GLUE基准数据集介绍及下载
一、简介
自然语言处理（NLP）主要自然语言理解（NLU）和自然语言生成（NLG）。为了让NLU任务发挥最大的作用，来自纽约大学、华盛顿大学等机构创建了一个多任务的自然语言理解基准和分析平台，也就是GLUE（General Language Understanding Evaluation）。
GLUE包含九项NLU任务，语言均为英语。GLUE九项任务涉及到自然语言推断、文本蕴含、情感分析、语义相似等多个任务。像BERT、XLNet、RoBERTa、ERINE、T5等知名模型都会在此基准上进行测试。目前，大家要把预测结果上传到官方的网站上，官方会给出测试的结果。
GLUE的论文为：GLUE: A Multi-Task Benchmark and Analysis Platform for Natural Language Understanding[1]
GLUE的官网为：https://gluebenchmark.com/
本文的目的在于针对GLUE的九个任务分别做一个相对详细的说明，给出一些样例，有一个相对整体确切的感受，同时提供一个可以方便下载GLUE数据集的链接，供读者使用。
二、任务介绍
GLUE共有九个任务，分别是CoLA、SST-2、MRPC、STS-B、QQP、MNLI、QNLI、RTE、WNLI。如下图图2所示，可以分为三类，分别是单句任务，相似性和释义任务，
图2：GLUE九大任务的描述和统计。所有任务都是单句或者句子对分类，除了STS-B是一个回归任务。MNLI有3个类别，所有其他分类任务都是2个类别。测试集中加粗的表示测试集中标签从未在公共论坛等场所展示过
2.1 CoLA
CoLA(The Corpus of Linguistic Acceptability，语言可接受性语料库)，单句子分类任务，语料来自语言理论的书籍和期刊，每个句子被标注为是否合乎语法的单词序列。本任务是一个二分类任务，标签共两个，分别是0和1，其中0表示不合乎语法，1表示合乎语法。
样本个数：训练集8, 551个，开发集1, 043个，测试集1, 063个。
任务：可接受程度，合乎语法与不合乎语法二分类。
评价准则：Matthews correlation coefficient。
标签为1（合乎语法）的样例：
She is proud.
she is the mother.
John thinks Mary left.
Yes, she did.
Will John not go to school?
Mary noticed John's excessive appreciation of himself.
标签为0（不合语法）的样例：
Mary sent.
Yes, she used.
Mary wonders for Bill to come.
They are intense of Bill.
Mary thinks whether Bill will come.
Mary noticed John's excessive appreciation of herself.
注意到，这里面的句子看起来不是很长，有些错误是性别不符，有些是缺词、少词，有些是加s不加s的情况，各种语法错误。但我也注意到，有一些看起来错误并没有那么严重，甚至在某些情况还是可以说的通的。
2.2 SST-2
SST-2(The Stanford Sentiment Treebank，斯坦福情感树库)，单句子分类任务，包含电影评论中的句子和它们情感的人类注释。这项任务是给定句子的情感，类别分为两类正面情感（positive，样本标签对应为1）和负面情感（negative，样本标签对应为0），并且只用句子级别的标签。也就是，本任务也是一个二分类任务，针对句子级别，分为正面和负面情感。
样本个数：训练集67, 350个，开发集873个，测试集1, 821个。
任务：情感分类，正面情感和负面情感二分类。
评价准则：accuracy。
标签为1（正面情感，positive）的样例：
two central performances
against shimmering cinematography that lends the setting the ethereal beauty of an asian landscape painting
the situation in a well-balanced fashion
a better movie
at achieving the modest , crowd-pleasing goals it sets for itself
a patient viewer
标签为0（负面情感，negative）的样例：
a transparently hypocritical work that feels as though it 's trying to set the women 's liberation movement back 20 years
so pat it makes your teeth hurt
blood work is laughable in the solemnity with which it tries to pump life into overworked elements from eastwood 's dirty harry period .
faced with the possibility that her life is meaningless , vapid and devoid of substance , in a movie that is definitely meaningless , vapid and devoid of substance
monotone
this new jangle of noise , mayhem and stupidity must be a serious contender for the title .
注意到，由于句子来源于电影评论，又有它们情感的人类注释，不同于CoLA的整体偏短，有些句子很长，有些句子很短，长短并不整齐划一。
2.3 MRPC
MRPC(The Microsoft Research Paraphrase Corpus，微软研究院释义语料库)，相似性和释义任务，是从在线新闻源中自动抽取句子对语料库，并人工注释句子对中的句子是否在语义上等效。类别并不平衡，其中68%的正样本，所以遵循常规的做法，报告准确率（accuracy）和F1值。
样本个数：训练集3, 668个，开发集408个，测试集1, 725个。
任务：是否释义二分类，是释义，不是释义两类。
评价准则：准确率（accuracy）和F1值。
标签为1（正样本，互为释义）的样例（每个样例是两句话，中间用tab隔开）：
The largest gains were seen in prices , new orders , inventories and exports . Sub-indexes measuring prices , new orders , inventories and exports increased .

