CommentsThe tests above were completed on 15 different product comparisons with universities, government, and private companies (80K to 8M records). This includes the effect of false positives. Need multi-threared, in memory, so-sql processing to optimize for speed and accuracy. Speed is important, the more match terations you can run, the more accurate your results will be. Include base license costs, 2014 proces or later, in-house, includes salary benefits. Not in-house implementations had lost the member who ran and understood the matching program.A metric for ease of use. This is the time of first result, not necessarily full cleansing.
