Scoring Field Identification Accuracy

Scoring Field Identification Accuracy

In order for the system to score the accuracy of the machine or a data keyer, a field must first achieve Quality Assurance (QA) consensus; consensus means that two identifications for the field must be matching. In other words, when the field ID of the machine (with high confidence) or that of a data keyer matches what is determined in QA consensus, then the data keyer or the machine is marked as accurate. The chance of two locations matching exactly is nearly impossible. As such, we ask users to confirm the location of the previous entry in order to establish consensus rather than drawing a new box every time.

Scoring Field Identification

With release 25.0.0, the system scores every human entry for Field ID. However, consistent with previous releases, there are specific instances where this is not the case:

The major difference between Transcription QA and Field ID QA is that Field ID QA is sampled and done at the page level whereas Transcription QA happens at the individual field level.

Here are a few example scenarios:

Example 1:

Extraction source Field ID entry Field ID accuracy
Machine Location A Accurate
QA (keyer 1) Confirms Location A Accurate
Consensus Location A --

Example 2:

Extraction source Field ID entry Field ID accuracy
Machine Location A Inaccurate
QA (keyer 1) Location B Accurate
QA (keyer 2) Confirms Location B Accurate
Consensus Location B

Example 3:

Extraction source Field ID entry Field ID accuracy
Machine Location A
(low confidence)
Not Measured
Supervision Field ID (keyer 1) Location B Accurate
QA (keyer 2) Confirms Location B Accurate
Consensus Location B

Example 4:

Extraction source Field ID Entry Field ID Accuracy
Machine FIELD IS NOT PRESENT Accurate
QA (keyer 1) Confirms that 
FIELD IS NOT PRESENT
Accurate
Consensus Location B

Abandoned fields

There is one situation in which the affected entries will be abandoned and therefore not counted towards accuracy reporting:

A QA entry is abandoned if no consensus is reached on location after three QA entries.

Extraction source Field ID entry Field ID accuracy
Machine Location A Abandoned
QA (keyer 1) Location B Abandoned
QA (keyer 2) Location C Abandoned
QA (keyer 3) Location D Abandoned
Consensus --
