My current work in the STELLAR project focuses on the development of the STELLAR Science 2.0 infrastructure for the researchers in the field of Technology Enhanced Learning. My PhD take place in the context of STELLAR. The goal is to research reflection processes within mash-up personal learning environments.
Previously I worked at the KMi for the X-Media project and SocialLearn:
I developed Knowledge Lenses for the SemSearch Semantic Search Engine within the X-Media Project (FP6 European Research Project: http://www.x-media-project.org/) to enhance the possibilities of knowledge engineers.
For SocialLearn I build the ELLIMent tool supporting mentees developing their life long learning skills within a mentor relationship. ELLIMent builds upon the Effective Life Long Learning Inventory.

Multimedia and Information Systems is...
We focus on content-based information retrieval over a wide range of data spanning form unstructured text and unlabelled images over spoken documents and music to videos. This encompasses the modelling of human perception of relevance and similarity, the learning from user actions and the up-to-date presentation of information. Currently we are building a research version of an integrated multimedia information retrieval system MIR to be used as a research prototype. We aim for a system that understands the user's information need and successfully links it to the appropriate information sources, be it a report or a TV news clip. This work is guided by the vision that an automated knowledge extraction system ultimately empowers people making efficient use of information sources without the burden of filing data into specialised databases.
