ChiLab4It system in the QA4FAQ competition

2017

ChiLab4It is the Question Answering system (QA) for Frequently Asked Questions (FAQ) developed by the Computer-Human Interaction Laboratory (ChiLab) at the University of Palermo for participating to the QA4FAQ task at EVALITA 2016 competition. The system is the versioning of the QuASIt framework developed by the same authors, which has been customized to address the particular task. This technical report describes the strategies that have been imported from QuASIt for implementing ChiLab4It, the actual system implementation, and the comparative evaluations with the results of the other participant tools, as provided by the organizers of the task. ChiLab4It was the only system whose score re…

Hospitalizations of patients in Burgundy and in nine other french regions, spatial analysis of interregional flows from french hospital claims data

2015

Introduction / presentation of the context : The creation of ARS (Regional Healthcare Agencies) was accompanied by the regionalized organization of healthcare. Even though the administrative procedures for dividing the country into areas for healthcare coverage are well known, we propose a geographic analysis of the reasons why patients attend one hospital rather than another, which seem to escape the logic used by the authorities.Methods employed and sources of data : Using the PMSI-MCO, we studied the flow of patients living in one region to hospitals in other regions according to ten reasons for visiting hospitals. The analysis was completed by a cartographic analysis, which related the …

Ab initio study of tungsten trioxide WO3 in volume and surface area

2012

The structure and stability of different crystallographic phases of tungstentrioxide and the effect of potassium doping have been studied using ab initiocalcuations, both in the bulk and at the surface. The study was motivatedby experimental works on the growth of WO3 nanorods on a mica substrate.The nanorods adopt a hexagonal phase, which is metastable in bulk WO3.The first part of the manuscript reports the study of bulk WO3. For thehexagonal and monoclinique phase, the atomic structure is deterimined andcompared with different models that have been proposed in the experimentalliterature. The relative stability of the two phases is calculated as a functionof potassium doping. From this an…
