The Connectivity of Multi-Modal Knowledge Bases

Today, large knowledge bases are developed collaboratively and in an incremental manner. Often the engineering starts with the collection and organization of informal elements, that are subsequently refined into explicit knowledge. Due to the size of knowledge bases and the collaborative setting, the analysis of the current development progress becomes an important issue. The results of that analysis usually steer the further development direction and efforts. In this paper, we introduce a graph-based representation of general knowledge bases, containing formal and informal knowledge. We use this representation to define general and tailored connectivity measures for knowledge bases. We briefly report on the application of these measures in an industrial case study.
