By comparing the dynamic cache model using correct zero-anaphora resolution (denoted by DCM (with ZAR) in Figure 4) and the one without it (DCM (w/o ZAR)), we can see that correct zeroanaphora resolution contributes to improving the caching for every cache size.
in the practical setting the current zero-anaphora resolu-tion system sometimes chooses the wrong candidate as an antecedent or does not choose any candidate due to wrong anaphoricity determination, negatively impacting the performance of the cache model.
