New Features

• Set where filters in all classification types (#985)
  This feature allows narrowing down objects in a classification through setting where filters.

  A total of three filters can be set (all three are optional).

  • sourceWhere: This limits the to-be-classified (or "unclassified") items which will be processed during a classification run.
  • trainingSetWhere: This limits the training set. This filter can only be used with classification types which rely on a training set, such as "type": "knn"
  • targetWhere: This limits the potential targets (or "labels") of a classification. This filter can only be used on classification types which don't have a training set, but rather produce a direct relationship between source and target, such as "type": "contextual"

  For more elaborate examples on when to use which filter, see this post.

  The type/structure of the where filter object for all three options is identical to the those of the existing where filters currently present in the GraphQL API.

Fixes

• Incorrect defaults in classification of type contextual (#1045)
  Prior to this version the optional field k would always default to 3. This is indeed the desired behavior for a classification of type knn. However, it would also be set for contextual where the field doesn't make sense. This fix makes sure that the defaults are only set where appropriate.
