Best NLP Library 2022

Natural Language Processing is a branch of artificial intelligence designed to understand the semantics and implications of human languages. The core functionality of NLP is to collect information from text, then later use the information to train data models. Some of the NLP tasks are text mining, text analysis, text classification, word sequencing, speech recognition, and lastly synthesis.

The development of NLP has been a continuous process that has led to NLP implementation in a wide range of industries worldwide. As the system is now part of deep learning research, developing chatbots, patent research, voice & speech recognition, searching picture content, and other uses. In short, NLP is designed to make text preprocessing much simpler and easier.
