Doccano

Data Annotation Specialist (Freelance)

DoccanoTextEntity Ner Classification
I performed text annotation for sentiment analysis, intent classification, entity tagging, and content categorization for chatbot and NLP training. The work required precise recognition and accurate application of category and entity labels. Datasets were labeled to a high standard with robust inter-annotator agreement and quality checks. • Labeled text for sentiment and intent classification • Tagged entities for NER and chatbot training • Ensured data consistency through rigorous validation • Maintained high accuracy and annotation standards
