As of May 2015, Twitter boasts 302 million active users who are collectively producing 500 million Tweets per day. This is another measure that can be relevant to evaluating a node’s presumed degree of influence on its neighboring nodes. Based on this algorithm, the analysis yields results that are surprisingly similar to the actual election results, especially when one considers the general simplicity of our approach. Although the order of the trend topics could potentially have some significance to the analysis, for purposes of simplification of the proof-of-concept, I chose to ignore the ordering of the topics in the trend topic list. A graphical representation of one person’s network neighborhood on Facebook. These entities are often people, but may also be social groups, political organizations, financial networks, residents of a community, citizens of a country, and so on. Network analysis may play a considerable role in the new setup. And these numbers are continually growing. Social networks, in one form or another, have existed since people first began to interact. To create a network using the Twitter Trend Topics, I defined the following rules: For example, on October 26th, the cities of Fortaleza and Campinas had 11 trend topics in common, so the network for that day includes an edge between Fortaleza and Campinas with a weight of 11: In addition, to aid the process of weighting the relationships between the cities, I also considered topics that were not related to the election itself (the premise being that cities that share other common priorities and interests may be more inclined to share the same political leanings). The approach is applied to social network analysis … Betweenness centrality, for example, considers a node highly important if it forms bridges between many other nodes. Data science companies are finding Twitter trend topics increasingly useful as a valuable proxy for measuring public opinion. Each edge is weighted according to the number of trend topics in common between those two cities (i.e., the more trend topics two cities have in common, the heavier the weight that is attributed to the link between them). Some common network analysis applications include data aggregation and mining, network propagation modeling, network modeling and sampling, user attribute and behavior analysis, community … The analysis in this article relates specifically to the October 26th runoff election. This article describes the techniques I employed for a proof-of-concept that effectively analyzed Twitter Trend Topics to predict, as a sample test case, regional voting patterns in the 2014 Brazilian presidential election.
