In this paper, we introduce a concept of in-situ AR mashup content (AMC) as a new type of end-user created content for AR applications and as a concentrated digital trace that re-veals Social and Community Intelligence (SCI). Especially, we present an AMC-based application for an art gallery that focuses on a specific representation format for AMC and the underlying architecture that enables such user participation.

We propose a smart recommendation for highly effcient and balanced itineraries based on multiple user-generated GPS trajectories. Users only need to provide a minimal query composed of a start point, an end point and travel duration to receive an itinerary recommendation.
