Three aspects of NLP analysis Technology NLP Analysis technology is divided into three levels: lexical analysis, syntactic analysis and semantic analysis. 1 Lexical analysis includes word segmentation, POS tagging, named entity recognition and Word sense disambiguation. Participle and part of speech to mark good understanding. The task of named entity recognition is to identify named entities, such as n

Preface: Natural Language Processing (NLP) is widely used in speech recognition, machine translation, and automatic Q . The early natural language processing technology was based on "part of speech" and "Syntax". By the end of 1970s, it was replaced by the "Mathematical Statistics" method. For more information about NLP history, see the book the beauty of mathematics. This series follows Professor Stanford

Figure 1 shows a typical network structure that uses the CNN model in NLP tasks. In general, the input word or word is expressed in Word embedding, so that a one-dimensional text information input is converted into a two-dimensional input structure, assuming that the input x contai

Since it was proposed, GAN has been widely paid attention to, especially in the field of computer vision caused a lot of repercussions. "Deep interpretation: Gan model and its progress in the 2016" [1] A detailed introduction to the progress of Gan in the past year, very recommended to learn from the beginners of Gan read. This article mainly introduces the application of Gan in NLP (which can be regarded as paper interpretation or paper notes), does
