Text Annotation & NLP Data Labeling
Structured NER, sentiment, intent classification, and LLM training datasets.
VAIKA GROUP provides structured text annotation and Natural Language Processing (NLP) data labeling services for organizations developing language models, conversational AI systems, search engines and automated text classification solutions.
Our text annotation workflows transform unstructured text into machine-readable datasets through Named Entity Recognition (NER), sentiment analysis, intent classification, document categorization and conversational dialogue evaluation.
We use domain-specific taxonomies and consistent labeling guidelines to support specialized NLP applications across industries such as finance, healthcare, legal services and customer support.
Why Organizations Outsource Text Annotation & NLP Data Labeling
Replaces noisy automated tags with consistent human linguistic judgment for specialized LLMs, search relevance, and document intelligence systems.
Our 8-Step Production Process
Structured guidelines, trained human operators, and multi-stage verification ensure predictable throughput at any dataset scale.
Text Data Assessment
Review source documents, conversations, text corpora and labeling objectives to establish the required annotation taxonomy.
Named Entity Recognition
Identify and label entities such as organizations, people, locations, dates, financial terms and domain-specific terminology.
Sentiment & Emotion Annotation
Classify text based on positive, negative and neutral sentiment, emotional tone and contextual meaning.
Intent & Text Classification
Categorize sentences, documents and customer conversations according to predefined intent classes and business taxonomies.
Conversational Data Evaluation
Review dialogue turns, response relevance, contextual consistency and potential hallucinations in AI-generated conversations.
Domain-Specific Labeling
Apply specialized annotation guidelines for legal, healthcare, finance and other industry-specific datasets.
Quality Validation
Conduct consistency checks, taxonomy alignment reviews and multi-annotator quality assessments.
Dataset Delivery
Export validated annotations in structured JSONL, CSV or other requested formats.
