Joe Biden and Paul Ryan: Pre and Post Debate - Rohan Kulkarni

I would like to start by thanking Peter for inviting me to write this post on the Swarm Creativity blog. I have been in Peter’s COINs class for over a month now and I am thoroughly fascinated by what social network analysis can teach us.

For the COINs class’ midterm exam that involves gathering, analyzing and inferring from social media data, I was assigned the topic “Joe Biden against Paul Ryan”. It was a great topic for me since I was planning on doing some coolhunting on this topic after the Vice Presidential debate that evening. Conducting the analysis before the debate made the results even more interesting. I have used Condor’s Twitter Collector to collect Twitter feeds and Condor Web Collector’s Google Blog Search to collect website data. Here are the results, pre and post-debate.

Pre-Debate Analysis

Twitter

Following image shows the network of users talking about Paul Ryan and Joe Biden on Twitter. The blue dots are users talking about Joe Biden, the green are talking about Paul Ryan and the red are talking about both of them.

We can see that there are more people talking about Paul Ryan compared to those talking about Joe Biden. The following image shows that the betweenness centrality (or popularity) of Paul Ryan is much greater than that of Joe Biden.

Now let us see what people are actually talking about. Following image shows the terms widely used by users while talking about Joe Biden.

We can see that “Obama”, “Ryan” and “tonight” are quite important (or have higher “betweenness centralities” in SNA terminology). This is expected. However, the interesting terms that appear with a decent amount of betweenness centrality are “win” and “good”.

Now let us see what terms are being used by people talking about Paul Ryan.

Here also, we can see that “Joe”, “Biden” and “tonight” have high betweenness centralities. Interestingly, although the term “good” appears with high betweenness centrality, just as it did in Joe Biden’s network, the term “win” appears with a very low betweenness. Could this mean that although fewer people are talking about Joe Biden, they are talking more optimistically about him?

To go a little deeper, I used Condor’s Taxo tool to further analyze the twitter feeds. I extracted terms from 3 wikipedia categories
1) Emotion
2) Economics
3) Employment

Following image shows the terms from these taxonomies that appear in tweets about Joe Biden.

The interesting terms that appear with high frequency are “hope”, “shame” and “economics”.

The interesting terms that appear with high frequency are “economics”, “employment”, “hope”, “motivation” and “victory”.

Although Joe Biden’s taxonomy view doesn’t look too conclusive, Paul Ryan’s view seems very positive. Moreover his betweeness centrality is also high on twitter. Thus I can say that Paul Ryan is clearly more popular on twitter and positively so.

Google Blog Search

Now let us look at the google blog search results.

Following image shows the network of websites talking about Joe Biden and Paul Ryan. The blue dots are websites talking about Biden, the green are talking about Ryan and red are talking about both.

Following image shows the betweenness centralities for Paul Ryan and Joe Biden.

Clearly Joe Biden is more central in blogs. This is different from twitter, where Ryan was more central.

Now let us see which website is more influential. I have filtered “Joe Biden” and “Paul Ryan” from the websites. Following image shows the betweenness centralities of the top websites.

We can see that huffingtonpost.com is the most influential website in the blog search, followed by foxnewsinsider.com.

Now let us look at the sentiment analysis of the content on the websites. The dots above the zero represent positive sentiment and the ones below the zero represent negative sentiment.

Joe Biden’s sentiment view:

We see a lot of positive sentiment for Joe Biden.

Paul Ryan’s sentiment view:

Ryan’s sentiment view looks quite balanced and is not very skewed towards positive, unlike Biden’s, which is clearly positive.

Conclusions:

1) Twitter analysis shows Paul Ryan to be clearly more popular and positive
2) Blog analysis shows that Joe Biden is more popular and positive
3) Since twitter is more dynamic than blogs, I would conclude that Joe Biden has a historical positive sentiment going for him, but Ryan is the new and popular kid on the block.
4) We need to keep an eye on huffingtonpost.com and foxnewsinsider.com to see what they are saying about the 2 candidates. What they say is clearly very influential

Post-Debate Analysis

Twitter

The twitter feeds after the debate were collected every hour from the time the debate ended at about 10:30PM EDT till the next morning. This was done so as to be able to see the change in the betweenness centralities of the two candidates over the few hours after the debate.

The following image shows the network of users talking about Joe Biden and Paul Ryan after the debate.

The blue dots are users talking about Joe Biden, the green are users talking about Paul Ryan and the red dots are users talking about both the candidates. Unlike the pre-debate view, we can see a much larger fraction of people is talking about Joe Biden after the debate.

The following image shows the betweenness centralities of the 2 candidates.

Joe Biden is in fact more central post-debate than he was before the debate. This does not tell the complete story though. Let’s analyze the content of the tweets to figure out what people are actually saying about the 2 candidates.

The following image shows the terms that appeared frequently in tweets about Joe Biden.

In addition to the obvious “tonight”, “Obama” and “vice” we see the terms “rude” and “laughing” being used a lot. These terms do indicate a bit of negativity in the tweets about Biden. After the debate, Joe Biden was criticized quite a bit for his condescending and rude demeanor during the debate.

The following image shows the terms that appeared frequently in tweets about Paul Ryan.

There is nothing that really stands out that may be attributed to a positive or negative tone in the tweets about Paul Ryan.

Now let us look at how the betweenness centrality of the two candidates changed over the few hours after the debate. The blue line represents the betweenness centrality of Joe Biden and the green line represents the betweenness centrality of Paul Ryan over time.

We can see a surge in Joe Biden’s centrality for some time after the debate. However, Paul Ryan does catch up and finally surpass Joe Biden in centrality in due course of time. This indicates that more people did talk about Biden for some time after the debate, but went back to talking about Ryan soon. Moreover, the analysis of terms shows that quite a bit of the talk about Biden might have been negative.
