  Taaable is a case-based reasoning system that adapts cooking recipes to user
constraints. Within it, the preparation part of recipes is formalised as a
graph. This graph is a semantic representation of the sequence of instructions
composing the cooking process and is used to compute the procedure adaptation,
conjointly with the textual adaptation. It is composed of cooking actions and
ingredients, among others, represented as vertices, and semantic relations
between those, shown as arcs, and is built automatically thanks to natural
language processing. The results of the automatic annotation process is often a
disconnected graph, representing an incomplete annotation, or may contain
errors. Therefore, a validating and correcting step is required. In this paper,
we present an existing graphic tool named \kcatos, conceived for representing
and editing decision trees, and show how it has been adapted and integrated in
WikiTaaable, the semantic wiki in which the knowledge used by Taaable is
stored. This interface provides the wiki users with a way to correct the case
representation of the cooking process, improving at the same time the quality
of the knowledge about cooking procedures stored in WikiTaaable.
