Task analysis is a critical step in the design process of interactive systems. The large set of task models available today may lead to the assumption that this step is well supported. However, very few task models are tool-supported. And in this latter category, few of them are based on a clear semantics (in this article, the word semantics is used with the following definition: ‘‘the meaning of a word, phrase, sentence, or text’’ from Compact Oxford English Dictionary ).
