  • Putin’s 2014 Address to Federal Assembly Text Network Analysis

    putin-address-federal-assembly-2014-text-network-analysis

    Every year in December Vladimir Putin addresses the Russian Federal Assembly. His address is considered to be a good indicator of the current political mood in the country. Putin’s 2014 speech is especially interesting, because it concerns not only Russia but the whole world. We at Nodus Labs together with Way to Russai analyzed Vladimir Putin’s address made on the 4th of December 2014 using text network analysis and below we present a report on what we discovered. We also made a comparison of the 2014 speech to the 6 speeches before from the years 2008-2013 to see how presidential rhetorics evolved over time.

  • Twitter xRay Using Text Network Analysis

    Text network analysis can be a very useful tool to make sense of Twitter’s ever-expanding newsfeed. It can be used to visualize a user’s feed of tweets or visualize one’s own newsfeed as a network to be able to see what the tweets are about and how they connect. Text network analysis allows to see not only the main terms, but also how they connect, providing the context to the most relevant keywords found on Twitter.

  • Textexture: The Non-Linear Reading Machine

    interface-web

    When we read a text, we normally follow it in quite a linear fashion: from left to right, from top to bottom. Even when we skim articles quickly online, the trajectory is still the same. However, this is not the most efficient method of reading: in the age of hypertext we tend to create our own narratives using the bits and pieces from different sources. This is an easy task with short Tweets or Facebook posts, but it becomes much more difficult when we’re dealing with newspaper articles, books, scientific papers. The amount of information we’re exposed to increases from day to day, so there’s a challenge of finding the new tools, which would enable us to deal with this overload.

    As a response to this challenge we at Nodus Labs developed a new free online software tool Textexture.Com, which visualizes any text as a network and enables the user to use this interactive visualization to read through the text in a non-linear fashion. Using the network one can see the most relevant topics inside the text organized as distinctively colored clusters of nodes, their relationship to one another, and the most influential words inside the text, responsible for topic shifts. This way the user can navigate right into the topic of the text that is the most relevant to them and use the bigger (more influential) nodes to shift into another subject.
