Below is a table showing how two human judges rated the relevance of a set of 12 documents to a particular information need (0 = nonrelevant, 1-relevant). Let us assume that you've written an IR system that for this query returns the set of documents 4, 5, 6,7,8) Document ID 2 4 0 10 0 12 Calculate the kappa measure between the two judges.
