Crowdtasking as defined in this paper is a new concept for managing qualified volunteers in order to obtain requested and specific information from them. This process takes place in the frame of an interactive communication process between a task manager and preselected volunteers from the crowd. Crowdtasking differs from existing crowdsourcing approaches. Crowdsourcing, a known and proven concept in many fields including crisis management can be defined as assigning tasks to a non-specified group of people. An alternative approach is to select specific volunteers qualified for specific crisis scenarios out of the crowd, depending on the crisis scenario and to communicate with them by using specifically designed user interfaces. For the development of advanced volunteer management solutions such approaches ensure obtaining highly reliable information for crisis managers without the need to analyse large amounts of unstructured data provided by an unspecific crowd. This paper sums up the current state of the art and experiences concerning the application of crowdsourcing for crisis and disaster management and – based on this background finally describes the new concept called crowdtasking for the management of volunteers.


Das RE-ACTA Projekt wurde auf der Konferenz „Information Systems for Crisis Response and Management (ISCRAM) 2014“ unter dem Titel „The RE-ACTA Approach – Resilience Enhancement by Crowdsourcing and Crowdtasking“ präsentiert.

The international Red Cross declared that the strengthening of the population’s resilience is one of the most important challenges in today’s crisis and disaster management. For instance, the Austrian crisis and disaster management heavily relies on a large volunteer community. However, the enduring and formal membership in voluntary crisis management organizations is at odds with the current dynamics of people’s urban lifestyles. Hence, the crisis management organizations relying on the volunteers, such as the Red Cross and other Humanitarian Institutions, as well as the local or regional Emergency Services (i.e. police, fire brigade), need to find new ways of loosely binding volunteers to their organization in order to continue of being a significant and powerful part of Austria’s crisis and disaster management strategy.

The Austrian National Research Project RE-ACTA (Resilience Enhancement by Advanced Communication for Team Austria) shall address this challenge through definition and testing of new processes and workflows for volunteer coordination relying on loosely connected volunteers communicating (mainly) through mobile new media devices (e.g. smartphones). New processes shall be defined in cooperation with and tested by the Red Cross and Team Austria. The process design will assesses all necessary user requirements as well as the applicability of a crowd tasking tool in terms of legal aspects with special emphasis on liability and privacy. Another important point which will be covered is the aspect to investigate the acceptance of the tool and how the user community approves the appliance.

Social Media plays an increasing and vital role in the analytic process flow as it is an important part in our society. Improved methods and applications to monitor Social Media can provide invaluable information about incidents in general and the information which is made available through Social Media, existing and newly developed gadgets (e.g. RE-ACTA crowdsourcing/crowdtasking application tool) can make a huge difference in imminent crisis and disaster situations, and significantly lower the adverse effects to citizens and their property.

In order definite new workflows for volunteer coordination and developing a dedicated application to support these workflows, RE-ACTA will therefore develop an analytic engine capable of deriving the information from existing Social Media and enabling the crisis managers to use this information in their work. The advantage of this approach is the increased awareness of the real time crisis developments based on spontaneous input from a large number of persons. There is a need to assess the data in terms of relevance and credibility. This will be addressed by Ubicity, a new tool for data-driven applications based on the ideas of ENVIROFI. The tool is capable of analysing large amounts of unstructured and semi-structured geographic and temporal referenced data from multiple domains in near real time. The additional information, which is not available in conventional crisis management solutions shall allow help to optimize the crowd tasking processes solutions in all the phases of the disaster-management cycle, not only in the emergency phase but also during prevention and preparedness to assess the wider effects of the crisis management activities in the near real time.

The aim is to develop and implement a newly designed process for decision making and crowd tasking on the basis of the “Concept Development & Experimentation” paradigm and to foster the resilience of the public while at the same time relieving emergency and humanitarian organizations from an uncoordinated influx of information or spontaneous volunteers. The RE-ACTA approach and its software developed will help to use a large amount of information of unstructured data that are omitted due to the design of the communication process and to ensure a higher standard, readiness and response to use a future system in Crisis and Disaster Management.

In 2012, the international Red Cross declared an urgent need to strengthen the population´s resilience regarding the most important challenges in today´s crisis and disaster management. This is also evident for Austria when looking at recent occurrences of flooding in 2013. That mentioned, in the light of resilience, to be preventive and prepared, the Austrian crisis and disaster management heavily relies on a large volunteer community. While organized volunteers are educated and are contributing to the activities of the Red Cross on a regular basis, the idea of crowd tasking is addressing those spontaneous volunteers, who are not bound closely to the organization but are willing to contribute spontaneously, when their neighbourhood is affected directly by a crisis situation.

Ruggenthaler, C.  (2015), „Expanding NoSQL Technologies to Mobile Devices“ IDC Datahub, Wien


This talk will discuss the hands-on experience in building an innovative approach to establish communication channels between server-side NoSQL environments and numerous mobile device applications with added offline features. Thereby, the power of NoSQL technologies like dynamic scaling, asynchronous replication and flexible data conflict resolution will be leveraged. As data copies are spread over several mobile devices and server-side nodes, highly scalable and fault-tolerant concepts have to be used to guarantee service availability and still maintaining consistent authentication and authorization mechanisms. Moreover, data updates need to be distributed across all participating nodes by ensuring privacy and data governance aspects on each individual mobile device. The talk will close with lessons learned during the implementation and evaluation phases.

Volunteers play an increasingly important role during disaster relief activities. In addition to pre-organised, well-trained volunteers, spontaneous volunteers appear at the scene. They are organising themselves rapidly, typically via social media. However, spontaneous volunteers are not managed within the command chains of the responder organisations. They may be seen as an unexploited additional resource, provided they are adequately guided and managed. This paper describes a new concept for the management of pre-registered spontaneous volunteers called “crowd tasking”, developed by the authors and their organisations within the multi-disciplinary research project RE-ACTA. The concept was validated during a field exercise involving 20 volunteers. The paper provides a brief classification of volunteers, it explains the RE-ACTA operational concept of crowd tasking, associated requirements, design principles, system architecture and implementation aspects of the proof of concept which was used for a practical validation during a field exercise.

In this paper, we present two initiatives for volunteer management that are currently being conducted in Austria. By comparing them, we see a shift towards the use of Information and Communication Technology (ICT), which brings with it issues concerning the segregation of certain segments of the population. These, we wish to bring to the reader’s attention and discuss their implications for the use of ICT in disaster situations.
