另外,我们的模型最终会处理大量的token:使用基于单词(word)的标记器(tokenizer),单词只会是单个标记,但当转换为字母/字(character)时,它很容易变成 10 个或更多的标记(token)。 3. Sub-word level 在实际应用中,Character level和Word level都有一些缺陷。Sub-word level是一种介于Character level和Word level之间...

The Tokenizer feature built into the smart tag infrastructure in the Microsoft Office System, which breaks down strings, punctuation, and white space into actual words for use by the recognizer, enables streams of tokens to be passed to recognizers in addition to raw text. Therefore, developers ...

Train a machine learning model to tag individual words in natural language text. Overview A word tagger is a machine learning model that’s been trained to classify natural language text at the word level. You train a word tagger by showing it multiple examples of sentences containing words you...

预处理是处理文本和构建模型以解决我们的业务问题的第一步。预处理本身是一个多阶段的过程。在本文中,我们将只讨论标记化(tokenize)和标记器(tokenizer)。 1.1 标记化(Tokenize) 标记化是文本预处理中最重要的步骤之一。无论您是使用传统 NLP 技术还是使用高级深度学习技术,都不能跳过这一步。
