Header keywords¶

concept¶

Syntax

concept:(name) [word1 word2 "word3 word4"]

Where:

word1 and word2 are isolated words,
“word3 word4” is a phrase, i.e. a group of several words,
name is the name of the static concept gathering all the items in an ordered list.

Note: a static concept can contain choices, optional words and phrases, concepts (static and dynamic), functions (^rand, ^first), variables and conditions.

Usage

Defines a static list of items (words and/or phrases).

Warning

Phrase means a group of word, not a sentence, be aware that any punctuation character will be automatically removed.

Static concepts are global, in other words, they are usable in different Topics.

To use a concept in a rule, see: Concept call: ~.

Example

topic: ~introduction ()
language: English

concept:(greetings) ^rand[hi hello "hey there"]

concept:(wine) [red white] wine
concept:(alcohol) [beer ~wine]

u:(~greetings) ~greetings
u:(do you have _~alcohol) yes, I have $1
u:(I want to drink something) do you want ~alcohol?

Execution

> hey there
hello
> do you have white wine?
yes, I have white wine
> I want to drink something
do you want beer?
> I want to drink something
do you want red wine?

dynamic¶

Syntax

dynamic:name

Note: a dynamic concept can only contain a list of words or phrases between a single choice [ ].

Usage

Declares a dynamic list of items (words and/or phrases). This list is local to a Topic.

Conditions

Dynamic concepts must be modified at runtime, using:

ALDialogProxy::setConcept

To use a concept in a rule, see: Concept call: ~. Concepts are global, setConcept will affect the concept in all topics.

Warning

Be aware that adding too many items in a Dynamic concept will affect loading duration; For instance, loading a Dynamic concept containing thousands of sentences may take several minutes.

Example

topic: ~dynamic()
language: English

dynamic:mp3
u:({please} ["i want" play] _~mp3) let's play $1

# call it when speech recognition is running
proxy = ALProxy("ALDialog")
proxy.setConcept("mp3","English", ["mika", "queen", "village people", "boy george"])

^clearConcept¶

u:(input) ^clearConcept(~dynamicConceptName)

Usage

Removes all sentences from dynamic concept.

Example

dynamic:fridge
u:(put drinks in the fridge) ok ^addToConcept(~fridge, coke) ^addToConcept(~fridge, beer)
u:(what's in the fridge) The fridge contains ^size(~fridge) drinks
u:(empty the fridge) ok, I empty the fridge ^clearConcept(~fridge)

Execution

> put drinks in the fridge
ok
> what's in the fridge
The fridge contains 2 drinks
> empty the fridge
ok, I empty the fridge
> what's in the fridge
The fridge contains 0 drinks

dynamic:fridge
u:(fill the fridge) ok ^addToConcept(~fridge, coke) ^addToConcept(~fridge, beer)
u:(what's in the fridge) the fridge contains ^enumerate(~fridge)
u:(remove the _~drink from the fridge) ok ^removeFromConcept(~fridge, $1)

Execution

> fill in the fridge
ok
> what's in the fridge
The fridge contains coke beer
> remove the coke from the fridge
ok
> what's in the fridge
The fridge contains beer

Related functions

include: file.top

Note: include must be specified just after the name and the language of a topic, and before the first concept or rule.

Usage

Includes a file in the topic.

Conditions

The included file must be in the same folder than the topic that calls the include.

Effect

An included topic has the same behavior than topic:

The included file is loaded as soon as the calling topic is loaded.
The included file is activated as soon as the calling topic is activated

Example

topic: ~ok()
language: English
# suppose my_lexicon_enu contains concept ~confirmation and ~negation
include:my_lexicon_enu.top
u:(hello) are you ok ?
   u1:(~confirmation) yupi
   u1:(~negation) Doh !

Specific case: include Basic Channel & Lexicon

language: English

include: lexicon_enu.top

topic: ~my_own_topic()
language: English

include: dialog_adjust_volume/dlg_adjust_volume/dlg_adjust_volume_enu.top

For further details, see:

description¶

Syntax

description: cook

Description must be specified just after the include.

Usage

Current focus description is in variable $Dialog/FocusDescription. If focus doesn’t have description, then variable is empty.

overload¶

Syntax

overload: topicName

Warning

The overload keyword must be placed before the include one (if any).

Allows you to redefine another topic. The overloaded topic will never be activated.

Example

topic: ~mysetup()
language: English

overload: mysetup
u:(raise your volume) I don't want to make it

pronunciation¶

Syntax

pronunciation:(word) wordPronunciation

Changes the default speech recognition way to pronounce a word. For example “I” should be pronounced “capitalize i”.

