CySoc 2024

The International Workshop on Cyber Social Threats (CySoc), co-located with the AAAI International Conference on Web and Social Media (ICWSM 2024), looks at discovering and mitigating cyber social threats. In other words, this conference is concerned with how social media platforms can negatively and detrimentally affect social contexts, that is, social threats enabled by technology. The range of topics that the conference features are thus quite extensive. This ranges from the complex landscape of generative artificial intelligence, both in its use and misuse, to the rise of online extremism and other pervasive social issues like harassment, cyberbullying, and hate speech. It also features research on how the digital realm can involve gender-based violence, human trafficking, and drug trafficking. More generally, the conference invites studies that look at how social media can negatively affect our society (such as promoting misinformation and disinformation) as well as our mental health and ethical concerns.

From 3 to 6 June 2024, the 5th CySoc conference was held in Buffalo, New York. There Oluwaseyi Adeliyi, Ishmam Solaiman, Shadi Shajari, Ugochukwu Onyepunuka, and Dr. Nitin Agarwal presented their research titled “Detecting and Characterizing Inorganic User Engagement on YouTube,” and Emmanuel Addai, Niloofar Yousefi, and Dr. Nitin Agarwal presented their research titled “SEIQR: An Epidemiological Model to Contain the Spread of Toxicity using Memory-Index.” The former study looked at the cyber threat of inorganic accounts and bots, while the latter study looked at the cyber threat of toxicity.

The first study focused on identifying and characterizing YouTube accounts that use automated means to boost their use engagement and to potentially amplify misinformation. To achieve this, their methodology combined four main approaches: rolling window correlation, anomaly detection, rule-based classification, and Principal Component Analysis (PCA)/clustering. Rolling window correlation looks at how different engagement statistics, such as views and subscribers, change in correlation over time. Anomaly detection and rule-based classification then used, respectively, models and algorithms to assess abnormal or inorganic engagement, based on changes in the rolling window correlation. PCA then reduced the data while minimizing information loss—PCA enabled the reduction in complexity of the data. Their predictions were then confirmed by the high number of suspended channels from the group of channels identified as having inorganic activity.

The second study focused on evaluating a new epidemiological model for toxicity that accounts for quarantined users: the SEIQR (Susceptible-Exposed-Infected-Quarantined-Recovered) model.  Unlike traditional epidemiological models, this model incorporated memory effects, improving accuracy in predicting behavior by considering an individual’s past actions. The study evaluated several parameters, including the reproduction number (the number expressing the average number of cases transmitted from a single infected individual), the toxic post-free equilibrium point (an equilibrium that indicates toxicity or a disease has ceased spreading), and stability solutions. Using the model and adjusting the parameters, the authors determine the individuals to quarantine to reduce toxicity spread, carefully choosing the smallest number of individuals by determining the most impactful users. Their findings suggested that the memory index and quarantine rate can be effective measures for controlling toxicity, achieving a low error rate of 0.003 while minimizing user removal from the network.​

Dr Agarwal said, “Together these and other efforts at COSMOS are developing ways to mitigate socio-cognitive attacks and strengthen community resiliency. We are grateful to the U.S. Army DEVCOM Army Research Laboratory, Air Force Research Laboratory, Office of Naval Research, National Science Foundation (NSF), Maulden-Entergy Endowment at the University of Arkansas at Little Rock, and Arkansas Research Alliance for supporting the research.”

Staff Senate Award

The Staff Senate gives awards to recent graduates and staff members or teachers, at the annual Staff Awards Ceremony, held this year on April 19th 2024. This year, Cosmographer Ahmed Al-Taweel received one such award at the 2024 Ceremony—the Academic Excellence Award.

Ahmed has been part of COSMOS and UA Little Rock’s staff since January 2023, starting out as a graduate assistant at COSMOS and now working as a postdoctoral researcher after having received his PhD in May 2023.

