Abstract


The virtual approach of information integration, called mediation, suffers from the slowness response to user queries and the risk of sources unavailability. To cure these problems, some information may be stored at the mediator level. However, the success of this solution depends on selecting the right set of information to materialize. This task should be automated when the collection of data sources is large and evolving. Existing methods for the selection of information to materialize have some drawbacks and do not always give feasible or optimal results. Therefore, we propose a new approach based on fuzzy logic, which we call FULVIS.
