Geofencing mechanisms allow for timely message delivery to the visitors of predefined target areas. However, conventional geofencing approaches poorly support mobile data collection scenarios in which experts need in situ assistance. In this paper, we propose crowd geofencing environments, in which a large number of crowdworkers generate geofences to ...

Learning Crowd Motion Dynamics with Crowds
Proceedings of the ACM on Computer Graphics and Interactive TechniquesReinforcement Learning (RL) has become a popular framework for learning desired behaviors for computational agents in graphics and games. In a multi-agent crowd, one major goal is for agents to avoid collisions while navigating in a dynamic environment.

Conceptions of Crowds and Crowding
1986In a volume that has as its topic theories of crowd mind and behavior, taken as one origin of social psychology, it appears consistent if not compelling to include theories of crowding. The linguistic relationship of “crowds” and “crowding” is most evident in the English language, in which “crowd” can be used as a noun or a verb. In the German language,

Proceedings of the VLDB Endowment, 2012
In this paper, we address the problem of selectivity estimation in a crowdsourced database. Specifically, we develop several techniques for using workers on a crowdsourcing platform like Amazon's Mechanical Turk to estimate the fraction of items in a dataset (e.g., a collection of photos) that satisfy some property or predicate (e.g., photos of trees).

Crowding out or crowding in? [PDF]
, 2005 Intergenerational support regains attention in course of population aging. This paper focuses on the relationship between private and public financial transfers to and from the elderly. Based on German data we find that the giving of private transfers is influenced by public transfers.

Research into the methods and techniques used in simulating crowds is now reaching maturity, but until now there is no book that focuses on this important topic. Prior approaches have been application-specific focusing on different aspects of collective behaviour and using different modelling techniques.

Anhydrobiosis, the exceptional adaptation of some organisms to enter a state approaching suspended animation after losing most cellular water, has fascinated scientists and non-scientists since Anthony van Leeuwenhoek described the phenomenon over 300 years ago.
