Abstract
In the Linked Data field, data publishers frequently materialize linksets between two datasets using link discovery tools. However, when the datasets are continually updated, a materialized linkset must also be updated since the links may no longer meet the linkage rules. To help solve this problem, this paper presents an approach for maintaining linksets, which treats linksets as materialized views, is based on changesets and adopts an incremental strategy. The paper formalizes the materialized linkset maintenance problem based on changesets and indicates that our approach correctly maintains materialized linksets views. Finally, it suggests an architecture and describes an implementation and experiments to validate the proposed approach.
