Traceability
Résumé
Traceability or keeping trace is used increasingly in the food industry after several hygiene and health problems, for instance mad cow disease. The use of activity traces are also developed in knowledge engineering and especially experience recognition by adapting case‐based reasoning through experience‐based reasoning. This chapter defines the notion of a trace, and presents an overview of profiling techniques and experience‐based reasoning. It deals with digital information traces. In crisis management, several actors perform several actions from different organizations. Several techniques have been developed in order to share information in an organization. Quick place and MS Share point were the first tools developed in order to tackle document sharing. These techniques are linked to activities, for instance Quick place is linked to Lotus Notes, which handles workflows in a company, and MS Share point is linked to MS Project, which helps to represent the organization of a project.
