Abstract

This paper assesses the retrieval effectiveness ofautomatically constructed inter-document hypertext links inInformation Retrieval (IR). The objectives of the experimentsdescribed are to obtain evidence concerning the usefulness ofquerying and browsing automatically constructed IR hypertexts. Linksare built by using IR techniques, as these enable rapid, automaticproduction of hypertexts from a document collection for accessing thecollection itself. These tests are carried out in a laboratoryenvironment and through simulation of link browsing. Results ofexperiments show that browsing has little impact on the retrieval ofrelevant documents if used in place of querying or relevance feedbackmethods, though may be practical if used in combination withthem.
