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 x and y. 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 will describe an algorithm with non-trivial guarantees on
this problem, and give a matching lower bound.
