Text Annotation Beyond Keywords: 16 Intermediate Challenges | Label the Meaning

One word can change the label. Can you explain why? Practice intermediate text annotation through 16 pause-and-answer challenges, worked examples and detailed reveals. Learn to separate intent from sentiment, choose exact entity spans, validate character offsets and BIO tags, handle negation and speaker attribution, preserve uncertainty, and review AI-generated labels. The workshop also covers relation direction, ambiguous coreference, English–Romanian meaning checks, reviewer calibration, precision/recall/F1, export validation and evaluation-set leakage. No narration: read the examples, enjoy the calm instrumental music, and pause when you need more time. Earn one point when both your answer and reasoning match.