BeyondFacts @The Web Conference 2024

The International Workshop on Computational Methods for Online Discourse Analysis (BeyondFacts) co-located with the 31st ACM International Web Conference aims to further research that uses computational methods to discover data on the Internet, or, in other words, content and sources spreading information on the Internet; this conference features strong interdisciplinary research that can assist these computational methods, such as communication studies and computational linguistics. They aim to strengthen relationships between disparate scientific disciplines, so that web mining can be further improved by interdisciplinary research. The range of topics that the conference features are:

  • Discourse analysis
  • Social we mining
  • Argumentation mining
  • Computational fact-checking
  • Mis-and dis-information spread
  • Bias and controversy detection and analysis
  • Stance / viewpoint detection and representation
  • Opinion mining
  • Rumour, propaganda and hate-speech detection
  • Computational journalism

From 13 to 17 May, 2024, the 4th BeyondFacts conference will be held in Singapore. There Mayor Inna Gurung, Md Monoraual Islam Bhuiyan, Ahmed Al-Taweel, and Dr. Nitin Agarwal will present their research titled “Decoding YouTube’s Recommendation System: A Comparative Study of Metadata and GPT-4 Extracted Narratives.” This research uses AI and natural language processing (NLP)  to examine videos on YouTube about the South China Sea dispute. 

“The study reveals several interesting facets. First, it shows narratives are more meaningful to analyze than just the video titles or descriptions. Second, the study sheds light on the inherent bias in the YouTube recommendation algorithm that is more visible when narratives are analyzed as compared to just the video title and description. These findings are helpful for developing efforts to de-bias the algorithms and assist in understanding strategic manipulation of algorithmic bias,” Dr. Agarwal said.

Notably, they found that recommended videos shifted from neutral to positive sentiments, from negative to positive emotions, and from more to less toxicity. These findings—beyond establishing the nature of the videos themselves—seem to indicate that, the deeper the user’s engagement, the more their toxicity and sentimental and emotional expressions are affected. They also illustrate that evaluating drift solely upon metadata like video titles can lead to incomplete or inaccurate characterizations of the video content, as Mayor Inna explains, saying, “We discovered that relying solely on titles and metadata may not always provide an accurate representation of the content within a video.” Video titles showed little change in sentiment, emotion, and toxicity, while video transcripts showed dramatic changes and trends in sentiment, emotion, and toxicity. “Our findings emphasize the importance of delving deeper into the actual video content rather than solely relying on surface-level metadata,” says Mayor Inna.

“Narrative analysis plays a crucial role in computationally extracting narratives,” explains Mayor Inna. “With the utilization of large language models like GPT, we’ve unlocked the ability to extract narratives from a wide range of content, and an excellent example of the need for such an advanced approach is the South China dispute, a pressing and continually evolving issue.”

Research Spotlight

In this month’s research spotlight, COSMOS highlights two recent studies that both model and investigate the global refugee crisis. The paper by Dr. Esther Mead, Dr. Maryam Maleki, Dr. Mohammad Arani, and Dr. Nitin Agarwal titled “Proposing Location-based Predictive Features for Modeling Refugee Counts,” used features to identify locations of refugee crisis. Similarly, the paper by Kazi Tanvir Islam, Dr. Esther Mead, and Dr. Nitin Agarwal titled “Impact of Data Imputation on the Performance of Global Refugee Modeling Dataset” used data imputation assisted by machine learning AI to make predictions of refugee populations when there were missing predictive values. 

These research studies explore the various ways trends in refugee populations can be predicted. In particular, they both look at whether these populations can be predicted through sociocultural, socioeconomic, and economic features.

The first study found some location-based features that stood out in prediction. The authors found that the global peace index, access to electricity, access to water, media censorship, and healthcare stood out as features for predicting refugee populations. Additionally, they found their model predicted best for European countries, most notably those that had data for features of justice and homicide rates. The model also showed features that were especially predictive for certain locations, such as corruption features for African and Asian countries and population features for the Americas.

The second study then looked at how models can predict when there is an absence of data, namely models that account for missing values by using data imputation. They compared four machine learning methods with the three traditional data imputation techniques of mean, median, and mode. After taking a real-world dataset and removing values, each of the seven methods was applied to the dataset and then compared to the real-world dataset with no missing values. What they found was that stochastic regression—a machine learning method that replaces values by following a linear regression, or trends—achieved the highest accuracy. 

“Together, these studies show how computational methods can be applied to predict real-world refugee populations. Policy makers, human rights organizations, and general researchers can use these models to predict population fluctuations related to refugee populations”, said Dr. Agarwal.

