Efficient Web-Based Information Systems

Abstract

Many approaches have been developed in the past to address efficient query processing for information systems, integrated systems, as well as Web-based systems (caching, etc.). However new techniques need to be developed to optimize query processing for Web-based information systems (WIS). These new techniques need to address several challenges including management and publication of semi-structured data, limited access to Web data sources, lack of published information about their content (statistics, metadata), complex coverage, etc.

This is the first of (hopefully) a successful series of workshops dedicated to efficiency measurements and enforcement of Web-based information systems. The EWIS workshop aims to bring together researchers and practitioners to discuss the use and the development of next generation WIS, ranking from simple Internet/Intranet-based ones to much more dedicated ones such as GRID platforms, which allows to couple geographically distributed resources with an inexpensive access to these resources irrespective of their physical location or access point.

The program consists mainly of a scientific track, of which the papers that appear in these proceedings. For this track the program committee selected 6 papers out from the fifteen submitted. In addition, the workshop program includes an invited paper that describes the ARTEMIS/MOMIS system for semantic integration and query optimization of heterogeneous data sources.
