Per-fold implicit argument identification results. Columns are defined as follows: (1) fold used for testing, (2) selected features in rank order, (3) baseline F1, (4) LibLinear cost parameter, (5) LibLinear weight for the positive class, (6) implicit argument confidence threshold, (7) discriminative F1, (8) oracle F1. A bias of 1 was used for all LibLinear models. F1, (8) oracle F1. A bias of 1 was used for all LibLinear models.
