Each test is personalized for each student and is composed of a series of questions, classified on different domains (e.g. maths, science, logic, etc.). Since each test is unique for composition, it is crucial to guarantee a similar level of difficulty for all the tests in a session. For this reason, to each question, it is assigned a level of difficulty from a domain expert. Thus, the general difficultness of a test depends on the correct classification of each item. We propose two approaches to detect outliers. A visualization-based approach using dynamic filter and responsive visual widgets. A data mining approach to evaluate the performance of the different questions for five years. We used clustering to group the questions according to a set of performance indicators to provide labeling of the data-driven level of difficulty. The measured level is compared with the a priori assigned by experts. The misclassifications are then highlighted to the expert, who will be able to refine the question or the classification. Sequential pattern mining is used to check if biases are present in the composition of the tests and their performance. This analysis is meant to exclude overlaps or direct dependencies among questions. Analyzing co-occurrences we are able to state that the composition of each test is fair and uniform for all the students, even on several sessions. The analytical results are presented to the expert through a visual web application that loads the analytical data and indicators and composes an interactive dashboard. The user may explore the patterns and models extracted by filtering and changing thresholds and analytical parameters.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>13</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Pietro Bonato</style></author><author><style face="normal" font="default" size="100%">Paolo Cintia</style></author><author><style face="normal" font="default" size="100%">Francesco Fabbri</style></author><author><style face="normal" font="default" size="100%">Daniele Fadda</style></author><author><style face="normal" font="default" size="100%">Fosca Giannotti</style></author><author><style face="normal" font="default" size="100%">Pier Luigi Lopalco</style></author><author><style face="normal" font="default" size="100%">Sara Mazzilli</style></author><author><style face="normal" font="default" size="100%">Mirco Nanni</style></author><author><style face="normal" font="default" size="100%">Luca Pappalardo</style></author><author><style face="normal" font="default" size="100%">Dino Pedreschi</style></author><author><style face="normal" font="default" size="100%">Francesco Penone</style></author><author><style face="normal" font="default" size="100%">S Rinzivillo</style></author><author><style face="normal" font="default" size="100%">Giulio Rossetti</style></author><author><style face="normal" font="default" size="100%">Marcello Savarese</style></author><author><style face="normal" font="default" size="100%">Lara Tavoschi</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Mobile phone data analytics against the COVID-19 epidemics in Italy: flow diversity and local job markets during the national lockdown</style></title></titles><dates><year><style  face="normal" font="default" size="100%">2020</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://arxiv.org/abs/2004.11278</style></url></web-urls></urls><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Understanding collective mobility patterns is crucial to plan the restart of production and economic activities, which are currently put in stand-by to fight the diffusion of the epidemics. In this report, we use mobile phone data to infer the movements of people between Italian provinces and municipalities, and we analyze the incoming, outcoming and internal mobility flows before and during the national lockdown (March 9th, 2020) and after the closure of non-necessary productive and economic activities (March 23th, 2020). The population flow across provinces and municipalities enable for the modelling of a risk index tailored for the mobility of each municipality or province. Such an index would be a useful indicator to drive counter-measures in reaction to a sudden reactivation of the epidemics. Mobile phone data, even when aggregated to preserve the privacy of individuals, are a useful data source to track the evolution in time of human mobility, hence allowing for monitoring the effectiveness of control measures such as physical distancing. We address the following analytical questions: How does the mobility structure of a territory change? Do incoming and outcoming flows become more predictable during the lockdown, and what are the differences between weekdays and weekends? Can we detect proper local job markets based on human mobility flows, to eventually shape the borders of a local outbreak?