Note: Following words pronunciation are automatically managed by dialog engine: “I” in English and “à” in French.

topic: ~play()
language: English

pronunciation:(I) [i]
u:(I want to play) let's play

language¶

Syntax

language: English

language: enu # DEPRECATED since 2.7

Usage

Defines the language of the topic.

A topic can have the same name in different languages. For example in English “cars” topic and cars topic in French. In a language, a topic must have a unique name.

For further details see: nao Dialog - List of supported Languages or pepp Dialog - List of supported Languages.

topic¶

Syntax

topic: ~name ()

Usage

Defines the name to the topic. A topic must have one name and can have only one.

The name of a topic must be unique in a given language.

Related functions

Topic properties.

def¶

Syntax

def:name($parameter1, $parameter2, ..) robot output

Note:

Every parameter is local to the function in which it has been defined. Outside of this function every occurrence of $parameter1, $parameter2, .. will be replaced by the value stored in ALMemory.

Usage

Defines a function which can be used in other qiChat rules as any function.

Related functions

^defined_function

Rules¶

User rule¶

Syntax

u:(Input) Answer
u:(Input)
  Answer

Where:

Input is the Human input,
Answer is the Robot output.

Indentation and blank lines are ignored.

Usage

Makes the robot say or do the Answer when he hears the Input.

Effect

If the Human input matches, then the topic that contains the rule takes the focus.

For further details, see: Focus.

Conditions

The topic containing the user rules must be activated to answer.

Example

topic: ~introduction ()
language: English

u:(hello) hello human
u:(how are you) I feel tired, my batteries are low

Execution

> hello
hello human
> how are you
I feel tired, my batteries are low

Related functions

Rule functions and properties.

User subrule¶

Syntax

u:(input1) answer
   u1:(input2) answer
   u1:(input3) answer
     u2:(input4) answer
        u3:(input5) answer
     u2:(input6) answer

proposal: sentence
   u1:(input7) answer
   u1:(input8) answer

Where u1:, u2: and u3: are user subrules.

The indentation underlines the relationship between a rule and its subrules.

Usage

Allows creating several conversational contexts, making some rules activated if and only if a main User rule or Proposal has previously matched.

Activation / deactivation

At first, the User rules and Proposal are activated while subrules are deactivated.

If a User rule matches and if it has a scope, its subrules (u1:) are activated; the other User rule remain activated.
If one of the u1: subrule matches, then its own subrules (u2:) are activated, and the first-level rules (u1:) are deactivated.
At anytime, if another User rule matches, then the previous subrules are deactivated.

Scope: The subrules of a rule are called the scope of the rule.

Example

topic: ~introduction ()
language: English

u:(talk about animals) do you have a cat or a dog?
   u1:(dog) is it a big dog?
     u2:(yes) make sure he has enough space to run
     u2:(no) it is so cute
   u1:(cat) do you live in the countryside?
     u2:(yes) does your cat goes outside?
        u3:(yes) does he hunt mouses?
     u2:(no) i hope your flat is big enough
   u1:(none) neither do I

u:(talk about sport) what a good idea

proposal: Do you want to talk about sport?
   u1:(yes) Cool
   u1:(no) OK

Execution

> talk about animals
do you have a cat or a dog?
> I have a cat
do you live in the countryside?
> no
I hope your flat is big enough
> Now I want to talk about sport
what a good idea

Proposal¶

Syntax

proposal: sentence

Where:

sentence is a Robot output.

Usage

While rules are triggered by a Human input, to be said, a Proposal needs to be triggered with one of the topic progression functions:

^nextProposal,
^previousProposal,
^sameProposal,
^goto,
^gotoRandom,
^gotoReactivate, or
^topicTag.

Activation/deactivation

When a proposal is said, then it cannot be said again except if the proposal is re-activated by ^gotoReactivate.

Conditions

The Topic containing the user rules must be active.

Example

topic: ~introduction ()
language: English

proposal: take a cup and fill it with milk
proposal: add 3 strawberries
proposal: add some vanilla ice cream
proposal: close the cup with the lid and shake it
proposal: you did it! you can enjoy your milkshake

u:(I want a milkshake)
    ok, let's do it.
    follow my instruction and say next when you are ready for the next step.

u:(next) ^nextProposal

Execution

> I want a milkshake
ok, let's do it.
follow my instruction and say next when you are ready for the next step.
>next
take a cup and fill it with milk
>next
add 3 strawberries
>next
add some vanilla ice cream
>next
close the cup with the lid and shake it

Learning rule¶

Syntax

l:(input) output

Usage

Additional rule that can match in parallel of other rules. The rule as no effect on speech recognition.

