Terrori-isku tiedontarpeiden virittäjänä: Turun puukotusten aiheuttamat tiedontarpeet

In this study, we have analysed what kind of information needs arise in case of a sudden random act of violence and which factors trigger these information needs. The case represented in this study is the stabbing in Turku which took place in August 18th, 2017, which led to the death of two people. The data in this study consists of the Facebook comments collected from the media company Yle News’ Facebook-page. The first 13 posted news and their comments were collected during the first eight hours after posting the news. The total data consists of 1930 comments and 212 recognized information needs in their content. Quantitative and qualitative analysis were used for analysing the data. The study shows that, during crisis, information needs change as more information is released. Most information needs were directed to the media and especially the activities of media company Yle. Other frequent information needs included questions about the offender and issues concerning immigration politics. In the study, information needs were categorized into 15 different types that can be divided in to four main groups: authority related, act related, world view related and other information needs.
