Maria Vargas-Vera, Enrico Motta, and John Domingue

The use of the web has become popular and also the need of services that could exploit the vast amount of information in it. Therefore, there is a need for automated question answering systems. These kind of systems should allow users to ask questions in everyday language and receive an answer quickly and with a context which allows the user to validate the answer. Current search engines can return ranked list of documents but they do not deliver answers to users.
