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
2. 9 20 12 14 12 9 5 7 5 20 14
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 Big Data Computer Vision
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.
