Title:    

Knowledge Graphs based Misinformation Detection on Counterfactual Claims about Climate Change 

Abstract:    

Climate change is a crisis that requires global action. As social media significantly impacts people's opinions, it is essential to reduce the harmful misinformation about climate change spreading there. However, a single AI approach is not enough for misinformation detection (MD), especially for counterfactual claims.

In this project, we aim to develop a system that will apply NLP techniques to parse a given counterfactual claim and then query knowledge graphs (KGs) to get evidence for the MD in the climate change domain. In addition, probability will be computed to represent how much the conclusion is trusted. In this talk, we will present the designed system, the current progress and then summarise future work.

Title:

Income precarity: who is at risk?

Abstract:

Concept of precarity is being extended to later life in emerging research. This in part includes issues around persistent vulnerability in income. In this research, risks of income vulnerability in later life are explored with the aid of latent class growth modelling techniques, using the English Longitudinal Study of Ageing data.
