"Austrian On-Line Archive Processing: Analyzing Archives of the World Wide Web";
in: "Proceedings of the 6th European Conference on Research and Advanced Technology for Digital Libraries (ECDL 2002",
With the popularity of the World Wide Web and the recognition of its
worthiness of being archived we find numerous projects aiming at creating
large-scale repositories containing excerpts and snapshots of Web data.
Interfaces are being created that allow users to surf through time,
analyzing the evolution of Web pages, or retrieving information using
search interfaces. Yet, with the timeline and metadata available in such a
Web archive, additional analyzes that go beyond mere information
exploration, become possible.
In this paper we present the AOLAP project building a Data Warehouse of
such a Web archive, allowing its analysis and exploration from different
points of view using OLAP technologies. Specifically, technological aspects
such as operating systems and Web servers used, geographic location, and
Web technology such as the use of file types, forms or scripting languages,
may be used to infer e.g. technology maturation or impact.
