Introduction:
Today the massive and rapid advancement of technology is infuencing every aspect of human life greatly.
Artificial intelligence is a modern discovery of computer and information technology and this sector tends to bring
anout a grat revolution in human life in the coming days.The subject of Artificial Intelligence has many fields such as:
Optical character recognition,Handwriting recognition,Speech recognition,Face recognition, bots etc. Internet bot is one
of the most amazing and interesting invention of AI.
What is AI? :
Artificial intelligence, defined as intelligence delivered to machines, has many applications in today's society.
More specifically, it is Weak AI, the form of A.I. where programs are developed to perform specific tasks, that is
being utilized for a wide range of activities including medical diagnosis, electronic trading, robot control, and
remote sensing. AI has been used to develop and advance numerous fields and industries, including finance, healthcare,
education, transportation, and more.
What is Internet Bot?:
An Internet Bot, also known as web robot, WWW robot or simply -bot-, is a software application that runs automated
tasks (scripts) over the Internet. Typically, bots perform tasks that are both simple and structurally repetitive,
at a much higher rate than would be possible for a human alone. The largest use of bots is in web spidering
(web crawler), in which an automated script fetches, analyzes and files information from web servers at many times the
speed of a human. More than half of all web traffic is made up of bots.
Cleverbot:
Cleverbot is one of the oldest chatterbots discovered in Britain in 1988. Unlike some other chatterbots, Cleverbot's
responses are not programmed before the operation.It rather learns from human input: Humans type into the box below
the Cleverbot logo and the system finds all keywords or an exact phrase matching the input. After searching through its saved
conversations, it responds to the input by finding how a human responded to that input when it was asked,
in part or in full, by Cleverbot. It can read human's mind very effectively and surprisingly.This bot is able to produce heuristic results.
Having conversation with a particular person it can guess what that person thinks like and thus it gives a result about his/her
personal details.It performs a bit slowly. It is multi-lingual bot having competence over many other languages other than English. Although
it cannot speak Bengali, however it can detect Bengali language when a person gives it massage in Bengali. But this bot cannot do computational
operation. When numerical values are put, it gives absurd result. So in a word this bot is very useful in terms of
mutual chatting. This bot is available in the form of web application, software, mobile app etc.
Mitsuku:
Mitsuku is an award winning chatterbot representing an 18 year old girl's avatar. Her intelligence power includes the ability to reason with
specific objects. For example, if someone says "Can you eat a house?", Mitsuku looks up the properties for "house". Finds the value of "made_from" is set
to "brick" and replies no, as a house is not edible.
She can play games and do magic tricks at the user's request.It performs faster than cleverbot giving reply very very instantly. It is not able to speak
multiple languages. But its unique feature is the ability to perform computational operation amazingly. Its intelligence is more than chatterbot. This
bot can also be run through social media like facebook.
Conclusion:
In the upcomg generation it is expected that the use of bots for communication with common people will be increasing gradually day by day. As a result,
tasks will be reduced and can be done more efficiently 
and smoothly by means of bots. Cleverbot and Mitsuku both are
very good and standard examples of internet bots indeed.
