OpenNLP NameFinder training, "Found unexpected annotation"

Question

In training my NameFinderME, I get the following error message:

My data looks as follows: <START someTag> some text <END>

Computing event counts... java.io.IOException: Found unexpected annotation:

In everything else Google has found me for this error message, it's always a simple error in the spacing of the training data (e.g., change <START:entity>some text<END> to <START:entity> some text <END> . This isn't applicable to me (it's all correctly spaced.) It's all UTF-16, and specified to be so when I set up the objects to do the training. Any ideas on what could be wrong?

Thank you,

Answer 1

The data is incorrect. Instead of <START someTag> I need <START:someTag>. I was using a space instead of a colon.

Answer 2

Also, when occurring problem like this, please be sure your and tags are surrounded by a space, so instead of Next person, <START:person>Rahul Vashishth<END>, is 61 years old. use Next person, <START:person> Rahul Vashishth <END>, is 61 years old.
