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.”
Domains of AI
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.
