Natural Language Processing with PyCaret

Natural language processing (NLP) is located at the intersection of computational linguistics and machine learning. The main goal in this dynamic field is to extract information and insights from natural languages, meaning those that are spoken by humans in their everyday lives. NLP comprises a wide variety of methods and techniques, including topic modeling, sentiment analysis, machine translation, document summarization, and speech-to-text conversion.

In this chapter, we’ll focus on topic modeling because it’s supported by the NLP module of the PyCaret library. We can use this technique to discover topics, the hidden structures that let us semantically group a collection of documents known as the corpus.
