We propose a new framework for abstractive text summarization based on a
sequence-to-sequence oriented encoder-decoder model equipped with a deep
recurrent generative decoder (DRGN).
Latent structure information implied in the target summaries is learned based
on a recurrent latent random model for improving the summarization quality.
Neural variational inference is employed to address the intractable posterior
inference for the recurrent latent variables.
Abstractive summaries are generated based on both the generative latent
variables and the discriminative deterministic states.
Extensive experiments on some benchmark datasets in different languages show
that DRGN achieves improvements over the state-of-the-art methods.

提出了一种基于序列到序列编码器 - 解码器模型并配备深层递归生成解码器的抽象文本摘要框架，通过利用循环潜在随机模型来学习目标摘要中隐含的潜在结构信息以提高摘要质量；同时应用神经变分推断来解决循环潜在变量的不可解后验推断问题，在生成潜在变量和判别性确定状态的基础上生成抽象摘要，实验结果表明，该方法优于现有最先进的方法。
