CNMF: A Community-Based Fake News Mitigation Framework

Fake News Mitigation via Point Process Based Intervention

We propose the first multistage intervention framework that tackles fake news in social networks by combining reinforcement learning with a point process network activity model. The spread of fake news and mitigation events within the network is modeled by a multivariate Hawkes process with additional exogenous control terms. By choosing a feature representation of states, defining mitigation a...

Fake News in Social Networks

We model the spread of news as a social learning game on a network. Agents can either endorse or oppose a claim made in a piece of news, which itself may be either true or false. Agents base their decision on a private signal and their neighbors’ past actions. Given these inputs, agents follow strategies derived via multi-agent deep reinforcement learning and receive utility from acting in acco...

Fake news threatens a climate literate world

T he year 2015 may be regarded as the most environmentally significant year in history: the Paris agreement on climate change and the 2030 agenda for sustainable development are two unprecedented international agreements that together provide a roadmap to achieve a low-carbon, climate-resilient world and to eradicate global poverty. However, given the implementation of these agreements is large...

The Economics of "Fake News"

Automatic Detection of Fake News

The proliferation of misleading information in everyday access media outlets such as social media feeds, news blogs, and online newspapers have made it challenging to identify trustworthy news sources, thus increasing the need for computational tools able to provide insights into the reliability of online content. In this paper, we focus on the automatic identification of fake content in online...
