Seminar overview

The explosion of data coming from online sources presents enormous opportunities for researchers and evaluators to study many aspects of human behaviour at unprecedented scale. However, these datasets are fundamentally unstructured or semi-structured, and require extracting insights from complex data formats like text and images. This presents a challenge for data scientists, researchers and evaluators. So, how should the resulting models and analytics applied to large-scale online datasets be evaluated? What role is there for using these approaches to inform research and evaluation? This talk will focus on text-based data from online social media sources, describe some of the typical data science techniques used to gain insights, and discuss possible approaches used to understand when these techniques might provide options for evaluators and researchers.
