In this paper, we presenting an approach of mapping for mediation systems, an operation that is used to define and describe all the links between the elements of global schema and those of local schemas. To this end, we firstly presenting our approach to mapping that consist to defining and associates for each link between two elements the weight that reflects the degree of its existence by using an analysis of two components: syntactic and semantic. On the other hand, we integrate a set of functionality for source schemas with elements of complex types.}, isbn = {978-0-7354-1283-5}, issn = {0094-243X}, doi = {10.1063/1.4907842}, author = {El Yazidi, Moulay Hafid and Zellou, Ahmed and Idri, Ali}, editor = {Giannakopoulos, G and Sakas, DP and KyriakiManessi, D} } @conference { ISI:000350287800039, title = {A New Approach of Mapping}, booktitle = {2013 3RD INTERNATIONAL SYMPOSIUM ISKO-MAGHREB}, year = {2013}, note = {ISKO-Maghreb 3rd International Symposium, Marrakech, MOROCCO, NOV 08-09, 2013}, publisher = {ISKO}, organization = {ISKO}, abstract = {Data integration involves combining data residing in different sources, and providing the user a unified view of this data.

The problem of designing data integration systems is important in current applications of real world, especially for mapping between attributes of global schema and those of local schemas of sources. The question is how to link the global schema and the set of local schemas of sources. In this paper, we focus on studying the mapping approaches, more precisely the Global As View GAV approach (GAV) for schemas mapping. Also, we present a new approach of mapping for mediation systems, based on fuzzy logic. This new approach enjoys the benefits and advantages of fuzzy sets theory.}, isbn = {978-1-4673-4766-2}, author = {El Yazidi, Moulay Hafid and Zellou, Ahmed and Idri, Ali}, editor = {Essaaidi, M and Nemiche, M} }
