Natural Language Processing (NLP) is a branch of artificial intelligence that focuses on understanding and manipulating human language through computers. It encompasses a set of techniques aimed at enabling machines to comprehend, interpret, and generate natural language, such as that used by humans in written and spoken communication.

The term “Natural Language Processing” was first introduced by Yehoshua Bar-Hillel, an Israeli linguist and philosopher, in the 1950s. Since then, this discipline has evolved to include areas such as speech recognition, machine translation, sentiment analysis, and other applications related to machines understanding natural language.


Early efforts in NLP were focused on developing machine translation systems, such as the Georgetown-IBM experiment in 1954, which aimed to automatically translate Russian sentences into English.

Since then, NLP has seen significant advancements and applications across various domains in the computer industry. Over the years, it has become an integral part of many technologies, including speech recognition, text generation, sentiment analysis, chatbots, and language translation systems. The ongoing development of NLP techniques has played a crucial role in enhancing human-computer interaction and enabling machines to understand and process natural language more effectively.
