title: Mention Types and Mention Classes in Watson Knowledge Studio
body: <p>How important are Mention Types and Mention Classes to training a machine learning annotator model? Will they get assigned automatically when entities are highlighted? For example, when you click on the Mention Type tab, “NONE” seems to be preselected. Likewise for “SPC” on the Mention Class tab. None of the videos in IBM's Watson Knowledge Studio playlist covers this aspect of using WKS and the official documentation's explanations of whether and how to properly annotate mentions with these attributes is insufficient.</p>
