Abstract: In this paper, sentiment analysis is used to investigate the prevailing sentiment of posts on Twitter (X) in the Croatian language in 2022. In accordance with the restrictions, five popular topics in Croatian public discourse were formed, each of which consists of several searched terms, i.e. posts containing that term. The terms were found by checking several internet portals that post news articles in combination with an overview of Google trends in the Republic of Croatia in 2022. The first topic is domestic politics and contains posts about the most important actors within it and the initiators of certain politically formed groups, the second topic contains posts about various domestic news that were discussed during 2022, the third topic contains posts related to foreign politics and news, primarily the USA, Russia and Ukraine and their representatives. The fourth topic contains posts with terms related to Croatian sports in 2022, of which the majority of posts are related to the football world cup in Qatar. The last topic contains posts related to social changes in the Republic of Croatia during 2022. This topic is also the one with the largest share of negative posts. In addition to topics, the paper contains an overview of the overall prevailing sentiment and its changes during the year. Sentiment analysis was based on a customized, broad dictionary CroSentiLex which contains sentiment values of words, and was performed at the level of individual words and at the post level. The results show a prevailing negative sentiment in all topics except sports, therefore the negative sentiment prevails overall.
