There are slight changes with the script, "performance.pl"
Changes are :
(1) we do not take raw words. only stems or lemmas.
(2) the current performance.pl does not use "stems" but "lemmas" only.
You can find the updated script in Google Group.
To use stems, type
"perl performance.pl teamname.stm" (e.g. perl performance.pl MELB.stm)
Or to use lemmas, typoe
"perl performance.pl teamname.lem" (e.g. perl performance.pl MELB.lem)
If you have a trouble, let me know please.
Thank you.
