Removal policies in network caches for World-Wide Web documents
We determine the maximum possible hit rate and weighted hit rate that a cache could ever achieve, and the removal policy that maximizes hit rate in each of the studied workloads. Expand

Caching Proxies: Limitations and Potentials
We assess the potential of proxy servers to cache documents retrieved with the HTTP protocol, and show that a proxy server has a 30-50% maximum possible hit rate no matter how it is designed. Expand

Streams, structures, spaces, scenarios, societies (5s): A formal model for digital libraries
We propose the fundamental abstractions of Streams, Structures, Spaces, Scenarios, and Societies (5S), which allow us to define digital libraries rigorously and usefully. Expand

Automatic document metadata extraction using support vector machines
We describe a support vector machine classification based method for metadata extraction from header part of research papers and show that it outperforms other machine learning methods on the same task. Expand

Combining the Evidence of Multiple Query Representations for Information Retrieval
We report on two studies in the TREC-2 program that investigated the effect on retrieval performance of combination of multiple representations of TREC topics. Expand
