METHOD AND APPARATUS FOR MANAGING MULTIPLE DOCUMENT VERSIONS IN A LARGE SCALE DOCUMENT REPOSITORY

摘要

In a large scale data repository, a single logical view of multiple versions of the same data is presented. In order to determine which data versions are equivalent without comparing each pair of entries in the database, the database entries are clustered with a clustering algorithm and 5 then comparisons between entries are made only between the entries in each cluster. Once a set of entries has been determined to be equivalent, a composite master entry is constructed from those entries in the set that contain preferred metadata and the composite master entry is made available for searches and display to the user.
