Current Work and Projects | |
 | I am leading the project NEXUS that aims at supporting the adaptive information exchange in collaborative settings, with a focus on aggregating and integrating a variety of data sources from the social and semantic web. NEXUS is funded by the Bundesministerium für Bildung und Forschung (Federal Ministry of Education and Research) from 12/2011 until 11/2014. |
 | The aim of the project RADAR (Resource Annotation and Delivery for Mobile Augmented Reality Services) was the development of an infrastructure to contribute, organize and annotate multimedia resources that can be used within mobile augmented reality services. By focusing on design and usability, the use of open standards for the integration of all established types of multimedia content, reusability of contents, and integrability of services in other contexts, we established an open ecosystem that allows to make the abundance of location-dependent digital resources available in mobile augmented reality services. Besides adapters for existing services like Aloqa, Junaio, Layar or Wikitude, a new personalized and location-based mobile augmented reality service has also been developed. RADAR was sponsored by the Stiftung Rheinland-Pfalz für Innovation from 03/2010 until 02/2011, and I was the project initiator and leader. |
 | I am (now technical) leader of mindpool, DFKI's internal project aiming to offer a social media suite for all DFKI employees (in Berlin, Bremen, Kaiserslautern and Saarbrücken). Mindpool consists of two components: mindpool hints is a microblogging tool based on the Open Source microblogging service status.net, and mindpool treasures is a social resource sharing platform based on ALOE. Several strategies to encourage users to participate were developed to foster the creation of a sustainable community. Due to organizational reasons, I limited my responsibilities for mindpool to the underlying infrastructure and technologies after its launch. Currently, I'm resposible for enhancing Mindpool with the component MindMedia that allows for organizing visits and media contents. |
 | The goal of iGreen is to realize a distributed network of location-based services and knowledge sources (i.e. enabling the integration of decentralized, highly heterogeneous public/private information sources) relevant for the domain of agriculture. iGreen also aims to provide a framework for the development of mobile decision support systems. Within iGreen, I'm responsible for the planned expert network which will be based on the ALOE system. iGreen is sponsored by the German Federal Ministry of Education and Research BMBF from 2009 to 2012. |
 | Within the Cluster of Excellency "Center for Mathematical and Computational Modelling" (CMCM), I'm responsible for DFKI's contributions to the development of a Web of Models. The focus in our sub-project WeWoM is on using social media to build up a sustainable community, and to enable a social Web of Models. Therefore, ALOE will be used as a basis. CMCM started in 2008 and is funded by the Government of Rhineland-Palatinate. |
 | The objective of the European Project MACE (Metadata for Architectural Contents in Europe) is to create a common infrastructure for enriching and retrieving educational contents about architecture in Europe. It is co-funded by the EU eContentPlus program from 09/2006 until 10/2009. DFKI is partner in the consortium, and I am coordinating our contributions. |
Previous Projects | |
 | I was leader of the project C-LINK (Conference Link). The aim of C-LINK was the development of a web based tool to support conference attendees. With C-LINK, users can share papers and presentations, generate individual conference schedules, get personalized recommendations to find interesting events and attendees, etc. C-LINK is based on the social resource sharing platform ALOE and serves as a showcase for DFKI technologies (e.g., the information retrieval system DynaQ). It was used during the KI 2008 (the Annual German Conference on Artificial Intelligence) in Kaiserslautern and the ICDAR 2009 (the International Conference on Document Analysis and Recognition) in Barcelona. C-LINK was an internal DFKI project funded from 03/2008 until 12/2008. |
 | I was also leader of the project CoMet (Collaborative Sharing of Resources and Metadata), where we developed an open platform to share metadata about arbitrary types of digital resources. Access to the system was possible via a web interface with a lot of Web2.0 functionalities, and a SOAP API allowed the integration into different contexts and applications. CoMet was sponsored by the Stiftung Rheinland-Pfalz für Innovation from 04/2007 until 03/2008. |
 | Topics of the project AIM (Adaptive, Interactive, and Multi-Perspective Document Management & Knowledge Navigation) were the design and implementation of a framework for the support of adaptive, interactive and multiperspective knowledge management as well as the application of this framework to different domains. AIM was part of the DASMOD (Dependable Adaptive Systems and Mathematical Modeling) Cluster of Excellence at the University of Kaiserslautern (funded by the Government of Rhineland-Palatinate). Participating research groups were the DFKI "Knowledge Management" group and the Fraunhofer ITWM "Adaptive Systems" section. I'm responsible for DFKI's part... [Wiki] |
 | At the University of Kaiserslautern, I was part of the Knowledge-Based Systems Group staff from 2003 to 2006, contact person for several lectures and supervising several works of students. [teaching activities] |
 | The aim of the project BibTutor (sponsored by the German Federal Ministry of Education and Research BMBF) was to develop an electronic tutor system for research in information sources. The focus of my work in this project was on metadata (especially for information modules), user modeling and adaptivity. |
 | CityGuide Mobile is an interactive and innovative navigation system for pedestrians requiring just a standard mobile phone or handheld computer. The project was initiated by DFKI and won the multimedia contest 2003/04 of the federal state of Rhineland-Palatinate "Media in Motion". The system was developed in the face of the FIFA World Cup 2006™ in a consortium together with the City of Kaiserslautern and Webnologic Internet Systems. DFKI was consortium leader, and I was the project director. |
 | I was also project leader for DFKI's 2nd activity in conjunction with the FIFA World Cup 2006™: For the City of Kaiserslautern, DFKI was presenting "AIBO Soccer" events in the face of the FIFA World Cup 2006™. Amongst others, the AIBOs played in Berlin, New York and Yokohama! AIBOs are ordinary Sony Roboter dogs, and they are equipped with the software of the RoboCup World Champion 2004 and 2005: The German Team. Special thanks to the Center for Computing Technologies (TZI) in Bremen for enabling these events by support and training! |
 | DaMiT (Data Mining Tutor) was research and development project sponsored by the German Federal Ministry for Education and Research (BMBF) from 2001 to 2003. DaMiT abbreviates "Data Mining Tutor" and is an Internet-based Intelligent Tutoring System for the domain of knowledge discovery and data mining. In DaMiT, I was responsible for the authoring tool and the conception of the Learning Object architecture and metadata. |
