In order to enable a finer-grained understanding of metaphoricity, we instructed the annotators to employ a four-point metaphoricity scale to allow for more nuance than a simple literal/metaphoric flag.
8 annotators were asked to rate the degree of metaphoricity between the candidate source and target terms on a scale from 0 to 3, taking into consideration the context of the entire sentence (and, if available, additional paragraph-level context).