标签为0（负样本，不互为释义）的样例：

本任务的数据集，包含两句话，每个样本的句子长度都非常长，且数据不均衡，正样本占比68%，负样本仅占32%。
2.4 STSB
STSB(The Semantic Textual Similarity Benchmark，语义文本相似性基准测试)，相似性和释义任务，是从新闻标题、视频标题、图像标题以及自然语言推断数据中提取的句子对的集合，每对都是由人类注释的，其相似性评分为0-5(大于等于0且小于等于5的浮点数，原始paper里写的是1-5，可能是作者失误）。任务就是预测这些相似性得分，本质上是一个回归问题，但是依然可以用分类的方法，可以归类为句子对的文本五分类任务。
样本个数：训练集5, 749个，开发集1, 379个，测试集1, 377个。
任务：回归任务，预测为1-5之间的相似性得分的浮点数。但是依然可以使用分类的方法，作为五分类。
评价准则：Pearson and Spearman correlation coefficients。
一些训练集中的样例句子对及其得分：
A plane is taking off. An air plane is taking off. 5.000
A man is playing a large flute. A man is playing a flute. 3.800
A dog rides a skateboard. A dog is riding a skateboard. 5.000

Someone is slicing tortila's. Someone is riding a horse. 0.000
A man is playing the guitar. A man plays an acoustic guitar. 3.750
整体句子长度适中偏短，且均衡。
2.5 QQP
QQP(The Quora Question Pairs, Quora问题对数集)，相似性和释义任务，是社区问答网站Quora中问题对的集合。任务是确定一对问题在语义上是否等效。与MRPC一样，QQP也是正负样本不均衡的，不同是的QQP负样本占63%，正样本是37%，所以我们也是报告准确率和F1值。我们使用标准测试集，为此我们从作者那里获得了专用标签。我们观察到测试集与训练集分布不同。
样本个数：训练集363, 870个，开发集40, 431个，测试集390, 965个。
任务：判定句子对是否等效，等效、不等效两种情况，二分类任务。
评价准则：准确率（accuracy）和F1值。
标签为1（正样本，互为释义，等效）的样例（每个样例是两句话，中间用tab隔开）：

类似于MRPC，句子对的释义问题。这里突出的除了样本不均衡、训练集测试集分布不一致外，还有这个训练集、测试集都非常大。这里的测试集比其他训练集都要多好几倍。
2.6 MNLI
MNLI(The Multi-Genre Natural Language Inference Corpus, 多类型自然语言推理数据库)，自然语言推断任务，是通过众包方式对句子对进行文本蕴含标注的集合。给定前提（premise）语句和假设（hypothesis）语句，任务是预测前提语句是否包含假设（蕴含, entailment），与假设矛盾（矛盾，contradiction）或者两者都不（中立，neutral）。前提语句是从数十种不同来源收集的，包括转录的语音，小说和政府报告。
样本个数：训练集392, 702个，开发集dev-matched 9, 815个，开发集dev-mismatched9, 832个，测试集test-matched 9, 796个，测试集test-dismatched9, 847个。因为MNLI是集合了许多不同领域风格的文本，所以又分为了matched和mismatched两个版本的数据集，matched指的是训练集和测试集的数据来源一致，mismached指的是训练集和测试集来源不一致。
任务：句子对，一个前提，一个是假设。前提和假设的关系有三种情况：蕴含（entailment），矛盾（contradiction），中立（neutral）。句子对三分类问题。
评价准则：matched accuracy/mismatched accuracy。
标签为蕴含（entailment）的句子对示例：

