Knowledge-Based Systems E192-03

A Research Unit of The Institute of Logic and Computation

Our major research topic are programming languages for knowledge, including how to represent knowledge in an understandable and intuitive way, and how to process it in an inferential manner, by manipulating chunks of knowledge in symbolic form.

About

The goal of our research is to gain insight into these questions and to obtain fundamental results, to develop algorithms, and to build prototype implementations of tools for knowledge representation and reasoning.

To this end, we use methods from mathematics, theoretical computer science, and logic (formal analysis), engineering (algorithms and prototypes), as well as statistics and cognitive science (evaluation).

For more information, see our research area description.

The research Unit Knowledge-Based Systems is part of the Institute of Logic and Computation.
