The 7th Workshop on Graph Techniques for Adversarial Activity Analytics (GTA³ 2023)

December 15, 2023 | Sorrento, Italy (Hybrid)

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 strengthening the resilience and robustness of cyber networks, identifying and responding to threats and vulnerabilities in critical infrastructure, and combating covert illicit activities, such as smuggling and arms trafficking, that span across multiple domains (e.g., finance, communication, and transportation). 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 activity-centric networks that have been the main focus of this workshop, text-rich networks and semantic networks (e.g., knowledge graphs) have drawn significant attention in our research community. Thus, an important objective involves enhancing the current graph computing capabilities to effectively handle these networks. Additionally, there is a need to investigate how the latest advancements in research, such as generative AI (GenAI) and large language models (LLM), can be leveraged to analyze these networks. This workshop 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.
