4. What is a bot?
A bot is a program that
automates a task. Users
interact with it through
messaging channels. The
bots understand the
request and perform an
action.

11. A bot is made of intents
An intent is a set of
expressions that mean
the same thing but are
constructed in different
ways. Each one of your
intents represents an
action your bot is able to
understand.
12. Every intent is trained with expressions
An expression is a
sentence your bot can
understand: basically your
users’ inputs. Expressions
are organized in intents
and constitute the entire
knowledge of your bot.

INTENT
I want to watch a movie Any good western tonight? I want to start a new show!
greetings weather
The more expressions you have, the more precisely your bot will be able to understand its
users. The aim is to detect in which intent box an expression the bot has never seen is.
14. Entities are extracted from each expression
An entity is a keyword
extracted from an
expression. We detect
automatically 31 different
entities such as
datetimes, names,
locations, etc.
15. Entities with a black star next to them are called Gold entities.
They are automatically detected and extracted. But you are not
limited to these Gold entities: you can also tag your own
custom entities to detect keywords depending on your bot's
context, such as movie genres if you are building a movie bot.
17. A bot conversation is made of Skills. A skill defines a specific
block of conversation that has a clear purpose. A skill can be
as simple as the ability to greet someone, but it can also be
more complex, for example giving movie suggestions based
on information provided by the user.

Fallback
Skills type
There are 3 different types of skills
21. Triggers
Conditions determining if the skill should or shouldn't be activated
Requirements
Determining the information the bot needs to retrieve from the user, and how to
retrieve it
Actions
performed by the bot when all requirements are complete (for example, send a
message)
Skill logic
It is composed of three distinct parts
22. Skills have conditions
Conditions define tests
that will either be true or
false. You will find
conditions in different
parts of your skill:
triggers, requirements and
in each message group in
actions.
23. Conditions have operands
Inside your data
conditions, you will find a
list of operands.
@ means intent
# means entity
_ means NLP attribute
24. Entities SkillsIntents
To summarise a bot is made of intents
that are made of expressions that contain
entities. Intents and entities are used by
Skills to manage conversation
