Abstract

Information Retrieval in the World Wide Web with general purpose search engines is still a difficult and time consuming task. Specialized search tools have turned out to be much more effective and useful in certain domains. However, their ideas are often trimmed to one special domain so they cannot be applied to set up series of specialized tools. In addition, they tend to induce a tremendous load on the network. This contribution reports our approach for designing specialized search engines, so-called domain experts. These experts gather the documents relevant for their domain through mobile filter agents. We show the effectiveness of domain experts with a case study in the domain of scientific articles. Finally, we demonstrate that the filter agents' mobility can cause a significant reduction of the induced network load.
