                    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:

                    1.   20    5    8    15    12    15    7    25    14    3

              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. These components are called domains of AI. In this chapter, we are going to learn
              about the different domains of AI.
              Barr and Feigenbaum defined AI in 1981 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 domain of AI which helps in communication between human and computer using natural
              language. It enables a computer to read and understand data by mimicking human natural language.

              This domain of AI is used for a variety of tasks such as email filters. For example, many people receive a
              lot emails which are useless. NLP checks the sender of the email and categorises the mails as spam or
              junk. NLP is also used in the autocomplete and spell-check feature of word processors. NLP also proves
              to be quite useful with voice-to-text messaging and virtual assistants.
