Using a built-in dataset; Using a custom tokenizer; Using pretrained word embeddings. 使用torchtext加载文本数据 本节主要是用的模块是 torchtext 里的 data 模块,处理的数据同上一节所描述。 首先定义一个 tokenizer 用来处理文本,比如分词,小写化,如果你已经根据上一节的词干提取和词型还原的方法处理过文本里的每一个单词后可以直接分词就够. We compose a sequence of transformation to pre-process the image: Compose creates a series of transformation to prepare the dataset. Please cite the paper, if you use this corpus in your work. This notebook classifies movie reviews as positive or negative using the text of the review. The few systems that are more accurate are 20× slower or more. load( 'de') spacy_en = spacy. If you leave this blank, no sorting will happen (I could be wrong, but on my simple “experiment”, it seems to be the case). The torchtext. It can be applied to movie reviews, feedback of other forms, emails, tweets, and even course evaluations.
