TEES 2.2: Biomedical Event Extraction for Diverse Corpora

Table 4 System component performance in F-score evaluated by replacing individual processing steps with an "All Correct" classifier that always returns the correct result.

All Correct	Simple	Binding	Regulation	All
None	76.87	50.44	42.87	55.99
Entity	93.17	65.72	65.37	75.32
Edge	89.70	71.63	72.46	78.62
Unmerging	86.53	77.30	61.07	72.76
Entity + Edge	98.40	77.99	93.38	93.32
All	98.40	94.63	94.75	95.99

The left column shows the step or steps replaced. The other columns show performance for GE11 event subsets, where Simple refers to the five single-argument event types and Regulation to the three regulation types. Performance is evaluated for task 1 on the development set with the downloadable GE11 evaluator.
