In 1950, Alan Turing published his famous paper titled “ Computing Machinery and Intelligence ”. The paper proposed a test to determine if a machine was artificially intelligent. Basically, Turing said that if a machine could have a conversation with a human and trick the human into thinking the machine was a person itself, then it was artificially intelligent. While we still haven’t quite achieved , has become very popular over the past few years and is used in many products today. It’s a fascinating technology that’s already changed the tech world a lot and promises to do so even more in the future. So what makes this bit of technology so exciting? SwissCognitive

What is Natural Language Processing?

Natural language processing () can be defined as the ability of a machine to analyze, understand, and generate human . The goal of is to make interactions between computers and humans feel exactly like interactions between humans and humans. And when we say interactions between humans and humans, we’re talking about how humans communicate with each other by using natural language . Natural language is a language that is native to people. English, Spanish, French, and Mandarin are all examples of a natural language. On the other hand, computers have always operated on artificial languages (computer programming languages such as SQL, Java, C++, etc.). These languages were constructed to communicate instructions to machines.

Where do you use in your everyday life?
