Knowledge Base Construction

Course in Autumn 2016 at Télécom ParisTech
in the M2 Data & Knowledge
© 2016 Fabian M. Suchanek


In this class, we will take an overview of Information Extraction for Knowledge Base Construction. This is the process of deriving structured information (such as alive(Elvis)) from digital text (such as the sentence "Elvis is alive"). The lecture will cover named entity recognition, entity disambiguation, instance extraction, fact extraction, and ontological information extraction. We will then see how we can mine this data for correlations. We will also touch upon applications of Information Extraction, such as Google's knowledge graph and IBM's Watson question answering system, as well as academic projects such as YAGO, DBpedia, and NELL.

The grades are now available here.
