Trainable Referring Expression Generation using Overspecification Preferences
Table 2: Referential overspecification accuracy
['Method', 'TUNA-f', 'TUNA-p', 'GRE3D3', 'GRE3D7', 'Stars', 'Stars2', 'Overall']
Given that speakers are grouped according to their overspecification preferences, it is interesting to observe whether our output descriptions actually correspond to the expected level of information. Results show that predictions made by the Profile method generally outperform those made by the Speaker method. The exception is, once again the Stars domain as discussed above.
