XML-based meta-retrieval of networked data sources

The XML-based meta-retrieval described in this paper is an integrated retrieval over multiple academic data sources on the premise that each data source has one web interface visible in the Internet environment. The goal of this model is to present an integrated retrieval interface in the Internet, to offer transparent accessing by formulating new queries suitable for heterogeneous data sources based on three adaptation rules, and to return the consolidated data results retrieved from multiple data sources. Technologies like eXtensible Markup Language(XML) and eXtensible Stylesheet Language Family(XSL) are used to facilitate the fulfillment of the goal. Experiment results prove that the model solve the heterogeneity of the data sources and provide transparent accessing for the end users.
