ABOUT
At Anotag, we make language understandable for machines.
Our Text Annotation Services empower NLP, generative AI, and document intelligence systems to extract meaning, intent, and sentiment from raw text data.
Whether you’re developing chatbots, search engines, fraud detection models, or language translation tools, our experts ensure every word, phrase, and entity is labeled with precision and context.
We combine linguistic expertise with AI-assisted workflows to deliver accurate, domain-specific annotations at scale fueling smarter, more human-like language models.
Things We Do
We offer a full range of text annotation types to support NLP, NLU, and text-based AI models.
01
Named Entity Recognition (NER)

Identify and categorize entities such as names, locations, organizations, and key terms to support information extraction and analysis.
02
Sentiment & Emotion Annotation
Tag opinions, tone, and emotions to help
models understand context, polarity,
and customer intent.
03
Intent Classification

Label user intents for conversational AI, chatbots, and voice assistants to improve response accuracy.
04
Text Classification & Categorization
Organize documents, messages, or reviews into structured categories for filtering, automation, and analytics.
05
Semantic & Contextual Annotation
Label relationships between words, concepts, and phrases to enhance meaning understanding in large language models.
06
Toxicity & Content Moderation
Detect harmful or inappropriate language to train moderation systems for social platforms and communication tools.
07
Linguistic & Syntactic Annotation
Tag parts of speech, grammatical structures, and dependencies for deep language
model training.
08
Custom NLP Workflows
We design annotation schemas for specialized domains like legal, healthcare, finance, or customer service AI.