Example

topic: ~love()
language: English

u:(i love robots) i love robots to
l:(i love _*) $love=$1 # this rule is matched at the same time than previous rule

u:(what do i love) you love $love

Delimiters¶

Choice: [ ]¶

Syntax

u:([word1 word2 wordn]) answer
u:(input) [word1 word2 wordn]
u:([word1 word2 wordn]) [word1 word2 wordn] human

Where:

word1 to wordn are words that could substitute with each other.

Warning

Never write [{xxx}] the dialog engine will accept it but this rule will always match, whatever you write inside.

Usage

In a Human input: creates one rule accepting variations.
In a Robot output: if the rule is triggered several times, the words will be used sequentially in order to create varying responses.

Example

topic: ~introduction ()
language: English

u:([hi hello]) [hello hi] human

The Human input can be ‘hello’ or ‘hi’. The Robot output can be ‘hello human’ or ‘hi human’. By default answers are in a sequential order.

Execution

> hello
hello human
> hello
hi human
> hi
hello human

Related functions

^first.
^rand.
^repeat.

Phrase delimiter: ” “¶

Syntax

u:([word1 "phrase 1"]) ["phrase 2" "phrase 3"]

Where:

word1 is a word that could substitute with phrase 1.
phrase 2 and phrase 3 are phrases used sequentially in order to create varying responses.

Usage

Allows you to place a phrase instead of a single word in a choice [] or an optional part {}.

Warning

Single quotes ‘ ‘ do not concatenate words together. If you need to concatenate words into a phrase, you must use double quotes " ".

Example:

u:(hello [“my mate” “my friend”]) is interpreted correctly, but

u:(hello [‘my mate’ ‘my friend’]) is interpreted as u:(hello [my mate friend])

Example

topic: ~introduction ()
language: English

u:(["hello how are you" "hello are you OK"]) ["I am fine" "I am OK"]

Execution

> hello are you OK
I am fine
> hello how are you
I am OK

Optional part: { }¶

Syntax

u:(beginning of the sentence {optionalWord} end of the sentence) answer
u:(input) beginning of the sentence {optionalWord} end of the sentence
u:(beginning of the sentence {"optional phrase"} end of the sentence) answer
u:(input) beginning of the sentence {"optional phrase"} end of the sentence

Where:

optionalWord is a word that could appear or not in the Human input or the Robot output.
optional phrase is a phrase that could appear or not in the Human input or the Robot output.

Usage

Optional word or phrase, at the beginning, the middle or the end of a sentence.

Conditions

Inside a Choice: [ ], optional word for Human input can only be used inside a phrase:

Not correct: u:([chocolate milk {bread}])
Correct: u:([chocolate milk “{white} bread”])

Example 1

topic: ~introduction()
language: English

u:(hello {buddy} how are you) hello I am fine

Execution of Example 1

>hello how are you
hello I am fine
>hello buddy how are you
hello I am fine

Example 2

topic: ~introduction()
language: English

u:(hey) hello {human buddy}

Execution of Example 2

>hey
hello human
>hey
hello buddy
>hey
hello

In this example, each element inside of the Optional part: { } is picked with a probability of 1/3 (corresponds to a choice: [human buddy ^empty]).

Related rules

^empty.

Special characters¶

Comments: #¶

Syntax

# comment

Comment is defined by character #. All the characters following # in the same line will be ignored.

Wildcard: *¶

Syntax

u:(sentence * sentence) answer

Usage

Matches any word or phrase.

Use wildcards sparingly

Too many wildcards can degrade performance of the automatic speech recognition.

Example

topic: ~introduction ()
language: English

u:(my name is *) nice to meet you
u:(I like to * a lot) it sounds cool

Execution

> my name is David
nice to meet you
> I like to dance a lot
it sounds cool
> I like to play tennis a lot
it sounds cool

Forbidden word: !¶

Syntax

u:(sentence !forbiddenWord) answer

Usage

Allows you to define a forbidden word in a Human input.

Example

topic: ~introduction ()
language: English

u:(tell me a story) OK, a new one?
u:(!don't tell me a new one) great, I'll tell you a new story!
u:(don't tell me a new one) Ok, so I'll tell you the story of Peter Pan.

Execution

> tell me a story
OK, a new one?
> tell me a new one
great, I'll tell you a new story!

