  We follow the step-by-step approach to neural data-to-text generation we
proposed in Moryossef et al (2019), in which the generation process is divided
into a text-planning stage followed by a plan-realization stage. We suggest
four extensions to that framework: (1) we introduce a trainable neural planning
component that can generate effective plans several orders of magnitude faster
than the original planner; (2) we incorporate typing hints that improve the
model's ability to deal with unseen relations and entities; (3) we introduce a
verification-by-reranking stage that substantially improves the faithfulness of
the resulting texts; (4) we incorporate a simple but effective referring
expression generation module. These extensions result in a generation process
that is faster, more fluent, and more accurate.
