$entities

The $entities variable contains the list of all CAILA entities recognized in the user request.

The value of this variable is an array of objects having the following structure:

[
    {
        "pattern": "fruit",
        "startPos": 1,
        "length": 1,
        "value": "{\n    \"name\": \"banana\",\n    \"type\": \"fruit\"\n}"
    }
]

• pattern — the entity name.

• startPos — the position of the word from which the entity starts. The numbering starts from zero.

• length — the number of tokens that make up the entity.

• value — the entity reference data (DATA).

  The value always has a string type, even if you have specified JSON in DATA. Use the JSON.parse method in the script to convert a string into an object and access its properties.

If the user request matches an intent with slot filling, the objects in the $entities array will have an additional slot property — the name of the slot matched by the entity.
