A quick story for you. One of our customers, about two [or] three years ago, showed up and ran our software. We checked in afterwards and they said: Now we’ve got a 90-day project with our engineers to write some software to compare your results to our own homegrown results. I’m like, that’s crazy! We wouldn’t want to have everybody have to do that.

So, what we did is we launched a project. We created an audit tool – this is Python, it’s Apache-2.0 licensed open source. You can find it [here].

It allows you to take Senzing output and the output of another entity resolution engine (e.g. your homegrown results, your golden data set where you know what the answers are) and produce a delta between the two – the [differences between the two including] false positives and false negatives. Then we allow you to drill into it and ask why and get an answer about why something matched or didn’t.
