A Differentiable Relaxation of Graph Segmentation and Alignment for AMR Parsing
Chunchuan Lyu, Shay B. Cohen, Ivan Titov
Abstract Meaning Representations (AMR) are a broad-coverage semantic formalism which represents sentence meaning as a directed acyclic graph. To train most AMR parsers, one needs t…
Capturing Argument Interaction in Semantic Role Labeling with Capsule Networks
Xinchi Chen, Chunchuan Lyu, Ivan Titov
Semantic role labeling (SRL) involves extracting propositions (i.e. predicates and their typed arguments) from natural language sentences. State-of-the-art SRL models rely on power…
Semantic Role Labeling with Iterative Structure Refinement
Chunchuan Lyu, Shay B. Cohen, Ivan Titov
Modern state-of-the-art Semantic Role Labeling (SRL) methods rely on expressive sentence encoders (e.g., multi-layer LSTMs) but tend to model only local (if any) interactions betwe…
AMR Parsing as Graph Prediction with Latent Alignment
Chunchuan Lyu, Ivan Titov
Abstract meaning representations (AMRs) are broad-coverage sentence-level semantic representations. AMRs represent sentences as rooted labeled directed acyclic graphs. AMR parsing…
