PLIS+: A Rule-Based Personalized Location Information System

In this paper, the idea of providing personalized, location-based information services via rule-based policies is demonstrated. After a short introduction, an innovative Personalized Location Information System (PLIS+) is designed and implemented. PLIS+ delivers personalized and contextualized information to users according to rule-based policies. More specifically, many categories of points of interest (for example shops, restaurants) have rule-based policies to expose and deploy their marketing strategy on special offers, discounts, etc. PLIS+ evaluates these rules on-the-fly and delivers personalized information according to the user’s context and the corresponding rules fired within this context. After discussing the design and the implementation of PLIS+, illustrative examples of PLIS+ functionality are presented. As a result, PLIS+ proves that combining contextual data and rules can lead to powerful personalized information services.