总体训练集很充足，GLUE论文作者使用并推荐SNLI数据集[2]作为辅助训练数据。
2.7 QNLI
QNLI(Qusetion-answering NLI，问答自然语言推断)，自然语言推断任务。QNLI是从另一个数据集The Stanford Question Answering Dataset(斯坦福问答数据集, SQuAD 1.0)[3]转换而来的。SQuAD 1.0是有一个问题-段落对组成的问答数据集，其中段落来自维基百科，段落中的一个句子包含问题的答案。这里可以看到有个要素，来自维基百科的段落，问题，段落中的一个句子包含问题的答案。通过将问题和上下文（即维基百科段落）中的每一句话进行组合，并过滤掉词汇重叠比较低的句子对就得到了QNLI中的句子对。相比原始SQuAD任务，消除了模型选择准确答案的要求；也消除了简化的假设，即答案适中在输入中并且词汇重叠是可靠的提示。
样本个数：训练集104, 743个，开发集5, 463个，测试集5, 461个。
任务：判断问题（question）和句子（sentence，维基百科段落中的一句）是否蕴含，蕴含和不蕴含，二分类。
评价准则：准确率（accuracy）。
标签为蕴含（entailment，正样本）的样例（每个样例是两句话，中间用tab隔开，第一句是问题，第二句是上下文中的一句）：

总体就是问答句子组成的问答对，一个是问题，一个是句子信息，后者包含前者的答案就是蕴含，不包含就是不蕴含，是一个二分类。
2.8 RTE
RTE(The Recognizing Textual Entailment datasets，识别文本蕴含数据集)，自然语言推断任务，它是将一系列的年度文本蕴含挑战赛的数据集进行整合合并而来的，包含RTE1[4]，RTE2，RTE3[5]，RTE5等，这些数据样本都从新闻和维基百科构建而来。将这些所有数据转换为二分类，对于三分类的数据，为了保持一致性，将中立（neutral）和矛盾（contradiction）转换为不蕴含（not entailment）。
样本个数：训练集2, 491个，开发集277个，测试集3, 000个。
任务：判断句子对是否蕴含，句子1和句子2是否互为蕴含，二分类任务。

She is charged with disorderly intoxication and resisting arrest. Sierra once reached the finals of "American Idol".

It specifically stated that "Saturday 10th and Sunday 11th, Indonesian waters would have witnessed storm force waves," but despite the dire warnings KM Teratai set for the seas. An Indonesian ferry with 300 passengers sank.
2.9 WNLI
WNLI(Winograd NLI，Winograd自然语言推断)，自然语言推断任务，数据集来自于竞赛数据的转换。Winograd Schema Challenge[6]，该竞赛是一项阅读理解任务，其中系统必须读一个带有代词的句子，并从列表中找到代词的指代对象。这些样本都是都是手动创建的，以挫败简单的统计方法：每个样本都取决于句子中单个单词或短语提供的上下文信息。为了将问题转换成句子对分类，方法是通过用每个可能的列表中的每个可能的指代去替换原始句子中的代词。任务是预测两个句子对是否有关（蕴含、不蕴含）。训练集两个类别是均衡的，测试集是不均衡的，65%是不蕴含。
样本个数：训练集635个，开发集71个，测试集146个。
任务：判断句子对是否相关，蕴含和不蕴含，二分类任务。
评价准则：准确率（accuracy）。
