Monotone Boolean matching functions
f(x) = 1 if the pair described by vector x = (x1,x2,…,x11) are are most likely a match, 0 otherwise
monotonicity defn: each variable has a non-negative effect on matching (e.g., with all other vars fixed, more common co-authors (x3) implies a more likely match)
mbfs are simple and intuitive which facilitates understanding, remembrance, use, interpretation and validation of matching rules, e.g. (x1 AND x11 > -50) OR (x3 > 1) OR (X4 > 2 AND x7 > 2) means (middle names’ inits match AND freq of lastname < 50) OR (common co-authors > 1) OR (common title words > 2 AND common mesh headings > 2)
