Answering Keyword Queries on XML Using Materialized Views
Ziyang Liu, Yi Chen · 2008
Answering queries using materialized views has been well studied in the context of structured queries and has shown significant performance benefits. Despite the popularity of keyword search over XML data, it is an open problem whether materialized views can be leveraged for query evaluation. In this paper, we investigate this problem and present techniques for answering keyword queries using a minimal number of materialized views. Experimental evaluation demonstrates the efficiency of the proposed techniques.
