Based on spatial data modeling, this paper attempts to find a theoretical foundation for SVG-based spatial information representation. Then we propose an SVG-based spatial information representation model for spatial data publishing.

In this paper, we adopt an interactional perspective on context: 1) Something is context because it is used for adapting the interaction between the human and the current system. 2) Activity is central to context. 3) Context differs in each occasion of the activity.

Currently, providing context-aware services/information is still very challenging in mobile guides. Collaborative filtering (CF), known as “Amazon-like recommendations”, is a promising solution for providing context-aware recommendations. The paper investigates how context-aware CF (CaCF) can be introduced into mobile guides.

In this paper, an evaluation framework which combines the key aspects of indoor navigation for investigating mobile indoor navigation systems is proposed.
