Towards a Semantic Indoor Trajectory Model

Alexandros Kontarinis, Karine Zeitouni, Claudia Marinica, Dan Vodislav, Dimitris Kotzinos
2019 Zenodo  
Motivated by a compelling museum case study, and by what we perceive as a lack in indoor trajectory research, we are interested in combining aspects of state-of-the art semantic outdoor trajec- tory models  ...  , with a semantically-enabled hierarchical symbolic representation of the indoor space, which abides by OGC's In- doorGML standard.  ...  This work is supported by the TRAJECTOIRES project funded by the French Heritage Science Foundation (EUR-17-EURE-0021).  ...

Iraklis Varlamis, Konstantinos Tserpes, Mohammad Etemad, Amílcar Soares Júnior, Stan Matwin
2019 Zenodo  
In this article, we present a methodology for creating a network abstraction of the trajectories of multiple vessels, which uses only the information collected from the vessels' Automatic Identification  ...  Experimental results on a real dataset demonstrate some of the capabilities of the proposed network model and indicate its extension to more complex automatic surveillance tasks.  ...  ACKNOWLEDGEMENTS This work has been developed in the frame of the MASTER project, which has received funding from the European Union' s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie  ...
