tokenization 和 normalization 通常只能够正则表达式或者基于ML算法的方式来完成。
This makes it difficult to process using standard NLP techniques as these are typically trained on standard text. Text normalization is often used as a preprocessing step to overcome this problem. In this work, we take a machine translation perspective on text normalization and investigate both ...

These are other important text normalization techniques in natural language processing. However, to understand these techniques better, we have to get a bit more familiar with linguistics–the science of language. Sometimes, a word can take several forms without changing its grammatical category. These...
No need for normalization over vocabulary Overfitting to Observed Pairs 优化方案:negative sampling负采样 对于每一个c,选择k个负样本(using word probabilities),Minimize their probabilities \begin{aligned} J(\theta, c, o)= & -\log P(\text { co-occur } \mid c, o)-\log \prod_{k=1}^{K}...
重磅︱R+NLP:text2vec包——New 文本分析生态系统 No.1(一,简介) 文档可以以多种方式表达,单独词组、n-grams、特征hashing化的方法等。一般来说文本分析的步骤有以下三个步骤: 1、第一步:把内容表达成为文档-词组矩阵(document-term矩阵,DTM)或者词组共现矩阵(term-co-occurrence矩阵,TCM),换言之第一步就是...
深度学习模型在计算机视觉与语音识别方面取得了卓越的成就,在 NLP 领域也是可以的。将卷积神经网络CNN应用到文本分类任务,利用多个不同size的kernel来提取句子中的关键信息(类似 n-gram 的关键信息),从而能够更好地捕捉局部相关性。 文本分类是自然语言处理领域最活跃的研究方向之一,目前文本分类在工业界的应用场景非常...
In my experience, text normalization has even been effective for analyzinghighly unstructured clinical textswhere physicians take notes in non-standard ways. I’ve also found it useful fortopic extractionwhere near synonyms and spelling differences are common (e.g. topic modelling, topic modeling, to...
