Call for Papers: XPS-99 Workshop Wissensmanagement
und Organisational Memory
Proceedings: ECAI-98 Workshop Building,
Maintaining, And Using Organizational Memories
Systeme für das Wissensmanagement im Unternehmen (Knowledge-Based
Systems for Enterprise Knowledge Management)
computer science and economics at the University
of Kaiserslautern and received the Diplom in 1994. After having finished
an evaluation of data
mining techniques for credit assignment at DFKI GmbH (funded by Swiss
Bank Corporation), I started working at the German Research Center for
Artificial Intelligence (DFKI GmbH)
Kaiserslautern in February 1995. In the research department for Intelligent
Engineering Systems I worked in the VEGA
project investigating machine learning and theory revision approaches for
the maintenance of knowledge-bases. Currently, I develop methods and tools
for building organisational memories in the context of the DFKI Knowledge
Management Group which is a part of the Information
Management and Document Analysis Lab.

Knowledge Representation for Expert Systems and Corporate Memories
Maintenance of Declarative Knowledge: My main work in the DFKI project
VEGA is 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. (1995/96...).
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 conditions (1996...).
Constraints: I initiated and co-organized the 1.
DFKI Workshop on Constraint-Based Problem Solving (1996). More about
the topic at the DFKI
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: Currently, I supervise a student work (Karsten
Schnittker) investigating improvements of the relational learning algorithm
by Michael Sintek
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 Matthias
Fuchs from the University of Kaiserslautern (1995/96...).
Document Analysis: in cooperation with the DFKI Department
for Document Analysis and Office Automation (Markus Junker) I investigate
the use of machine learning algorithms for text classification (1995/96...).
Data Mining Applications: Together with the University of Kaiserslautern,
Group AI and Expert Systems, I performed a 3-month study about data
mining and case-based reasoning for credit assessment at Swiss Bank
Innovative Applications of AI Technology to Real-World Problems
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
Engineering of Computer
Based Systems (ECBS): in a cooperation with the University of Karlsruhe,
für Mikrorechner und Automation (IMA), we investigate the use
of knowledge representation and knowledge evolution methods for ECBS (1995/96...).
