Geography colloquium series at SDSU

On 8th February, the BDEM coordinator Professor Rajendra Akerkar delivered a colloquium at the Department of Geography, San Diego State University, USA. The topic of this colloquium was “Managing Emergency Situations Using Big Data – A Perspective”. With the advent of Internet of things, social media, wearable devices, mobile phones, and planetary-scale sensing there is an ample opportunity to transform big geo-spatial data into actionable information. The talk focused on emergency management which is fundamentally a spatio-temporally distributed heterogeneous data assimilation problem for situation detection. Professor Akerkar illustrated examples from related projects in his research group and presented key challenges for managing big emergency data.

SDSU’s The Center for Information Convergence and Strategy (CICS) is one of the partners in BDEM project. The Center is active in diverse domains, such as disaster response, global security, threat reduction, business development, biomedicine, public health, and the digital humanities. It emphasizes data acquisition and analytics, social media solutions, strategic mapping, data mining, and systems integration and development. From visualization to machine learning and predictive analytics, CICS leverages information technology to evaluate current trends and develop strategies based on dynamically evolving content. 

The BDEM researchers at the ICT-DM2018 conference in Japan

Dr. Minsung Hong (Western Norway Research Institute) and Dr. Haoran Zhang (the University of Tokyo) participated in the 5th International Conference on Information and Communication Technologies for Disaster Management (ICT-DM 2018) in Sendai, Japan, in 4-7 December, 2018 to disseminate results of the BDEM project. They have presented one paper and poster at the conference.

An Integrated Crowdsourced Framework for Disaster Relief Distribution

Timothy Schempp, Haoran Zhang, Minsung Hong, Alexander Schmidt and Rajendra Akerkar

This paper outlines our ongoing efforts at building an effective disaster relief system utilizing real-time, crowdsourced responses to disaster events. This system integrates three components: social media analysis, rescue demand prediction, and relief distribution optimization. We introduce the conceptual disaster relief system, database structure, and its integrated components. Finally, a summarization of the current research challenges we expect to address in the future is provided.

Role of Semantics in Analysing and Processing of Big Emergency Data

Minsung Hong and Rajendra Akerkar

This poster paper outlines an ongoing research that aims to incorporate semantically enabled Big Data processing for emergency response . The ultimate aim is to create an integrated platform to support prediction, early alerts, transmission and routing of the emergency data, aggregated analysis of multimodal data and coordination between emergency stakeholders (e.g. first responders, the authorities, volunteers). The modelling and computing challenges associated with such platform can be organised in terms of the 5 Vs of Big Data, which provides a means to organise our research efforts in addressing Big Data challenges using semantics.

The conference also provided the opportunity to discuss upcoming research themes in data-driven emergency management with the BDEM project members in Japan, in particular, Professor Ji (National Institute of Informatics, Japan) and with other prominent international researchers who attended the conference.
