How to leverage new'big data' sources, such as genomics.
Then, in Section 2.3, I describe ten common characteristics of big data sources.
Most big data sources are not accessible to researchers.
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.
In the next section,I will describe ten common characteristics of big data sources.
As these examples illustrate, corporate big data sources are about more than just online behavior.
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.
First, increasingly corporate big data sources come from digital devices in the physical world.
In fact, I think that many of the challenges and opportunities created by big data sources follow from just one“W”:.
When thinking about big data sources, many researchers immediately focus on online data created and collected by companies, such as search engine logs and social media posts.
Even though, from the perspective of researchers, big data sources are“found,” they don't just fall from the sky.
First, in section 2.2, I describe big data sources in more detail and clarify a fundamental difference between them and the data that have typically been used for social research in the past.
Based on the ideas in this chapter,I think that there are three main ways that big data sources will be most valuable for social research.
First, in section 2.2, I describe big data sources in more detail and clarify a fundamental difference between them and the data that have typically been used for social research in the past.
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.
The practical and fundamental limitations of big data sources, and how they can be overcome with surveys, are illustrated by Moira Burke and Robert Kraut's(2014) research on how the strength of friendships was impacted by interaction on Facebook.
Talend studio is an easy-to-usegraphical development environment that allows for interaction with big data sources and targets without the need to learn and write complicated code.
I think the idea of repurposing is fundamental to learning from big data sources, and so, before talking more specifically about the properties of big data sources(section 2.3) and how these can be used in research(section 2.4), I would like to offer two pieces of general advice about repurposing.
That is, researchers need to understand the characteristics of big data sources- both good and bad- and then figure out how to learn from them.
I think the ultimate source of this difficulty is that many of these big data sources were never intended to be used for research, and so they are not collected, stored, and documented in a way that facilitates data cleaning.
This breakneck pace could see genomics in 2025 surpass by10x the amount of data generated by other big data sources such as astronomy, Twitter and YouTube- hitting the double-digit exabyte range.
As the work of Burke and Kraut illustrates, big data sources will not eliminate the need to ask people questions.
Machine Learning/ Deep Learning(ML/DL)algorithms proved to be helpful in processing big data sources that accumulate the network performance metrics sampled at high frequency, and with breakdown to individual services(flows) rather than aggregated per RAN cell.
Too often, however, researchers seem to treat the size of big data source as an end-“look how much data I can crunch”- rather than a means to some more important scientific objective.
It's already becoming the biggest data source in the world.
