Hi @PengLU1101 ,
you can find an explanation of the different encodings in this paper:
https://arxiv.org/abs/1707.06799

The network supports BIO, IOB, and IOBES encoding. The names of these encodings are not really fixed in literature. Our BIO encoding is sometimes called IOB and in other cases it is called IOB2. Quite confusing.

IOBES and BIOES is usually the same encoding.

For our implementation I recommend the BIO encoding: B- notes the start of a tag, I- are the following tokens of the same tag and O is used for every token that has no tag.

Thanks so much.
