Hello Mr. Ramadass,

although this functionality doesn't exist in the open source domain (at
least not to my knowledge), @mire offers duplicate detection functionality
as part of our Metadata Quality Module.
It contains an internal similarity algorithm, that can be configured to some
extend (defining which metadata fields have to be taken into account to
identify a "duplicate match"). As an administrator, you can choose to scan
your whole repository, or certain collections for duplicates. After the
module identified these duplicates, it offers an interface to merge records.
As a result, one item remains while the other handles become referrals to
the merged item. (so your links don't break).

Additional information and demonstration movies are available here:
http://atmire.com/quality.php

We do have a version of this module for 1.4.2 JSPUI, but please note that
the movies were made on a 1.5 XMLUI DSpace, and there are differences in the
user interface. The XMLUI version of the module also integrates with the
submission workflow, e.g. users get alerted after filling in a page of
metadata fields, whether their data closely resembles existing items.
The module is also integrated in our test repository, @mire
labs<http://atmire.com/labs>,
for which you can get a (free) evaluation admin account.

kindest regards,

Bram Luyten
