From Perpetrators' Digital Footprints to Behavioral Communities: An Ontology-Driven Framework for Bengali Cyberbullying Analysis--- FULL VERSION

The paper introduces ODCBNA, an ontology-driven framework for analyzing Bengali cyberbullying that integrates ontology design, knowledge graph construction, behavioral modeling, community detection, and influence modeling. Using the BenCoDiC corpus, it identifies 1,063 perpetrators, builds a 64‑dimensional behavioral profile for each, and constructs a weighted network with 27,554 edges. Louvain clustering reveals six communities and 27 sub‑communities, with Video, Impact, and User Profile features driving similarity, and influence analysis shows modest gains across communities with various seed‑selection methods.

BenCoDiC: A Large-Scale Contextual Cyberbullying Corpus for Bengali Political News Discourse FULL VERSION

The paper introduces BenCoDiC, a large Bengali cyberbullying corpus focused on political news discourse. It contains 50,250 textual instances from 100 YouTube videos, preserving caption–comment–reply relationships and organized via a nine‑dimensional star schema. A two‑tier human annotation process achieved high reliability (Fleiss' κ = 0.86, Krippendorff's α = 0.86), and transformer experiments show that adding conversational context modestly improves classification over isolated text.

Do Social Patterns Hold in Synthetic Data? Analyzing Cyberbullying Dynamics in LLM-Generated and Authentic Dialogues

The paper investigates whether large language models (LLMs) can generate synthetic cyberbullying conversations that replicate the social dynamics of real interactions. Using a comprehensive framework, the authors compare authentic dialogues with synthetic ones from GPT, Grok, and LLaMA across structural, linguistic, affective, and temporal dimensions, and conduct human evaluations of realism. Results show that while LLMs preserve high‑level interaction patterns, they systematically distort finer‑grained social phenomena, with model‑specific biases such as GPT’s suppression of harmful content and Grok’s amplification of aggression.

It Takes a Forum: Resources & Stakeholders Sustaining the Online Synthetic Non-Consensual Intimate Image Creation Ecosystem

The paper analyzes how malicious actors create and share synthetic non-consensual intimate images (SNCII) across online forums, focusing on 4chan and Reddit. By examining over 280,000 4chan comments and 78,000 Reddit posts, the study identifies a wide array of resources—including 156 LoRA files targeting 141 female celebrities and 54 commercial nudification apps—used by both highly technical and less sophisticated users. The findings show that knowledge transfer between experts and newcomers fuels the spread of these illicit resources, revealing gaps in current regulatory frameworks and suggesting intervention points to deter such activity.

Harmful YouTube Video Detection: A Taxonomy of Online Harm and MLLMs as Alternative Annotators

The paper presents a new taxonomy for online harm on video platforms, expanding existing frameworks to multimodal contexts and defining six content-based categories: Information, Hate and harassment, Addictive, Clickbait, Sexual, and Physical harms. It also evaluates multimodal large language models (MLLMs) as alternative annotators, comparing GPT‑4‑Turbo, non‑trained crowdworkers, and trained human annotators on a dataset of 19,422 potentially harmful YouTube videos. The study finds that MLLMs can perform comparably to human annotators in both binary and multi‑label classification tasks, suggesting potential applications in content moderation and social science research.

The Enforcement and Feasibility of Hate Speech Moderation

The study audits hate‑speech moderation on Twitter (now X) using 540,000 annotated tweets from a full day. Eighty percent of hateful tweets, including violent content, remained online after five months, and removal was only slightly more likely than for non‑hateful tweets, far below the rates for scams or adult content. Automated detection could not reliably classify hate but ranked it highly, allowing human triage; however, current staffing curbed little exposure, while substantial reductions were financially feasible and far below applicable regulatory fines.

Constructing an Artworld Influencers Network by Mining Social Media

The paper presents a method for building a network map of the artworld using tweets from a manually selected set of exemplar actors and NLP techniques. It identifies significant artworld actors, even those without Twitter accounts, and groups them into communities via the Louvain method while assessing their authority with HITS centrality. The resulting network demonstrates that starting from a small set of exemplars can uncover new actors and yield data that would otherwise be difficult to gather.
