Abstract: In this paper we present the Reconstruction and Exploration approach (R&E) and F-REX tool and their applications in a field exercise with the Swedish Rescue Services Agency with the purpose of investigating features needed for a computer supported approach for evaluation of large scale crisis management operations. After the exercise several interviews and one seminar were held to evaluate R&E as a representative for computer supported evaluation approaches for crisis management operations. Initial results indicate that multimedia presentation of key events from an operation can be very valuable not only to stimulate the participants to reflect on their own performance, but also to document and share lessons learned to non-participants.

Abstract: Sentiment analysis has been widely researched in the domain of online review sites with the aim of generating summarized opinions of product users about different aspects of the products. However, there has been little work focusing on identifying the polarity of sentiments expressed by users during disaster events. Identifying sentiments expressed by users in an online social networking site can help understand the dynamics of the network, e.g., the main users' concerns, panics, and the emotional impacts of interactions among members. Data produced through social networking sites is seen as ubiquitous, rapid and accessible, and it is believed to empower average citizens to become more situationally aware during disasters and coordinate to help themselves. In this work, we perform sentiment classification of user posts in Twitter during the Hurricane Sandy and visualize these sentiments on a geographical map centered around the hurricane. We show how users' sentiments change according not only to users' locations, but also based on the distance from the disaster.

Abstract: In 2004, Information Systems for Crisis Response and Management (ISCRAM) was a new area of research. Pioneering researchers from different continents and disciplines found fellowship at the first ISCRAM work-shop. Around the same time, the use of social media in crises was first recognized in academia. In 2018, the 15th ISCRAM conference will take place, which gives us the possibility to look back on what has already been achieved with regard to IT support in crises using social media. With this article, we examine trends and devel-opments with a specific focus on social media. We analyzed all papers published at previous ISCRAMs (n=1339). Our analysis shows that various platforms, the use of language and coverage of different types of disasters follow certain trends – most noticeably a dominance of Twitter, English and crises with large impacts such as hurricanes or earthquakes can be seen.

Abstract: After a risk has manifested itself and has led to an accident, valuable lessons can be learned that can be taken into account to reduce the risk of a similar accident occurring again. This calls for accident analysis methods. In the past 20 years a large number of accident analysis methods have been proposed and it is difficult to find the right method to apply in a specific circumstance. We conducted a review of the state of the art of accident analysis methods and models across domains. We classify the models using the well-known categorization into sequential, epidemiological and systemic methods. We find that these classes have their own characteristics in terms of speed of application versus pay-off. For optimum risk reduction, methods that take organizational issues into account can add valuable information to the risk management process in an organization.

Abstract: Crowdsourced Geographic Information (CGI) has emerged as a potential source of geographic information in different application domains. Despite the advantages associated with it, this information lacks quality assurance, since it is provided by different people. Therefore, several authors have started investigating different methods to assess the quality of CGI. Some of the existing methods have been summarized in different classification scheme. However, there is not an overview of the methods employed to assess the quality of CGI in the absence of authoritative data. On the basis of a systematic literature review, we found 13 methods that can be employed to this end.

Abstract: Early Warning Systems (EWS) are crucial to mitigating and reducing disaster impacts. Furthermore, technology and information systems (IS) are key to the success of EWSs. This systematic literature review investigates the research topics and themes from the past six years of Information Systems for Crisis Response and Management (ISCRAM) conference proceedings and seeks to identify the research developments and directions for EWSs to steer a discourse to advance the research in this field. Findings from a sample size of 60 papers show that there are technical, social, and topical considerations to using and advancing technology for EWSs. While technology has advanced EWSs to new levels, it is important to consider the influence of technology in the successful operation of EWSs. The results are based on the ISCRAM proceedings literature and may be broader or have different prioritization if a wider disciplinary body of literature was explored. This will be considered in the future.

Abstract: Natural or man-made disasters frequently occur in different countries and disaster types and consequences might differ immensely depending on that country's unique characteristics. While probability of a man-made disaster occurrence will be high for technologically advanced countries as a result of using technology in almost every aspect of daily life, probability of natural disaster occurrence will be dependent on geological, geographical, and climate related factors. Based on their different risk types and levels, each nation should create their own National Emergency Management Model (NEMM) and because of country specific conditions each plan must be unique. Thus, for each country NEMM should be focusing on different factors which are important and should show that country the importance list of factors. As a result, countries may better distribute their limited resources to reach optimum emergency management plan and execution. In this study, our goal is to three fold. Our first goal is to come up with full list of categories and factors which are important for a successful National Emergency Management Model. In order to achieve this goal, we determined our categories and factors based on our analysis of previous disasters and literature review. The second goal is to determine the importance level of each category and defining critical success factors for different countries. For this purpose, we are planning to use experts from different countries. This part of study is still underway. Finally, we analyze how information systems might be utilized for each category and factors to support a better National Emergency Management Model. This is a first step of a multi-step research.

Abstract: In this paper, methodological issues in research and training of complex command and control structures in emergency management are addressed. In particular, a methodological approach combining real-time role-playing exercise, after action review and observations is presented. An explorative study-ALFA-05-utilizing this approach is described. A brief overview of methodological aspects of preparation and execution is given. Further, experience gained and methodological lessons learned are also discussed. Finally, real-time role-playing exercise in combination with other methods is suggested as a feasible method for researchers and exercise managers to tackle present and future command and control in complex settings, where interaction and communication are in focus. In addition, areas for further development of the real-time role-playing exercises as a research method are suggested.
