CoNLL-X evaluation script:
[perl] eval.pl [OPTIONS] -g <gold standard> -s <system output>
This script evaluates a system output with respect to a gold standard.
Both files should be in UTF-8 encoded CoNLL-X tabular format.
Punctuation tokens (those where all characters have the Unicode
category property "Punctuation") are ignored for scoring (unless the
-p flag is used).
The output breaks down the errors according to their type and context.
Optional parameters:
-o FILE : output: print output to FILE (default is standard output)
-q : quiet: only print overall performance, without the details
-b : evalb: produce output in a format similar to evalb
(http://nlp.cs.nyu.edu/evalb/); use together with -q
-p : punctuation: also score on punctuation (default is not to score on it)
-v : version: show the version number
-h : help: print this help text and exit
