AI Data Labeling Services
Hansem Global labels and annotates AI training data in text, image, audio, and video formats for large-scale projects in Asian languages.
Why Hansem Global?
-
Built for continuous, ever-changing projects.
AI data work arrives nonstop and never looks the same: text one day, audio the next, evaluation after that. Some projects run for months while others must ship in two days. We're structured to absorb that flow without quality dropping, so no single task depends on any single worker.
-
Trained specialists, not basic labelers.
We staff projects with people selected for language judgment and domain understanding, organized in L1–L3 proficiency tiers and matched to each task's complexity. This is a different model from anonymous crowd labor priced to the bottom.
-
A specialized operation, not just a platform.
Years of production taught us where this work is won or lost: PM-led instruction design, rigorous workforce vetting, and an RMS built to run high-volume labeling. This operational depth is far harder to build than a normal translation project, and it's what clients are really paying for.
AI Data Services Offerings
Text Labeling
Text is the most widely used data type in AI training, and the type we handle most. We tag user intent, sentiment, context, and key entities so models can accurately interpret natural language, drawing on expert linguists across Asian languages and beyond. This kind of high-quality training data strengthens NLP applications like chatbots, sentiment analysis, and information extraction.
Tagging intent, sentiment, context, and key entities.
Audio Labeling
Spoken language varies by environment, intonation, dialect, and speaker. Our audio labeling prepares speech data for voice AI by transcribing audio accurately and labeling metadata such as emotion, language, and dialect. We also identify non-speech sounds, such as a glass breaking, to broaden recognition coverage. This kind of data supports ASR and voice-assistant development, and is also used in security and incident-response systems.

Image Labeling
Image labeling provides the training data behind computer vision, facial recognition, and other visual AI. We label objects, facial landmarks, and image-level classes so models can detect and classify visual information reliably. This kind of dataset is applied across autonomous driving, security monitoring, manufacturing quality inspection, and facial recognition development.

Video Labeling
Video labeling turns dynamic, frame-by-frame visuals into training data for vision AI. We track object motion across frames and label human and object actions and key events. This kind of data matters for models that must work in real-world conditions: autonomous driving, action recognition, CCTV surveillance, and event detection.

AI Data Experts and Global Delivery
Hansem Global staffs projects with trained AI data specialists managed by experienced in-house PMs and resource managers, because the outcome of this work depends on operations as much as headcount. Rather than passing a client's raw instructions to workers, our PMs work through each task from the worker's side and rewrite the brief to be precise and concrete, so workers succeed instead of dropping out. Recruiting at scale also surfaces real problems, such as ghost workers, falsified résumés, and coordinated cheating in qualification tests, which our resource managers screen out while verifying identity and protecting workers' personal data to earn their cooperation. Delivery runs across teams in Korea, Vietnam, China, Spain, Argentina, and the US, moving continuously across time zones to keep even two-day turnarounds on track, with depth concentrated in Asian languages (Korean, Japanese, Chinese, Vietnamese, Indonesian, and Thai) and other languages supported on request.
Technology Infrastructure and Security
Our infrastructure is built for enterprise data security and quality at scale. Unlike off-the-shelf tools that just store a worker database, our in-house Resource Management System (RMS) distributes large projects to 100+ vetted workers per language, simultaneously and continuously, with full traceability of the workflow. Sensitive data is handled under ISO 27001–aligned controls used in regulated fields like healthcare, legal, and finance, with a closed working environment and NDA available on request. From collection through labeling and validation, work runs on ISO-based processes with a three-step quality gate (QA, Review, and LQA) and KPI-driven feedback. When clients require it, our teams work directly within the client's own annotation platform.
