A survey of cross-lingual features for zero-shot cross-lingual semantic parsing
Table 3: Error analysis.
['[EMPTY]', 'German P', 'German R', 'German F', 'Italian P', 'Italian R', 'Italian F', 'Dutch P', 'Dutch R', 'Dutch F']
We perform an error analysis to assess the quality of the prediction for operators (i.e. logic operators like “Not” as well as discourse relations “Contrast”), non-lexical predicates, such as binary predicates (e.g. Agent(e,x)) as well as unary predicates (e.g. time(t), entity(x), etc.), as well as for lexical predicates (e.g. open(e)). Prediction of lexical predicates is relatively good even though most tokens in the test set where never seen during training; this can be attributable to the copy mechanism that is able to transfer tokens from the input directly during predication.
