Embeddings of Label Components for Sequence Labeling:A Case Study of Fine-grained Named Entity Recognition
Table 6: Comparison between the baseline and the proposed models in span (only considering B, I labels).

A1SS1SSS0Px2 Performance for entity span boundary match The performance of the proposed models was comparable to the baseline model. This indicates that there is a performance difference not in identification of entity spans (entity detection) but in identification of entity types (entity typing).
