How well do NLP Classifiers work?Natural language processing
Demos paper – ‘Vox Digitas’ – about to be released
Work best when…
Work worst when…Generic, not specific Trained on a specific
conversation, especially events
Trained to make distinctions naturally present in the data (Grounded Theory
Methodology)
Longitudinal, over a long period of time
There is little iterative development with the
data
