Disaster Management System

Social media has redefined crisis management in the recent years. Extraction of situation awareness information from social media sites such as Twitter, Facebook, Instagram, etc. is a non-trivial task once the required framework is established. Unfortunately, most public safety authorities are still suspicious of using social media in engaging and disseminating information. This chapter reports on how social media can be effectively used in the field of emergency management along with the opportunities and challenges put forth. The chapter starts with a discussion on the functions of social media and its trustworthiness. It provides a description of the framework for disaster management system and the methodology to be adopted. The methodology consists of volunteer classification, methods of data collection, challenges faced, event detection, and data characterization with currently available disaster management tools. The chapter concludes with the division between practice and research and moves toward envisioning how social media may be used as a resource in emergency management.

<p><strong>Abstract.</strong> Due to climate changes, wildfire breakouts get more frequent and difficult to control. In the mid-July 2017, the wildfire spread from wildland to the city of Split, the second-largest city in Croatia. This unpredictable spread almost caused the collapse of emergency response systems. Fortunately, a greater tragedy was avoided with the composure of the responsible services and the help of the citizens. The citizens helped in extinguishing the fire and timely provided the significant amount of disaster-related information on different platforms and through social media. In this paper, we address the problem of identifying useful Volunteered Geographic Information (VGI) and georeferenced social media, for improving situation awareness while the wildfire was reaching the Croatian city of Split. Additionally, we combine social media with other external data sources (e. g. Sentinel-2 satellite images) and authoritative data (e.g. Croatian National Protection and Rescue Directorate official data and Public Fire Department of Split data) to establish the geographical relations between the wildfire phenomena and social media messages. In this manner, we seek to leverage the existing knowledge and data about the spatiotemporal characteristics of the Split wildfire in order to improve the identification of useful information from georeferenced social media with other integrated data sources that can be valuable for improving situation awareness in wildfire events.</p>

The Impact

With the intercultural exchanges between different countries becoming more and more frequent, the degree of cultural exchanges is gradually deepening, which brings more and more cultural security problems. As an important part of national security, cultural security is closely related to national interests. This article takes Chinese college students and social workers who just graduated as research objects, takes online comments on “hip-hop” culture and “funeral culture” as research objects, and uses literature research and empirical research methods to analyze social media comments and study the cultural security situation in China. It is concluded that online comments have a significant impact on cultural identity and cultural security, and negative online comments have a greater impact on both than positive online comments. In addition, cultural identity has a significant impact on cultural security. At the same time, the impact of cultural identity on online comments and cultural security is partly mediated. The results of this study will help to provide reference and guidance for the maintenance of cultural security.

This paper presents a case study of microblogging during the Norway attacks on 22 July, 2011, during which a single person first detonated a bomb in Oslo, killing eight people, and then shot 69 young people on the island of Utøya. It proposes a novel way of conceptualizing the public contribution to mobilization of resources through microblogging, particularly tweeting, as a form of ‘peripheral response’. By examining the distributed efforts of responding to the crisis in relation to emergent forms of agile and dialogic emergency response, the paper also revisits the concept of situation awareness and reflects upon the dynamic and constantly changing environment that social media and crises inhabit together.

Method Approach

This chapter presents a usability study of a prototype tool intended to support information gathering during crisis situations, thus helping professional key communicators monitor social media content from several media outlets in the same workspace. The main aim of the study is to investigate how situation awareness can be optimized for key communicators during emergencies. It does so by taking a mixed method approach on usability testing and by combining emotional responses and cognitive processes to better understand how the user perceives the tool. The study contributes to the field by illustrating the importance of designing for good situation awareness in services/platforms intended for crisis communication. A key conclusion is that the use of human-computer interaction (HCI) and usability studies are central for improving digital services in emergencies. High-stress contexts require rapid decision-making and leave no room for improvisation and perception. Therefore, comprehending digital solutions correctly is crucial for overall situation awareness.

Media Data

Social media data have been used to improve geographic situation awareness in the past decade. Although they have free and openly availability advantages, only a small proportion is related to situation awareness, and reliability or trustworthiness is a challenge. A credibility framework is proposed for Twitter data in the context of disaster situation awareness. The framework is derived from crowdsourcing, which states that errors propagated in volunteered information decrease as the number of contributors increases. In the proposed framework, credibility is hierarchically assessed on two tweet levels. The framework was tested using Hurricane Harvey Twitter data, in which situation awareness related tweets were extracted using a set of predefined keywords including power, shelter, damage, casualty, and flood. For each tweet, text messages and associated URLs were integrated to enhance the information completeness. Events were identified by aggregating tweets based on their topics and spatiotemporal characteristics. Credibility for events was calculated and analyzed against the spatial, temporal, and social impacting scales. This framework has the potential to calculate the evolving credibility in real time, providing users insight on the most important and trustworthy events.
