Maintenance of association rules is an interesting problem. Several incremental maintenance algorithms were proposed since the work of (Cheung et al, 1996). The majority of these algorithms maintain rule bases assuming that support threshold doesn't change. In this paper, we present incremental maintenance algorithm under support threshold change. This solution allows user to maintain its rule base under any support threshold.

Geographic Information Systems (GIS) are widely used in different domains of applications, such as maritime navigation, museums visits and route planning, as well as ecological, demographical and economical applications. Nowadays, organizations need sophisticated and adapted GIS-based Decision Support System (DSS) to get quick access to relevant information and to analyze data with respect to geographic information, represented not only as spatial objects, but also as maps. Several research works on GIS personalization was proposed: Face the great challenge of developing both the theory and practice to provide personalization GIS visualization systems. This paper aims to provide a comprehensive review of literature on presented GIS personalization approaches. A benchmarking study of GIS personalization methods is proposed. Several evaluation criteria are used to identify the existence of trends as well as potential needs for further investigations.
