Interview about our participation in the XR4DRAMA project

XR4DRAMA, a project coordinated by our lab, interviewed the Project Technical Coordinator Sotiris Diplaris presenting our project team, our expertise and involvement in XR4DRAMA, as well as the expected challenges and outcomes of the project. XR4DRAMA utilises several XR technologies towards improving significant parts of our lives that depend on situation awareness and decision making. Read full inteview here:

The ultimate platform to handle extreme weather events! The European Commission has officially labelled Η2020 beAWARE (coordinated by MKLab) as a “success story”!

As stated in the EC article, the beAWARE platform is much more than a crisis management platform to help authorities, first responders and citizens. It should rather be seen as a combination of relevant state-of-the-art technologies spread across different components and applications. It encompasses a protection and rescue service, it can be used for risk assessment (including scenario building), and it supports the core functions of call centres (public safety answering point or PSAP).

Best Paper Award at ICCSA 2020

Bridging the gap between Copernicus data providers and end users through Artificial Intelligence solutions

MKLab of ITI-CERTH is delighted to participate in the newly launched, EU-funded H2020 project CALLISTO - “Copernicus Artificial Intelligence (AI) Services and data fusion with other distributed data sources and processing at the edge to support DIAS and HPC infrastructures”. MKLab has a significant role in CALLISTO, being the scientific and technical coordinator, as well as leading one Work Package and several tasks, including social media data collection, change detection on satellite and UAV images, data fusion, and information retrieval.

Kicking off i4Q - New project to pave the way towards Industry 4.0

MKLab coordinates the H2020 project i4Q on Industrial Data Services for Quality Control in Smart Manufacturing. The project had its Kick off Meeting on Tue. 19/01/2021 - Wed. 20/01/2021 and it aims at providing the industry with a complete solution that will consist of sustainable IoT-based Reliable Industrial Data Services (RIDS) which will be able to manage huge amounts of industrial data. This data will come from cost-effective, smart, and small-size interconnected factory devices and will be supported by i4Q throughout their complete flow, meaning from data collection to data analysis, simulation and prediction.

MKLab presents the Oil Spill Detection Dataset to the research community

(a) Sample of a SAR image and (b) Corresponding annotated image. Cyan color corresponds to oil spills, red to look-alikes, brown to ships, green to land and black is for sea surface. Aiming to enhance the research activity in the field of oil spill detection, the Multimedia Knowledge and Social Media Analytics Laboratory (MKLab) has developed the Oil Spill Detection Dataset, a dataset containing Synthetic Aperture Radar (SAR) images depicting oil spills and other relevant instances.

Resting-State High-Density EEG using EGI GES 300 with 256 Channels of Healthy Elders, People with Subjective and Mild Cognitive Impairment and Alzheimer's Disease

This repository contains Matlab files including 4 samples of 15 minutes resting-state EEG recording for Alzheimer's Disease (AD), Mild Cognitive Impairment (MCI), Subjective Cognitive Decline (SCD), and Healthy Controls (HC) using the HD-EEG EGI 300 Geodesic EEG system (GES 300, CERTH-ITI, Thessaloniki, Greece) with a 256-channel HydroCel Geodesic Sensor Net (HCGSN). In total 230 participants have been recruited from the memory and dementia clinic of the Greek Association of Alzheimer's Disease and Related Disorders (GAADRD) and the 1st Department of Neurology, U.

Joint EOPEN-BETTER exercise in the H2020 BETTER Project Hackathon

A joint exercise will be supported by Fraunhofer IAIS (BETTER project) and MKLab ITI-CERTH (EOPEN project) in the final BETTER Hackathon. This step-by-step exercise will involve the conversion of Tweets to RDF for ingestion by SANSA for semantic geo-clustering and visualization. We invite students, software developers, data scientists, EO-developers, or anyone with interest in EO and semantic interoperability topics to participate. Date & Time 29 October 1.30pm – 5.30pm CET

Flood-Related Multimedia Task at MediaEval 2020

MKLab in cooperation with the Alto Adriatico Water Authority (AAWA) is organizing the Flood-related Multimedia task at the MediaEval Multimedia Evaluation benchmark, an initiative that is dedicated to evaluating new algorithms for multimedia access and retrieval. The task requires participants to build an information retrieval system or a classifier that is able to distinguish whether or not a tweet is relevant to a flooding event in an area of interest, in order to support flood disaster management.

Visualisation Tool for monitoring Italian tweets concerning COVID19

The Multimedia Knowledge and Social Media Analytics Laboratory (MKLab) of the Centre for Research & Technology Hellas (CERTH) participates and contributes actively in the Security Research Rapid Response Platform ( and the efforts to combat COVID19 by developing a web-based application to monitor, analyse and visualise social media posts related to the Coronavirus pandemic. The Social Media Visualisation Tool ( collects tweets with the hashtags #covid19Italy and #covid19italia, focusing on the region of Italy.
