What can data from blogs and social networks tell about users? Is it possible to develop mechanisms of dissemination of information that will help to recognize fakes? Specialists from more than ten universities and organizations of the world are working on these and other tasks within the large European project RENOIR. The main goal of the project is to create new methods of processing social information. Joanna Toruniewska, PhD student from the Warsaw University of technology, came to ITMO University to work within the project. She told ITMO.NEWS about her work and how computer science can help you with processing social information.
