SentiBERT: A Transferable Transformer-Based Architecture for Compositional Sentiment Semantics
Table 9: The results after incorporating token node prediction. ‘Token’ denotes token node prediction.

We observe that the results drops a bit after additionally incorporating token-level sentiment information. This may be because the phrase sentiment is composed but the token sentiment mainly depends on the meaning of the lexicon itself rather than a kind of compositional sentiment semantics. The inconsistency of the training objectives may result in the performance drop.
