- The United Nations has declared 2010 the International Year of Biodiversity in recognition of the importance of biological diversity and the looming biodiversity crisis. Biological diversity provides ecosystem services critical to our planet. As much as 90% of the needs of the world’s poorest people depend directly on biodiversity for food, fuel, medicine, etc. [1]. Each species represents a volume in a “living library,” as each has evolved solutions to nature’s challenges, solutions that can benefit human society. For example, the genomics revolution and half of our synthetic drugs were made possible by understanding the characteristics of particular species [2]. Yet the rate of species loss is currently 100 to 1,000 times estimates of historical extinction rates, and these rates are increasing with climate change [2]. Recent assessments indicate that, for example, nearly 25% of mammals and one-third of amphibians are endangered or threatened [3].Scientists alone cannot end the biodiversity crisis. Progress in the conservation and sustainable use of biodiversity will depend on the interface of science with both policy and the public. This is not only because the public must appreciate and understand biodiversity in order to be motivated to conserve it. There are nearly 2 million known species and potentially millions more are still undocumented. Without help, professional biologists will be unable to describe many of these species before they disappear from the planet, especially those in biodiversity-rich but economically poorer countries [4].Public participation can address the biodiversity crisis in several areas. One area is assembling existing knowledge on the 1.9 million species known to science. Doing so can accelerate the pace of research and new species description by making freely available, searchable, and re-usable the information currently in libraries or in local databases inaccessible to most of the world’s scientists. Addressing this need is the primary mission of the Encyclopedia of Life (EOL, http://www.eol.org), an international project headquartered at the Smithsonian’s National Museum of Natural History. In addition to mash-ups of existing scientific databases, we are combining a crowd-sourcing approach with expert review to achieve a high-quality central clearinghouse for species information.
- Most citizen science . . .Is driven by scientistsIs analyzed by scientistsWorks best for charismatic speciesWorks best for simple observations or classificationRequires training – so sustained engagement desirableBioblitz is a 24-hour inventory of species in a particular location
- So, the approach of EOL is rather different than many other sites. EOL is a giant mashup that creates pages, that are then available for curators (mostly credentialed scientists) to assess and rate, or for anybody to provide comments or tags.
- Research QuestionsHow can we motivate users to continue to play when we are dealing with imperfect data that will sometimes provide two “correct” answers?What useful data for algorithm refinement can a game of tagging the least-similar image provide?How can data provided by novices users be employed to enhance the work of experts?ImplicationsImproving machine vision algorithms based on human performance.Minimizing the number of data sets that must be hand-verified by scientists and expertsProviding insight on what image factors provide for the best human identification of leavesProviding information on the extent that other game motivation techniques1 work for scientific identification games
