“…Gender differences were also observed, with men being more active in seeking. Focusing more on the technical perspective regarding the problem of identification of fact-checkable tweets posted during a particular disaster event, Barnwal et al (2019) described the findings of focus groups using Twitter data on the 2015 Nepal Information behavior during Covid-earthquake, leading to an algorithm that provides highly fact-checkable tweets containing specific references. Jang and Baek (2019) studied how the credibility of information from public health officials is associated with people's reliance on a particular communication channel in the context of the 2015 Middle East Respiratory Syndrome (MERS) outbreak in South Korea.…”

“…Studies have been conducted e.g. for the Zika outbreak (Southwell et al, 2016) or the Tibet earthquake (Barnwal et al, 2019). Research shows how people react when they need more information and how they try to accommodate their needs for immediate action, but also for a better understanding of the situation.…”

PurposeThe purpose of this study is to explore the impact of the Covid-19 crisis at the level of individual information behavior among citizens from the German-speaking countries, Austria, Germany and Switzerland.Design/methodology/approachAn online survey was conducted among 308 participants gathered through convenience sampling in April and May 2020, focusing on how citizens changed their mix and usage intensity of information sources and according to which criteria they chose them during the Covid-19 crisis. A Wilcoxon signed-rank test was used for testing central tendencies. Effect sizes were considered to support the interpretation.FindingsThe results show first that the Covid-19 crisis has led to an increased demand for reliable information. This goes alongside a significant increased use of public broadcasting, newspapers and information provided by public organizations. Second, the majority (84%) of the participants reported being satisfied with the information supply during the Covid-19 crisis. Participants who were less satisfied with the information supply used reliable sources significantly less frequently, specifically public television, national newspapers and information provided by public organizations. Third, the amount of Covid-19-related information led some participants to a feeling of information overload, which resulted in a reduction of information seeking and media use.Originality/valueThis paper is one of the first to analyze changes of information behavior patterns of individuals during crises in the current information environment, considering the diversity of resources used by individuals.

“…The track was motivated by the TREC Microblog Track [11] which focuses on evaluating microblog retrieval methodologies in general. The objectives of the FIRE 2016 Microblog track were twofold- (1) to develop a benchmark dataset for evaluating microblog retrieval methodologies, and (2) to evaluate and compare the performance of various IR methodologies over the test collection.…”

In last few years ,microblogging sites like Twitter have been evolved as a repository of critical situational information during various mass emergencies. However, messages posted on microblogging sites often contain non-actionable information such as sympathy and prayer for victims. Moreover, messages sometimes contain rumors and overstated facts. In such situations, identification of tweets that report some relevant and actionable information is extremely important for effective coordination of post-disaster relief operations. Thus, efficient IR methodologies are required to identify such critical information. Additionally, cross-verification of such critical information is a practical necessity to ensure the trustworthiness. To this end, we organized the 'Information Retrieval from Microblogs during Disasters (IRMiDis)' shared task with the FIRE conference for consecutive 3 years (2016, 2017 and 2018). In each year's track, we have given task associated with extraction of a specific situational information to aid post-disaster relief operation and asked the participants to propose methodologies. Our present study provides a brief description of the tasks (research problem) given in these tracks, a summary of methodologies of all submitted runs and finally a brief description of our proposed methodologies to address the research problems of IRMidis track.
