Namely, we’ll look at how rule-based systems and machine learning models work in this context. Additionally, we’ll explain how Natural Language Processing (NLP), Computer Vision, and Optical Character Recognition (OCR) are applied to document classification. What is document classification?
链接:Hierarchical Attention Networks for Document Classification 前言:本文针对文本分类任务提出了一个层次化attention机制模型(HAN),有两个显著的特点:(1)采用“词-句子-文章”的层次化结构来表示一篇文本。(2)该模型有两个层次的attention机制,分别存在于词层次(word level)和句子层次(sentence level)。从而使该模...

Document classification is one of important topics in the field of NLP(Natural Language Processing). In our previous research we've proposed a document classification method which minimizes an error rate with reference to a Bayes criterion. But when the number of documents in training data is ...
Part of NLP Collective 1 In Chapter 6 of the NLTK book, section 2.1 the code calls the movie reviews corpus for document classification. The code in the book is as follows: from nltk.corpus import movie_reviews documents = [(list(movie_reviews.words(fileid)), category) for category in...
Hierarchical Attention Networks for Document Classification 模型理解篇 最近看了HAN用在文本分类的这篇文章。提出的模型使用了分层的注意力机制,对应了文本在字词和句子两个层面的结构。也就是分别在字词层面和句子层面使用注意力机制。这样做的好处有两个:1.模型可以给与不同主要性的字词或者句子不同的关注度,最终的...

These researchers are engaged in activities ranging from natural language dialog, information retrieval, topic-tracking, named-entity detection, document classification and machine translation to bioinformatics and open-domain question answering. An analysis of these activities strongly suggested that improving...
