【新智元导读】NLP领域发展迅速，初入坑者阅读哪些论文才能快速跟上现代NLP的最新趋势？HuggingFace团队近日发布这份论文列表和资源清单，紧跟研究最前沿，必备收藏。

在过去的两年中，NLP在各种不同任务和应用上的进展十分迅速。这些进展是由于构建NLP系统的经典范式发生了转变带来的：很长一段时间以来，研究人员都使用预训练的词嵌入(如word2vec或GloVe)来初始化神经网络，然后使用一个特定于任务的架构，该架构使用单个数据集以监督方法训练。

最近，一些研究证明，我们可以利用非监督(或自监督)信号，如语言建模，在web规模的数据集上学习分层上下文表示，并将这种预训练转移到下游任务(迁移学习)。令人兴奋的是，这种转变带来了下游应用领域的重大进展，从问题回答到通过句法分析进行自然语言推理……

“我可以读哪些论文来跟上现代NLP的最新趋势?”

几周前，我的一位朋友决定入坑NLP。他已经有机器学习和深度学习的背景，所以他真诚地问我：“我可以阅读哪些论文来跟上现代NLP的最新趋势?”

这是一个非常好的问题，尤其是考虑到NLP会议(以及普遍的ML会议)收到的论文投稿呈指数级增长时：NAACL 2019收到投稿比2018增加了80%， ACL 2019收到的投稿比2018年增加了90%……

因此，我为他整理了这份论文列表和资源清单，并与大家分享。

免责声明：本列表并非详尽无遗，也无法涵盖NLP中的所有主题(例如，没有涵盖语义解析、对抗性学习、NLP强化学习等)。所选择的论文主要是过去几年/几个月最具影响力的工作。

一般而言，开始进入一个新领域的好方法是阅读介绍性或总结性的博客（比如这篇），可以让你在花时间阅读论文之前快速了解背景。
