Key takeaways

Text preprocessing refers to tasks and techniques we perform on raw text data before further analysis. These techniques are critical for organizations looking to uncover insights. A few examples of text preprocessing techniques include lowercasing, removing special characters and stopwords, and performing tokenization, stemming, lemmatization, and part-of-speech tagging.
