Abstract

Tags for citizens project aims to empower the citizens' experience within the Turin municipality website (http://www.comune.torino.it) integrating a standard top-down taxonomy with a bottom-up classification by tags. The top-down taxonomy has been conceived following the UK Integrated Public Sector Vocabulary (IPSV 2006 - an ISO 2788 fully compliant classification scheme) and empirically refined by usability tests with users and by log files monitoring. The bottom-up classification works as a social tagging system. The latter it is not simply added to the former, but completely integrated to it, in order to obtain a coherent system.
