Knowledge Extraction from C-Code

In this paper we present first ideas for extracting knowledge from C source code of control programs. The extracted knowledge is intended to be used in our smart control engine which takes a rule set and decides which rules to use based on the internal and environmental conditions. The extraction of rules is based on the control-flow graph of the supplied C program: Basically, our method extracts rules that correspond to paths to given high-level function calls. The advantage of this method is to get a first knowledge-base from available source code which makes using a smart control engine more applicable for industry. We use an industrial control program as example within the paper in order to justify the usefulness of our approach.
