Data annotation
Data Labeling & Annotation Experience Data Annotation Specialist (Freelance / Remote) 2023 – Present Annotated large datasets for Natural Language Processing (NLP) and machine learning models. Labeled text data for intent classification, sentiment analysis, and entity recognition tasks. Categorized and structured raw datasets to improve supervised learning accuracy. Reviewed and corrected model outputs to reduce hallucinations and inconsistencies. Applied detailed annotation guidelines to ensure high inter-annotator agreement. Flagged ambiguous or biased data points to improve dataset quality. Conducted quality assurance (QA) checks on labeled data before submission. Collaborated with AI teams to refine annotation standards and improve model performance. Worked with structured formats such as JSON and CSV for dataset preparation.
