Content

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 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. We will also touch upon applications of both Information Extraction and the Semantic Web, such as Google's knowledge graph/vault, and IBM's Watson question answering system, as well as academic projects such as YAGO, DBpedia, and NELL.
