koreUtil Libraries

koreUtil libraries provide pre-written JavaScript functions which make common or complex tasks easy to implement. These libraries often target specific tasks such as setting up recurring rules for calendars, parsing and manipulation of dates, conversion of dates between timezones, tools to simplify programming with strings, numbers, arrays, functions, and objects, etc.

How to Use

koreUtil libraries can be used anywhere in the AI Agent where there is flexibility to write JavaScript code such as script node, message node, confirmation node, entity node, standard responses, answers to FAQs, small talk, event handlers, etc.

  ]
  

koreUtil.getCurrentOptions

koreUtil.getCurrentOptions is a platform-offered JS library that provides utility functions to get the current template for language selection standard response options. This can be used to customize the standard response. Post the release of v8.1, this function has been enhanced to return the authorization URL used in the standard response when end-user authorization is requested.

Following is the return format for each of the situations:

• For the language selection standard response:

  {"list_of_languages": [
        {"title": "English","value": "English"},
        {"title": "Deutsche","value": "Deutsche"},
        {"title": "Español","value": "Español"}
  ]}
  

• For the language ambiguity standard response:

  {"current_language": "Español",
     "list_of_new_languages": [
        {"title": "English","value": "English"},
        {"title": "Deutsche","value": "Deutsche"},
        {"title": "Español","value": "Español"}
     ]}
  

• For the language switch standard response: {"new_language": "Español","current_language": "English"}

• For User authorization request standard response:

  {
     "authorizationURL": "https:///r/xxxxxxxxxxxxx"
  }
  

Usage Example 1: To get the standard response for “Ask if the user would like to select any of the languages”:

var info = koreUtil.getCurrentOptions();
var message = {
   "type": "template",
   "payload": {
      "template_type": "button",
      "text": "please select your language",
      "subText": "Button Template Description",
      "buttons": []
   }
};
for (i = 0; i < info.list_of_languages.length; i++) {
   var button = {
      "type": "postback",
      "title": info.list_of_languages[i].title,
      "payload": info.list_of_languages[i].value
   };
   message.payload.buttons.push(button);
}
print(JSON.stringify(message));

Usage Example 4: To get the standard response for “User needs to authorize or re-authorize”:

var info = koreUtil.getCurrentOptions();
var message = {
   type: 'template',
   payload: {
      template_type: 'button',
      text: 'Please authorize before we continue...',
      buttons: [
      {
         type: 'url',
         title: 'Click here to authorize',
         url: info.authorizationURL
      }
      ]
   }
};
print(JSON.stringify(message));

koreUtil.getAmbiguousIntents

The koreUtil.getAmbiguousIntents util function is used to obtain the ambiguous intents list when the Ambiguity Intents Identified event gets triggered. Along with the list of ambiguous intents, the retrieved context object contains additional details such as ambiguity reasons and the engine name that detects the intent (ML, FM, or KG).

Sample Response:

{
"intents": [
   {
      "intent": "Transfer Money",
      "name": "Transfer Money",
      "intentType": "dialog",
      "mlScore": 100,
      "rrScore": 7980,
      "identifyingEngines": {
         "ml": true
         }
   },
   {
      "intent": "Pay Bills",
      "name": "Pay Bills",
      "intentType": "dialog",
      "rrScore": 0,
      "identifyingEngines": {
         "traits": true
      }
   }
],
"cause": "multipleChoices",
"userInput": "How do I make a payment or transfer"
}

koreUtil.getSessionId is a Platform offered JS library for obtaining the current conversation session ID.

Usage Example:

var sessionId = koreUtil.getSessionId();

koreUtil.closeConversationSession

koreUtil.closeConversationSession is a Platform function for force closing any active conversation. This function can be invoked from any component that supports JavaScript.

Usage Example:

koreUtil.closeConversationSession();

koreUtil.autoTranslate

koreUtil.autotranslate is a platform function that lets you automatically translate the AI Agent’s response from a language in which it’s configured to the language in which the user is interacting or a language of your choice.

To use the koreUtil.autoTranslate function for language translation, you must have the Access Key provided by your translation service provider, such as Google Translator, Microsoft Translator, etc.

Response Types	Components	Translation Behavior
Plain Text Responses	Refers to plain text responses defined anywhere in the application. For example, prompts, responses, etc.	Default: Auto-translated
Advanced / JavaScript based Responses	Refers to responses defined using JavaScript.	Default: No auto-translation
Auto-formatted Responses	Refers to the responses that are auto-formatted by the Platform as per the channel specifications.	Default: Auto-translated

Usage Example:

koreUtil.autoTranslate();

Use Case-1: To translate part of a sentence in the user’s language:

{{koreUtil.autoTranslate('Welcome! I am a virtual assistant powered by ')}} General Insurance

Use Case-3: To translate the bot responses in a particular language by passing the language code:

var message = koreUtil.autoTranslate("This is a sample message", "de");
print(message);

koreUtil.getFormDefinition

The koreUtil.getFormDefinition allows you to get the form definition, which consists of the form meta, form components, and form messages.

Usage Example:

let formDef = koreUtil.getFormDefinition();
