How SpanProto Boosts Few-Shot NER Accuracy with a Two-Stage Span Approach

SpanProto, a two‑stage span‑based prototypical network, dramatically improves few‑shot named entity recognition by extracting candidate spans with a global boundary matrix and classifying them via prototypical and margin learning, achieving notable gains on the Few‑NERD benchmark with minimal labeled data.
