Each bin must be assigned a setting that determines what decision is made:
o
/ original: select the original token as correct.k
/ kbest: select the top k-best candidate as correct.d
/ kdict: select the first lower-ranked candidate that is in the dictionary.a
/ annotator: defer selection to annotator.
Once the report and settings are generated, it is not strictly necessary to update them every single time the model is updated. It is however a good idea to do it regularly as the corpus grows and more tokens become available for the statistics.
