Abstract :
To find the right partners requires not only in private life big efforts. Concretely we are forced to solve this issue in building Virtual Networks for organizing tourism events. To solve these problems organizations must tackle two main challenges, the first one concern about the collaboration behavior, and the second one about tourism offers. Collaboration Agents, which are based on Semantic Web and Ontology, could solve these challenges. ECOLEAD, which was introduced in the ENTER conference (see [Withalm, Wolfel, 2005]), undertakes great endeavors to solve issues for Collaboration Networks. Collaboration Agents, which will be implemented by service providers on behave of an event organizer, will be roaming through the web, looking for appropriate partner, and evaluating their collaboration and tourism offers.
