Straight Through Processing - Document Automation WhatAbout Probability? Upuntil now,we haveonly shown how to use confidence scores to separate likely accurate data from inaccurate data. So how do wecalculate probability? The answer is that we must analyze a large sample set (that 1000 invoices is a good number) of representative data. “Representative” means that your sample data resembles your actual data. And then, you have to perform alotmoreanalysisto getto an understandingofindividual score accuracy. For instance, once again using the analogy of the exam, you will calculate the accuracy rate of all answers above and below the threshold. Youmight findthat 450answersoutof500,whichare above the threshold are accurate. This equates to an accuracy rateof90%.Andthen,youmightgroupeachanswerbythescore andfindthat,ourof50answerswithascoreof85,48arecorrect, yielding an accuracy rate of 96%. Youmight calculate all of these numbers. Ultimately, you can get to a level of understanding to calculate the accuracy rate for each confidence score. This is how confidencescoresshouldbeevaluatedand used. The reality is that this is a lot of work that few organizations performduetothecomplexityandtime requirements. 30
