自然语言处理NLP(nature language processing),顾名思义,就是使用计算机对语言文字进行处理的相关技术以及应用。在对文本做数据分析时,我们一大半的时间都会花在文本预处理上,而中文和英文的预处理流程稍有不同,本文就对中、英文文本挖掘的常用的NLP的文本预处技术做一个总结。 文章内容主要按下图流程讲解: 图片来自...
Cleaning and pre-processing text data is often the first and most crucial step in NLP. In this course, Text Data Cleaning and Pre-processing Techniques, you’ll gain the ability to transform raw text into a clean, structured format ready for analysis. First, you’ll explore the fundamental ...
This present paper discusses the pre-processing techniques such as tokenization, stopwords removal, POS, and parsing in machine translation. First, we take thematic divergences sentences and we do all pre-processing of these sentences. The source sentence is analyzed and finds the set of morphemes ...
Encoding context into a fixed vector using an auxiliary GNN. 由于combinatorial nature of graphs(这句话很不解,直接翻译是图的组合性质,我的理解是图的离散性质,可是 这和nlp有什么关系,难道是指节点个数不确定?),直接预测context graph是很困难的。这与自然语言处理不同,自然语言处理中,单词都是定长有限的词...
ALBERT introduces two parameter reduction techniques(介绍了两种参数缩减技术). The first one is the factorized embedding parameterization that decomposes the embedding matrix into two small matrices(1.分解嵌入参数:将嵌入矩阵分解为两个小矩阵). The second one is the cross-layer parameter sharing that the...
oov_token: the token to be used to represent words that won't be found in the word dictionary. This usually happens when processing the training data. The number 1 is usually used to represent the "out of vocabulary" token ("oov" token) ...

Foundation Models for Natural Language Processing Gerhard Paaß & Sven Giesselbach Part of the book series: Artificial Intelligence: Foundations, Theory, and Algorithms ((AIFTA)) 22k Accesses 3 Altmetric Abstract This chapter presents the main architecture types of attention-based language models,...
Recently, pre-trained models (PTMs) for representation learning [7,20], also known as foundation models [6], have become a new trend in NLP. As shown in Figs.5.1and5.2, compared with conventional representation learning techniques, the pre-training-fine-tuning paradigm of PTMs enables them ...
