Text Annotation Services

High-quality text annotation and NLP data labeling services for AI models, chatbots, sentiment analysis, intent classification, entity recognition, and Arabic language datasets.

Managed Text Annotation for AI and NLP Projects

Contalents helps AI companies, data teams, and technology providers build accurate text datasets through managed annotation teams, clear labeling instructions, quality control, and scalable delivery workflows.

Entity Annotation

Label names, locations, organizations, products, dates, references, and key entities for NLP models.

Sentiment Analysis

Classify customer opinions, emotions, tone, satisfaction, and intent across text datasets.

Intent Classification

Train chatbots and AI assistants by classifying user intent, queries, requests, and conversation patterns.

Arabic NLP Data

Specialized Arabic text annotation for MENA-focused AI models, language datasets, and multilingual projects.

Why Text Annotation Matters

AI models cannot understand language accurately without structured training data. Text annotation helps machine learning systems classify meaning, detect entities, understand sentiment, identify intent, and improve language understanding across real-world use cases.
  • Improve NLP model accuracy
  • Train chatbots and AI assistants
  • Build Arabic and multilingual datasets
  • Classify customer feedback and conversations
  • Support search, moderation, and recommendation systems
  • Scale data labeling with managed QA

How Our Text Annotation Process Works

A structured workflow for consistent annotation quality, clear instructions, and scalable delivery.

1. Scope & Guidelines

We define dataset type, annotation classes, labeling rules, edge cases, QA criteria, and delivery format.

2. Team Training

Annotators are trained on your project instructions, sample cases, labeling standards, and expected quality level.

3. Pilot Batch

We complete a pilot batch to calibrate quality, clarify edge cases, and align output before scaling.

4. Production Labeling

The annotation team processes the dataset according to agreed volume, timeline, and quality workflow.

5. Quality Control

Output is reviewed through sampling, consensus checks, corrections, and quality feedback loops.

6. Delivery & Reporting

We deliver structured annotated data with progress reporting, issue logs, and quality notes when required.
