Given profile A, the collective category for item j will be 1 in case a i,j =1 w 1 i > a i,j =0 w 0 i , and 0 otherwise.
5 we compute the overall weight for category 1 by adding up the corresponding weights for those coders that chose 1 for item j, and we do accordingly for the overall weight for category 0; finally, we choose as collective category that category with the larger overall weight.
