Your question is Named Entity Recognition Scenario. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me how you would approach a scenario-based problem in named entity recognition (NER). Explain how you would define the entity schema, prepare and annotate data, select a model, handle subword tokenization, train the system, and evaluate its errors. Include practical considerations for nested entities, class imbalance, unseen terminology, and deployment.
