WHAT IS A CHATBOT???
A CHATBOT is an artificial intelligence (AI) software that can
simulate a conversation (or a chat) with a user in natural
language through messaging applications, websites, mobile
apps or through the telephone.
The last decade saw bots as an integral part of tech
companies. For example, IBM has Watson, Apple has Siri,
Google has Google Now, Samsung has SVoice, Amazon has
Alexa, Microsoft has Cortana and Facebook has Portal
(backed by Alexa).
WHAT IS A CHATBOT?

AI Based: These chatbots thrive on dynamic learning
and constantly update themselves using various
interactions. They are intelligent, of superior design,
offer better user-experience.
Rule Based: These are programs with fixed information
and hence offer limited help. They are used for
with limited customer access or to resolve back-end
However, fixed chatbots are not-so-popular due to their
inability to understand perplexed human behavior. Also,
may not be able to handle all the queries and hence
across as a challenge while interacting.

SMART AS THE WORDS YOU FEED
THEM.

There are two different tasks at the core of a chatbot: 1) User RequestAnalysis 2)
Returning the Response
WORKING OF A CHATBOT

This is the first task that a chatbot performs. It analyzes
the user’s request to identify the user intent and
to extract relevant entities.
The ability to identify the user’s intent and extract data
and relevant entities contained in the user’s request is
the first condition and the most relevant step at the
core of a chatbot. If you are not able to correctly
understand the user’s request, you won’t be able to
provide the correct answer.
USER REQUEST ANALYSIS

Once the user’s intent has been identified, the chatbot must
provide the most appropriate response for the user’s request.
The answer may be:
•A generic and predefined text
•A text retrieved from a knowledge base that contains
different answers
•The result of an action that the chatbot performed by
interacting with one or more backend application
•A disambiguating question that helps the chatbot to
correctly understand the user’s request
RETURNINGTHE RESPONSE

Messaging is the new
browser, and bots
are the new
websites.

EXAMPLES OF CHATBOTS

MESSAGING APPS ARE WHERE
PEOPLE SPEND THEIR TIME
ONLINE.
CHATBOTS ARE A WAY TO REACH
THEM.

If you suffer from insomnia, you’ll know that the feeling of
almost suffocating loneliness – the idea that everyone else in
the world is resting peacefully while your own mind betrays
you with worries and doubts – is among the worst parts of
not being able to sleep.
Enter Casper’s amazingly named Insomnobot 3000, a
conversational agent that aims to give insomniacs someone
to talk to while the rest of the world rests easy.
CASPER

This chatbot aims to make medical diagnoses faster, easier,
and more transparent for both patients and physicians –
think of it like an intelligent version ofWebMD that you can
talk to. MedWhat is powered by a sophisticated machine
learning system that offers increasingly accurate responses
to user questions based on behaviors that it “learns” by
interacting with human beings.
In addition to the ever-growing range of medical questions
fielded by MedWhat, the bot also draws upon vast volumes
of medical research and peer-reviewed scientific papers to
expand upon its already considerable wealth of medical
expertise.

Chatbots can be operational 365 days a year and 24 hours a
day, allowing them to serve your customers even while
you’re sleeping or doing other tasks.
ADVANTAGES OF A
CHATBOT
ROUNDTHE CLOCK SERVICE

Contemporary consumers desire immediate results and lean
on businesses that deliver on promptness.
One study on chatbot user experience found that 40 percent
of consumers don’t care whether a human or a chatbot
responds to their questions as long as they get quick help.
ADVANTAGES OF A
CHATBOT
INSTANTEOUS RESPONSE

Chatbots can be easily accessed by users who are
increasingly moving away from traditional phone inquiries
and want everything accessible from their mobile phone.
ADVANTAGES OF A
CHATBOT
EASY ACCESS

It’s potentially a huge
business opportunity for
anyone willing to jump
headfirst and build
something people want.“

Due to fixed programs, chatbots can be stuck if an unsaved
query is presented in front of them.This can lead to customer
dissatisfaction and result in loss.
It is also the multiple messaging that can be taxing for users
and deteriorate the overall experience on the website.
DISADVANTAGES OF A
CHATBOT
INABILITYTO UNDERSTAND

Chatbots are not able to memorize the past conversation
which forces the user to type the same thing again & again.
This can be cumbersome for the customer and annoy them
because of the effort required.
DISADVANTAGES OF A
CHATBOT
POOR MEMORY

Chatbots are known for being infamous because of their
inability to make decisions.
A similar situation has landed big companies like Microsoft
etc. in trouble when their chatbot went on making a racist
rant.
Therefore, it is critical to ensure proper programing of your
chatbot to prevent any such incident which can hamper your
brand.

I see speech approaching a point
where it could become so reliable
that you can just use it and not
even think about it.

From my perspective, chatbots or smart assistants with
artificial intelligence are dramatically changing businesses.
Chatbots can reach out to a large audience on messaging
apps and be more effective than humans.They may develop
into a capable information-gathering tool in the near future.
