', 'In 2008, SpaceX’s Falcon 1 became the first privately developed \nliquid-fuel launch vehicle to orbit the Earth.'] 与执行NLP任务的其他库相比,spaCy相当快(是的,甚至是NLTK)。 5. Tokenization using Keras Keras! 目前,业界最热门的深度学习框架之一。 它是用于Python的开源神经网络库。 Keras...
它是数据进入到模型进行计算之前所必须的一个步骤;一方面,不少NLPer可能关注的往往是模型的花里胡哨,炼丹Tricks的纷繁复杂又或者是数据清洗的枯燥无味,对于字符串数据进入到模型之前所必经的Tokenization环节知之甚少;另一方面,笔者曾在工作过程中无意发现字符经过XLM-Roberta的Tokenization会多出“_”这个特殊符号,于是在...

标记器首先获取文本并将其分成更小的部分,可以是单词、单词的部分或单个字符。这些较小的文本片段被称为标记。Stanford NLP Group[2]将标记更严格地定义为: 在某些特定的文档中,作为一个有用的语义处理单元组合在一起的字符序列实例。 2、为每个标记分配一个ID ...
