3 Telegram
4 Text Messages / iMessage
5 ...
in any major chat products...

5. Why use chatbots?

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

Mike Roberts, Head of Messaging @ Kik, said this:

7. Development cost

10. • Simple to develop
• Asynchronous notifications
• Integrates with team
Chatbot advantages

11. How does it work?
User makes a request Request analyzed
by artificial intelligence
User info taken into account
(history, preferences…)
Real time response
Conversational strategy
Interactions personalization
…

12. TWO TYPES OF CHATBOTS
1. Based on rules
2. Based on Artificial
intelligence

Advance Intent Recognition Challenge
“The city councilmen refused the demonstrators a permit because they feared violence”
“What does the word “they” refer to here — the councilmen or the demonstrators? What if instead of “feared”
we wrote “advocated”?”(1)
“Oren Etzioni: When AI can’t determine what “it” refers to in a sentence, it’s hard to believe that it will take over
the world”(1)

Intent Recognition Training Model Guideline
“intents should be different enough to help the ML disambiguate better”
“Good Pizza vs Bad Pizza are not two different intents, the intent here would be Pizza Quality, Good and Bad would
be entity Rating”
“single keywords are not useful”
“unique sentences are super helpful, semantically and synonym rich”
“do {word} sentence construction in different intent models will falsely give high prediction score for all intents”

Entity Recognition (NER)
“the ability to automatically recognize entity meanings from ambiguous language”
“despite all improvements in ML, the problem of accurate entity recognition is far from been solved”
“main effort currently is directed to find approaches to reduce the annotation labor – semi-supervised NER”

“evaluate subjective patterns and expressions of sentiment within textual content”

sentence, given a statistical model of the syntactic structure of a language”
