Abstract

Knowledgable Location-based Services (LBS) aim at enab- ling mobile users to specify their requests and profiles on the move and providing them with context-aware and personalized local information relevant to their current activity and request. Therefore, it opens up new challenges in data infrastructure, knowledge representations and data management etc. In this paper, firstly we will discuss the characteristics of LBS in terms of data management, and then present our data architecture. Finally, we will explain how the knowledge is incrementally set up and maintained in a modular manner.
