To assess the performance of the approach the
model produced for each verb was tested on the
corresponding set of test cases by applying the
rules in a decision-list like approach, i.e., retaining ... context. For example, among the
possible senses of the verb “run” are “to move fast
by using one's feet” and “to direct or control”.
