Since February 1995, he is with the German Research Center for Artificial
Intelligence (DFKI GmbH
) in Kaiserslautern. In the DFKI
Intelligent Engineering Systems
department, he worked on knowledge representation (description logics,
constraints) and knowledge evolution (theory revision, data mining) issues
in the areas of technical configuration, production planning, and knowledge-based
Since 1996, he is a member of the DFKI
Knowledge Management department
. As a researcher in the
(Knowledge Management for Learning Organizations) and as project leader
of the DFKI part of the European (ESPRIT)
(Knowledge Management with Intranet technologies), he investigated organizational,
methodological, and technological issues for building Organizational Memories.
Special emphasis is laid upon the integration of collaboration and coordination
technologies (groupware, workflow), document management, and formal knowledge
processing (ontologies and metadata for conceptual information retrieval).
Since July 2000, he is the Project Director of the European R&D project
(Delivery of Context-Sensitive Organizational Knowledge).
Since he is six years old, he practices as a dilettant :-) with more or
less success several kinds of sports (like apparatus gymnastics, jogging,
squash, and tennis) and does some honorary work for the gymnastic club in
the village he stems from, the Turnverein
Bierbach 1905 e.V.
Currently he was a member of the team organizing the German National Championships
in Short Distance Orienteering in 2002 (

Knowledge Representation for Expert Systems and Corporate Memories
Maintenance of Declarative Knowledge: My main work in the
DFKI project VEGA was to investigate formally well-founded methods for the
evolution of declarative knowledge bases. This can be seen as a cooperation
of KB exploration and KB validation algorithms. The field of Theory Refinement
seems to be closely related. (1995-97).
Configuration: Together with Holger Wache and Harald Meyer
auf'm Hofe, we investigate use of logic-based knowledge-representation and
inference to tackle the AI problem class configuration. There remains a lot
of work until we have well-founded and efficient methods for real real-world
Constraints: I initiated and co-organized the 1. DFKI Workshop
on Constraint-Based Problem Solving (1996). More about the topic can be
found under the address of
Harald Meyer auf'm Hofe
Description Logics: As a student, I worked on tailoring logic-based
knowledge representation approaches to real-world technical domains (DFKI
projects ARC-TEC and TOOCON). This resulted in the hybrid knowledge compilation
laboratory COLAB. Especially, I implemented parts of the TAXON terminological
logic system (1990-94).
Machine Learning and Data Mining
Data Mining Algorithms: I supervised a student work (Karsten
Schnittker) investigating improvements of the relational learning algorithm
Inductive Logic Programming: Together with
Dr. Knut Hinkelmann
I supervised a diploma thesis (Elisabeth Daub) on performance improvements
for Inductive Logic Programming (1995/96).
Genetic Algorithms: I did some work on the GA-based Nearest-Neighbor-Classifier
GIGA which was invented and implemented by
from the University of Kaiserslautern (1995/96).
Hydrology: in an informal cooperation with the University
of Kaiserslautern, Fachgebiet Wasserwirtschaft (Water Resource Management),
we investigate the use of fuzzy-constraints and heuristic search for improving
infiltration models (1996/97).
Engineering of Computer Based Systems (ECBS): in a cooperation
with the University of Karlsruhe,
Institut für Mikrorechner und Automation
(IMA), we investigate the use of knowledge representation and knowledge
evolution methods for ECBS (1995/96).
