Abstract.    The Deep Web has enabled the availability of a huge amount
of useful information and people have come to rely on it to fulll their
information needs in a variety of domains. We present a recent study
on the accuracy of data and the quality of Deep Web sources in two
domains where quality is important to people's lives: Stock and Flight.
We observe that, even in these domains, the quality of the data is less
than ideal, with sources providing conicting, out-of-date and incomplete
data. Sources also copy, reformat and modify data from other sources,
making it dicult to discover the truth. We describe techniques proposed
in the literature to solve these problems, evaluate their strengths on our
data, and identify directions for future work in this area.
