Simple entity

[!INCLUDE deprecation notice]

A simple entity is a generic entity that describes a single concept and is learned from the machine-learning context. Because simple entities are generally names such as company names, product names, or other categories of names, add a phrase list when using a simple entity to boost the signal of the names used.

The entity is a good fit when:

• The data aren't consistently formatted but indicate the same thing.

Example JSON

In the previous utterance, Bob Jones is labeled as a simple Customer entity.

The data returned from the endpoint includes the entity name, the discovered text from the utterance, the location of the discovered text, and the score:

This is the JSON if verbose=false is set in the query string:

"entities": {
    "Customer": [
        "Bob Jones"
    ]
}```

This is the JSON if `verbose=true` is set in the query string:

```json
"entities": {
    "Customer": [
        "Bob Jones"
    ],
    "$instance": {
        "Customer": [
            {
                "type": "Customer",
                "text": "Bob Jones",
                "startIndex": 0,
                "length": 9,
                "score": 0.9339134,
                "modelTypeId": 1,
