Basic Research
Prof. Rettinger's research is concerned with the machine learning of expressive knowledge representations, specifically from natural language in digital media (text and image) and from knowledge bases. The goal is to build representation that are accessible to both, humans and computers while allowing expressive and explainable analysis and inference. To achieve that he develops methods that combine Machine Learning, specifically Deep Learning and Language Models, with Symbolic Knowledge Representation, specifically Knowledge Graphs and Semantic Technologies. Prof. Rettinger publishes in a wide range of research areas, like machine learning, natural language understanding and knowledge representation.
