It shows for each annotation set the split-half reliability using the full set of annotations (10N per half-set) as well as partial sets obtained by choosing k rs annotations per term for rating scale (where k rs ranges from 1 to 10) or k bws annotations per 4-tuple for BWS (where k bws ranges from 1 to 5).
• Fixed granularity: in some cases, annotators might feel too restricted with a given rating scale and may want to place an item inbetween the two points on the scale.
