The Covid Check project aims to help optimize official communication and clarify the main issues of the Portuguese about the pandemic, through the creation of a public knowledge network that will be available through a specific website. In this way it can contribute to the optimization of the effective results of communication protocols between health entities and their stakeholders, at internal level, and journalists and citizens, at external level. The expected results are: the promotion of effective and clear messages among the population; contribute to the identification of disinformation that may be harmful to public health; and encourage society to search for reliable sources. To achieve this: entities must improve their communication based on research results; the media must create more focused messages; citizens must understand the practices and behaviours desired to resolve the pandemic. The project is part of the research on desinformation on course in the MediaLab_Iscte.

The main focus of the project is to monitor propaganda and disinformation activities on online social media networks with the objectives of mobilisation, polarisation and political destabilisation in Portugal, regardless of the origin of these activities. Throughout the project period, which corresponds to a moment of great political activity in Portugal, marked by three elections (European, Regional - Madeira and Legislative), an attempt was made to identify and analyse organised movements, political party’s related or not, of propaganda and disinformation with the aim of influencing the informed participation of citizens in the elections. Social network analysis methodologies and tools (i.e. Crimson Hexagon, Netvizz, Google Trends, etc.) will be used to identify, transversally and longitudinally, messages and information dissemination networks with malicious objectives and their international relationships, with special attention to the relations between populist movements and their sharing of messages of misinformation ("fake news"). The final objective is to identify messages, protagonists and channels of disinformation that seek to influence political discourse through the main public online social media networks (Facebook, Twitter and Youtube). The project also aims to contribute to the warning and prevention of the dissemination of malicious propaganda, collaborating with journalistic projects to develop and disseminate the results of research.  Regarding WhatsApp, as it involves the integration of public access groups via an access link, it is expected to replicate the methodology used by Resende et al (2019) that addressed the same phenomenon in Brazilian elections. The anonymization of the personal data of the participants of the groups (phone number, photo and other information associated with the profile) will be made in the collection process, thus not integrating the analysis of the results. This anonymisation of the data in the collection process...
