When an earthquake hits, the dissemination of tsunami warnings can be crucial in saving lives. Unfortunately, some dissemination channels may be insufficient as they may be affected by the earthquake itself (damaged, loss of power or overloaded), may be expensive to build and are not available at certain places. In this research we propose a tsunami warning dissemination system that can serve as an...
The social media generates large volume of data through tweets and text messages during and after any disaster. The analysis and classification of the obtained data at the time of disaster is essential for conveying the information to the appropriate rescue personnel. In this paper, an automated text classification system is proposed in order to classify the data effectively. The classification of...
The purpose of this study is to provide an understanding of how the Bangkok Metropolitan Administration (BMA) in Thailand has adopted Twitter to communicate with residents in its approach to flood management. Specifically, we examine 3,453 BMA tweet messages in terms of quantity, tweet content, reactions and engagement. Results indicate that BMA actively provides information of various types that...
Emergency resources are often insufficient to satisfy the demands for professional help and supplies in the wake of a public disaster. The authors provide insights into the trends, innovations, and challenges of contemporary crowdsourced e-health and medical informatics applications in the context of emergency preparedness and response.
When a crisis or a disaster occurs, first responders, news agencies and the victims often use social media to disseminate situational information. However, authorities involved in disaster management are still not comfortable in using social media data to take decision, since right kind of situational information in a consistent manner is difficult to extract from the unstructured and often unreliable...
In this research, we propose a Common Infrastructure System for the disaster countermeasures headquarters to transmit disaster information to residents speedily at the time of large-scale natural disaster. A Common Infrastructure System realizes digitization of the disaster information concentrated in the disaster countermeasures headquarters. And, this system extracts only the information, which...
In times of a crisis, disasters or extreme events, affected people use social media solutions to share information about the situation. Hence, the use of this information for supporting humanitarian operations is becoming a valuable source to develop a real time understanding about the situation even before they arrive at the ground. From a scholarly perspective, the use of social media management...
The aim of this minitrack is to provide a forum for discussion on methodologies, solutions, and issues related to decision analytics in humanitarian operations research. Submissions were invited covering the general area of providing analytical capabilities for decision support.
Communication technologies and approaches, such as mobile applications and social media enable individuals to share information with others ubiquitously. These voluntarily created data contain geographic information as well as user generated content such as images or text. Researchers and practitioners can gain highly valuable information by analysing and combining those different types of data. Earlier...
Social media offers the opportunity to connect with the public, improve situational awareness, and to reach people quickly with alerts, warnings and preparedness messages. However, the ever increasing popularity of social networking can also lead to ‘information overload’ which can prevent disaster management organizations from processing and using social media information effectively. This limitation...
Social media sites are playing a significant role in rapid propagation of information when disasters occur. This effective communication platform is a great useful tool for emergency (disaster) management agencies during all phases of disaster management life cycle: prevention (mitigation), preparedness, response, and recovery. This study has conducted a systematic review of social media use in disaster...
The use of social media is now prevalent in all aspects of society. Each and every major news event is accompanied by a stream of real-time social media posts, creating a vast and ever changing data supply -- a hallmark of big data. The aim of the ATHENA project is to turn this stream of information into a vital resource for the public and first responders during a crisis. ATHENA recognizes that citizens...
This HICSS-47 Minitrack Introduction introduces the four papers accepted by the ICT-enabled Crisis, Disaster & Catastrophe Management Minitrack within the HICSS E-Government Track.
Twitter demonstrated its value as a viable substitute to traditional communication channels during the recent disasters. However, little is written about Twitter in government for an early disaster warning system. In this exploratory empirical research, we aim to address the question: How does the government use Twitter to inform the public about disaster hazards and vulnerability? Case study and...
In this paper we discuss the role of Open Source Intelligence (OSINT) in Disaster Management. In particular we present the use of the Sail Labs Media Mining System in the context of disaster relief operations and use samples to point out advantages and strengths of the MM-System. Future challenges in research and further development of this field are addressed towards the end of the paper.
The collection and dissemination of increasing quantities of information representing multiple digital media objects are promising, combined with a number of technical advances in ICT. Even though the information is maintained and distributed by different owners, systems, formats and locations, their contents might tell the same story, share the same space-time extension, and they might be closely...
Our understanding of the impacts of social media on individuals who receive warnings of extreme events is limited. There is to date no uniform approach to integrating social media as part of emergency management strategies. This research addresses the question of the role of social media in the effectiveness of the warning response process in the context of a naturally occurring experiment. The results...
There is a widespread agreement that the mass media are a powerful and important source of people's perception of the world, the world of foreseen or unforeseen disasters and risk being no exception. Within disaster management the national media system is an especially important means of disseminating warnings and information. However, media organisations have their own logic and goals that are not...
The goal of this article is to serve as a primer of disaster public relations. It will explain the requirements of the media and how best to incorporate their ubiquitous presence to the advantage of the disaster team, including how to give an effective interview, how and where to establish a media center, and the importance of sensing what will make the strongest visual or textual impact.In any disaster...
