[Python + nltk] Brief Introduction to natural language processing and NLTK environment configuration and introduction (I)1. Introduction to Natural Language Processing The so-called "Natural Language" refers to the language used for daily communication, such as English and Hindi. It is difficult to use clear rules to portray it as it evolves.In a broad sense, "Na

product comment corpus in nltk, but only in English. But the entire idea can be consistent ). There is also a Chinese Python encoding problem that troubles many people. I have summarized some experiences after multiple failures. Python can use the following logic to solve Chinese Encoding Problems: Utf8 (input) --> unicode (processing) --> (output) utf8 All cha

the following logic:UTF8 (input)--Unicode (processing)--(output) UTF8The characters processed in Python are all Unicode encodings, so the solution to the coding problem is to decode the input text (whatever encoding) into the (decode) Unicode encoding, and then encode (encode) the encoding when it is output.Because the process is generally txt document, the simplest way is to save the TXT document as Utf-8 encoding, and then use

This is the first I have done the installation NLTK, the installation was successful. At that time, remember to refer to this post: Http://www.tuicool.com/articles/VFf6BzaWherein, NLTK installation, encountered the module was not found, followed by the prompt corresponding to download four or five modules, only successfully installed. Later, the corpus is also installed offline.1. Install

In Python, The NLTK library is used to extract the stem. What is stem extraction? In terms of linguistic morphology and information retrieval, stem extraction is the process of removing suffixes to obtain the root word-the most common way to get words. For the morphological root of a word, the stem does not need to be exactly the same; the corresponding ing of the word to the same stem generally produces sa

This article mainly introduces how to use the NLTK Library in Python to extract stem words. Pandas and IPython are also used. For more information, see What is stem extraction? In terms of linguistic morphology and information retrieval, stem extraction is the process of removing suffixes to obtain the root word-the most common way to get words. For the morphological root of a word, the stem does not need
