Abstract
Hierarchical context tagging for utterance rewriting comprising computer code for obtaining source tokens and context tokens, encoding the source tokens and the context tokens to generate source contextualized embeddings and context contextualized embeddings, tagging the source tokens with tags indicating a keep or delete action for each source token of the source tokens, selecting a rule to insert before the each source token, wherein the rule contains a sequence of one or more slots, and generating spans from the context tokens, wherein each span corresponds to one of the one or more slots of the selected rule.
