Résumé
City-Zen is an interactive temporal knowledge-browsing platform that aims to valorise cultural heritages. While many organizations propose relevant data sets, they are hardly accessed, analysed and reused because of the formats inconsistency and the inappropriate information browsing and visualization. The goal of the project is to valorise the existing cultural heritage through a citizen centric design platform. The use case of this project involves a user willing to discover the history of a region and to embark in a cultural journey in the past. This project addresses a novel approach of data analysis of both assessment methods of data quality and spatio-temporal information. The proposed paper will describe the approach, its model and its implementation tests in the context of the State of Wallis.
