Big data sources do not mean the end of survey research.
Table 2.3: Examples of natural experiments using big data sources.
In particular, I will focus on big data sources created by companies and governments.
Then, in Section 2.3, I describe ten common characteristics of big data sources.
In fact, people who have worked with big data sources know that they are frequently dirty.
Then, in Section 2.3, I describe ten common characteristics of big data sources.
In fact, people who have worked with big data sources know that they are frequently dirty.
Finally, I will describe two strategies for combining survey data and big data sources.
Figure 3.12: Two ways to combine big data sources and survey data. .
To conclude, many big data sources are not representative samples from some well-defined population.
The company has plans to incorporate big data sources, such as MongoDB.
Big data sources, like Hadoop and NoSQL, need to integrate with existing BI and operational systems.
First, increasingly corporate big data sources come from digital devices in the physical world.
Then, I will illustrate three research strategies that can be used to successfully learn from big data sources.
The big data sources of today, and likely tomorrow, tend to have 10 characteristics.
One of the great advantages of many big data sources is that they collect data over time.
Understanding these 10 general characteristics is a helpful first step toward learning from big data sources.
Even though, from the perspective of researchers, big data sources are“found,” they don't just fall from the sky.
Many other big data sources also have information that is sensitive, which is part of the reason why they are often inaccessible.
As the work of Burke and Kraut illustrates, big data sources will not eliminate the need to ask people questions.
Thus, when big data sources appear to reproduce predictions of social theory, we must be sure that the theory itself was not baked into how the system worked.
As the work of Burke and Kraut illustrates, big data sources will not eliminate the need to ask people questions.
Most social scientists are already familiar with the process of cleaning large-scale social survey data, but cleaning big data sources seems to be more difficult.
Another way in which researchers can use big data sources in survey research is as a sampling frame for people with specific characteristics.
These sources of change are sometimes interesting research questions, but these changes complicate the ability of big data sources to track long-term changes over time.
In conclusion, big data sources, such as government and business administrative records, are generally not created for the purpose of social research.
As you will see, some of the examples in this book involve clever repurposing of big data sources that were originally created by companies and governments.
To conclude, many big data sources are drifting because of changes in who is using them, in how they are being used, and in how the systems work.
Three areas where I expect to see exciting opportunities are(1) non-probability sampling(section 3.4),(2) computer-administrated interviews(section 3.5), and(3)linking surveys and big data sources(section 3.6).
But, as was described in chapter 2, big data sources may not be accurate, they may not be collected on a sample of interest, and they may not be accessible to researchers.
