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

By PulseAugur Editorial · [1 sources] ·

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.

IMPACT Provides insights into the limitations of specific BiLSTM architectures for dependency parsing, potentially guiding future NLP model development.

    Directional Contextual Representations for Dependency Relations: Why Cross-Direction Pairing Fails

    arXiv:2608.20647v1 Announce Type: new Abstract: Splitting a bidirectional LSTM's contextual representation into a forward-only $F_i$ (strictly a function of tokens $1..i$) and a backward-only $B_i$ (strictly a function of tokens $i..n$) beats either alone and beats a fused self-a…
