The French-speaking EGC congress gathered scholars since 2001 to tackle issues on knowledge discovery and management. EGC questions its history and future in the « défi EGC » challenge. Our lexico-scientometric approach sheds the light on the topics and related venues favourited by its contributing authors. We identify those active scholars who are seldom invited as PC members by relating data from the program committees and authorships. Our results are featured in a decision support system showcasing the activities of the EGC association.
