Semantic Trajectories Modeling and Analysis

Stefano Spaccapietra, Christine Parent, Zhixian Yan, Maria Luisa Damiani, José Antonio Fernandes de Macedo

Focus on movement data has increased as a consequence of the larger availability of such data due to current GPS, GSM, RFID, and sensors techniques. In parallel, interest in movement has shifted from raw movement data analysis to more application-oriented ...

SeMiTri: A Framework for Semantic Annotation of Heterogeneous Trajectories

Karl Aberer, Stefano Spaccapietra, Christine Parent, Zhixian Yan, Dipanjan Chakraborty

GPS devices allow recording the movement track of the moving object they are attached to. This data typically consists of a stream of spatio-temporal (x,y,t) points. For application purposes the stream is transformed into finite subsequences called {\em tr ...

Adding Meaning to Your Steps (Keynote Paper)

Stefano Spaccapietra, Christine Parent

Mobility data is becoming an important player in many application domains. Many techniques have been elaborated to extract statistical knowledge from the data sets gathering raw data tracks about the moving objects of interest to an application. These data ...

A Hybrid Model and Computing Platform for Spatio-Semantic Trajectories

Stefano Spaccapietra, Christine Parent, Zhixian Yan, Dipanjan Chakraborty

In this paper, we propose a hybrid spatio-semantic model and a computing platform for trajectories of moving objects. Our hybrid model can represent trajectories in terms of both spatio and semantic mobility characteristics, supporting different levels of ...

Automatic Construction and Multi-level Visualization of Semantic Trajectories

Karl Aberer, Stefano Spaccapietra, Christine Parent, Zhixian Yan, Dipanjan Chakraborty, Lazar Spremic

With the prevalence of GPS-embedded mobile devices, enormous amounts of mobility data are being collected in the form of trajectory - a stream of (x,y,t) points. Such trajectories are of heterogeneous entities - vehicles, people, animals, parcels etc. Most ...

An application of advanced spatio-temporal formalisms to behavioural ecology

Stefano Spaccapietra, Christine Parent

There is great potential for the development of many new applications using data on mobile objects and mobile regions. To promote these kinds of applications advanced data management techniques for the representation and analysis of mobility-related data a ...

A Conceptual View on Trajectories

Stefano Spaccapietra, Christine Parent, Christelle Vangenot, Maria Luisa Damiani, José Antonio Fernandes de Macedo

Analysis of trajectory data is the key to a growing number of applications aiming at global understanding and management of complex phenomena that involve moving objects (e.g. worldwide courier distribution, city traffic management, bird migration monitori ...
