一、文本数据预处理基本步骤(text dataset pre-processing) 1. 去除非文本部分 现象: HTML标签、表情符号 解决工具: regular expression、beautifulsoup 2. 拼写检查更正 现象: "I am verry happy" 解决工具: textblob 3. 分词 segmenting sentences in text: nltk.sent_tokenize() segmenting/tokenizing words in...
Tokenization is the first step in NLP. It is the process of breaking strings into tokens which in turn are small structures or units. Tokenization involves three steps which are breaking a complex sentence into words, understanding the importance of each word with respect to the sentence and fin...
Text mining—also called text data mining—is an advanced discipline within data science that usesnatural language processing (NLP),artificial intelligence (AI)andmachine learningmodels, and data mining techniques to derive pertinent qualitative information fromunstructured text data. Text analysis takes it...
Deep learning has improved machine translation and other natural language processing tasks by leaps and bounds
1.简介 目标：基于pytorch、transformers做中文领域的nlp开箱即用的训练框架，提供全套的训练、微调模型（包括大模型、文本转向量、文本生成、多模态等模型）的解决方案；数据：从开源社区，整理了海量的训练数据，帮助用户可以快速上手；同时也开放训练数据模版，可以快速处理垂直领域数据；结合多线程、内存映射等更高效的...
Repeat the above steps until a particular word is generated, which means that the text generation can be stopped for this time. In the example, the text is complete when the word "[EOS]" is generated. 2. 解决的问题(Problem) 由于这种模型生成文本的方式是一个词一个词的输出,所以它是否能够...
Natural language processing (NLP) tools can facilitate the extraction of biomedical concepts from unstructured free texts, such as research articles or clinical notes. The NLP software tools CLAMP, cTAKES, and MetaMap are among the most widely used tools

In Chapter 2, we discussed some of the common NLP pipelines. The text classification pipeline shares some of its steps with the pipelines we learned in that chapter. One typically follows these steps when building a text classification system: Collect or create a labeled dataset suitable for the...
The invention discloses a method for processing text. According to the invention, by expansion of the conventional object coreference technology, automatic, comprehensive, accurate and effective analysis and processing of text data is realized. The method comprises the following steps of: acquiring text...
