Table to text generation with accurate content copying.

ABSTRACT: Generating fluent, coherent, and informative text from structured data is called table-to-text generation. Copying words from the table is a common method to solve the "out-of-vocabulary" problem, but it's difficult to achieve accurate copying. In order to overcome this problem, we invent an auto-regressive framework based on the transformer that combines a copying mechanism and language modeling to generate target texts. Firstly, to make the model better learn the semantic relevance between table and text, we apply a word transformation method, which incorporates the field and position information into the target text to acquire the position of where to copy. Then we propose two auxiliary learning objectives, namely table-text constraint loss and copy loss. Table-text constraint loss is u
