Query: CS563-QA: A Collection for Evaluating Question Answering Systems   Question Answering (QA) is a challenging topic since it requires tackling the
various difficulties of natural language understanding. Since evaluation is
important not only for identifying the strong and weak points of the various
techniques for QA, but also for facilitating the inception of new methods and
techniques, in this paper we present a collection for evaluating QA methods
over free text that we have created. Although it is a small collection, it
contains cases of increasing difficulty, therefore it has an educational value
and it can be used for rapid evaluation of QA systems.
