NLP Annotation Services for NER, Intent, Sentiment, and Conversational AI
NLP Data Annotation Services
DataVLab provides NLP annotation services for teams training chatbots, search, classification models, and LLM-powered assistants. We label text and conversations for intent, entities, sentiment, relations, and dialogue structure using project-specific guidelines and multi-stage QA. Workflows scale from a calibrated pilot to ongoing production labeling with consistency reporting and ontology refinement.
NLP annotation services for NER, intent, sentiment, relations, and conversations.
Multilingual workflows and domain ontologies tailored to your use case.
Multi-stage QA and reporting to keep labels consistent at scale.
NLP annotation is the labeling of text so models can learn to classify intent, extract entities, detect sentiment, and understand relationships and dialogue context. High-quality NLP training data depends on clear taxonomies and consistent review.
We support named entity recognition (NER), intent classification, sentiment and emotion labeling, relation extraction, topic classification, and multi-turn conversation tags. We can adapt to your domain ontology and provide multilingual workflows where needed.
Use cases include customer support automation, routing and triage, product search and categorization, compliance and safety classification, and structured datasets for LLM fine-tuning and evaluation. We can build balanced datasets and review edge cases to improve model robustness.
QA includes double-pass review, sampling audits, taxonomy checks, and adjudication for disagreements. For sensitive text data, we support secure handling and GDPR-aligned processing, including EU-only annotation options where required.
What DataVLab delivers for NLP annotation
Structured text and conversation labeling with calibrated guidelines and measurable quality review.
Intent Classification for Chatbots
Labeling customer requests across domain specific intents
We classify user utterances into predefined intents to help conversational agents route queries, improve response relevance, and reduce fallback rates.
Named Entity Recognition
Token level tagging for people, organizations, products, and domain entities
We annotate entities with fine grained labels to support information extraction, document processing, and domain specific language models.
Sentiment and Emotion Labeling
Scoring tone, polarity, and emotional categories
We apply sentiment and emotion taxonomies to customer feedback, reviews, and conversational datasets.
Relation Extraction
Identifying how entities connect within text
We annotate semantic relationships such as ownership, affiliation, causality, and product associations to support structured knowledge extraction.
Multilingual NLP Annotation
Language specific tagging across European, Middle Eastern, and Asian languages
Our teams annotate multilingual datasets with consistent guidelines adapted to linguistic context and cultural nuance.
Conversational AI Turn Annotation
Structuring multi turn dialogues for training assistants
We segment dialogue turns, label speaker roles, and apply conversational structure to improve assistant grounding and coherence.
