n best decode #161

Hi,I want to know how the n best decodeing work to increase F1 on NER task, I don't know why n best=10 will increase F1

jiesutd commented 3 years ago

n-best will not improve F1, but it will give more choices of the decoding results. In some cases, the best result is not in the top-1 prediction but in the second/third predictions.
