What We Annotate

## Expert annotation across every *data modality*

Image, video, 3D annotation services, text annotation services and audio annotation services, each delivered by specialist annotator teams. From bounding boxes to 3D cuboids, from entity extraction to RLHF preference data, LXT covers every modality your model needs.

### Image Annotation

Bounding boxes, semantic segmentation, instance segmentation, polygon annotation, keypoints and landmark labeling across diverse image domains.

Bounding Box Segmentation Keypoints OCR

### Video Annotation

Frame-by-frame object tracking, action recognition, temporal segmentation and activity labeling for computer vision and surveillance AI systems.

Object Tracking Action Recognition Temporal Labels

### 3D Annotation Services

3D annotation services covering cuboid annotation, semantic segmentation of point clouds, lane marking and surface classification for autonomous vehicles, robotics and spatial AI.

3D Cuboids LiDAR Segmentation Lane Marking

### Text Annotation Services

Text annotation services spanning named entity recognition, intent classification, sentiment labeling, coreference resolution and RLHF preference data for language models and conversational AI.

NER Intent RLHF Sentiment

### Audio Annotation and Speech Data

Audio annotation services and audio data collection: transcription, speaker diarization, intent labeling, emotion tagging and QA for ASR, TTS and conversational AI training across 100+ languages.

Transcription Diarization 100+ Languages

### QA and Dataset Review

Independent QA review of annotations produced by other vendors, inter-annotator agreement measurement, adjudication and dataset remediation before training.

IAA Adjudication Remediation

The Problem

## Annotation quality breaks down when you scale *without the right controls*

Most annotation programs start well. The problems emerge when volume grows, the workforce turns over or edge cases start to pile up without a clear adjudication path.

### Label drift at scale

Annotation quality degrades as batch size grows, new annotators onboard or label guidelines are interpreted inconsistently. Without structured IAA measurement, drift goes undetected until model performance drops.

### Crowdsourcing misses specialist tasks

Generic crowd platforms handle simple classification. 3D annotation, clinical image labeling, legal entity extraction and RLHF preference data require specialists who understand the domain, not just the interface.

### Compliance requirements add risk

Healthcare, finance and legal annotation programs require strict data handling, consent documentation and audit trails. Non-compliant annotation workflows create legal exposure that shows up well after delivery.

QA Coverage

Our Approach

## Quality controls built into *every annotation workflow*

LXT does not sample for QA. Every production delivery goes through a structured review cycle before handoff, with named accountability at each stage.

- Annotation guidelines co-developed with your team before work begins
- Inter-annotator agreement measured and reported per batch
- Adjudication loop for ambiguous edge cases before delivery
- Dedicated QA team and named project manager on every engagement

How LXT Compares

## What you get with a *managed annotation partner*

Annotation platforms give you tools. LXT gives you outcomes. The difference shows up in delivery speed, consistency and what happens when edge cases appear.

| Factor | Self-service platforms | Crowdsourcing | LXT Managed Service |
| --- | --- | --- | --- |
| QA coverage | Sampling only | Majority vote | 100% review, adjudication |
| Domain specialists | General workforce | General crowd | Matched to your vertical |
| 3D / LiDAR annotation | Tool only, no workforce | Not supported | Dedicated 3D specialist teams |
| Compliance (HIPAA, ISO 27001) | Your responsibility | Limited | Certified workflows, audit trails |
| Geographic diversity | Depends on your team | Concentrated markets | 145+ countries by design |
| Named project manager | No | No | Yes, on every engagement |

Annotation at production scale

> LXT helps AI teams maintain annotation quality as volume grows, workforce turns over and edge case complexity increases. Managed delivery means one accountable team from guidelines through handoff.

Specialist annotators, built-in QA and a named project manager on every engagement.
