Spatiotemporal Behavior Profiling: A Treasure Hunt Case Study

Abstract

Abstract. Trajectories have been providing us with a wealth of derived information such as traffic conditions and road network updates. This work focuses on deriving user profiles through spatiotemporal analysis of trajectory data to provide insight into the quality of information provided by users. The presented behavior profiling method assesses user participation characteristics in a treasurehunt type event. Consisting of an analysis and a profiling phase, analysis involves a timeline and a stay-point analysis, as well as a semantic trajectory inspection relating actual and expected paths. The analysis results are then grouped around profiles that can be used to estimate the user performance in the activity. The proposed profiling method is evaluated by means of a student orientation treasurehunt activity at the University of Twente, The Netherlands. The profiling method is used to predict the students' gaming behavior by means of a simple team type classification, and a feature-based answer type classification.

Automated semantic trajectory annotation with indoor point-of-interest visits in urban areas

“…To collect validation data, we set up an experiment similar to the one described in [2]. During the welcome week of the University of Twente, called the Kick-In, the new students were invited to participate in a treasure hunt-like game that lasted four hours.…”

“…This makes trajectory data a promising source to determine personal preferences and needs, as discussed in [1]. Furthermore, trajectory data can be used to assess the trustworthiness of UGC, as discussed in [2]: a negative review of a restaurant that the user visited in the past week can probably be trusted more than a negative review of a person who works at a nearby competitor. Before we can perform such an analysis, we need to know which places were visited.…”
