“…The procedure have a subgoal structure that provides its semantic. For instance, while the sequence of actions for the Tower Of Hanoi is as follows, Traditionally tasks are modeled using such a tree-like subgoals structure [10], [11] with logical (IF, OR, XOR …) and temporal (No order, Same time, Until ...) operators (or constructors) that indicate time relationships between subgoals. The set of sub-goals has a hierarchical structure: highevel sub-goals are found at the top of the tree while the observable action units (primitive) are at the leaf nodes.…”

By defining Know-How and considering the collection of relevant data, we provide a computational cognitive model that is based on the problem-solving and task-analysis literature. The model is of help for the conception of an automatic assessment system of Skills acquisition related to Know-How. The platform we are building is implementing the method as part of the "Know-How Digital Campus" project (KH-DC).

Some years ago, progress in road telematics had made it possible to introduce time travel information in real time on VMS devices. Such information can lead road users to avoid congested areas as well as to waiting in a better condition for the end of the congestion. In a way, they increase congestion, in another way, they reduce it. Our research aimed at explaining the reasons why some people behave in a way and another one in. We assumed that travel time messages may be interpreted from several points of view, depending on driver knowledges in memory, experience and will, and as a result, the decision taken. An enquiry on a group of drivers aimed at analysing mental activity involved in decision taking process will be presented.

“…The Galois lattice formalises how sets of objects are related to sets of properties, in embedded formal concepts. The Galois lattice of a binary relation (Barbut & Monjardet, 1970) is a hierarchical algebraic structure that has been used to investigate categorisation problems (Bernard & Poitrenaud, 1999;Gue´noche & Van Mechelen, 1993;Poitrenaud 1995;Storms, Van Mechelen, & De Boeck, 1994). Given a set of objects and a set of properties, we can build a binary relation composed of the set of all the object -property couples.…”

We re-evaluate existing data that demonstrate a large amount of variability in the content of categories considering the fact that these data have been obtained in a specific task: the production of features of single isolated categories. We present new data that reveal a large consensus when participants have to judge whether or not a given feature is characteristic of a category and we show that classification tasks produce an intermediate level of consensus. We argue that the differences observed between tasks are due to the extent of implied context and we propose a reinterpretation of typicality effects, demonstrating that they are compatible with the existence of a stable conceptual core. In order to explain how the existence of a conceptual core is consistent with variability due to context, we present a theory of categorisation based on a property tree organisation. Within a domain of description, we distinguish between semantic implications (flying ? moving) and empirical implications (flying ? having wings) as well as between properties used to describe objects. Semantic implications serve to build property lines and Galois lattices are used to reveal category structures according to empirical implications. We show that variability in the category content may be explained by the fact that some properties are emphasised while others are masked according to the context.
