Personnalisation des entrepôts de données spatial par approche implicite

Dans ce travail, nous avons étudié le phénomène de l’accidentologie routière qui implique différents intervenants sollicitant une information pertinente répondant à leurs besoins spécifiques en un temps performant. Cependant et en raison de l’augmentation considérable du volume de données stocké dans les Entrepôts de Données Spatiales (EDS), délivrer l’information pertinente aux utilisateurs devient un enjeu crucial. De plus, ces utilisateurs sollicitent des analyses personnalisées qui facilitent leurs tâches quotidiennes de prise de décision. Ceci est réalisé en adaptant le système à leurs préférences qui sont regroupées dans une structure appelée profil utilisateur, concept fondamental dans un système de personnalisation.

Mots clés : Entrepôt de données Spatiale, SOLAP, accidentologie, personnalisation, profil utilisateur.

In this work, we have studied the phenomenon of road accident which involves various stakeholders seeking relevant information to meet their specific needs in a best time. However, and because of the considerable increase in the amount of data stored in Spatial Data Warehouses (SDW), delivering relevant information to users is becoming a critical issue. In addition, these users solicit personalized analysis that facilitates their daily decision- making tasks. This is done by adapting the system to their preferences that are grouped into a structure called a user profile, an essential concept in a customization system.

Keywords: Spatial Data Warehousing, SOLAP, accident, personalization, user profile.
