

As your taxonomy evolves, we manage change requests with versioned guidelines, backfill strategies, and targeted re-annotation only where needed. We track disagreements, edge-case patterns, and label distributions so you can prevent silent drift across releases.

5) Weekly — Reporting, metrics, and continuous improvement

You receive weekly reporting on volume, QA results, and issue categories, plus recommendations for rubric refinements and automation opportunities. We prioritize the highest-impact fixes—reducing rework and improving dataset consistency as your model, product, and policies evolve.

Modality & Format Coverage

Text is the core, but your dataset rarely stays text-only. Abaka Forge supports multimodal labeling and RLHF workflows so you can keep one QA system and one delivery standard across modalities.

Success Story

A leading enterprise GenAI team

The team needed a text annotation company to build a reliable instruction-tuning and evaluation dataset from internal knowledge and support interactions. Early batches showed label drift across intents and policy categories, and the team’s engineers were spending too much time adjudicating disagreements instead of improving retrieval and routing. They also needed secure handling and strong IP provenance because the dataset contained sensitive, business-specific information that could not be exposed to uncontrolled tooling or reused by a vendor.

Abaka scoped a unified schema for intents, entities, and policy labels, then ran a pilot with calibration rounds to lock down ambiguous edge cases. Using Abaka Forge, we set up gold sets, sampling, and adjudication queues, and routed complex categories to domain-specialist reviewers. We added versioned guidelines and a change-control loop so new intents and policies could be introduced without breaking historical consistency. Deliverables were produced as JSONL and CSV exports for direct integration into the team’s training and evaluation pipelines.

With a stable labeling system and multi-layer QA, the team scaled production while reducing internal adjudication time and preventing silent drift between batches. The dataset became consistent enough to support weekly model iteration and downstream evaluation, with security controls and exclusive ownership maintained throughout. Final deliveries included calibrated intent/slot labels, normalized entities, and policy categories packaged for training and benchmarking, improving turnaround time and enabling measurable quality gates—achieving 99% accuracy targets and launching the program in 2–3 weeks.

Frequently Asked Questions

How much does a text annotation company cost?
Pricing depends on task type (NER vs. intent/slot vs. RLHF), domain complexity, and QA depth. Abaka offers real, transparent starting points: STEM generalist work is typically $12/hr, and LLM math/coding annotation is $18/hr when expert review is required. For dense captioning on multimodal programs, pricing can be $6/hr, and image editing tasks can be $8/hr. We’ll scope a pilot batch and provide a clear per-hour plan, expected throughput, and QA sampling so you can forecast total cost.
How fast can you start and deliver the first batch?
Most teams can start with a pilot in 2–3 weeks, depending on security onboarding and how mature your guidelines are. In Day 0–3 we align on schema, formats, and acceptance criteria, then run calibration during Week 1–2 to validate edge cases. Production scaling typically begins in Week 2–3 with controlled throughput and weekly deliveries. If you already have stable guidelines and a clean schema, timelines can be faster; if not, we’ll prioritize drift-proofing before volume.
What text annotation formats do you deliver?
We deliver in the formats your training and evaluation pipeline expects—commonly JSONL for LLM workflows, CSV for analytics and classical ML, and CoNLL/TSV for NER and sequence tagging. We also support BIO/IOB2 tag outputs, YAML label maps, and dataset cards describing schema and QA. If you need custom fields (reviewer metadata, rubric scores, adjudication flags), we’ll define a stable schema so downstream processing stays deterministic across versions.
What accuracy can you achieve for text labeling?
Abaka targets high accuracy through process design: calibration rounds, gold sets, multi-layer QA, and adjudication for disagreements. The right metric depends on your task—span boundary consistency for NER, confusion patterns for intents, or rubric agreement for RLHF. We commonly work toward 99% accuracy targets when the schema is well-defined and reviewers are properly calibrated. If your label space is evolving, we’ll propose drift controls and sampling so quality stays stable between batches.
How do you keep sensitive text data secure?
We operate with SOC 2 and ISO 27001-aligned controls and support GDPR and CCPA requirements. Projects run under strict NDAs with segregated secure pipelines and access controls tailored to your data classification. We maintain audit trails and controlled exports, and we do not repurpose or resell your data—ever. If your team requires additional constraints (limited fields, redaction, or separate environments), we’ll incorporate those into the workflow before the pilot starts.
Can you annotate multilingual text and non-English datasets?
Yes. Abaka supports annotation across 50+ countries and can staff locale-aware reviewers for multilingual NER, intent/slot, taxonomy labeling, and RLHF judgments. We treat multilingual work as more than translation: we adapt examples, clarify dialect-specific edge cases, and ensure policy interpretations are consistent across locales. Outputs include language tags, consistent label maps, and unified schemas so you can train multilingual models or evaluate cross-lingual robustness without format drift.
How are you different from other text annotation vendors?
Abaka is built for frontier AI programs that need both scale and rigor. We combine domain-specialist reviewers (math, coding, medicine, law, business) with multi-layer QA and Abaka Forge workflows, rather than relying on generic labeling alone. We also never build models that compete with you, and your data remains exclusively yours—never repurposed, resold, or shared. Finally, we’re self-funded and profitable, reducing incentives that can compromise data governance.
What if I need to change the taxonomy or guidelines mid-project?
Change requests are expected, especially for evolving products. We manage updates through versioned guidelines, structured change logs, and targeted backfills so you don’t have to re-annotate everything. During weekly reviews, we identify which labels are impacted, propose a migration strategy, and implement A/B checks to confirm consistency. Abaka Forge helps keep the project auditable: you can trace which guideline version produced each batch and what QA gates were applied.
Can we run a paid pilot before committing to a large program?
Yes. A paid pilot is the recommended path for most teams: we validate the schema, measure agreement, and confirm delivery formats before scaling. The pilot typically includes calibration, gold sets, and adjudication so you can see how drift and edge cases are handled in practice. You’ll receive a pilot report with quality findings, recommended guideline updates, and a production plan—team size, throughput expectations, and QA sampling—so scaling is a controlled step, not a leap of faith.
Who owns the labeled data and can you reuse it?
You own the data and the outputs. Abaka does not repurpose, resell, or share your datasets, and we do not use them to build competing models. We maintain full IP provenance and keep work products tied to your project under strict NDAs and segregated pipelines. If you need additional contractual language around exclusive ownership or retention policies, we’ll align during onboarding so expectations are explicit before any labeling begins.
What tools do you use for text annotation and QA?
We use Abaka Forge—our platform for collection, cleaning, annotation, and production workflows. It supports QA sampling, adjudication, reviewer calibration, and export pipelines across modalities, including text and RLHF. If your team already uses internal tooling, we can align on a compatible output schema and delivery process. The goal is repeatable, auditable annotation operations—not manual, one-off batches that are hard to reproduce.
What is the minimum dataset size or engagement to get started?
You can start small. Many teams begin with a pilot sized to validate guidelines and edge cases—enough volume to measure disagreement patterns without overspending. We’ll recommend a minimum that matches your task (for example, a representative set across intents, languages, or document types) and define acceptance criteria. From there, scaling is straightforward: we keep the same schema, QA gates, and delivery formats while increasing reviewer capacity and throughput.
