Missing B-ORG but with I-ORG and E-ORG #46

Closed junwei-h closed 2 years ago

junwei-h commented 2 years ago

I wonder if anyone else hit the situation where B-ORG is missing but I-ORG, E-ORG are in the tag.

Moonstone is tagged as I-ORG without a B-ORG. I thought a tag will always start with a "B-" tag, like an open parenthesis followed by a close parenthesis. Any ideas what may cause this case? Thank you.

The CRF layer does not force all the tag sequences should be correct (but it helps). I suggest you may manually fix these problem (I-ORG->B-ORG for moonstone)
