With dedicated sessions on specific topics led by specialists from the BDE project and the Security domain, the workshop aimed to:
- Identify current and future challenges for Big data and data management in the “Secure Societies” societal challenge;
- Build a Security community involving relevant entities through the collection of user requirements and Big Data implementation strategies;
- Show real world examples and use cases;
- Highlight the current state of the BDE project and the pilot case for the Security domain;
- Support the design and realization of the necessary ICT infrastructure on which the deployment and use of the BigDataEurope platform will be based.
The workshop was a success with 45 people coming from the European Commission (DG CNECT, DG HOME, DG GROW, DG RTD), JRC, EDA, EUROPOL, Frontex, ESA, DLR, CDTI, ASD-EUROSPACE, EARSC and a number of other entities and private companies covering the domains of Space and Security, Fight against Crime and Cybersecurity.
The workshop was divided in two main sessions: the morning session consisted of an introductory part followed by invited talks while the afternoon session consisted of two interactive discussions. The introductory talks aimed to offer an overview of Big Data challenges and opportunities in Europe, focusing on the societal challenge “Secure Societies”, while the invited talks intended to cover the main areas of the Secure Societies challenge: Space and Security, Fight against Crime and Cybersecurity. The first interactive discussion showed an overview of the technical challenges and issues for the platform development and pilot implementation, in order to discuss with the audience the architecture to adopt and the advance analytics tools to use. The second interactive discussion aimed at presenting some on-going projects and initiatives in order to collect more ideas for the development of the Security pilot. The session was also dedicated to collect requirements from the audience in addition to those highlighted during the day.
The workshop represented the opportunity to present the Security pilot. The pilot will cover all the challenges of Big Data: volume (wide satellite images), variety (heterogeneous sources of data, as images and text from news and social media), velocity (fast-paced social data – news stream), veracity (cross-verification of the sources) and value (adding useful information). Apart from the established Big Data tools in the frame of the lambda architecture, specific tools for image processing, text mining, geo-data storage & access as well as a GUI will be considered. The first workflow of the pilot is defined as change detection workflow and it is based on remote sensing data: existing tools for satellite images selection, download and processing (such as co-registration and change detection) will be integrated into the BDE platform, scaling their operations to large volumes of data by transforming them into a parallel procedure. If a change is detected using satellite images, the social sensing part of the workflow will be activated in order to add information to the satellite information and to verify the event. The second workflow of the pilot is called event detection workflow and it is based on social sensing data: it extracts information from news and social media, whose outcomes activate the change detection tool, focusing its processing on a specific area.
