Résumé: Information Extraction is the task of extracting structured information (such as entities and facts) from natural language documents. It is an important step in making legal documents (such as laws or contracts) available to a computer. In this talk, I will give an overview of how far information extraction has come, what techniques it uses, and what pitfalls it still faces. I will also draw on our own works in the domain of knowledge base construction, rule mining, and the analysis of the power of neural architectures.
