Analýza šíření zpráv na Twitteru

The bachelor thesis deals with the topic of message dissemination on social networks, with a focus on Twitter. The theoretical part describes the characteristics of users on social networks, information sharing and the influence of influencers. Furthermore, related issues such as the formation of social bubbles and misinformation are discussed. The second part of the thesis focuses on Twitter, its recent changes, and also presents possible ways of collecting data from this social network. The practical part is dedicated to the analysis of messages related to Hogwarts Legacy. The aim is to identify the messages that are most widely disseminated among users. Data from the social network Twitter was collected using the tool Apify. The data was then analyzed based on several aspects, such as the centrality of users or the sentiment of the post. From the selected subset of data with negative sentiment, a network visualisation was created, showing the main message disseminators. The conclusion is that the most viral posts are humorous posts and parodies, often in the form of short videos. Political criticism of the game was also widespread, mainly due to the views of its author J.K. Rowling. Another finding was that false news is spread more than objective news, and that the authors of the posts with the most shares are random users with fewer followers, rather than verified sources.
