Annotation Tab

The Annotation tab is used to assign labels to a single token (referred to as a unigraph) or combination of two adjacent tokens (referred to as a digraph). A token is defined as an alphabetic or numeric sequence of characters in a description string. For example, the string "ABC vanilla yogurt 500gr" is a description that consists of the following five tokens (or unigraphs): "ABC", "vanilla", "yogurt", "500"and "gr". At the same time, it consists of the following digraphs: "ABC vanilla", "vanilla yogurt", "yogurt 500" and "500 gr".

The Annotation tab provides two screens to annotate unigraphs and digraphs.
