Objectives

In this course, students will learn the basics of semantic information extraction, i.e. the art and science of extracting facts from natural language documents. This includes algorithms for extraction from the Web, as well as the essentials of natural language processing and knowledge representation. We will also touch upon the Semantic Web. The goal is to understand the technology behind today's large knowledge bases such as Google's Knowledge Graph, NELL, DBpedia, and YAGO.

Programme to be followed

The course will consist of lectures and practical exercises (labs). The lectures will be interactive, with small quizzes to check the understanding of the topics. The course will cover:

  • Knowledge representation (RDF, RDFS, OWL)
  • Named Entity Recognition (Regular Expressions, Tries)
  • Named Entity Annotation (Rule-based and statistical)
  • Design of extraction algorithms and evaluation
  • Disambiguation (context-based, coherence-based)
  • Instance Extraction (Hearst extraction, set expansion, iteration)
  • Fact extraction from structured sources (Wrapper induction, extraction from Wikipedia)
  • Fact extraction from text (DIPRE algorithm, POS annotation)
  • Dependency Grammars
  • Extraction by reasoning
Prerequisites

·      Basics of Predicate Logic

·      Basics of Probability Theory

·      Very good programming skills in Java, in particular data structures and Input/Output
