 **BH**: Jirka ma pravdu. Pocitani skore musi byt objektivni. Proto jsem vzorecek upravila tak, ze nebude pocitat shodu hrace vzhledem k rucni anotaci. **BH**: Jirka ma pravdu.

-  - kappa measure +(**JM**: Mluvil jsem kvůli měření mezianotátorské shody v anotování koreference se Zdeňkem a vyšlo z toho, že na měření shody na šipkách by použil prostě jen F-measure. Její smysl je jasný a je symetrická. Kappa je nevhodná kvůli tomu, že pravděpodobnost náhodné shody je poměrně nízká a těžko se určuje; kappa se hodí spíš pro klasifikační úlohy (proto ji použiju v Anjiině projektu na shodu v určování typu koreference, když už se shodli na šipce); ostatní (G-theory a Pearson correlation) neznám, jsem zvědav, co k tomu řekne Pavel.)
