For a certain class and document, each classification engine may return different result types. The following result types are possible.
- Confidence
- This document belongs to a specified class with a probability given in percent.
- Yes
- This document definitely belongs to this class.
- Maybe
- This document might belong to this class.
- No
- This document does definitely not belong to this class.
- -
- This method is not applied.
The various classification methods are not equally reliable. For example, it is dangerous to decide that a document is an invoice based only on the fact that it is a certain size. The table below presents the possible results for each classification method. It also shows which result type is returned by default.
| Engine | Result | Default or Configured |
|---|---|---|
| Brainware Classify | Confidence Yes No |
Default Configured Configured |
| ASSA Classify | Confidence Yes No |
Default Configured Configured |
| Phrase Classify | Confidence Yes No |
Default Configured Configured |
| Image Size Classification | Maybe No |
Default Default |
| Forms Classify | Yes Maybe Confidence |
Default Default Configured |
| Layout Classify | Confidence Yes No |
Default Configured Configured |
| Brainware Layout Classification | Maybe No Confidence |
Configured Configured Default |
| Language Classify | Maybe No Confidence |
Configured Configured Default |
Yes and No are called absolute results. If the program is configured accordingly, they are obtained if confidence levels returned by one of the methods are either very high or very low.
If a method returns Yes for a class, the combined result is Yes. Classification of the document stops at this stage. All other classes are excluded automatically.
If a method returns No for a class, the combined result is No. Within the current branch, classification of the document stops at this stage: All child classes are excluded automatically.
You can use absolute results to speed up the entire classification process. Image size classification is a suitable method to quickly exclude entire branches. You can use Brainware Layout Classification to positively confirm formal classes quickly. The same is true for forms classification.
