Research paper questions cross-direction pairing in BiLSTM dependency relation classification

A new research paper explores the effectiveness of directional contextual representations in dependency relation classification. The study, focusing on BiLSTM models, found that splitting representations into forward-only and backward-only components outperforms either alone or fused self-attention. However, a specific cross-direction pairing method, where a token's forward state is compared against a candidate's backward state, consistently underperformed same-direction pairing, with the performance gap widening with token distance.