Tag: %¶

Syntax

proposal: %tag sentence
u:(input) %tag answer

Usage

Allows you to identify one or several proposal(s) or rule(s) by a tag. Tags can be activated or deactivated. If a tag is deactivated, then the sentence is false and won’t be said.

Example

topic: ~introduction ()
language: English

proposal: %weather what is the weather like today?
u:(tell me a story) %story ok, I'll tell you the story of the three bears

^topicTag.

Input storing: _¶

Syntax

u:(sentence _[word1 word2]) answer $1

u:(sentence _~concept) answer $1

u:(sentence _*) answer $1

Where:

_[word1 word2] is the choice of words the robot will be able to catch and reuse.
$1 is the first caught word.

If there are several _, $2 is the second caught word, $3 is the third, etc. There is no limitation in variable number.
_~conceptName allows catching any word included in a concept. For further details, see: Concept call: ~.
_* allows catching any word said using the speech recognition.

Warning

_* is not available for all robots and all languages, it requires a specific remote speech recognition license.

For further details, see: Remote ASR Engine - List of supported Languages.

Note: giving a choice of words to recognize eases the speech recognition.

Usage

Allows catching one or several words in the Human input and reuse it within the Robot output directly following.

Tips: if you need to reuse the value elsewhere in the dialog, store it in a variable.

u:(my name is _*) nice to meet you $1 $name=$1

Example

topic: ~introduction ()
language: English

u:(my name is _*) nice to meet you $1
u:(I like _[chocolate cheese]) do you want to eat $1 now?

Execution

> my name is David
nice to meet you David
> I like cheese
do you want to eat cheese now?
> I like chocolate
do you want to eat chocolate now?

Related functions

Wildcard: *.
Concept call: ~.
Variable: $.

Variable: $¶

Syntax

# Affect a variable
u:(input) answer $variableName=value

# Use a variable in a robot answer
u:(input) answer $variableName

Where:

variableName is the name of the variable.

Note: For each variable $variableName, an event e:variableName is also available. Variable are stored in ALMemory. e:variableName subscribes to ALMemory event.

Note: $user/variable=value automatically stores in a database the value for the current user. The current user is identified by ALDialogProxy::openSession method called by ALAutonomousLife.

Warning: Do not affect and read the variable in the same sentence. A variable is affected only when the sentence has been fully said.

Usage

Variables cannot be used the same way in Human input or Robot output. Indeed, in a Human input, it is only possible to trigger a rule by testing a condition on a variable if the associated event is declared in the input, or if a normal input is also present.

Variables are global, i.e. they can be used in several behaviors.

They don’t have a type and don’t need to be declared, they can be directly affected and used in rules.

They can be:

set
used in a Robot output
used in conditions (see: Conditions: == > <> <).

Example

topic: ~introduction ()
language: English

   u:(I want some _[chocolate cheese]) OK $askedFood=$1
   u:(what did I ask) ^first["you asked $askedFood" "I don't know"]

Execution

> what did I ask
I don't know
> I want some chocolate
OK
> what did I ask
you asked chocolate

Related functions

^first,
^clear.

Conditions: == > <> <¶

Syntax

# condition on variable
u:($variableName==value) answer

# answer if variable>value
u:(input) answer $variableName>value

# answer if variable<value
u:(input) answer $variableName<value

# answer if variable different from value
u:(input) answer $variableName<>value

# condition on variable in human input, using an event
u:(e:FrontTactilTouched $FrontTactilTouched==1) answer

# condition on variable in human input
u:("input $variableName==value") answer

# condition on variable in answer
u:(input) ["answer $variableName==value" "another answer"]

Usage

Placed in a Human input or in a Robot output, a condition:

triggers the rule if true,
blocks the rule if false.

A condition based on an empty variable will be ignored.

The condition ordering does not matter.

If condition is false anywhere in quote, then the sentence in quote will not be said.

Example

topic: ~introduction ()
language: English

   u:(I want some _[chocolate cheese]) OK, you want some $1 $askedFood=$1
   u:(what did I ask) ^first ["you asked $askedFood" "I don't know"]
   u:(can I have more)
   ^first["$askedFood==chocolate sorry, too much chocolate could hurt you"
   "yes, please take more $askedFood"]

Robot events: e:eventName¶

Syntax

u:(e:event) answer
# will answer whenever the event "event" is raised

u:([e:event sentence]) answer
# will answer whenever the event "event" is raised or the sentence is said.

u:("e:event sentence") answer
# will answer whenever the event "event" is raised and then the sentence is said
# (the event must be raised before saying the sentence)

u:(e:MyService.MySignal) answer
# will answer whenever the signal "MyService.MySignal" is raised

Note: For each event, e:eventName a variable $eventName is also available.