</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Paolo Cintia</style></author><author><style face="normal" font="default" size="100%">Daniele Fadda</style></author><author><style face="normal" font="default" size="100%">Fosca Giannotti</style></author><author><style face="normal" font="default" size="100%">Luca Pappalardo</style></author><author><style face="normal" font="default" size="100%">Giulio Rossetti</style></author><author><style face="normal" font="default" size="100%">Dino Pedreschi</style></author><author><style face="normal" font="default" size="100%">S Rinzivillo</style></author><author><style face="normal" font="default" size="100%">Bonato, Pietro</style></author><author><style face="normal" font="default" size="100%">Fabbri, Francesco</style></author><author><style face="normal" font="default" size="100%">Penone, Francesco</style></author><author><style face="normal" font="default" size="100%">Savarese, Marcello</style></author><author><style face="normal" font="default" size="100%">Checchi, Daniele</style></author><author><style face="normal" font="default" size="100%">Chiaromonte, Francesca</style></author><author><style face="normal" font="default" size="100%">Vineis , Paolo</style></author><author><style face="normal" font="default" size="100%">Guzzetta, Giorgio</style></author><author><style face="normal" font="default" size="100%">Riccardo, Flavia</style></author><author><style face="normal" font="default" size="100%">Marziano, Valentina</style></author><author><style face="normal" font="default" size="100%">Poletti, Piero</style></author><author><style face="normal" font="default" size="100%">Trentini, Filippo</style></author><author><style face="normal" font="default" size="100%">Bella, Antonio</style></author><author><style face="normal" font="default" size="100%">Andrianou, Xanthi</style></author><author><style face="normal" font="default" size="100%">Del Manso, Martina</style></author><author><style face="normal" font="default" size="100%">Fabiani, Massimo</style></author><author><style face="normal" font="default" size="100%">Bellino, Stefania</style></author><author><style face="normal" font="default" size="100%">Boros, Stefano</style></author><author><style face="normal" font="default" size="100%">Mateo Urdiales, Alberto</style></author><author><style face="normal" font="default" size="100%">Vescio, Maria Fenicia</style></author><author><style face="normal" font="default" size="100%">Brusaferro, Silvio</style></author><author><style face="normal" font="default" size="100%">Rezza, Giovanni</style></author><author><style face="normal" font="default" size="100%">Pezzotti, Patrizio</style></author><author><style face="normal" font="default" size="100%">Ajelli, Marco</style></author><author><style face="normal" font="default" size="100%">Merler, Stefano</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">The relationship between human mobility and viral transmissibility during the COVID-19 epidemics in Italy</style></title><secondary-title><style face="normal" font="default" size="100%">arXiv preprint arXiv:2006.03141</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2020</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://arxiv.org/abs/2006.03141</style></url></web-urls></urls><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">We describe in this report our studies to understand the relationship between human mobility and the spreading of COVID-19, as an aid to manage the restart of the social and economic activities after the lockdown and monitor the epidemics in the coming weeks and months. We compare the evolution (from January to May 2020) of the daily mobility flows in Italy, measured by means of nation-wide mobile phone data, and the evolution of transmissibility, measured by the net reproduction number, i.e., the mean number of secondary infections generated by one primary infector in the presence of control interventions and human behavioural adaptations. We find a striking relationship between the negative variation of mobility flows and the net reproduction number, in all Italian regions, between March 11th and March 18th, when the country entered the lockdown. This observation allows us to quantify the time needed to &quot;switch off&quot; the country mobility (one week) and the time required to bring the net reproduction number below 1 (one week). A reasonably simple regression model provides evidence that the net reproduction number is correlated with a region's incoming, outgoing and internal mobility. We also find a strong relationship between the number of days above the epidemic threshold before the mobility flows reduce significantly as an effect of lockdowns, and the total number of confirmed SARS-CoV-2 infections per 100k inhabitants, thus indirectly showing the effectiveness of the lockdown and the other non-pharmaceutical interventions in the containment of the contagion. Our study demonstrates the value of &quot;big&quot; mobility data to the monitoring of key epidemic indicators to inform choices as the epidemics unfolds in the coming months.