TL;DR
It is found that AI assistance increases accuracy by 3-7% when participants viewed the relevant video segment, and by 27-35% when they did not, while efficiency increases by 10% for short videos and 25% for longer ones, and self-reported confidence in answers remains stable across all three conditions.
Abstract
The ubiquity of multimedia content is reshaping online information spaces, particularly in social media environments. At the same time, search is being rapidly transformed by generative AI, with large language models (LLMs) routinely deployed as intermediaries between users and multimedia content to retrieve and summarize information. Despite their growing influence, the impact of LLM inaccuracies and potential vulnerabilities on multimedia information-seeking tasks remains largely unexplored. We investigate how generative AI affects accuracy, efficiency, and confidence in information retrieval from videos. We conduct an experiment with around 900 participants on 8,000+ video-based information-seeking tasks, comparing behavior across three conditions: (1) access to videos only, (2) access to videos with LLM-based AI assistance, and (3) access to videos with a deceiving AI assistant designed to provide false answers. We find that AI assistance increases accuracy by 3-7% when participants viewed the relevant video segment, and by 27-35% when they did not. Efficiency increases by 10% for short videos and 25% for longer ones. However, participants tend to over-rely on AI outputs, resulting in accuracy drops of up to 32% when interacting with the deceiving AI. Alarmingly, self-reported confidence in answers remains stable across all three conditions. Our findings expose fundamental safety risks in AI-mediated video information retrieval.
MultiVENT-Raw is released, a multilingual collection of nearly 120,000 primarily raw videos paired with 130 events and 222 event-centric queries, along with human-annotated video relevance judgments and human-extracted key facts for relevant videos.

Online video platforms can expose young users to harmful content, but independent audits remain difficult because video annotation is costly and moderation judgments vary across languages. We audit TikTok in France, Italy, and Sweden with sockpuppet accounts representing four age personas (13, 16, 19, 40), collecting 3...
This research examined how public communication about emerging technologies is shaped through platform-specific multimodal conventions and engagement dynamics on TikTok to provide insights for stakeholders who seek to promote responsible AI communication on video-sharing platforms where algorithms shape which content i...

Over twenty editions, the ICWSM community has examined social life online as platforms, interactions, and research methods have changed. What can this body of research tell us at this critical juncture, as AI increasingly reshapes how people communicate online? We analyzed 2,139 indexed contributions from 2007 to 2026,...
In recent years, media attention has focused on artificial intelligence, particularly on chatbot services and generative intelligence. ChatGPT, created by OpenAI, was one of the earliest online tools and rapidly gained popularity. Users are indeed exposed to a service with privacy notifications and conditions of use th...

This work introduces WildSEEK, a manually annotated dataset of 3k information-seeking queries from real user interactions, and an evaluation framework for LLM-generated responses, and finds that over a third of information-seeking queries are high-risk and more often analytical.
