Abstract
Keywords are suitable for query XML streams without schema information. In current forms of keywords search on XML streams, rank functions do not always represent users’ intentions. This paper addresses this problem in another aspect. In this paper, the skyline top-K keyword queries, a novel kind of keyword queries on XML streams, are presented. For such queries, skyline is used to choose results on XML streams without considering the complicated factors influencing the relevance to queries. With skyline query processing techniques, algorithms are presented to process skyline top-K keyword queries on XML streams efficiently. Extensive experiments are performed to verify the effectiveness and efficiency of the algorithms presented.
