Casting a Wide Net: Robust Extraction of Potentially Idiomatic Expressions
Table 10: Extraction performance of the in-context-parsing-based system on each of the 25 most frequent PIE types in the corpus.
['PIE Type', 'Count', 'Precision', 'Recall', 'F1-score']
Splitting out performance per PIE type reveals whether there is indeed a large variance in performance across types. Except two cases (in the black and round the bend), we see that the performance is in the 80–100% range, even showing perfect performance on the majority of types.
