Knowledge Base Question Answering for Space Debris Queries

1 code implementation31 May 2023 Paul Darm, Antonio Valerio Miceli-Barone, Shay B. Cohen, Annalisa Riccardi

In this work we present a system, developed for the European Space Agency (ESA), that can answer complex natural language queries, to support engineers in accessing the information contained in a KB that models the orbital space debris environment.

Optimisation of non-pharmaceutical measures in COVID-19 growth via neural networks

no code implementations16 Jun 2020 Annalisa Riccardi, Jessica Gemignani, Francisco Fernández-Navarro, Anna Heffernan

This study seeks to quantify the impact of government actions in mitigating viral transmission of SARS-CoV-2 by a novel soft computing approach that makes concurrent use of a neural network model, to predict the daily slope increase of cumulative infected, and an optimiser, with a parametrisation of the government restriction time series, to understanding the best set of mitigating actions.
