Volunteered Geographic Information (VGI) and social media data have become part of our everyday lives over the past few years. Whereas in the early beginnings of crowd-sourced data the data collection took place primarily on isolated VGI and social media platforms, contribution patterns are beginning to be more intertwined between different platforms. This means that crowd-sourcing applications begin to offer opportunities to share data between them during data collection and contribution, for example, by tweeting an Instagram image or by viewing a Mapillary image layer while editing OpenStreetMap data. Recent data contribution trends show also that geographic data are beginning to be linked across different VGI and social media platforms. As an example, users started to cross-link OSM point of interests (POIs) and street features (e.g. street lamps, sidewalk information) based on Mapillary photographs. This cross-linkage of data between different platforms brings new opportunities and challenges, including questions of data quality and the formation of user communities across platforms. It can also be observed that the number of VGI and social media platforms is continuously growing, providing new data sets to be analyzed.
All these changes in the VGI world bring new opportunities and challenges, including questions of data quality and the formation of user communities across platforms. This workshop provides an opportunity for interested researchers to share ideas and findings on cross-platform data contributions, innovative analysis approaches, current data fusion methods, real-world applications using cross-linked data, and novel crowd-sourcing and social media platforms.
This workshop provides an opportunity for interested researchers to share ideas and findings on cross-platform data contributions, innovative analysis approaches, current data fusion methods, real-world applications using cross-linked data, and novel crowd-sourcing and social media platforms. It allows participants also to discuss technical questions and innovations on data access. One portion in the workshop is dedicated to a collaborative session, where break-out groups will discuss some specific aspects of cross-linked VGI data.
The workshop offers two formats for paper submission:
The VGI-Analytics 2017 workshop will be organised and co-chaired by:
The VGI-Analytics 2017 workshop will discuss, but not be limited to, the following workshop topics and themes:
VGI-Analytics follows on from a very successful pre-AGILE conference workshop in Helsinki in June 2016 with 30 attendees registered called Link-VGI: LINKing and analyzing Volunteered Geographic Information (VGI) across different platforms. Please see the workshop web-page for LinkVGI 2016. LinkVGI is also published as a data descriptor from the hands-on session. Indeed the workshop organisers have been working together in this general research areas for several years now. In 2015 the RICH-VGI workshop (enRICHment of volunteered geographic information (VGI): Techniques, practices and current state of knowledge) was organised before AGILE 2015 in Lisbon, Portugal. An earlier pre-AGILE conference workshop ACTIVITY (Action and Interaction in Volunteered Geographic Information) was held in Leuven in May 2013 before AGILE 2013. A journal paper was produced after this workshop on the key outcomes of the workshop
The workshop will be a full day workshop. We intend to begin at 09:30 and finish at around 17:00. This will allow workshop delegates to either return back to their accommodation before the evening reception or to explore the university grounds or city of Wageningen. We aim to attract a high number of attendees.
The outline of the workshop is as follows below. The timings have been designed so that they work with the timetables of the other pre AGILE workshops for the purposes of coffee breaks and lunches. Papers will be available in the coming days. After the workshop presentations and other materials will also be openly accessible from this webpage.

Professor Robert Feick (University of Waterloo, Canada) and Dr. Colin Robertson (Wilfrid Laurier University, Canada)
Abstract: As research into VGI matures and expands to include multiple platforms, a greater variety of representations, and a broader range of applications, the development of a 'VGI Analytics' requires new conceptual models and frameworks to underly the development of algorithms and spatial tools. In the 10 years since Goodchild's 2007 paper, the line between VGI and GI proper has continued to blur. In this paper we revisit the underlying tenets of VGI in an attempt to build up a three-part model of VGI analytics, considering the people that produce VGI, the aggregate patterns they produce, and the ways that these patterns (mis)-represent larger populations. We consider how geographical expertise relates to spatial knowledge production and representation in VGI datasets, and in turn, the analysis of VGI with traditional geospatial tools. Case studies from citizen science and geosocial media data are used to illustrate problems and articulate potential solutionsKeynote Presentation Download

|14:30 - 15:30|| Collaborative Session - the idea here would be to break the workshop up into 4 - 5 small groups. Each group would be led by one of the organisers or an experienced academic/researcher. Then each group would try to tackle some of the current challenges in VGI-Analytics with the view of working towards the draft for a multi-author journal paper. At the end of the session each group will have gathered together a roughwork document of ideas, formulations, plans, etc to bring their paper forward after the workshop. Very often one of the negative aspects of workshops is that the potential energy for collaboration and future networking diminishes after the workshop is finished. A tangible and shared collaborative output like this could help build capacity for sustaining this collaboration. This is also an excellent opportunity for PhD students and other young researchers to work and collaborate with more experienced academics/researchers. |
Outputs from the Collaborative Sessions will be publicly available soon!
There were three breakout groups:
|15:30 - 16:00||COFFEE (This is in parallel with the other workshops)|
|16:00 - 16:30||Feedback and Discussion: Short feedback and summary from each group leader. Discussions from the floor|
|16:30 - 17:00||Closing: Workshop Closing - summary and overview of the day from the Workshop Chair. Plans for the future.|
The AGILE 2017 website will contain information and directions of how to travel to Wageningen University.
REGISTRATION for the VGI-Analytics 2017 will be handled directly with your registration for the AGILE 2017 conference. This webpage will not provide a facility to register for the workshop. There will be a small registration fee for this workshop which is collected by AGILE.
