Facebook Meme Hunting with Data Analysis with R

Exploratory Data Analysis is an approach to data analysis for summarizing and visualizing the important characteristics of a data set. It can be used to get a quick, basic understanding of a data set.

We can explore and visualize interesting questions such as, “When do memes pop up in social networks?” Below, Facebook data scientist Lada Adamic explains how she uses EDA techniques to follow a meme’s Facebook presence over time.

As Lada explains, a meme is an idea that replicates itself. In a social network, you may see a meme suggesting that you repost it to all of your friends.

In this example, Lada is interested in the Moneybags meme, which has popped up on Facebook regularly over the years, and is specifically adapted to Facebook by suggesting that readers copy and paste to share with their friends.

Lada wants to know how this Facebook-specific meme keeps recurring over time. A quick glance at a plot of the meme’s occurrence over time shows that it seems to disappear in between spikes of activity.


Check out the full lesson here! Lada tries some EDA techniques to see what is happening! She tries looking at meme occurrences over time using a log scale instead of a linear scale, and we are now able to see that the meme does not disappear entirely between spikes, and instead persists in low numbers over time before being replicated in variations and becoming popular once again.
