In the human computation projects that I have discussed in the chapter, participants were aware of what was happening.
Finally, the examples in this section show that human computation can have a democratizing impact on science.
Now I can also highlight twoimportant differences between open call projects and human computation projects.
This comparison shows that, as with Galaxy Zoo, human computation projects can produce high-quality results.
In the human computation problems described in the previous section, the researchers knew how to solve the problems given sufficient time.
This comparison shows that, as with Galaxy Zoo, human computation projects can produce high-quality results.
Human computation projects take a big problem, break it into simple pieces, send them to many workers, and then aggregate the results.
If this approach does not scale well,the researcher can move to a human computation project with many participants.
Computer-assisted human computation systems also use machine learning in order to amplify the human effort.
In order to further build your intuition,table 5.1 provides additional examples of how human computation has been used in social research.
In addition to creating human computation and open call projects, researchers can also create distributed data collection projects.
According to the definition proposed in Ahn(2005) Foldit- which I described in the section on open calls-could be considered a human computation project.
Second, by some definitions of human computation(e.g., Ahn(2005)),Foldit should be considered a human computation project.
For researchers planning to use a microtask labor market(e.g.,Amazon Mechanical Turk) for a human computation project, Chandler, Paolacci, and Mueller(2013) and J.
A classic example of a human computation project is Galaxy Zoo, where a hundred thousand volunteers helped astronomers classify a million galaxies.
The term“split-apply-combine” was used by Wickham(2011) to describe a strategy for statistical computing,but it perfectly captures the process of many human computation projects.
In other words, human computation enabled them to generate coding of political texts that agreed with expert evaluations and was reproducible.
Researchers interested in creating what I have called computer-assisted human computation systems(e.g., systems that use human labels to train a machine learning model) might be interested in Shamir et al.
In human computation projects, such as Galaxy Zoo, where researchers have explicit control of the tasks, the focus of attention is easiest to maintain.

The term“human computation” comes out of work done by computer scientists, and understanding the context behind this research will improve your ability to pick out problems that might be suitable for it.
In the end, the quality of the output of human computation projects rests on the quality of the inputs that the human participants provide: garbage in, garbage out.
In human computation projects, researchers combine the efforts of many people working on simple microtasks in order to solve problems that are impossibly big for one person.
First, one way that I distinguish between human computation and open call projects is whether the output is an average of all the solutions(human computation) or the best solution(open call).

Galaxy Zoo, and other human computation projects, typically use a split-apply-combine strategy(Wickham 2011), and once you understand this strategy you will be able to use it to solve lots of problems.
For example, in the human computation project described below, the same recipe will be followed, but the apply and combine steps will be quite different.
Further, because the human computation was quick and cheap, it was easy for them to customize their data collection to their specific research question about immigration.
In social research, human computation projects are most likely to be used in situations where researchers want to classify, code, or label images, video, or texts.
