Semantic Trajectories: Mobility Data Computation and Annotation

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

With the large-scale adoption of GPS equipped mobile sensing devices, positional data generated by moving objects (e.g., vehicles, people, animals) are being easily collected. Such data are typically modeled as streams of spatio-temporal (x,y,t) points, ca ...

Semantic Trajectories Modeling and Analysis

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

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

Stefano Spaccapietra, Christine Parent, Karl Aberer, 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 ...

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 ...

A knowledge infrastructure for intelligent query answering in location-based services

Stefano Spaccapietra, Shijun Yu

Intelligent query answering in Location-based Services refers to their capability to provide mobile users with personalized and contextualized answers. Personalization is expected to lead to answers that better match user's interests, as inferable from the ...

Automatic Construction and Multi-level Visualization of Semantic Trajectories

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

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 ...

Reasoning with large ontologies stored in relational databases: The OntoMinD approach

Stefano Spaccapietra, Christine Parent

A major obstacle to the development of ontologies in support of the Semantic Web is the poor capability of current ontology techniques to handle very large ontologies, in particular regarding scalability of reasoners. This paper builds on the assumption th ...

Advanced Data Mining Method for Discovering Regions and Trajectories of Moving Objects: "Ciconia ciconia" Scenario

Stefano Spaccapietra, Claudio Magalhaes Carneiro

Trajectory data is of crucial importance for a vast range of applications involving analysis of moving objects behavior. Unfortunately, the extraction of relevant knowledge from trajectory data is hindered by the lack of semantics and the presence of error ...

Evolving Objects in Temporal Information Systems

Stefano Spaccapietra, Christine Parent

This paper presents a semantic foundation of temporal conceptual models used to design temporal information systems. We consider a modelling language able to express both timestamping and evolution constraints. We conduct a deeper investigation of evolutio ...
