Breaking the Boundaries: A Unified Framework for Chinese Named Entity Recognition Across Text and Speech

EMNLP 2024finding

In recent years, with the vast and rapidly increasing amounts of spoken and textual data, Named Entity Recognition (NER) tasks have evolved into three distinct categories, i.e., text-based NER (TNER), Speech NER (SNER) and Multimodal NER (MNER). However, existing approaches typically require designi…
