During the month of August researchers Alessandra Raffaetá and Marta Simeoni from UNIVE have been seconded to Dalhousie University in Halifax Canada. During the secondment UNIVE researchers worked with with Dr. Jay Kumar, post-PhD fellow at the Institute for Big Data Analytics. The main goal was to improve the results already obtained for the fishing effort forecast in the Northern Adriatic Sea. The area of the Northern Adriatic Sea is known to be intensively fished and the fishing effort is a key indicator for monitoring the fishing pressure on an area of interest over time. Hence, accurate fishing effort forecast could help in monitoring the fishing pressure at the basin level and in preventing overexploitation.
In July and August 2022 four secondments took place at PUC in Rio de Janeiro: three secondment from CNR - Beatrice Rapisarda, Chiara Renso and Raffaele Perego - and one from UNIVE - Andrea Marin. We have discussed with Prof. Casanova hosting us tat the wonderful forest of the PUC premises about our current activities and specifically on RDF data and semantic enrichment.
During the month of April the CNR secondee Francesco Lettich visited our partner Jose de Macedo at the Federal University of Ceará in Brazil for executing a one month secondment. The research work of Francesco focussed on WP4 and specifically on external sensor trajectories (ESTs), i.e. sparse trajectories collected through the observations of a sensor network deployed within some urban area. One particular issue is the need to enrich ESTs with further features, as this has the potential to substantially improve the accuracy of predictive techniques. In this context the CNR staff can offer its expertise in the semantic enrichment domain, with the integration of existing techniques or the introduction of novel ones.
Prof. Kofidis from University of Piraeus (Greece) executed his secondment to Dalhousie University in Canada during the month of February 2020. The research topic of prof. Kofidis is the application of multi-way arrays (aka tensors) and their (coupled) decomposition to holistic trajectories. These models have been recently shown to outperform more conventional models and methods, and result in highly effective tools for applications such as recommendation and prediction.
Prof. Ronaldo Mello from Federal University of Santa Catarina is visiting Harokopio University in Athens. They are working hard in defining extensions to the MASTER conceptual model extensions for data analytics. We see in the picture Christos Sardianos, Antonios Makris, Ronaldo Mello, Iraklis Varlamis, Yannis Kontopoulos, Konstantinos Tserpes.
