This paper addresses the mitigation of medi- cal errors due to the confusion of sound-alike and look-alike drug names. Our approach involves application of two new methods— one based on orthographic similarity (“look- alike”) and the other based on phonetic sim- ilarity (“sound-alike”). We present a new recall-based evaluation methodology for deter- mining the effectiveness of different similar- ity measures on drug names. We show that the new orthographic measure (BI-SIM) outper- forms other commonly used measures of sim- ilarity on a set containing both look-alike and sound-alike pairs, and that the feature-based phonetic approach (ALINE) outperforms or- thographic approaches on a test set contain- ing solely sound-alike confusion pairs. How- ever, an approach that combines sev...
