Incorporating Diversity in Teams for Successful Collaboration
We attend in-person events but often forget who we met and where. We receive many contact requests in our online social networks like LinkedIn and Facebook from people we do not know. How can we make it easier for people to connect from offline to online? In this workshop, we will discuss:
Cutting-edge research on connecting people through offline and online interactions and how technology facilitates these transitions.
Strategies for incorporating diversity into the development of mobile social networking applications.
Establish a multidisciplinary and diverse network in mobile social networking, involving experts from academia, industry, and Chicago's inclusive populations across computer science, sociology, and human-computer interaction.
This event will feature a Distinguished ACM Speaker, Anura Jayasumana, Professor, Electrical & Computer Engineering, and Computer Scienceat Colorado State University.
Talk title:
Emergent Patterns in Social Networks
Abstract:
Detecting latent or emerging patterns in dynamic networks is crucial across multiple domains, including homeland security, consumer analytics, behavioral health, and social computing. However, dynamic network data presents unique challenges in collection, mining, analytics and processing. We will present INSiGHT (Investigative Search for Graph Trajectories), a comprehensive framework for detecting emergent patterns of behaviors in knowledge networks containing social and behavioral data, with a focus on detection of domestic radicalization. To account for recurring behavioral indicators and the recency of behaviors as the imminence of a threat, e.g., INSiGHT provides parameterized methods to score multiple occurrences of indicators and to dampen the significance of indicators over time. Recognizing that radicalization can occur within small groups or collective plots, INSiGHT employs a non-combinatorial neighborhood matching technique that enables analysts to identify clusters of individuals potentially engaged in conspiracies. Our approach combines advanced natural language processing (NLP) and supervised machine learning models to classify textual data for radicalization indicators. Additionally, we have developed PINGS (Procedures for Investigative Graph Search), a specialized graph database library tailored for investigative search in social network mining. Finally, we will explore the potential of emerging Graph Neural Networks (GNNs) and Graph Embedded Neural Networks (GENNs) to pave the way for more advanced analytical capabilities in dynamic network analysis.
