qualityAcceptableUncertainThreshold

There are documents for which the quality analysis model is uncertain, meaning that the model is not sure if the document is acceptable or not. E.g., the model may report a document quality to be ACCEPTABLE with 60% confidence. Depending on the value of this threshold, the document in this case will be reported as ACCEPTABLE or UNCERTAIN. The default value of 0.5 will typically lead to a good balance between the number of documents reported as ACCEPTABLE and UNCERTAIN. A lower value will lead to fewer UNCERTAIN documents, but unacceptable documents will more often be reported as ACCEPTABLE (false positives). A higher value will lead to more borderline documents being reported as UNCERTAIN, but unacceptable documents will be reported as ACCEPTABLE less often. If 0, no documents with a predicted quality of ACCEPTABLE will be reported as UNCERTAIN, regardless of the model's confidence, unless the document has very few symbols (see minEstimatedNumberOfSymbolsForDocument). If 1, almost all documents with a predicted quality of ACCEPTABLE will be reported as UNCERTAIN. Must be in the range of 0, 1.

Default is 0.5
