              A robot has been developed which can quickly replace a number with the English letter at its
              position. From the letters obtained, the robot can form a meaningful word by rearranging the letters.
              Aditi has provided following numeric codes to the robot. See, if you can compete with the robot and
              make meaningful words from these codes:

        We all are aware of the fact that every machine or organism is made of smaller parts that perform a
        specific type of task. Similarly, the AI system is also built from different smaller mechanisms that help
        the AI to work properly. These working mechanisms are the different components with which the AI
        system can work. They are commonly called domains of AI. In this chapter, we are going to learn about
        the different domains of AI.
        Barr and Feigenbaum in 1981 defined AI as “Artificial Intelligence (AI) is the part of computer science
        concerned with  designing intelligent computer systems, that is, systems that exhibit  characteristics we
        associate with intelligence in human behaviour—understanding language, learning, reasoning, solving
        problems, and so on.”

        There are different approaches or domains to achieve Artificial Intelligence. There are various methods

        through which we can develop artificially intelligent systems. Let us learn about these domains.

             NATURAL LANGUAGE PROCESSING (NLP)

        This is a subfield of AI which helps in communication between human and computer in natural language.
        It enables a computer to read and understand data by mimicking human natural language.

        This subfield of AI is used for a variety of tasks such as email filters. A lot of people receive a lot emails
        which are useless. NLP checks the sender of the email and categorises the mails as spam or junk. NLP
        also finds its use in the auto complete and spell check feature of word processors. NLP also proves to
        be quite useful in voice text messaging and virtual assistants.
