Introduction In NLP tokenizing text into sentences is a very crucial preprocessing task. Tokenization is the process of breaking the text corpus into individual sentences. In NLTK, the default tokenizer does a good task to tokenize text however it fails to do so in cases where the text contains punctuations, symbols, etc. that are non-standard. In such cases, we need to train a tokenizer. In this article let us explore the training of a tokenizer and also see the usage of filter words or stopwords. Tokenizing a Sentence in NLP The default tokenizer in NLTK can be used on the ... Read More
