Given two sets of entities X and Y, entity matching aims to decide whether x and y represent the same entity for each x in R and y in Y. As the last resort, human experts can be called upon to inspect every (x, y), but this is expensive because the correct verdict could not be determined without investigation efforts dedicated specifically to the two entities x and y involved. It is therefore important to design an algorithm that asks humans to look at only some pairs, and renders the verdicts on the other pairs automatically with good accuracy.
We describe algorithms with non-trivial guarantees on this problem with an active monotone classification approach. We also prove lower bounds that establish the asymptotic optimality of our solutions for a wide range of parameters.
