Abstract

Information retrieval as observed by the wider community typically involves a user entering a set of keywords and receiving a set of documents that address their information needs. Question answering does more than this. It invites the user to enter a natural language question as a query. Using the extra information in the natural language query, a question answering system returns only information specific to the user's query.

Wikipedia is an online encyclopaedia made up of user-contributed content. Wikipedia is an interesting corpus for research as it contains a large amount of open-domain information with a large amount of user-contributed classification information and a large amount of descriptive metadata in the form of multiple titles per document.

In this talk we present a system that performs question answering using data in Wikipedia. We also discuss properties of Wikipedia that make question answering using the corpus interesting.
