PHEME Project at EDF 2015

The document discusses the PHEME project, which focuses on verifying the veracity (truthfulness) of information on social media as the "fourth challenge of big data" beyond volume, velocity, and variety. It aims to help analyze rumors and their trustworthiness by developing techniques like rumor detection and classification, modeling how claims spread across networks over time, and creating visualization tools. The goal is to help journalists and healthcare by providing open-source social intelligence and helping evaluate unreliable health-related claims patients may encounter online.

PHEME http://www.pheme.eu Phemes & social media Memes are thematic motifs that spread through social media in ways analogous to genetic traits We coined the term phemes to add truthfulness and deception to the mix 2 http://en.wikipedia.org/wiki/Pheme PHEME focuses on a fourth crucial, but hitherto largely unstudied, challenge: Veracity
- 3. PHEME http://www.pheme.eu Rumour analysis: The Problem Now mostly manual Rumours are challenging Some rumours could take hours, days, weeks or even months to die out Ill-meaning humans can currently outsmart computers (and humans) and appear genuine
- 4. PHEME http://www.pheme.eu Rumour analysis: The Problem Mike Brown shot by police in Ferguson We have different rumors emerging from the topic We dont know if they are true. We see the spikes and sometimes they come back (different temporal dynamics) We need to understand the overall conversation to see the different points of view and how the rumours go forward

Ontologies for modelling phemes Use a priori knowledge (LOD) and reasoning to detect contradictions Model phemes spread across media, social networks, and time Conversational analysis Real-time rumour classification Pheme visualisation to support veracity checking: media maps, impact maps, geographical maps
