Precision / Recall Gate

Description

Given a set of items (SOURCE) and a set of relevant items (RELEVANT), lets SOURCE through only if the computed precision or recall is >= Threshold. Otherwise, the empty set is returned.

Input

  • SOURCE [OBJ]: a list of objects

  • RELEVANT [OBJ]: a list of objects

Output

  • PRECISION [OBJ]: SOURCE if precision is >= Threshold, an empty set otherwise

  • RECALL [OBJ]: SOURCE if recall is >= Threshold, an empty set otherwise

Parameters

  • Threshold the minimum value requested for precision or recall to let SOURCE through.

Output scores can be aggregated and/or normalised.
