I had already worked around some problems my custom classifier was causing with Beta 2 related to it’s use of a recursive invocation of the classifier services, but @noahsmark proposed a better way to get this done in Beta 2 that would simplify the code a bit and get rid of the need to do the recursive invocation in the first place. This involved switching away from a custom classifier and instead implementing a custom
ITagger service instead.
The end result (to the user) is the same, but the code is definitely cleaner! In retrospect, though, naming the extension “KeywordClassifier” might not have been the best choice :).