Note: In Choregraphe qiChat events and input/output can have the same name. If an event have the same name than box input/output, the variable is only linked to the box and is not anymore usable with ALMemory.

Note: Only one event can be matched at a time. If several events are raised at the same time, other events with the same name are rejected until dialog engine answered. Other events with different names have two seconds to be matched by dialog engine or they will be rejected.

Note: Compatible events can be both ALMemory events or qiChat events but not signals.

Usage

Catches an event.

Allows to catch:

any NAOqi Events providing information related to the robot: movement, battery information, face information,
any ALDialog event list providing information about the Dialog engine,
the events raised each time a value is assigned to a variable,
any signal available in NAOqi services.

Note

Robot output cannot occur at high frequency, both data and event are merged.

Conditions

The subscribe will only occur when the topic is activated. The unsubscribe will occur when the topic is deactivated.

Example

topic: ~introduction ()
language: English

u:(be my puppet) ok, touch my leg or ask me
u:([e:LeftBumperPressed "move this leg"]) ok I move the left leg
u:(e:LeftBumperPressed "light this leg") ok I turn leds on left leg

Execution

>be my puppet
ok, touch my leg or ask me
>(user touch the left bumper)
ok I move the left leg
>(user touch the left bumper) light this leg
ok I turn leds on left leg

Concept call: ~¶

Syntax

u:(~conceptName) answer
u:(input) answer ~conceptName

Usage

A Concept can be used both in Human input or Robot output to replace a list of item previously declared.

In Human input, the rule will match if anyone of the items of the list is recognized.
In Robot output, one item of the list will be said. Each call of the rule will call sequentially another item of the list.

Conditions

the Concept must be previously defined.

To define a concept, see: concept and dynamic.

Example

topic: ~introduction ()
language: English

   concept:(want) [want need desire like]
   concept:(alcohol) [beer vodka "red wine"]
   concept:(child-drink) ["orange juice" milk]
   concept:(drink) [~alcohol ~child-drink]

   u: (what do you do) I can help people with drinks

   u:(I ~want to drink) what you ~want to drink?
        u1:(* _~drink) do you want me to search $1 for you?

Execution

> what do you do
I can help people with drinks
> I need to drink
what do you want to drink?
> I want red wine
do you want me to search red wine for you?

Forbidden characters¶

Forbidden characters in Human input¶

Type only the words to be recognized.
Do not use any punctuation mark.
Do not use any special characters, for example:
- instead of ‘$’, type: ‘dollar’
- instead of ‘.’, type: ‘dot’
Apostrophe ( ‘ ) is allowed but not the typographic apostrophe ( ’ ).

Japanese only:

speech recognition does not support Fullwidth numbers [０１２３４５６７８９]. Use Halfwidth numbers [0 1 2 3 4 5 6 7 8 9] instead.

Example

topic: ~introduction ()
language: English

u:(have you a dollar for me) No, sorry, I have no pocket!
u:(I'm rich) good for you. Are you happy?

Forbidden characters in Robot output¶

like all Special characters, $ is a reserved word, type dollar instead.
warning: the character ‘.’ is a punctuation character, therefore, the robot will not read it:
- Instead of ‘toto.png’, type: ‘toto dot png’
Apostrophe ( ‘ ) is allowed but not the typographic apostrophe ( ’ ).

Example

topic: ~introduction ()
language: English

u:(have you a dollar for me) No, sorry, I have no pocket!
u:(I'm rich) good for you. Are you happy?

Rule functions and properties¶

^activate ^deactivate¶

Syntax

u:(input) answer ^deactivate(tag)
u:(input) answer ^activate(tag)

Usage

^deactivate function deactivates a tag, ^activate function reactivates a tag.

If a Robot output contains a deactivated tag, this Robot output cannot be triggered.

Example

topic: ~introduction()
language: English

proposal: %greeting1 hello
proposal: nice to meet you
u:(hello) hello ^deactivate(greeting1)
u:(say something) ^nextProposal

Execution

> Hello
Hello
> say something
nice to meet you

^break¶

Syntax

u:(Input) Answer1 ^break answer2

Effect

Forces dialog engine to re-evaluate the rest of the sentence. Useful when data you want to say may change between the beginning and the end of a sentence. Dialog engine automatically re-evaluates data after:

^gotoReactivate

Example

topic: ~break()
language: English

u:(what is your position) my position after this sentence is ^break ^call(ALRobotPosture.getPosture())
c1:(_*) $1

^clear¶

Syntax

u:(input) ^clear(variableName)

Usage

Clears a variable. A cleared variables cannot be said. A sentence with cleared variable cannot be said. A condition with cleared variable is always false.

