Researchers have developed TagInsert, a novel Transformer-based model that deviates from the standard left-to-right generation approach for sequence labeling tasks. By removing the decoder-side attention mask, TagInsert allows the model to dynamically determine the optimal order for generating tags during inference. Experiments on Part-of-Speech tagging and Combinatory Categorial Grammar supertagging across various languages and low-resource settings demonstrate that TagInsert often surpasses left-to-right encoder-decoder models and performs comparably to encoder-only models like BERT in data-scarce environments. The model's ability to defer challenging predictions to later stages helps mitigate error propagation common in autoregressive models. AI
