Analysis of Twitter Networks to Aid Open Source Intelligence Capabilities: A Multilayer Network Approach
Abstract
Open Source Intelligence using social media is a practice which gives military intelligence analysts a window into the thoughts and minds of an online population. Using Social Network Analysis, user interactions on Twitter will be modeled as a weighted and directed network. Topic modeling through Latent Dirichlet Allocation uncovers the topics of discussion in Tweets and is then integrated into a multi-layer network which allows users to be connected to the conversations with which they have participated. Influential users in this network as well as highly connected groups of individuals are then discovered to paint a picture for intelligence analysts of the online landscape with which they are dealing. The results of this research demonstrate that the inclusion of topics in the social network allows for more robust xC;findings in influential users when analysts collect Tweets from a variety of discussions through the use of more general search queries. PageRank was identified as the best performing influence ranking method for this problem context and two potential community identification methods were analyzed.
