Information Extraction (TPT33 / INF393)

Course in Autumn 2016 at Télécom ParisTech
in the ATHENS program
© 2016 Fabian M. Suchanek


In this class, we will take an overview of Information Extraction techniques and the Semantic Web. Information extraction is the process of deriving structured information (such as alive(Elvis)) from digital text (such as the sentence "Elvis is alive"). The first part of this lecture will focus on factual and semantic information extraction, i.e., we will cover named entity recognition, entity disambiguation, instance extraction, fact extraction, and ontological information extraction. The Semantic Web is the little brother of the Web that aims to represent information in a machine-readable form. So, after having learned how to extract the information from text documents, we will learn how to represent it in a semantic way. We will cover the standards RDF/S, URIs, and RDFa, and recent advances in the field. We will also touch upon applications of both Information Extraction and the Semantic Web, such as Google's knowledge graph, IBM's Watson question answering system, and Facebook's Open Graph, and academic projects such as YAGO, DBpedia, and NELL.
