在分析英文文本时,我们可能会关心文本当中每个词语的词性和在句中起到的作用.识别文本中各个单词词性的过程,可以称为词性标注. 英语主要的八种词性分别为: 1.名词(noun) 2.代词(pronoun) 3.动词(verb) 4.形容词(adjective) 5.副词(adverb) 6.介词(preposition) 7.连词(conjunction) 8.感叹词(interjection) 其他还包括数词(numeral)和冠词(article)等. 在使用第三方工具(如NLTK)进行词性标注

NLP中常用的PTB语料库,全名Penn Treebank.Penn Treebank是一个项目的名称,项目目的是对语料进行标注,标注内容包括词性标注以及句法分析. 语料来源为:1989年华尔街日报语料规模:1M words,2499篇文章语料价格:1500 ~ 1700$ Penn Treebank委托Linguistic Data Consortium (LDC) 发行与收费,这意味着你想下载PTB就要去LDC的网站上下载(https://www.ldc.upenn.edu/).PTB有两个

NLTK和SpaCy是NLP的Python应用,提供了一些现成的处理工具和数据接口.下面介绍它们的一些常用功能和特性,便于对NLP研究的组成形式有一个基本的了解. NLTK Natural Language Toolkit (NLTK) 由宾夕法尼亚大学开发,提供了超过50种语料库,以及一些常用的文本处理函数,例如分词(Tokenization).词干(Stemming).词性标记(Tagging)等. 下面主要介绍WordNet语料库,其它方法和接口等用到了再进行记录. WordNet 在Wo

最近,笔者想研究BERT模型,然而发现想弄懂BERT模型,还得先了解Transformer. 本文尽量贴合Transformer的原论文,但考虑到要易于理解,所以并非逐句翻译,而是根据笔者的个人理解进行翻译,其中有一些论文没有解释清楚或者笔者未能深入理解的地方,都有放出原文,如有不当之处,请各位多多包含,并希望得到指导和纠正. 论文标题 Attention Is ALL You Need 论文地址 https://arxiv.org/pdf/1706.03762.pdf 摘要 序列转换方式由基于

Abstract We introduce a new type of deep contextualized word representation that models both (1) complex characteristics of word use (eg, syntax and semantics), and (2) how these uses vary across linguistic contexts (i.e. to model polysemy). 我们引入了一种新

微调BERT:序列级和令牌级应用程序 Fine-Tuning BERT for Sequence-Level and Token-Level Applications 为自然语言处理应用程序设计了不同的模型,例如基于RNNs.CNNs.attention和MLPs.当存在空间或时间限制时,这些模型是有用的,然而,为每个自然语言处理任务构建一个特定的模型实际上是不可行的.介绍了一个预训练模型,BERT,要求对各种自然语言处理任务进行最小的体系结构更改.一方面,在提出这个建议的时候,BERT改进了各

随着TensorFlow发布的,还有一个models库(仓库地址:https://github.com/tensorflow/models),里面包含官方及社群所发布的一些基于TensorFlow实现的模型库,用于解决各式各样的机器学习问题. 很多任务,在其中都能找到相同或者近似功能的实现,这时候无需编程或者只要很少的编程,就可以在已有模型的基础上建立自己的人工智能应用. 而且models的更新也比较快,因为大量的社群参与者,几乎每天都有模块的更新commit. 简介 当前版本TensorFlo
