Widgets of this category take *Segmentation* data in input and emit data of
-the same type. Some of them (:doc:`Preprocess <preprocess>` and
-:doc:`Recode <recode>`) generate modified text data. Others
-(:doc:`Merge <merge>`, :doc:`Segment <segment>`, :doc:`Select <select>`,
-:doc:`Intersect <intersect>` and :doc:`Extract XML <extract_xml>`) do not
-generate new text data but only new *Segmentation* data.
-:doc:`Display <display>`, finally, is mainly used to visualize the details of
-a given *Segmentation* object (content and address of segments, as well as
-their possible annotations).
