with a large number of programming backgrounds than R,python, especially programmers who have mastered the Python language. So we chose the Python and NLTK libraries (natual Language Tookit) as the basic framework for text processing. In addition, we need a data display tool; For a data analyst, the database omissions installation, connection, table, etc. are not suitable for fast data analysis, so we use pandas as a structured data and analysis tool

There is a lot of text information. How do we extract useful information? For example: JSON is a good boy The expected information is JSON and a good boy. First, we need to split sentences and determine the attributes of words: You can use the followingCode: Def ie_preprocess (document ):... sentences = nltk. sent_tokenize (document )... sentences = [nltk. word_tokenize (sent) for sent in sen

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 satisfactory results, even if the stem is not t

Previously downloaded a PDF, the title is "Natural language processing with Python", very interesting, plus NLP and machine learning is hot, want to take advantage of the summer vacation to dabble. So began the journey of getting started with NLP.Installation Environment: Ubuntu14.04 Desktop version, Python version: 2.7First step: Install NLTK, first install the PIP tool: sudo apt-get install PYTHON-PIP, install with PIP after installation nltk:sudo p

The 28th page of Python natural language processing has such a command--text3.generate ()---function is to produce some random text similar to the Text3 style.errors occur when implemented with NLTK3.0.4 and Python2.7.6: ' Text ' object has no attribute ' generate '.Discover the problem after exploring:Open the NLTK folder text.py found, the original version of the NLTK did not have the "text1.generate ()"

1. Get a text corpusThe NLTK library contains a large number of corpora, which are described in the following sections:(1) Gutenberg Corpus: NLTK contains a small portion of the text of the Gutenberg project's electronic text file.
