MKLab participated again this year in the annual TRECVID benchmarking activity, organized by the US National Institute for Standards and Technology (NIST). MKLab participated in four TRECVID tasks: Semantic Indexing (SIN), Event Detection in Internet Multimedia (MED), Multimedia Event Recounting (MER), and Instance Search (INS). Our results in these tasks were very good, significantly improving the results we had obtained in previous years.
Particularly for our participation in the Event Detection in Internet Multimedia (MED) task, we used a new, very fast machine learning method for big data problems, which we developed.

A tutorial on “Video Hyperlinking” was delivered at two major scientific conferences, the IEEE Int. Conf. on Image Processing (ICIP; Paris, France, Oct. 2014) and the ACM Int. Conf. on Multimedia (ACMMM; Orlando, FL, USA, Nov. 2014), by Vasileios Mezaris (CERTH) and Benoit Huet (EURECOM). The slides of the tutorial, discussing various state of the art video analysis techniques (ranging from temporal video fragmentation to high-level description of the video’s content using concept and event labels) and their use towards video hyperlink generation, are available online, in three parts:

The Dem@Care Lab Ontology for Dementia Assessement 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 for representing the experimentation protocol towards diagnostic support and assessment of Dementia in a controlled environment. The aim of the protocol is to provide a brief overview of their health status of the participants during consultation (cognition, behaviours and function), and to correlate the system (sensor) data with the data collected using typical dementia care assessment tools.
