# Separator hypothesis

> Properties of a Separator hypothesis — Orientation, Relative length, Space length, and Orthogonal shift in an Extraction Rules activity.

When a hypothesis is formulated, only those Separator objects that have been detected during pre-recognition are considered.

## Separator hypothesis properties

A formulated Separator hypothesis has the following type-specific properties (in addition to the general ones):

| Property | Description |
| :- | :- |
| Orientation | Specifies the orientation of the detected separator. |
| Relative length | Specifies the relative length of the detected separator. |
| Space length | Specifies the absolute length of the space character inside the detected separator. |
| Relative space length | Specifies the relative length of the space character inside the detected separator. |
| Orthogonal shift | Specifies the distance between separators (in the direction perpendicular to their orientation) in the hypothesis. |
