Fields of research
Research interests
-
Misinformation
Understanding how people interact with misinformation on social media and using AI to mitigate its spread online.
-
Crowdsourcing and Human Computation
Improving the efficiency and effectiveness of human-in-the-loop systems.
-
Big Data Analytics
Designing algorithms and systems that can scale-out to large amounts of data.
-
AI for Public Good
Using Artificial Intelligence methods for societal and environmental purposes. For example, stopping the spread of misinformation online and identifying chimpanzee in videos for preservation purposes.
Research impacts
The research led by A/Prof. Demartini focuses on improving the efficiency and effectiveness of human-in-the-loop artificial intelligence (AI) systems with application of AI for public good. The application domains of his research include text analytics and the intersection between structured (e.g., knowledge graphs) and unstructured (e.g., text) digital content. During his research career he has collaborated with colleagues from several industry and governmental organizations like for example, Facebook, Google, Microsoft, Yahoo!, IBM, SAP, and The National Archives in the UK.
