Technology for “Data Journalism” activities
The project is aimed at designing and implementing technologies for data-driven journalism activities
In the modern digital age methodologies for professional Big Data analytics represent a strategic necessity to make information resources available to professional journalists and media producers in a more effective and efficient way and enabling new forms of production like data driven journalism. The challenge lies in the ability of collecting, connecting, analysing and presenting heterogeneous content streams accessible through different sources, such as digital TV, the Internet, news agencies, social networks and media archives, and published through different media modalities, such as audio, speech, text and video, in an organic and semantics-driven way.
This project defines and implements components and systems for professional information services that address these challenges with a uniform and holistic approach. At the core of the approach there is a set of artificial intelligence techniques and advanced statistical tools to automate tasks such as information extraction and multimedia content analysis targeted at discovering semantic links between resources, providing users with text, graphics and video news organized according to their individual interests. The system allows to define customized search profiles that are automatically and dynamically updated with the relevant contents found in the monitored information sources, which include Web feeds, television channels and specialized circuits such as the Eurovision News Exchange Network (EVN), or legacy archives.
More recently, starting from 2016, the project (in collaboration with Rai Digital) focused on identifying an end-to-end workflow for data driven journalism. Such a workflow foresees the design, implementation and the integration of fundamental components related to the data refining, to the data analysis (maths-statistics), to the structured and machine-readable creation of the story, open data management and advanced visualisation.

Deep Networks in Content Management Systems
The recent technological advancement of computing systems allows today to find computers with extremely advanced numerical processing capabilities. In particular, the use of Graphics Processing Units (GPUs) for image and multimedia content processing and classification is experiencing a phase of intense development thanks to the deep-seated scientific research conducted in recent years (Deep Learning). Deep Learning is a branch of Machine Learning that uses complex neural networks for a variety of applications. Among these, the application area of automatic classification of audiovisual content is certainly one of the most interesting from the strategic point of view for RAI.
