Abstract:With critical business information distributed across both structured
and unstructured data sources, enterprises are increasingly realizing
the importance of seamlessly integrating relevant structured and
unstructured data. Existing information integration solutions
typically address this issue by providing a single point of access
for both structured and unstructured data sources. This is not
enough, since the application still needs to formulate the SQL logic
to retrieve the needed structured data on one hand, and identify a
set of keywords to retrieve the related unstructured data on the
other. This is a limitation since (a) the same information need needs
to be formulated using two disparate paradigms, which is redundant
effort, and (b) in many cases, it is hard (even impossible) for the
application to identify appropriate keywords needed as above to
retrieve related unstructured data. The SCORE project addresses this
limitation by following a novel approach to information integration.
In this approach, the application specifies its information needs
using only a SQL query on the structured data, and the system
automatically "translates" this query into a set of keywords that can
be used to retrieve relevant unstructured data. In this paper, we
describe the techniques used in SCORE for this query translation, and
also present an experimental study that illustrates the effectiveness
of these techniques