Example

topic: ~introduction ()
language: English

u:(my name is _*) nice to meet you $name=$1
u:(what is my name) ^first["your name is $name" "I don't know"]
   u1:(no) OK ^clear(name)

Execution

> my name is David
nice to meet you
> what is my name
your name is David
> no
OK
> what is my name
I don't know

Related functions

^first.

^concatenate¶

Syntax

u:(input) ^concatenate(word1, word2)
u:(input) ^concatenate(word1, word2, ...)

Usage

Concatenates a word list to create only one word.

Example

topic: ~con()
language: English

u:(happy) ^concatenate(i', m) happy

^empty¶

Syntax

u:(input) ^empty

Usage

Used when the robot should not answer.

Tip: can be used inside a Choice: [ ], e.g. the robot does not answer immediately to a Human input but only the second time.

Warning

Do not use empty string “” for this purpose: empty strings are skipped.

Example 1

topic: ~example1()
language: English

u:(hello) [^empty "Hi human"]

#Warning :
#u:(hello) ["" "Hi human"] will not work the same way, as "" are skipped.

Execution of Example 1

>hello
(no robot output)
>hello
Hi human

Example 2

topic: ~example2()
language: English

u:(hello) ^goto(tag)
u:(test) ^empty
u:(^empty) %tag "Hi human"

Execution of Example 2

Hi human
>test
(no robot output)

^enumerate¶

Syntax

u:(input) ^enumerate(~conceptName)
u:(input) ^enumerate(~conceptName, 2)

Usage

Enumerates all the elements of a static or dynamic concept.

A second parameter can be used to limit the number of enumerated elements. Calling several time the function will move forward in the concept.

Example

topic: ~introduction ()
language: English

concept:(alcohols) [beer "[red white] wine"]
u:(what are your drinks) I have ^enumerate(~alcohols)
u:(enumerate your drinks) I have ^enumerate(~alcohols, 2)

Execution

^exist ^notExist¶

Syntax

topic: ~exist()
language: English
u:(hello) ["^exist(42) the variable exist" "^notExist(42) the variable doesn't exist $42=1"]

Usage

A sentence that contains ^exist won’t be said if the variable parameter does not exist or is an empty string.

^first¶

Syntax

u:(input) ^first [answer1 answer2]

# Inside a choice, requires quotes
u:(input)  [answer1 "^first [answer2 answer3]"]

Usage

When added before a Choice: [ ] in the Robot output part, instead of using each answer in turn, the interpreter always use the first valid Robot output.

A valid Robot output is an answer:

without any condition nor non-affected variable,
including affected variable(s),
including a condition tested as true.

Using a non-affected variable in a robot output will make the rule invalid, i.e. the rule will not be said at all.

To avoid this situation, use the function ^first before a choice [ ].

This function tries to say the first valid output. If the first element of the choice is invalid because it contains a non-affected variable, it will try the second element, and so on. But if no output is valid, the rule will still be invalid. If you want to be sure robot always answer, see: ^firstOptional.

Example

topic: ~introduction ()
language: English

u:(my name is David) nice to meet you David $name=David
u:(my name is Paul) nice to meet you Paul $name=Paul
u:(what is my name) ^first["your name is $name" "I don't know"]

Execution

> what is my name
I don't know
> my name is David
nice to meet you David
> what is my name
your name is David

For further details, see : Conditions: == > <> <.

^firstOptional¶

Syntax

u:(input) ^firstOptional [answer1 answer2]

# Inside a choice, requires quotes
u:(input)  [answer1 "^firstOptional [answer2 answer3]"]

Usage

This function tries to say the first valid output. If the first element of the choice is invalid because it contains a non-affected variable or a condition that evaluates to false, it will try the second element, and so on. If none of the elements is valid, the ^firstOptional will be evaluated as nothing.

Example

topic: ~introduction ()

u:(my name is David) nice to meet you David $name=David
u:(my name is Paul) nice to meet you Paul $name=Paul
u:(my name is a secret) I won't tell anyone ^clear(name)
u:(hello) good morning ^firstOptional["$name"]

Execution

> my name is David
nice to meet you David
> hello
good morning David
> my name is a secret
I won't tell anyone
> hello
good morning

For further details, see : Conditions: == > <> <.

