Introduction
The ability to express thoughts in words (sentence generation), the ability to replace a piece of text with different but equivalent text (paraphrasing), and the ability to find the most important parts of a piece of text (summarization) are all key elements of using language. Although sentence generation, paraphrasing, and summarization are challenging tasks in NLP, there have been great strides recently that have made them considerably more accessible. In this chapter, we explore them in detail and see how we can implement them in Python.
