Abstract-The exhibition industry has showed steady growth in both terms of size of an exhibition and the amount of money it generates. As the ubiquitous environment, there is much useful information for inferring visitors’ preference. However, the development and provision of such services have and taken account of the preferences and interests of visitors. For satisfaction of visitors, exhibitions need to meet the needs for personalization. Therefore, we suggest a personalized booth recommendation methodology for real –time exhibition guidance in ubiquitous exhibition environment. In a computer supported ubiquitous learning environment, visitors’ booth yisiting path can play a key role for reasoning visitors’ preference. In this study, by considering the booth visiting path of targed visitoris, we expect to reflecet visitors’ dynamic preference so that have improved accuracy compared to traditional collaborative filtering. Moreover, as we suggest a simple algorithm for fast predictions in recommender systems, we can also solve sclability problems.
