“ WeVerify aims to address the complex content verification challenges through a participatory verification approach, open source algorithms, low-overhead human-in-the-loop machine learning and intuitive visualizations. Social media and web content will be analysed and contextualised within the broader online ecosystem, in order to expose fabricated content, through cross-modal content verification, social network analysis, micro-targeted debunking and a blockchain-based public database of known fakes.
We develop technologies and services for the detection of deep fakes, the identification of multimedia reuse, the improved understanding of social media context around online images and videos, and the visualization of social media discussions on topics affected by disinformation.

“ In this context, the main objective of the TENSOR project is to provide a powerful terrorism intelligence platform offering LEAs fast and reliable planning and prevention functionalities for the early detection of terrorist organised activities, radicalisation and recruitment. The platform integrates a set of automated and semi-automated tools for efficient and effective searching, crawling, monitoring and gathering online terrorist-generated content from the Surface and the Dark Web.
Our team developed the image forensics component of the TENSOR platform, with the goal of helping analysts detect and localize digital manipulations on images.

“ We develop tools and services that aid in Social Media verification. We look at verification from a journalistic and enterprise perspective.
We developed methods and tools that supported the multimedia verification needs of the REVEAL platform. These include a web multimedia crawler, a media clustering and summarization component, an image verification assistant based on image forensics, a tweet verification assistant based on semi-supervised learning, a Twitter account classification service based on graph embeddings, and a text-based location estimation service based on language models.

“ SocialSensor offers technologies for analyzing the activity in social networks with the goal of discovering trending and high-quality content, identifying influencers, sentiment around discussed topics, and establishing links between different online sources. In addition, the project creates new means of retrieving, delivering and presenting media content and information in easily digestible ways and in mobile settings.
Our team prototyped a real-time framework for collecting, mining and searching streams of social multimedia content. This includes services for topic and event detection, community detection and analysis, large-scale multimedia indexing and search, and a web-based dashboard for social media analytics.