^frequency¶

Syntax

^frequency(uniqueTagName,StartAfter,RepeatEvery,DefaultValue)

Where:

uniqueTagName is a unique string.
startAfter is a time interval in minutes, defining the initial value of the timing.
repeatEvery is a time interval in minutes, defining the value of the timing after the first activation.
DefaultValue is a boolean: if 0, the rule will not be valid until activation, if 1 the rule is valid.

Usage

Defines how often a rule is activated or reactivated.

The timing value is stored in a database and will be persistent after the Dialog Engine restart. If default value is 0, then the uniqueTagName must be activated with ^activate.

Example

topic: ~frequencytopic ()
language: English

## answers once every minutes
u:(What time is it) ^frequency(first,1,1,1) ^currentTime

## will answers only if the tag second is activated
u:(are you silly) (second,1,1,0) don't bully me ^frequency

## answers after 2 minutes then every minutes
u:(are you still there) ^frequency(third,2,1,1) yes I am here

## activates tag second
u:(activate answer) ^activate(second)

^goto¶

Syntax

u:(input1) %tag Answer
u:(input2) ^goto(tag)

u:(help for music ^exact) I can help you to choose music by voice.

^rand¶

Syntax

u:(input) ^rand[answer1 answer2]

Usage

Can be added before a choice [] in the Robot output.

A valid Robot output is:

an answer including a condition tested as true or
an answer including no condition at all.

Rand function in a choice needs to be inside quote.

For further details, see: Conditions: == > <> <.

Example

u:(hello) ^rand[hello hi "what's up" "hey there"]

^repeat¶

Syntax

u:(^repeat[word1 word2 word3]) answer

Note: Repeat allows you to use words or sentences from one to ten times.

Warning

This function is tricky. Avoid to start your first interaction with repeat. Avoid to use Wildcard * in repeat.

Usage

Allows a free combination of listed words.

The Human input is recognized if one or several word(s) among the list are said, regardless of the order.

^sameProposal¶

Syntax

u:(input) answer ^sameProposal

Usage

The function ^sameProposal repeats the last proposal said in the same topic.

Best practices

When using ^sameProposal, always make the robot say something like ‘Ok I’ll repeat’, ‘No problem,’ so that the user knows what to expect. It also makes the repetition clearer.

Example

topic: ~introduction ()
language: English

u:(hi) hello ^nextProposal

proposal: how are you?
  u1:(I'm fine) cool!
  u1:(I'm tired) oh ^nextProposal

proposal: do you want some coffee?
   u1:(yes) I'm bringing you a cup of coffee.
   u1:(no) okay, maybe you should just take a nap.
   u1:(can you repeat please) Ok I'll repeat. ^sameProposal

Execution

> hi
hello how are you?
> I'm tired
do you want some coffee?
> can you repeat please
Ok I'll repeat. Do you want some coffee?
> yes
I'm bringing you a cup of coffee.

Transformation rules¶

Skin: s:¶

Syntax

s:(Answer) Modifications
s:(Answer)
Modifications

Where:

Answer is the Robot output we want to match to apply this skin
Modifications the modifications ^addword or/and ^replace we want to apply to the answer

Usage

When a Robot output matches a skin the robot says the Answer after Modifications are applied.

^addword¶

Syntax

s:(Answer) ^addword(Expression, Position, Frequency)

Where:

Answer is the Robot output to be matched
Expression can be any string (word(s), concept...)
Position is the position where you want to add the expression in the sentence.

This parameter can be:
- an integer: for instance “2” if you want to put the Expression in the second position
- “end” if you want the Expression to be added at the end of the sentence
- “start” if you want the Expression to be added at the beginning of the sentence
Frequency represents the probability of the skin to be applied (1:always apply, 0:never apply)

Usage

Add an Expression in each Robot output matching the skin.

Conditions

The rule must be active.

Example

topic: ~introduction ()
language: English

u:(hello) hello human
u:(how are you) I am fine

s:(hello human) ^addword(I am your father, end, 1)
s:(*) ^addword(hey, start, 1)

Execution

> hello
hey hello human I am your father
> how are you
hey I am fine and you

^replace¶

Syntax

s:(Answer) ^replace(Expression1, Expression2, Frequency)

Where:

Answer is the Robot output to be matched
Expression1 can be any string (word(s), concept...) you want to replace
Expression2 can be any string (word(s), concept...) you want to put instead of Expression1
Frequency is the probability of the skin to be applied (1:always, 0:never)

Usage

Replaces Expression1 with Expression2 in each Robot output matching the skin.

