# RecogResultData

> Element recognition result data structure.

`RecogResultData` is typically returned as the `recognizeResult` field of [`Element`](/en/api-reference/supernote-plugin/types/trail). It describes the recognized category and key point location information.

## Purpose

You can treat this as a "recognition output summary", which typically includes:

* **Recognized category**: `predict_name` indicates which category the model/rules think the element belongs to (default: `others`).
* **Recognition region**: `up_left_point_*` and `down_right_point_*` form a bounding box that represents the region on the page.
* **Key point**: `key_point_*` is a representative anchor point used for later interactions or positioning.

<Note>
  These fields use pixel coordinates, which makes them convenient for direct UI display and interaction positioning.
