[dedupe] for strict abbreviations (defined as sharing a prefix and a suffix, and containing matches+gaps only by the subtotaling affine gap measure), using the greater of the two scores. This accounts for cases where the abbreviated version may have a much higher weight in one string than the non-abbreviated version does in the other. Same for acronym alignments. Making sure there's a common prefix in regular abbeviation detection Capping the Soft-TFIDF similarity at 1.0.
