Modelling social interactions

  • Philippa Pattison - The University of Sydney, Australia


In this talk, I discuss the application of relational event models (REMs) to the analysis of time-stamped interactions in both small and large populations (Butts, 2008). The relational event framework provides a flexible capacity to model an unfolding sequence of interactions as a function of cognitive, behavioural, social and other contextual processes. In this framework, the prior history of learning-related interactions creates the context for future learning interactions and leads to differential propensities for the occurrence of specific future interactions (Butts, 2008). In practice, the history of interactions is represented by indicators of relevant exogenous and endogenous influences, with the latter informed by the now extensive body of work on modelling social networks as the outcome of endogenous ‘local’ network processes (e.g. Snijders et al, 2006; Pattison & Snijders, 2013). Here we review this framework and its application, and present two distinctive applications: interactions among cattle and learning interactions in MOOCs.

Philippa_PattisonProf Pip Pattison is Deputy Vice-Chancellor (Education), University of Sydney. As DVC (Education), Pip is responsible for the University’s strategy and vision for teaching and learning and students’ educational experience. She oversees institution-wide development of better support for student learning, including the University’s approach to curriculum renewal, new thinking in pedagogy, learning and teaching analytics, e-learning and quality assurance for learning and teaching. Pip is a quantitative psychologist by background, whose primary focus of research is the development and application of mathematical and statistical models for social networks and network processes. Her work has broad application and has most recently focussed on the transmission of infectious diseases and the recovery of communities following the 2009 Victorian bushfires.

Detecting rumors and fake news online

  • Meeyoung Cha - Korea Advanced Institute of Science and Technology, South Korea


Social platforms are an ideal place for spreading rumors and fake news. As more people seek information and read news online, automatically debunking such false claims has become an urgent problem. Recent years have seen great advances in data-driven rumor research. This talk will review some of its major developments, including how a comprehensive set of user, structural, linguistic, and temporal features help us better understand their propagation processes. In detecting rumors and fake news in the wild, time becomes a critical factor. This talk will present how the significance of features changes by time and which features are prominent for early detection. I will also highlight the latest detection studies with deep learning techniques.

Enabling AI Applications by Network Analysis and Mining: from Algorithms to Systems and from Academia to Industry

  • Jian Pei - Simon Fraser University, Canada
    Springer SNAM Journal Keynote


Unprecedentedly more and more AI applications are enabled by network analysis and mining. Many new algorithms have been proposed, partly by academic research, and are adopted actively by industry. Those algorithms extract knowledge at the macro and micro levels. When applying those algorithms to problems in practice, a series of challenges ranging from algorithms to systems need to be addressed. In this talk, I will conduct a random walk and present a few anecdotes about related topics on algorithm and system aspects and from academia and industry angles, such as implementability of network analysis algorithms, building industry scale cloud-based graph computing engines, integration and exchange of graph data, and driving business actions using network analysis and mining.

Deep User Understanding for Building Intelligent Bots

  • Xing Xie - Microsoft Inc., China


With the rapid development of positioning, sensing and social networking technologies, large quantities of human behavioral data are now readily available. They reflect various aspects of human mobility and activities in the physical world. The availability of this data presents an unprecedented opportunity to gain an in depth understanding of users. In this talk, I will first introduce why understanding user demographic and personality attributes is important for building intelligent bots. Then I will show the predictive power of human mobility data for inferring users’ demographics. Afterwards I will present our work on understanding different types of user personality traits based on heterogeneous user data. Finally, I will describe the application of our technologies in Microsoft XiaoIce, on profiling XiaoIce users, recommendation in conversations, and personalized conversation generation.
