Good explanation of Bayes. Certainly clarified things for me ...

I was actually thinking of doing Bayes on different ways that the data could get mangled.

I think I have an idea of what might work:

  1. Compute the "distance" from one string to another in terms of 3 different operations.
    • inserting a character
    • deleting a character
    • swapping substrings
    Having it run from 0 being as far apart as possible to 1 being identical strings would be ideal.
  2. Manually figure out a point scoring system so that for each column in the two records I add and subtract points from an overall score based on a function of the distance separating the two strings.
  3. Call the records duplicates when the overall score goes over a predefined threshold.

So superficially at least it looks like SpamAssassin ...
