Résumé / Abstract
This paper focuses on interactive Knowledge Discovery pro-cesses in the context of understanding an activity from behavioural data. Data mining provides patterns experts have to interpret and synthesize as new knowledge. Discovering patterns is an analysis task while building new symbolic knowledge is a synthesis task. A previous trace based approach (Abstract) oered a rst answer to support analysis. This paper goes one step forward in supporting the synthesis task. We modify an algorithm of automata discovery in order to involve the user in the mining process, exploiting his expert knowledge about the observed activity. We chose the -algorithm (Van Der Aalst et al.) developed for Petri nets discovery in a work ow management context. The modi ed algorithm is described and illustrated, showing how to use intermediate data to converge interactively to a satisfying automata. Finally, we discuss the use of this approach to contribute to a new knowledge mining process.
