MKLab participates in the just launched hackAIR project

The hackAIR project was launched on January 2016 in Thessaloniki by a consortium of six partners of five European countries. hackAIR will develop an open technology toolkit for citizens€™ observatories on air quality. This toolkit aims to complement official air quality data with a number of community-driven data sources, including an easy-to-build open hardware sensor module that transmits regular air quality measurements via Bluetooth, air quality information derived from mobile phone pictures of the sky and social media, as well as a low-tech measuring setup involving vacuum cleaners and coffee filters.

Dem@Care Context Descriptor Pattern

The Dem@Care Context Descriptor ontology has been integrated in the Linked Open Vocabularies (LOV) dataset, enabling its sharing and reuse by other datasets in the Linked Data Cloud (a human-readable description of the vocabulary is available here). The ontology has been developed in the framework of the Dem@Care project and provides the vocabulary to annotate complex (high-level) activity classes with low-level observations for complex activity recognition. For more details, please refer to the relevant paper: G.

MKLab successfully organized the 10th European Summer School on Information Retrieval

The European Summer School in Information Retrieval (ESSIR) is a scientific event founded in 1990, which has given rise to a series of Summer Schools held on a regular basis to provide high quality teaching of Information Retrieval (IR) and advanced IR topics to an audience of researchers and research students. ESSIR is typically a week-long event consisting of guest lectures and seminars from invited lecturers who are recognized experts in the field.

Successful participation of CERTH-ITI in the interactive Surveillance Event Detection task of TRECVID 2015

CERTH-ITI participated to the interactive Surveillance Event Detection (SED) task of TRECVID 2015 with the video retrieval engine VERGE. VERGE results achieved the second place, among the submissions made by all institutions participating to TRECVID 2015 SED task (runs from 4 different institutions searching for 7 events: cell to ear, embrace, object put, people meet, people split up, poining) with interactive systems. The latest version of VERGE integrates advanced retrieval functionalities including visual similarity search, object-based retrieval and visual concept-based search in a user friendly interface.

MKLab successfully participates in MediaEval 2015

MKLab had a very successful participation in the 2015 edition of the MediaEval benchmarking activity that took place in Wurzen, Germany on 14-15 September. The team participated in four tasks: Placing, Diverse Social Image Retrieval, Verifying Multimedia Use, and Synchronization of Multi-User Event Media, with the last two tasks being co-organized by members of the lab. The team achieved impressive results in two of the tasks, namely the Placing Task, in which it achieved the best performance, being the only participation to outperform the system provided by the organizers, and in the Diverse Social Image Retrieval task, where the team achieved the best performance in the single-topic queries, and the second best performance overall.

MKLab participates in the Hardware Grant Program of NVIDIA

MKLab is happy to announce that we received support from the Hardware Grant Program of the NVIDIA Corporation to continue our research (Zampoglou et al., 2015) on the field of multimedia forensics, which is currently carried out in the context of the REVEAL EC co-funded project. In particular, we are going to explore the potential of employing Deep Learning approaches on the problem of image splicing detection.    M. Zampoglou, S.

H2020 - MAMEM's website is launched

The H2020 project MAMEM, started in May 1st, 2015, aims at integrating people with disabilities back into society by endowing them with the critical skill of managing and authoring multimedia content using novel and more natural interface channels. These channels will be controlled by eye-movements and mental commands, significantly increasing the potential for communication and exchange in leisure and non-leisure context. MAMEM's website adopts a rather unconventional design with the intention to become the project's "

Corporate Social Responsibility Metrics Retrieval tool

We are making available a new demo for the extraction of Corporate Responsibility Metrics in companies. The tool, which has been developed in the context of the Wikirate project, exploits information extraction techniques to fetch articles and metrics from relevant websites concerning the corporate sustainability practices of thousands of companies. As many as 17,000 articles have been retrieved for 7,000 companies in the Human Rights domain, while 57,000 metrics were extracted regarding their Corporate Responsibility behaviour.
