summaryLanguage Models have brought major breakthroughs in naturallanguage processing. Notwithstanding this success, I will show that certain applications still need symbolic representations. I will then show how different methods (language models and others) can be harnessed to build such symbolic representations in the form of knowledge bases. I will highlight several challenges in this endeavor, from finding good embeddings to improving entity linking and dealing with fallacies and textual entailment. I will also discuss how language models can be evaluated along several dimensions. Finally, I will talk about the knowledge bases themselves, most notably our YAGO project. I will present our work on detecting and alleviating incompleteness in knowledge bases, on querying the data, on using the data for the digital humanities, and on reasoning on beliefs.
