This task was the classical Word-Sense-Disambiguation task:  for each KWIC the annotators assigned the ID of the best-fitting PDEV pattern, with the options to say that no pattern was really fitting (unclassified) or that the keyword was not a verb (not verb) and therefore the verbal patterns were all irrelevant. In addition, the annotators could specify their reservations with respect to the syntactic definition of the PDEV pattern, the Semantic Types, or diagnose a meaning shift.
