For example, th… from nltk.tokenize import sent_tokenize, word_tokenize text = "Natural language processing (NLP) is a field " + \ "of computer science, artificial intelligence " + \ You can Then this is the tip you are looking for. Japanese is written without spaces, and deciding where one word ends and another begins is not trivial. You are trying to parse data with a fixed number of fields, where each field maps to a specific record in a structure or table in your application. This is typically in kanji even if the word isn't usually StreamTokenizer provides similar functionality but the tokenization method is much simpler than the one used by the StreamTokenizer class. When the parameter gaps=True is added, the matching pattern will be used as the separators. Yes No 2 out of 2 found this helpful Have more questions?
