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

Well, what's happening here are our "chunked" variable are an NLTK tree. Each "chunk" and "non chunk" is a "subtree" of the tree. We can reference these by doing something like Chunked.subtrees. We can then iterate through these subtrees like so: For in chun

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
