Negation-Instance Based Evaluation of End-to-End Negation Resolution

Understand

In this paper, we revisit the task of negation resolution, which includes the subtasks of cue detection (e.g.

• "not", "never") and scope resolution.
• In the context of previous shared tasks, a variety of evaluation metrics have been proposed.
• Subsequent works usually use different subsets of these, including variations and custom implementations, rendering meaningful comparisons between systems difficult.
