“…Social media already possess a high value for marketing as, according to Patino et al [30], the increasing speed of social media made it necessary for the marketing sector to change over to social media: Communication channels like TV, print media, telephone and (letter) post lost much of their meaning and the potential customers spend more and more time online. Multi channel warning systems have to take this into consideration [18].…”

A growing body of research in the area of information systems for crisis management is based on data from social media. After almost every larger disaster studies emerge with the focus on the specific use of social media. Much of this research is based on Twitter data, due to the ease of access of this (mainly public) data, compared to (more closed) data, such as Facebook or Google+. Based on the experience gained from a research project on social media in emergencies and our task to collect social media data sets for other partners, we present the design and evaluation of a graphical user interface that supports those stakeholders (such as emergency services or researchers) that are interested in creating social media datasets for further crisis management research. We do not specifically focus on the analysis of social media data. Rather we aim to support the gathering process and how actors without sophisticated technical skills can be supported to get what they want and especially need: relevant social media data. Within this article, we present a practice-oriented approach and implications for designing tools that support the collection of social media data as well as future work.

“…Another component of the proposed system is represented by the information sharing among public safety operators and/or citizens. The citizens are usually destination points of alerts and warnings as in [11,18] where emergency-related information is distributed by means of multi-channel communication links. The citizens are usually destination points of alerts and warnings as in [11,18] where emergency-related information is distributed by means of multi-channel communication links.…”

“…In [17], it is proposed an open virtual collaboration environment that facilitates collaborative work in a virtual space made by a dynamic website and 3D space for meetings. The citizens are usually destination points of alerts and warnings as in [11,18] where emergency-related information is distributed by means of multi-channel communication links. Recently, also the active citizens participation has being considered.…”

This paper proposes an efficient architecture of a smart public safety platform that involves public professional operators as well as citizens. The proposed system is compliant with the emerging paradigm of a smart city. Its main features are that of monitoring, forecasting and managing emergency situations, arising from environmental disasters or crimes. The proposed platform performs a smart and functional integration of heterogeneous components as a smart data gathering and analysis system, a novel professional communication system, wireless sensor networks and social networks. Each element acts not only as an information collector but has autonomous capabilities to cooperate with the others in order to increase the system efficiency and to reduce the need of human interactions. Finally, the paper highlights some open research issues that represent critical aspects and require additional investigations in order to further improve the performance of the proposed platform.City management, improving quality of offered services by reducing costs, introducing transparency and citizen participation. It has to give the citizens an appropriate, precise and clear information awareness about the correct use of the resources made available by the community and show the possibilities deriving from a direct involvement in civil life. Education, allowing the use of technology to increase access, improving the quality and experience, and reducing costs.Healthcare, allowing more accurate and rapid diagnosis and responses to emergency. Storage and communication platforms permit data to be stored and shared for diagnosis and research. Transportation, improving services, as traffic management in congested areas, and at the same time reducing costs. The goal is to reduce traffic congestion while encouraging the use of public transportation. Environment, improving the environmental conditions, limiting the sources of pollution, increasing the green areas, providing widespread health services, etc. Economy, promoting innovation, productivity, exportation, etc. Public safety, improving the capability of monitoring critical environments and forecasting disasters due to both natural causes or terrorist attacks. It uses real-time information to respond rapidly to emergencies and threats.Among these smart systems, this paper aims to identify an efficient architecture of a smart public safety platform. Indeed, with the huge increase of cities population density, public safety operators need to respond more quickly to emergency situations. It has made essential the need of effective and smart emergency management solutions. New and advanced systems and platforms have to be identified in order to guarantee the safety and well-being of citizens, properly protect services and critical infrastructures. Smart solutions for public safety involves to accomplish complex tasks related to the following:Monitoring and forecasting-adopting specific monitoring activities and analysis of results arising from the monitoring campaigns to prevent natural...

The origins of building early warning systems for large groups of population could be found between two world wars last century. One of the base requirements of warning systems was to build an extensive network of warning sirens. An integral part of warning technologies has been training people how to behave in cases of threat and danger. The performance of alerting infrastructure decreased dramatically after the collapse of communist regime at European countries at the beginning of nineties. It becomes increasingly difficult to bridge the ""last-mile"" between local emergency management authorities and the population in times of crises [5].The introduction of new technologies brings intense challenges to their application for the "lastmile" communication in the frame of early warning systems. However, there is no unified concept for newly conceived schemes of communication channels. The approaches of individual countries and regions to the "last-mile" communication differ from each other even dramatically [3], [4].Recently published a number of papers deal with the issue of accessibility and usability of communication channels. Klaft [5] on the example of subscription-based "Katwarn" system (multichannel alerting system, which offers the possibility to distribute alerts via SMS, e-mail, and pagers) tested reception of warning information (majority participants were people with some affiliation to emergency management). The alert message was randomly generated and sent on August 24th, 2009 at 14:09 CET. Approx. 25% of participations noticed and read the alert within ten minutes. This ratio increased to 32.4% within twenty minutes, to 47.9% within one hour. After five hours more than 35 % of participants didn't make any action (!).Another Katwarn case study observed actual user behavior on the same subscription-based system. After sending the test alert message at 9:58 a.m. to approx. 14 thousands subscribed users, the log files of the information website were analyzed to see how often the site had been accessed. Within ten minutes were identified only 6.1% of alert recipients. This number increased to 8.5% within 30 minutes and to 11.6% within two hours. After 24 hours, the ratio reached 17.4% (!).Research in Indonesia costal municipality [10] provides information about quantification of access to media by the type of media and time of the day. In the morning the main availability to get access is represented by mobile phones (63 %), TV (60 %), radio (55 %). Access to TV and radio raises during the day to 88 % (TV at the evening) and 64 % (radio). Sirens cover less than 48% of people.The role of early warning systems does not finish with the end of emergency. It is necessary to maintain communication connection even in times of crisis and in subsequent stages, i.e. recovery and resilience. Major problem remains to scientists and policies -how to effectively deliver the authorized recipient in case of emergency necessary adequate information in a timely manner, i.e. at the right time to the right place.It is evid...
