Here are the key components of architecture:

Deploy Lex bot and Alexa backend function using Java

You need to install org.sample.aws.lex:lex-java:0.2 dependency as explained at https://github.com/arun-gupta/lex-java#install-jar-locally before building this project.

mvn -f starwars-chatbot/pom.xml clean package install

ARN for Alexa function: aws lambda get-function --function-name StarWarsChatbot --region us-east-1 | jq .Configuration.FunctionArn

Note	Getting Started with Alexa skill using Java is explained at https://github.com/arun-gupta/alexa-skill-java.

  "force-side": "light",
  "id": 1,
  "lightsaber": "green",

    "When nine hundred years old you reach, look as good you will not.",
    "Truly wonderful, the mind of a child is",
    "A Jedi uses the Force for knowledge and defense, never for attack",
    "That is why you fail.",
    "Adventure. Excitement. A Jedi craves not these things.",
    "Judge me by my size, do you?",
    "Fear is the path to the dark side",
    "Wars not make one great",
    "Do, or do not. There is no try",
    "Size matters not",
    "The dark side clouds everything",
    "Impossible to see the future is",
    "Clear your mind must be",
    "Much to learn you still have ... my old padawan"
  ],
  "weapon": "lightsaber",

chatbot's Issues

new utterance for home planet

what is yoda's home planet
Which character
what is yoda's planet
Which character

CI/CD pipeline using CodePipeline

CI/CD pipeline for Chatbot using CodePipeline

Add a web application interface to Lex bot

Publish Alexa Skill

Publish the Alexa Skill so that is publicly accessible

Clarify the prompt for incorrect answers in multi-turn conversation

Instead of repeating the question for an incorrect answer, add a prompt indicating that the answer was incorrect and then repeat the question

Add a conversation that shows intent chaining

Add a conversation that shows intent chaining. For example:

Give me a couple of Han solo quotes <ANSWER>
Would you like to know his light saber color? <ANSWER>

Several characters are not recognized for Alexa skill

For example:

tell me a kylo ren quote gives an error for Alexa skill:

{
  "version": "1.0",
  "response": {
    "outputSpeech": {
      "text": "Are you sure kylo Ren was in Star Wars?",
      "type": "PlainText"
    },
    "card": {
      "content": "Star Wars Quotes",
      "title": "Are you sure kylo Ren was in Star Wars?"
    },
    "reprompt": {
      "outputSpeech": {
        "text": "Are you sure kylo Ren was in Star Wars?",
        "type": "PlainText"
      }
    },
    "speechletResponse": {
      "outputSpeech": {
        "text": "Are you sure kylo Ren was in Star Wars?"
      },
      "card": {
        "content": "Star Wars Quotes",
        "title": "Are you sure kylo Ren was in Star Wars?"
      },
      "reprompt": {
        "outputSpeech": {
          "text": "Are you sure kylo Ren was in Star Wars?"
        }
      },
      "shouldEndSession": false
    }
  },
  "sessionAttributes": {}
}

Add multi-turn conversations

Add an utterance that requires a conversation with the user. For example, bot may ask for missing data in an utterance with multiple slots.

Force intent not working for Kylo Ren

What side of the force was Kylo Ren on
An error has occurred: Invalid Lambda Response: Received error response from Lambda: Unhandled
What side of the force was Yoda on
Yoda was on the light side, and so was a Jedi

Improve error message for a character not in database

For example:

tell me a admiral ackbar quote
Which character

Character names should be case insensitive

ask me a line question
Who said "Clear your mind must be"
yoda
Who said "Clear your mind must be"
Yoda
Yep, you're right!

Another fail case:

Who said "You can run, but you'll only die tired"
boba FETT
Who said "You can run, but you'll only die tired"
Boba Fett
Yep, you're right!

Lightsaber color response needs to be improved

what is the color of Leia lightsaber
Princess Leia's ligthsaber is null

The response should be something like:

Princess Leia does not have a ligthsaber

new utterance for force side

Works:

was kylo ren a jedi or a sith
Kylo Ren was on the dark side, and so was a Sith

Does not work:

was kylo ren a jedi
Kylo Ren is from the planet Chandrila

Aggressive scan of DynamoDB table

Scanning DynamoDB table returns only 1MB of data. Need to aggressively scan and return an accurate count in DBUtil.

Sample utterances for chatbot

@AdityaGupta1 to provide a list of initial utterances for Star Wars questions

Don't close application after answering question

When returning a SpeechletResponse, call its setShouldEndSession(false) to prevent the application from closing. Then, you can re-prompt the user and say something like "Would you like me to ask you another question?".

Additional information in the response could be confusing

Was Yoda on the Light or Dark side of the force
Yoda was on the light side, and so was a Jedi
Was yoda affiliated with the Jedi or the Sith
Yoda was on the light side, and so was a Jedi

The response should return only the information asked in the question

what side of the force is han solo on
Han Solo was on the light side, and so was a Jedi

Admiral Ackbar
Jar jar binks
Anakin Skywalker

Enable alternate names for different characters

For example, Luke and Luke Skywalker should be recognized as alternates

"Ask me a line" with Twilio/SMS throws NPE

java.lang.NullPointerException: java.lang.NullPointerException
java.lang.NullPointerException
at org.sample.aws.chatbot.starwars.lex.StarWarsLexBot.handleRequest(StarWarsLexBot.java:41)
at org.sample.aws.chatbot.starwars.lex.StarWarsLexBot.handleRequest(StarWarsLexBot.java:16)

Planet response needs to be improved

what planet is yoda from
Yoda's planet is null

The response should be:

Yoda's planet is not known

Here is a quote from Luke Skywalker: I won't fail you. I'm not afraid.

Should be

Here is a quote from Luke Skywalker: "I won't fail you. I'm not afraid."
