======================================================= 1st Workshop on Understanding the City with Urban Informatics (UCUI 2015) in conjunction with CIKM 2015 Call for participation in Urban Informatics Data Challenge https://sites.google.com/site/ucui2015/ 23 October 2015, Melbourne, Australia ======================================================= IMPORTANT DATES Data challenge participation papers due: 28 September 2015 Notification of acceptance: 5 October 2015 Camera-ready date: 12 October 2015 Workshop date: 23rd October 2015 OVERVIEW As part of the workshop, we are providing access to newly published datasets relating to the iMCD project of the University of Glasgow's Urban Big Data Centre. This represents a unique opportunity to facilitate the comparison of approaches across a number of heterogeneous datasets, which were simultaneously collected over a fixed period of time, from various resources, including the Internet-based visual (Flickr) and textual (Twitter and News) media collections as well as environmental data about Glasgow. Authors may submit papers that use either one or many of these datasets, potentially supplemented by their own datasets. DESCRIBE THE CHALLENGE: Using the provided datasets, we are setting up a challenge to do two tasks: (I) Post-hoc Event Detection and (II) Open Task. The Post-hoc Event Detection task is to predict the events that are occurring in Glasgow city within the first two weeks of June 2015. Participants should consider the first week of June as a training data and the second week as a testing data for this task. For the Open Task, participants are free to perform any task desired with the data, provided that they cite the workshop. The authors can also report what they have done in a UCUI data challenge paper. The workshop organisers will choose the best papers for presentation during the workshop. DATASETS FOR THE CHALLENGE: The dataset collected for the UCUI’15 Urban Informatics data challenge can be downloaded from https://www.dropbox.com/s/90iijatfr0jw1ch/UCUI_DataChallenge_Data.tar.bz2?dl=0. This dataset consists of data collected from four data sources namely (1) Social Media, (2) News, (3) Environmental Data, and (4) Flickr as well as a Readme.txt file with all required information about the data. SUBMISSION GUIDELINES We welcome data challenge papers as follows: Data challenge papers should not exceed 2 pages (including references and figures) and be formatted in the standard ACM conference format, with a two-column layout and must be submitted electronically in printable PDF format through the Easy Chair submission page: https://easychair.org/conferences/?conf=ucui2015. All submitted papers must be original and previously unpublished. The participation papers will not be peer-reviewed. The workshop organisers will examine the quality of the submissions. The participation papers will be published on the workshop website and the authors of accepted papers will be invited to present their papers at the workshop. The deadline for data challenge papers is September 28.
