The 6th Workshop on Graph Techniques for Adversarial Activity Analytics (GTA³ 2022)

December 17, 2022 | Virtual Conference - Osaka, Japan

For past GTA³ workshops, please visit our archive page.

Theme & Purpose

Graphs are natural analytic tools for modeling adversarial activities across a wide range of domains and applications. Examples include sensing online influence campaigns through social networks, detecting threats and vulnerabilities in cyber-physical networks, preventing disease spreading, and combating covert illicit activities, such as smuggling and arms trafficking, that span across multiple networks (e.g., financial, communication, and transportation networks). The main purpose of this workshop is to provide a forum to discuss research problems and novel approaches on graphs, with emphasis on addressing the three fundamental problems for modeling adversarial activities - “Connecting the dots”, “Finding a needle in a haystack”, and “Defending against attacks”. Besides the traditional activity-centric networks that have been the main focus of this workshop, semantic networks (e.g., knowledge graphs) recently drawn significant attention in our research community. Thus, an important question is to extend existing graph computing capabilities to handle semantically rich networks to support the emerging research direction. The workshop (co-located with the 2022 IEEE Big Data) aims to bring together a community of researchers, from both academia and industry, to share their experiences and exchange perspectives for future research directions. We also hope the workshop will serve as a medium to facilitate future collaborations among interested audiences and researchers.
