XOFilter: A System for Filtering Heterogeneous XML Streams Based on Ontology

The problem of processing XML streaming data fits a large class of new applications and has been a hot spot recently. The XML streams on the world wide web are usually autonomous, distributed and heterogeneity. All existing methods, however, do not support filtering a collection of XML streams from heterogeneous sources. In this paper, the authors present a system called "XOFilter" to address the issues of heterogeneity in the context of XML stream processing.
