How to parse CCRL-4040 pgn comments
Posted: Tue Dec 05, 2017 12:51 pm
Hello Everybody,
Newbie here, first of all I would like to thank you for this great project!
I am working on a neural network based evaluation, so I thought to use the CCRL database for training. The commented database contains the evaluation, but the format seems somewhat inconsistent to me. My main problem is the sign of the evaluation. Sometimes it alternates between players, sometimes not.
Of course, the white player always reports from his perspective, but to use the black side I need more info. Does the sign depend on the engine output, or was there any change during the years? (I see changes in the book move comments, but those are relatively straightforward)
Any information about the comment format would be helpful.
Thank you very much!
All the best,
Krisztián
