Twitter-aware tokenizer, designed to be flexible and easy to adapt to new domains and tasks. The basic logic is this: The tuple REGEXPS defines a list of regular expression strings. The REGEXPS strings are put, in order, into a compiled regular expression object called WORD_RE, under the TweetTokenizer class.a: nltk.app nltk.app.chartparser_app nltk.app.chunkparser_app nltk.app.collocations_app nltk.app.concordance_app ...>>> from nltk.tokenize.treebank import TreebankWordDetokenizer >>> detokenizer = TreebankWordDetokenizer >>> s = "On a $50,000 mortgage of 30 years at 8 percent, the monthly payment would be $366.88."Regular-Expression Tokenizers. A RegexpTokenizer splits a string into substrings using a regular expression. For example, the following tokenizer forms tokens out of alphabetic sequences, money expressions, and any other non-whitespace sequences: >>> from nltk.tokenize import RegexpTokenizer >>> s = "Good muffins cost $3.88\nin …NLTK 3.8 release: December 2022: Fix WordNet’s all_synsets () function.
