Too Much Information - Can AI Cope with Modern Knowledge Graphs?

Knowledge graphs play an important role in artificial intelligence (AI) applications - especially in personal assistants, question answering, and semantic search - and public knowledge bases like Wiki-data are widely used in industry and research. However, modern AI includes many different techniques, including machine learning, data mining, natural language processing, which are often not able to use knowledge graphs in their full size and complexity. Feature engineering, sampling, and simplification are needed, and commonly achieved with custom preprocessing code. In this position paper, we argue that a more principled integrated approach to this task is possible using declarative methods from knowledge representation and reasoning. In particular, we suggest that modern rule-based systems are a promising platform for computing customised views on knowledge graphs, and for integrating the results of other AI methods back into the overall knowledge model.
