Fingerprint mode

A fingerprint for standalone documents changes Sensible's default behavior of running all the configs in a single document type. For example, if you extract company A and company B quotes, by default Sensible runs both the company A and the company B configs for a given document, then returns the extraction with the highest score.

The following tables show how this default behavior changes when you configure the following levels of strictness for a document type's fingerprints. You can configure strictness in the Sensible app in the document type settings tab:

Single-document file fingerprints

Strictness levelDescriptionIf more than one config's tests pass over 50%If no configs' tests passes over 50% or if no configs contain a fingerprint
standardIf any of the configs in the document type contain a fingerprint, then Sensible runs extractions using any configs that pass over 50% of the fingerprint tests.Sensible chooses the output from the passing config with the highest scoreSensible falls back to the default behavior of running extractions for the document using all configurations, and returns the one that has the highest score.
strictThe doc type must have at least one config containing a fingerprint.Sensible chooses the output from the passing config that has the highest score.Sensible returns a 400 error.

In the preceding table, Sensible calculates a score as follows:

classification score = num of non-null fields - penalties for validation errors or warnings, where penalties are as follows:

  • validation error penalty = 1 * num fields with validation errors
  • validation warning penalty = 0.5 * num of fields with validation warnings

The classification score is for comparing extractions within a single document type. To compare scores across document types, see Accuracy measures.

Portfolio fingerprints

When using fingerprints for segmenting portfolio files into documents, Sensible ignores the document type's fingerprint mode setting.
