| Challenge: | Structured representations for task-oriented assistant systems are limited due to the limitations of the representation. |
| Approach: | They propose a semantic representation for task-oriented conversational systems that can represent co-reference and context carryover. |
| Outcome: | The proposed model improves the best results on ATIS, SNIPS, TOP and DSTC2 by up to 5 points for slot-carryover. |
Sound Natural: Content Rephrasing in Dialog Systems (2020.emnlp-main)
Copied to clipboard
| Challenge: | Currently, virtual assistants work in the paradigm of intent-slot tagging and the slot values are directly passed as-is to the execution engine. |
| Approach: | They propose to use BART to rephrase a query to make it more natural . they propose to add a copy-pointer and copy loss to it to improve performance . |
| Outcome: | The proposed model improves on existing models by adding a copy-pointer and copy loss. |
