Static and dynamic data

You will receive the best accuracy if the location of the surrounding data and the formatting is consistent for each document being processed for the vendor.

The following table shows a breakdown of how surrounding data patterns affect accuracy.

Depending on the position of the fields, there may be up to two empty surrounding patterns.

For example, a field at the bottom right will not have a right and bottom pattern, which means only a top and left pattern will be used for extraction and confidence calculation, which may result in more false positives.

Pattern type Pattern Accuracy

Static

Left and/or Top + Right and Bottom

  • Fewer iterations are required to get good accuracy.

  • If the fields do not fluctuate, you may get good accuracy and confidence after the first iteration.

Dynamic

Left, Top, Right, and Bottom

  • More iterations are required to get good accuracy.

  • If the patterns surrounding the value fluctuate greatly (mainly character strings), the confidence will drop and you may receive false positives.

Empty

  • Right and Bottom

  • Left and Bottom

  • Right and Top

  • Left and Top

Depending on the position of the fields, there may be up to two empty surrounding patterns.

For example, a field at the bottom right will not have a right and bottom pattern, which means only a top and left pattern will be used for extraction and confidence calculation, which may result in more false positives.
