The Context object is the container object that persists data for dialog execution and across all intents i.e. dialog tasks, action, alert & info tasks, and FAQs. Kore.ai’s natural language processing (NLP) engine populates the intent identified, entities extracted, and history into this object. Keys from the Context object are used in the dialog task and intent transition conditions. Also, the context object can be accessed with additional system and session variables.
The syntax when using an Context object key in a URL is to enclose the object name in double brackets as shown next:
https://quora.com/{{context.entities.topic}}/rss
The Context object can also be referenced in a script node as well as for dynamic values in an entity node and passed in the payload response to the Kore.ai SDK. You can update the Context object key values based on business logic to influence the dialog task execution.
| Note: The context object has a size limit of 1024 KB. The platform notifies the bot designers when the size of the context object exceeds the limit. We recommend you review these notifications and modify the bot definition to keep the context object size under the limit. In the upcoming releases, the platform will discard conversations if the context size exceeds the limit. |
The platform also creates and maintains Session Variables which can be referred to from here.
The following table describes the Context object keys. These can be classified into Global and Dialog contexts based on when they are created and populated. Refer here for details.
| Key | Category | Description | Usage Example |
|---|---|---|---|
| intent | Dialog | The intent recognized by the NLP interpreter. | Syntax: context.intent.<< intent name >> |
| entities | Dialog | An array of key/value pairs based on user prompts and recognized user input for those prompts. |
Syntax: var today = new Date();
if(today.getHours() < 21)
{
print("You have requested to transfer " +context.entities.Passenger +
" from " +context.entities.FromFlightNumber +
" to " +context.entities.ToFlightNumber + ". " +
" It will take 24h for your boarding pass to reflect the change. Shall I go ahead? ");
}
else
{
print("You have requested to transfer" +context.entities.Passenger +
" from " +context.entities.FromFlightNumbere +
" to " +context.entities.ToFlightNumber+ ". Shall I go ahead? " +
context.accdata[0].transfers.length);
}

| traits | Dialog | Traits set for the given context | |
| currentLanguage (introduced in ver7.1) |
Global | the current conversation language | |
| suggestedLanguages (introduced in ver7.1) |
Global | list of all languages detected by the platform from the user’s first utterance, presented in the order of confidence level. This will be reset at the start of each conversation. | |
| history | Global | An array that contains the nodeId for each component using the NLP interpreter. |
An array of objects defining the sequential and historical node path executed in the dialog flow.
|
| onHoldTasks | Dialog | an array of all tasks that are kept on hold while a conversation is in progress. This is a read-only list that you can use for evaluation purposes. (introduced in ver 7.1) | |
| service node name | Dialog | A collection of objects for Service node executions. |
|
| resultsFound | Dialog | True, if results are returned | |
| message_tone | Global | An array of recognized tone emotions and scores for the current node in a dialog task. |
|
| dialog_tone | Global | An array of average recognized tone emotions and scores for the entire dialog task session. |
|
| << nodename >>.response.body | Dialog | The HTTP JSON response from the Service node. | Syntax: context.<< node name >>.response.bodyIn the following code example, the response from a Service node is displayed to the end-user in a Message node. |
| Developer Defined Key | Dialog | A key/value pair defined by the developer. | Syntax: context.<< varName >>For example, context.customerId |
