Urban Emotions and Realtime Planning Methods
The Urban Emotions approach combines methods and technologies from Volunteered Geographic
Information (VGI), Social Media, sensors and bio-statistical sensors to detect people’s perception for a new
perspective about urban environment. In short, it is a methodology for gaining and extracting contextual
information of emotion by using technologies from real-time human sensing systems and crowdsourcing
methods. “Real-time planning” describes a system in which planning disciplines get a toolset for a fast and
simple creation of visualization or simulation from municipal geodata in a consistent workflow. This
includes applications from Virtual Reality, Augmented Reality as well as the above mentioned combination
of real-time humane sensors and urban sensing systems. Due to the fact, that a real existing city never
corresponds with a laboratory situation, Virtual Reality can be one of the solutions to fill the gap for
detecting people’s perceptions concerning design, while filtering other unintended side effects. Insights and
results from Urban Emotions project, granted by German Research Foundation and Austrian Science Fond,
will be presented in this contribution. It is based on a German contribution, published earlier this year (Zeile
2017)
A Survey of Volunteered Open Geo-Knowledge Bases in the Semantic Web
Over the past decade, rapid advances in web technologies, coupled with
innovative models of spatial data collection and consumption, have generated a
robust growth in geo-referenced information, resulting in spatial information
overload. Increasing 'geographic intelligence' in traditional text-based
information retrieval has become a prominent approach to respond to this issue
and to fulfill users' spatial information needs. Numerous efforts in the
Semantic Geospatial Web, Volunteered Geographic Information (VGI), and the
Linking Open Data initiative have converged in a constellation of open
knowledge bases, freely available online. In this article, we survey these open
knowledge bases, focusing on their geospatial dimension. Particular attention
is devoted to the crucial issue of the quality of geo-knowledge bases, as well
as of crowdsourced data. A new knowledge base, the OpenStreetMap Semantic
Network, is outlined as our contribution to this area. Research directions in
information integration and Geographic Information Retrieval (GIR) are then
reviewed, with a critical discussion of their current limitations and future
prospects
