**ERNIE-Doc is a document-level language pretraining model**. Two well-designed techniques, namely the **retrospective feed mechanism** and the **enhanced recurrence mechanism**, enable ERNIE-Doc, which has a much longer effective context length, to capture the contextual information of a complete document. ERNIE-Doc improved the state-of-the-art language modeling result of perplexity to 16.8 on WikiText-103. Moreover, it outperformed competitive pretraining models by a large margin on most language understanding tasks, such as text classification, question answering, information extraction and semantic matching.
## Framework
We proposed three novel methods to enhance the long document modeling ability of Transformers:
- **Retrospective Feed Mechanism**: Inspired by the human reading behavior of skimming a document first and then looking back upon it attentively, we design a retrospective feed mechanism in which segments from a document are fed twice as input. As a result, each segment in the retrospective phase could explicitly fuse the semantic information of the entire document learned in the skimming phase, which prevents context fragmentation.
- **Enhanced Recurrence Mechansim**, a drop-in replacement for a Recurrence Transformer (like Transformer-XL), by changing the shifting-one-layer-downwards recurrence to the same-layer recurrence. In this manner, the maximum effective context length can be expanded, and past higher-level representations can be exploited to enrich future lower-level representations.
- **Segment-reordering Objective**, a document-aware task of predicting the correct order of the permuted set of segments of a document, to model the relationship among segments directly. This allows ERNIE-Doc to build full document representations for prediction.

## Pre-trained Models
We release the checkpoints for **ERNIE-Doc _base_en/zh_** and **ERNIE-Doc _large_en_** model。

**ERNIE-Doc 是面向篇章级长文本建模的预训练-微调框架**，ERNIE-Doc 受到人类先粗读后精读的阅读方式启发，提出了**回顾式建模机制**和**增强记忆机制**，突破了 Transformer 在文本长度上的建模瓶颈。ERNIE-Doc 在业界首次实现了全篇章级无限长文本的双向建模，在包括阅读理解、信息抽取、篇章分类、语言模型在内的13个权威中英文长文本语言理解任务上取得了SOTA效果。
## 模型框架
我们提出了三种方法解决长文本建模问题:
- **回顾式建模机制（Retrospective Feed Mechanism）**: 通过将文本片段重复输入两次，使得在回顾阶段的每一个文本片段可以双向建模并利用在粗读阶段获取到的全篇章语义信息。
- **增强记忆机制（Enhanced Recurrence Mechansim）**: 通过改进Recurrence Transformer模型（Transformer-XL等）为同层循环的方式，可建模无限长文本。
- **段落重排序目标（Segment-reordering Objective）**: 该预训练目标通过让模型学习篇章级本文段落间的关系，使得模型可以对篇章整体信息进行建模。
下图展示了ERNIE-Doc 与Recurrence Transformer在3层网络，4个片段输入情况下的建模方式与建模长度的对比。

## 预训练模型
我们发布了 **ERNIE-Doc _base_** 中英文模型和 **ERNIE-Doc _large_** 英文模型。

## 下游任务
我们在语言建模、篇章级分类、阅读理解以及信息抽取等任务上选取了广泛使用的数据集进行模型效果验证，并且与当前效果最优的模型（[Longformer](https://arxiv.org/abs/2004.05150)、[BigBird](https://arxiv.org/abs/2007.14062)、[ETC](https://arxiv.org/abs/2004.08483)、[ERNIE2.0](https://arxiv.org/abs/1907.12412)等）进行对比。
