Overlap [Obj,String]

Description

Computes set operations (intersection, union, difference) between inputs A and B. Comparisons are performed tuple-wise, i.e. two inputs are equal when both columns are. By default, no duplicate elimination is performed. Use Score aggregation parameter to change that.

Input

• A [OBJ,STRING]: a list of objects (left operand)

• B [OBJ,STRING]: a list of objects (right operand)

Output

• INTERS [OBJ,STRING]: the intersection between A and B

• UNION [OBJ,STRING]: the union between A and B

• DIFF [OBJ,STRING]: the difference between A and B (A - B)

Output scores can be aggregated and/or normalised.
