Kiran Kumar Bandeli successfully defended his doctoral dissertation “A Framework Toward Computational Narrative Analysis on Blogs/Social Media” Monday, November 25, 2019.  In attendance were committee members Dr. Nitin Agarwal (chair), Dr. Elizabeth Pierce, Dr. John Talburt, and Dr. Ningning Wu as well as members of COSMOS.  During his time at COSMOS, Kiran quickly familiarize himself with blogs.  “Blogs in particular act as virtual spaces where narratives are framed. It is therefore important to study and understand the way information is said by the actors on social media platforms,” Kiran explained. Narratives are organized, long-lasting themes and ideas that persist in discourses. It is challenging toRead More →

Doctoral student Zachary Stine’s article “Characterizing the Language‑Production Dynamics of Social Media Users” was accepted for publication by Springer’s Social Network Analysis and Mining (SNAM) on September 28, 2019. The article, co-authored by Dr. Nitin Agarwal, was published online on October 3. Abstract:  In this paper, we propose a characterization of social media users based on language usage over time in order to make more rigorous the notions of organic and inorganic online behavior. This characterization describes the extent to which a user’s word usage within a particular time period subverts expectations based on preceding time periods. To do this, we adapt the use ofRead More →

On Friday, September 27th, doctoral candidate Adewale Obadimu successfully defended his PhD proposal, “Assessing the Role of Social Media Platforms in the Propagation of Toxicity.”  Obadimu defined toxicity as any “rude, disrespectful, or unreasonable comment that is likely to make people leave a discussion.” He argued that users who exhibit this toxic behavior will become worse over time, and that anyone could potentially display this type of behavior online.  His research aims to answer specific questions: Are toxic users clustered/segregated in an online discussion? Is toxicity contagious? Can we leverage toxic signals for predictions? To begin his research, Obadimu focused on a sample of userRead More →

On Friday, September 20th, doctoral candidate Kiran Kumar Bandeli presented his ongoing research on computational narrative analysis on blogs and social media at the EIT Colloquium.  “Blogs in particular act as virtual spaces where narratives are framed. It is therefore important to study and understand the way information is said by the actors on social media platforms,” Bandeli explained. Narratives are organized, long-lasting themes and ideas that persist in discourses. It is challenging to extract narratives from social media, and even more so to interpret them. However, developing a more effective way to study these narratives carries great implications, paving the way for strategic communicationRead More →

On Monday, September 23, participants of the Department of State’s International Visitor Leadership Program made a stop at UA Little Rock. Individuals from seven different countries spent the morning speaking with members of the COSMOS team to learn about the broad range of research taking place, particularly regarding social cyber security and misinformation on social media. The countries represented include Bulgaria, Czech Republic, Estonia, Georgia, Montenegro, Romania, and Tajikistan. Delegates learned about tools COSMOS Cosmographers have developed in order to study disinformation on social media platforms. Blogtrackers is a tool designed by Dr. Nitin Agarwal in 2009 to to track and analyze blogs and gainRead More →

Ph.D. student Kiran Kumar Bandeli has been invited to speak about “Computational Narrative Analysis on Blogs/Social Media.” The colloquium will be held in the Donaghey College of Engineering and Information Technology (EIT) Building, Room 217 at 3:00pm CST.

The annual conference invited communication professionals from within NATO as well as academia and industry to discuss tools and strategies for Information Environment Assessment (IEA), the theme of this year’s conference.   Mrs. Galeano was invited to the NICC to demonstrate technologies developed by COSMOS during the workshop sessions held on Thursday, September September 20.  As one of only 51 presenters from NATO, industry and academia from all NATO member states, she presented COSMOS’Read More →

Please allow me to introduce myself to you; I am Rita Chowdhury a full-time, second-year MBA student at the UA Little Rock College of Business and a Graduate Research Assistant at COSMOS – a research team in the Department of Information Science. Apart from that I am currently a student member of the Joe T. Ford Investment Fund at the College of Business. Many a time the introduction makes way for numerous questions. Much like why am I in an Information Science research team? What might I be doing? How did I make it to the team? Do I have an engineering undergraduate degree? IfRead More →