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Boncoraglio, Daniele</style></author><author><style face="normal" font="default" size="100%">Deri, Francesca</style></author><author><style face="normal" font="default" size="100%">Distefano, Francesco</style></author><author><style face="normal" font="default" size="100%">Daniele Fadda</style></author><author><style face="normal" font="default" size="100%">Filippi, Giorgio</style></author><author><style face="normal" font="default" size="100%">Forte, Giuseppe</style></author><author><style face="normal" font="default" size="100%">Licari, Federica</style></author><author><style face="normal" font="default" size="100%">Michela Natilli</style></author><author><style face="normal" font="default" size="100%">Dino Pedreschi</style></author><author><style face="normal" font="default" size="100%">S Rinzivillo</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">A Visual Analytics Platform to Measure Performance on University Entrance Tests (Discussion Paper)</style></title></titles><dates><year><style  face="normal" font="default" size="100%">2019</style></year></dates><language><style face="normal" font="default" size="100%">eng</style></language></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>47</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Lorenzo Gabrielli</style></author><author><style face="normal" font="default" size="100%">Daniele Fadda</style></author><author><style face="normal" font="default" size="100%">Giulio Rossetti</style></author><author><style face="normal" font="default" size="100%">Mirco Nanni</style></author><author><style face="normal" font="default" size="100%">Piccinini, Leonardo</style></author><author><style face="normal" font="default" size="100%">Dino Pedreschi</style></author><author><style face="normal" font="default" size="100%">Fosca Giannotti</style></author><author><style face="normal" font="default" size="100%">Patrizia Lattarulo</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Discovering Mobility Functional Areas: A Mobility Data Analysis Approach</style></title><secondary-title><style face="normal" font="default" size="100%">International Workshop on Complex Networks</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2018</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://link.springer.com/chapter/10.1007/978-3-319-73198-8_27</style></url></web-urls></urls><publisher><style face="normal" font="default" size="100%">Springer</style></publisher><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">How do we measure the borders of urban areas and therefore decide which are the functional units of the territory? Nowadays, we typically do that just looking at census data, while in this work we aim to identify functional areas for mobility in a completely data-driven way. Our solution makes use of human mobility data (vehicle trajectories) and consists in an agglomerative process which gradually groups together those municipalities that maximize internal vehicular traffic while minimizing external one. The approach is tested against a dataset of trips involving individuals of an Italian Region, obtaining a new territorial division which allows us to identify mobility attractors. Leveraging such partitioning and external knowledge, we show that our method outperforms the state-of-the-art algorithms. Indeed, the outcome of our approach is of great value to public administrations for creating synergies within the aggregations of the territories obtained.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>47</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Barbara Furletti</style></author><author><style face="normal" font="default" size="100%">Daniele Fadda</style></author><author><style face="normal" font="default" size="100%">Leonardo Piccini</style></author><author><style face="normal" font="default" size="100%">Mirco Nanni</style></author><author><style face="normal" font="default" size="100%">Patrizia Lattarulo</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Big Data and Public Administration: a case study for Tuscany Airports</style></title><secondary-title><style face="normal" font="default" size="100%">SEBD - Italian 	Symposium on  Advanced Database Systems </style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2016</style></year><pub-dates><date><style  face="normal" font="default" size="100%">06/2016</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://sebd2016.unisalento.it/grid/SEBD2016-proceedings.pdf</style></url></web-urls></urls><publisher><style face="normal" font="default" size="100%">Matematicamente.it</style></publisher><pub-location><style face="normal" font="default" size="100%">Ugento, Lecce (Italy)</style></pub-location><isbn><style face="normal" font="default" size="100%">9788896354889</style></isbn><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">In the last decade, the fast development of Information and Communication Technologies led to the wide diffusion of sensors able to track various aspects of human activity, as well as the storage and computational capabilities needed to record and analyze them. The so-called Big Data promise to improve the effectiveness of businesses, the quality of urban life, as well as many other fields, including the functioning of public administrations. Yet, translating the wealth of potential information hidden in Big Data to consumable intelligence seems to be still a difficult task, with a limited basis of success stories. This paper reports a project activity centered on a public administration  - IRPET, the Regional Institute for Economic Planning of Tuscany (Italy). The paper deals, among other topics, with human mobility and public transportation at a regional scale, summarizing the open questions posed by the Public Administration (PA), the envisioned role that Big Data might have in answering them, the actual challenges that emerged in trying to implement them, and finally the results we obtained, the limitations that emerged and the lessons learned.</style></abstract></record></records></xml>