Cosmographer Corner: Dr. Samer Al-Khateeb, Professor, Creighton University

COSMOS, in this edition of Cosmographer Corner, highlights the work of a former University of Arkansas – Little Rock graduate and Cosmographer Dr. Samer Al-Khateeb. Dr. Al-Khateeb—who is now a tenured associate professor at Creighton University, in Omaha, Nebraska—started his graduate education as a COSMOS researcher during its inception. He received his BS in Computer Science, MS in Applied Science, and Ph.D in Computer and Information Sciences from UA Little Rock in 2013, 2015, and 2018, respectively. During that time, Dr. Al-Khateeb worked at COSMOS as a graduate assistant, and after receiving his Ph.D, he worked at COSMOS as a postdoctoral fellow. We interviewed Dr. Al-Khateeb on where his career is now and what his work at COSMOS entailed, with his responses below.

How long were you at COSMOS? How did you come across COSMOS originally, and what drew you to the team?

I finished my undergraduate degree in Computer Science at University of Arkansas at Little Rock in Spring 2013. I took Dr. Agarwal’s Social Computing class during my first semester as a graduate student. He showed us his work on the Saudi Women’s Right to Drive campaign, and I loved the project. So, I reached out to him when I was looking for a research advisor for my Master’s degree, and he shared a set of articles and his research proposal on mob behavior. He was planning to submit it to the U.S. Army Research Office at that time. I loved the project idea, and I decided to work on it.

For your work on mob behavior, what did that entail? What did you get out of it?

So, I spent more than five years working with Dr. Agarwal during my time at University of Arkansas at Little Rock. During these five years, even before COSMOS existed, I worked on various projects. I started with the mob project, but then I also moved on to a social bots project, and also worked on analyzing disinformation/misinformation campaigns during various military exercises. Additionally, I analyzed blog sites using the BlogTracker tool and utilized social cyber forensics to study cross-media coordination. As I was leaving COSMOS to join Creighton University, we began work on the YouTubeTracker tool. I still consider myself as working with COSMOS, as I am currently collaborating with Dr. Agarwal and graduate students at COSMOS on creating a simulation model of mobs, leveraging various social science theories.

Outside your research, what else were you able to accomplish while at COSMOS?

The most momentous event as a graduate student was when my first conference paper was accepted,which I then presented at Yale University. I learned a lot during that conference and realized that the work I am doing is significant and has a meaningful impact; I began to feel like what I’m doing is having an effect on society.

Since leaving COSMOS, what kinds of work have you done? What is your current work? What positions did COSMOS and your classes at UALR best prepare you for?

After leaving COSMOS, I joined Creighton University as an assistant professor in the Department of Computer Science, Design, and Journalism, where I primarily teach undergraduate students. I was recently promoted to associate professor and granted tenure. 

I gained invaluable experience from my time at COSMOS, particularly in teamwork, which has greatly benefited me in my role as a teacher. 

For instance, most of my upper-level classes involve project-based learning, where I encourage students to start their projects early, establish milestones throughout the semester, and encourage students to collaborate with each other to ensure timely project completion. Regarding teaching, I developed a course titled Social Networks Analytics, in which I teach my students the knowledge and skills I acquired during my time at COSMOS and beyond. Also, my postdoctoral experience at COSMOS equipped me with the ability to manage multiple projects and supervise students engaged in these projects. This expertise has been instrumental in overseeing my research endeavors at Creighton University and has provided me with the necessary skills to work with my research assistants and teaching assistants effectively. 

What would be your advice for people at COSMOS and UALR now?

My advice to students at COSMOS is to keep going and never give up. Consistency is key to success. Do not be afraid to take on new projects or learn new skills; these will be the building blocks of your future career, but stay focused on your projects, too. Even if you feel like things are not paying off at the moment, they will pay off in the future. Finally, try to publish your research diligently to contribute to the scientific community, but do not forget to have fun and take care of yourself.

  • Sayantan Bhattacharya, Billy Span, and Nitin Agarwal, with 3rd place in the Graduate Research projects Poster Presentations for their project titled Solidarity to Storming: Assessing the Socio-technical Factors Behind Modern Social Movements 

Commenting on his first Expo experience, Monoarul says, “Participating in the UA Little Rock Research and Creative Works Expo is something that I looked forward to ever since I joined COSMOS.  Being in the first ever poster presentation and eventually winning an accolade from the research work that I am doing here at COSMOS will always be a cherished memory for me. This milestone would not have been possible without the unwavering support of my project team lead Mayor Inna and the invaluable guidance and supervision of Dr. Nitin Agarwal.”

