Natural Language Processing (NLP) is a subfield of artificial intelligence that focuses on enabling computers to understand, interpret, and generate human language. NLP tools and libraries play a crucial role in simplifying the development of NLP applications, improving efficiency, and providing out-of-the-box solutions for common tasks. In this article, we will discuss some of the most popular NLP tools and libraries, their features, and the corresponding references to help you explore them further.
spaCy is a popular open-source Python library for advanced NLP tasks, developed by Explosion AI. It is designed for production use, offering high-performance capabilities and ease of use. spaCy supports various tasks such as tokenization, part-of-speech tagging, named entity recognition, and dependency parsing (Honnibal & Montani, 2021).

The Natural Language Toolkit (NLTK) is a powerful Python library for working with human language data. It provides a comprehensive suite of tools for text processing, classification, tokenization, stemming, tagging, and parsing. NLTK is widely used in academia and research, offering a vast range of resources and algorithms for linguistic analysis (Bird, Loper & Klein, 2009).
