Managing Heterogeneity by Synthesizing Composite Data

The long-standing challenge in database management, information retrieval systems are Entity resolution (ER), the problem of extracting, matching and resolving entity mentions in structured and unstructured data. Getting the data in unambiguous form when fetched from integrated heterogeneous databases had become an important task when heterogeneous databases come into picture. In order to retrieve information from these database and to avoid the retrieval of multiple ambiguous information with same citation and algorithms have been proposed. The input to the algorithm is a query output, whereas the algorithm will return only feasible data required in the query.