Pearl, who graduates this month, also talked about her presentation, as it was her second time presenting at the Expo. “The experience was indeed a great one. I was able to effectively communicate the research objectives and results within the required ten-minute time frame, which was something I had struggled with in last year’s expo oral presentation. There were interesting questions and conversations centered around how content on social media applications and algorithms could be moderated to filter out bot manipulated content—which is one of the practical implications of our research. These conversations were a testament to how relatable people found the research, specifically from the angle of them being social media users themselves.”

Sayantan commented, saying, “Participating in the Research Expo offers us the chance to showcase our research and the year-long effort we’ve put into our work. Explaining our projects to individuals outside our field, who nonetheless value and appreciate its significance, is an immensely rewarding experience. It not only motivates us to continue pushing boundaries but also inspires us to produce even more impactful work in the future.”

Mayor Inna also remarked, “It was truly a remarkable experience—my first time delivering an elevator pitch with a strict one-minute limit. I had to carefully balance providing sufficient detail while also being concise, ensuring that every word contributed meaningfully to my message. I am glad our research is getting local recognition.”

Dr. Agarwal said, “I am extremely proud of our students and their contributions to the various research projects at the COSMOS Research Center. These awards demonstrate their team spirit and dedication to research.”

2023 Student Writing Awards

We are proud to announce an accomplishment for Cosmographer Tenzing Briggs, who in the past month was awarded the Technical and Business Category Writing Award by the Rhetoric & Writing Department for the 2023 Student Writing Awards.

The work that received the award was a style guide for Katog Choling, a religious nonprofit Buddhist center in Northeast Arkansas, created for the Fall 2022 Technical Writing and Editing course taught by Dr. Cynthia Nahrwold. In the cover letter of the style guide submitted for the 2023 Awards, Tenzing explains the challenges that come with creating such an organization’s style guide. 

“There are two key elements important to the content and its context,” Tenzing says. “As a religious organization, most Katog Choling publications are written by and for people familiar with Buddhist practice.” Tenzing highlights how this can be an issue, saying, “Katog Choling occasionally has volunteers who are novice or non-Buddist writers and editors—and the gap between their knowledge of Buddhism and more complex Buddhist theory can affect the quality of publications.” He continues, “This gap can especially affect the document design, or organization of chapters and subsections, because Buddhist practices often rely upon visual cues that indicate how to pronounce a prayer or what vocal rhythm to use—cues that a non-Buddhist editor might not realize should be implicit within the text.” One example Tenzing mentions is the visual design for mantras, saying,

“Mantras must look different than the body text within prayer booklets, because mantras are treated a specific way in Buddhist practice (e.g. having a differing spoken rhythm than the body text, or being repeated multiple times) and thus need to be instantly recognizable on the page so that the Buddhist practitioner can recite accordingly.”

“Moreover, since Katog Choling’s staff is entirely made up of volunteers, the staff and I also knew that a Style Guide would immensely help streamline operations,” says Tenzing. “There are multiple different publications being worked on by Katog Choling staff, and often the leaders of each project work independently, which can cause difficulties whenever their project encounters challenges—this style guide provides a unifying resource for helping when challenges arise, for style as well as knowledge, like how to format across Adobe products.” By recognizing these challenges, Tenzing was able to create a comprehensive Style Guide that did “not just establish style but also informed readers of the different projects running simultaneously across Katog Choling and of who to turn to for advice on tools like Adobe InDesign, WordPress, and WordPress plugins.”

This work was developed before Tenzing became a Cosmographer; it was developed throughout classes in Fall 2022 and Spring 2023, but Tenzing still feels its impact with work at COSMOS. “I’m extremely grateful for the opportunity of working at COSMOS I’ve had for the last year,” Tenzing remarked, “because my COSMOS work is the kind of editing I fell in love with in my first graduate editing courses, especially when I made the Katog Choling Style Guide.” He went on to say, “If I had not been given the chance to work at COSMOS, I would not have been able to hone my skills to my current extent for using style guides and applying stylistic edits. In my COSMOS work—where I help proofread and reformat conference or journal submissions, according to each conference’s individual style guide—I daily strengthen my editing skills.”

Tenzing finished by saying, “One thing that is amazing about work at COSMOS is how you will not only learn skills that are useful outside the classroom, but you will also learn a great many things from your research center colleagues and strengthen your ability to work cooperatively with others.”
