Query: UnifiedSKG: Unifying and Multi-Tasking Structured Knowledge Grounding
  with Text-to-Text Language Models   Structured knowledge grounding (SKG) leverages structured knowledge to
complete user requests, such as semantic parsing over databases and question
answering over knowledge bases. Since the inputs and outputs of SKG tasks are
heterogeneous, they have been studied separately by different communities,
which limits systematic and compatible research on SKG. In this paper, we
overcome this limitation by proposing the SKG framework, which unifies 21 SKG
tasks into a text-to-text format, aiming to promote systematic SKG research,
instead of being exclusive to a single task, domain, or dataset. We use
UnifiedSKG to benchmark T5 with different sizes and show that T5, with simple
modifications when necessary, achieves state-of-the-art performance on almost
all of the 21 tasks. We further demonstrate that multi-task prefix-tuning
improves the performance on most tasks, largely improving the overall
performance. UnifiedSKG also facilitates the investigation of zero-shot and
few-shot learning, and we show that T0, GPT-3, and Codex struggle in zero-shot
and few-shot learning for SKG. We also use UnifiedSKG to conduct a series of
controlled experiments on structured knowledge encoding variants across SKG
tasks. UnifiedSKG is easily extensible to more tasks, and it is open-sourced at
