Automatic Question Answering (QA) has received researchers’ attention over the last decade. It aims to find a short answer string which exactly addresses the users' questions rather than overwhelm them with a large number of retrieved documents, which they must sort through to find the desired answer.

This goal is usually achieved using a combination of different techniques, including

  • information retrieval
  • information extraction
  • natural language processing
  • opinion mining.

In this seminar we will cover the most important components and techniques that are required for building a question answering system. In addition, the students will build a QA system that can answer questions from "Who wants to be a millionaire?".

More information can be found in the cource webpage at information systems research group.


  • basic knowledge on information retrieval and machine learning
