Proceedings of the ACM First International Workshop on Understanding the City with Urban Informatics

The publication date is one day earlier then the EST date to provide the proceedings to attendees in Australian on the first day of the conference It is our great pleasure to welcome you to the 1st Workshop on Understanding the City with Urban Informatics -- UCUI'15. This workshop aims to provide a multidisciplinary forum which brings together researchers in Big Data (BD), Information Retrieval (IR), Data Mining, and Urban Studies, to explore novel solutions to the numerous theoretical, practical and ethical challenges arising in this context. These include difficulties in collecting city data, creating data management infrastructures, and providing new effective and efficient information access techniques, to as many users as possible in the context of a smart city. Our call has attracted nine papers. The program committee, which is formed of 14 experienced researchers, accepted six papers for presentation in the workshop, i.e. three technical papers, and three position papers. These papers represent the ideas and opinions of the authors who are trying to stimulate debate. In addition, two keynotes helped us frame the problem, and create a common understanding of the challenges. Finally, as part of the workshop, we introduced our newly published datasets relating to the iMCD project of the University of Glasgow's Urban Big Data Centre and participants to our Urban Informatics Data Challenge presented their works.
