Current question answering systems rely heavily
on document retrieval as a means for identifying documents that are
likely to contain an answer to a given question. This thesis examines
the usefulness of various standard and novel document retrieval
approaches in the context of question answering. More specifically, it
compares them with respect to their ability to identify documents
containing a correct answer. In addition, we investigate to what
extent the quality of a particular document retieval approach has an
impact on the overall perfomance of a specific question asnwering
system.
