Online citizen science projects engage volunteers in collecting, analyzing, and curating scientific data. Existing projects have demonstrated the value of using volunteers to collect data, but few projects have reached the full collaborative potential of scientists and volunteers. Understanding the shared and unique motivations of these two groups can help(More)
The Encyclopedia of Life (EOL, http://eol.org) aims to provide unprecedented global access to a broad range of information about life on Earth. It currently contains 3.5 million distinct pages for taxa and provides content for 1.3 million of those pages. The content is primarily contributed by EOL content partners (providers) that have a more limited(More)
UNLABELLED The association of organisms to their environments is a key issue in exploring biodiversity patterns. This knowledge has traditionally been scattered, but textual descriptions of taxa and their habitats are now being consolidated in centralized resources. However, structured annotations are needed to facilitate large-scale analyses. Therefore, we(More)
Encyclopedia of Life (EOL) has developed TraitBank (http://eol.org/traitbank), a new repository for organism attribute (trait) data. TraitBank aggregates, manages and serves attribute data for organisms across the tree of life, including life history characteristics, habitats, distributions, ecological relationships and other data types. We describe how(More)
Citizen scientists are motivated by a variety of factors to contribute biodiversity data to collaborative projects, and these factors change over time. Initially, citizen scientists tend to be motivated by their own intrinsic interests. However, for them to continue to contribute, other factors are necessary to motivate them: feedback about their(More)
A key problem for crowd-sourcing systems is motivating contributions from participants and ensuring the quality of these contributions. Games have been suggested as a motivational approach to encourage contribution, but attracting participation through game play rather than scientific interest raises concerns about the quality of the data provided, which is(More)

This thesis systematizes the previously ad hoc speciication of targets and motion commands for visual deictic control of mobile robots, which enables control of mobile robots in the real world without requiring foreknowledge of the environment. Whereas ad hoc (or generic) visual targets may be scattered densely enough in the world to support deictically(More)
Citizen science projects increasingly incorporate the motivational affordances of games. However, the different user groups that gamified citizen science projects may attract are poorly understood. This project examines how two user groups, nature participants and gamer participants, experience Floracaching, a gamified mobile application for citizen(More)
—Social network visualization is useful for understanding the complex structure of collaborative efforts such as citizen science projects. It has been widely accepted by social network analysts for exploring and analyzing networks by visually showing their members, the relationships among them, and their behaviors and attributes. The strength of social(More)
