Language for creating bots

Bot++

A language making it simple to write chat bots.

add state feeling
set feeling.trainingdata [
   "how are you?"
   "how do you do?"
]
set feeling.responses [
    "i'm fine thanks"
    "everything ok"
]

add state greetings
set greetings.trainingdata [
   "hello"
   "hi"
   "hallo"
   "good morning"
]
set greetings.responses [
   "nice to meet you"
   "hello"
   "hallo"
]

Define the state with "trainingdata" and possible "responses". The example creates a bot with 2 states (feeling and greetings) each state has some learning data and some possible replys. It looks limited now but with the tag-feature from Lookout complex conversations should't be problem.

Get started

see main.b++ in editor and

go run main.go

Example output for previous example

Entering REPL, type exit to quit
how are you
>>  everything ok
hello
>>  nice to meet you

Example output for main.b++

Entering REPL, type exit to quit
do you know the time
>>  its $time (variables yet to come)
book a flight
>>  whats your destination?
hamburg
>>  ok i'll book it for tomorrow
thanks
>>  a pleasure

(the flight state in this example is very limited and needs a lot of the Lookout features to work nicely )

Lookout

• language specs
• string interpolation with properties

  set greetings.responses [
    "hello from $name"
    "hello, its a beautiful $timeNow.weekday"
  ]
  

• improve string selection logic use fuzzy logic, use machine learning, hidden markov
• input / output tags tags conversations, if the user triggered the greeting state he gets the tag "polite_user"

  set greetings.outputTag polite_user
  

  only if the user was polite enough to greet the charming context is considered as valid state (filtered by inputTag)

  set charming.inputTag polite-user
  

  This makes it possible to build complex conversations. e.g. ask for flights -> book flights -> list flights
• a simple web interface to manage your bot(s):
  • Easy Slack & MS Teams integration
  • see bot logs (messages per second, failes pers seconds)
  • log exceptions
• switch between edit and talk mode in bot++ console application. Live tune your bot while your're talking to it
• data types for trainingdata

  add entity @weekday
  set @weekday.monday ["mondays","monday","mon"]
  set @weekday.tuesday ["tuesdays","tuesday","tues"]
  set greetings.trainingdata [
      "set alarm on %{mondays:@weekday:$weekday}"
  ]
  

  declares a variable $weekday of the type @weekday with the values: monday, tuesday
• string parsing for trainingdata prepares trainingdata to lookout for a username and sets the variable $username to bob if the user entered a similiar sentence

  set greetings.trainingdata [
      "hello my name is %{bob:@text:$username}"
  ]
  

• actions on state e.g. a http action:

  set feeling.action{
      http["https://myhost?flight=$bookedFlightNumber"]
  }
  

  sends a http request after on state enter. the http request return values can be used in the responses section
