NLP & Text Annotation

Training data for language models that actually understand language

Natural language processing demands annotation that captures context, intent, and nuance — not just keyword tags. Our NLP annotation teams are trained in linguistics and work across English, Vietnamese, Thai, Malay, and other Southeast Asian languages.

Capabilities

  • Named Entity Recognition (NER) — people, places, organizations, products
  • Sentiment analysis — fine-grained (positive, negative, neutral, mixed)
  • Text classification — topic, category, intent, urgency
  • Intent detection and slot filling for conversational AI and chatbots
  • Coreference resolution and relationship extraction
  • Question-answer pair generation for RAG and LLM fine-tuning
  • Instruction tuning datasets for RLHF pipelines

Image Annotation

Pixel-precise labels for computer vision at any scale

Computer vision is only as good as the ground truth it trains on. We deliver precise, consistent image annotations across every annotation type — from simple classification to complex instance segmentation — with multi-pass QA ensuring your model trains on clean data.

Capabilities

  • Bounding box annotation — 2D and rotated boxes
  • Semantic segmentation — pixel-level class labeling
  • Instance segmentation — individual object delineation
  • Keypoint and pose estimation annotation
  • Polygon annotation for irregular shapes
  • Image classification and tagging
  • Lane marking and road feature annotation for ADAS

Video Annotation

Frame-by-frame precision for dynamic scene understanding

Video annotation requires spatial and temporal consistency that static image labeling cannot provide. Our video annotation teams use professional tooling to track objects across frames, ensuring your models learn real-world motion patterns accurately.

Audio Annotation

Clean transcriptions and rich labels for voice-first AI

Voice AI requires training data that captures the full complexity of human speech — accents, emotion, overlapping speakers, and background noise. Our audio annotation specialists handle everything from clean studio recordings to noisy real-world audio.

3D Point Cloud Annotation

Spatial intelligence for robots and autonomous systems

LiDAR-based perception is the foundation of autonomous vehicles and industrial robotics. Our 3D annotation specialists work directly in point cloud environments to deliver precise spatial labels that your perception models can rely on.