Conditions

The rule must be active.

Example

topic: ~introduction ()
language: English

u:(hello) hello human
u:(what do you like to do) I like to speak with you human
u:(do you want to play) yes human we can play together

s:({*} human {*}) ^replace(human, Michael, 1)
s:({*} speak {*}) ^replace(speak, play, 1)

If you are not familiar with {*} check: Wildcard: * to under Optional part: { }.

Execution

> hello human
hello Michael
> what do you like to do
I like to play with you Michael
> do you want to play
yes Michael we can play together

^defined_function¶

Syntax

^defined_function($parameter1, $parameter2, ..)

Usage

Allows you to use a function previously defined with def.

Example

topic: ~test()
language: English

def:greets($age) ^first["$age > 18 Mister" "kid"]

u:(I am _* years old) Hello ^greets($1)

Execution

Knowledge Management¶

All the following functions are applied in the “com.aldebaran.learning” domain.

Wildcard

You can use the wildcard ”?” (matching everything) for several functions such as contains, remove.

For example:

^containsKnowledge(?, color, blue)

Note that it is not the same wildcard as in ALKnolwedge, which use “*” as wildcard.

Knowledge functions¶

qiChat functions	ALKnowledge equivalent
^addKnowledge(subject, predicate, object)	`ALKnowledge::add`
^updateKnowledge(subject, predicate, object)	`ALKnowledge::update`
^containsKnowledge(subject, predicate, object)	`ALKnowledge::contains`
^notContainsKnowledge(subject, predicate, object)	Will give the opposite of ^contains.
^removeKnowledge(subject, predicate, object)	`ALKnowledge::remove`
^queryKnowledge(subject, predicate, object)	`ALKnowledge::query` Will return only the first element of the list of results

Example

topic: ~test()
language: English

concept:(color) [blue red green yellow]

# addKnowledge
u:(Bob likes the _~color color) Ok ^addKnowledge(bob, likes, $1)

# queryKnowledge
u:(which color does like Bob) ^first["He likes the ^queryKnowledge(bob, likes, ?)" "I don't know"]

# contains
u:(Does Bob like the _~color color) ^first["Yes ^containsKnowledge(bob, likes, $1)" "No he doesn't"]
u:(Does Bob like something) ^first["Yes ^containsKnowledge(bob, likes, ?)" "No he doesn't"]
u:(Does anyone like the _~color) ^first["Yes someone does ^containsKnowledge(?, likes, $1)" "Noone does"]

# removeKnowledge
u:(Bob does not like the _~color color ) Ok ^removeKnowledge(bob, likes, $1)
u:(Bob does not like anything) Ok ^removeKnowledge(bob, likes, ?)

# updateKnowledge
u:(Bob likes only the _~color) Ok ^updateKnowledge(bob, likes, $1)

Execution

# add and query
> Which color does like Bob
I don't know
> Bob likes the blue color
Ok
> Which color does like Bob
He likes the blue

# contains
> Does Bob like the blue color
Yes
> Does Bob like the red color
No he doesn't
> Does Bob like something
Yes
> Does anyone like the blue
Yes someone does

# query with several results
> Bob likes the red color
Ok
> Does Bob like the red color
Yes
> Which color does like Bob
He likes the blue
#Only on result is returned, if you use query(bob, likes, ?) from the module
# ALKnowledge (in python for instance) you would have get ['blue', 'red']

# update
> Bob likes only the green
Ok
> Which color does like Bob
He likes the green
> Does Bob like the red color
No he doesn't
> Does Bob like the blue color
No he doesn't

# remove (one and several triples)

> Bob does not likes the green color
Ok
> Does Bob like the green color
No he doesn't

> Bob likes the blue color
Ok
> Bob likes the red color
Ok

> Bob does not like anything
Ok
> Does Bob like the red color
No he doesn't
> Does Bob like the blue color
No he doesn't

"^containsKnowledge(Bob, place, theater) He is already there"
"He will be there at ^queryMetadata(Bob, place, theater, happeningDate)"
"I don't know"]

# setExpiringKnowledge
u:(Bob will leave the theater in 1 minutes) Ok ^setExpiringKnowledge(Bob, place, theater, ^currentDateTime + 00:01)
u:(Where is bob) ^first["He is at the ^queryKnowledge(Bob, place, ?)" "I don't know"]
