    <Paragraph position="0"> We advocate the use of an existing rich lexical resource for the nearly-automated creation of hierarchical subject-oriented metadata for information browsing and navigation. We have created examples that show that a modified version of WordNet can produce a useful starting point for information organization projects. These have the added advantage of producing automated assignments of multiple labels to documents. We plan to augment the processing with more intelligent selection of hypernym 2This collection is also used in (Yee et al., 2003).</Paragraph>

The method also worked well on a set of biomedical journal titles; we are in the process of determining how generally applicable the approach is. In addition, we are currently designing usability studies in which we will present different categorization suggestions to information architects to organize. Their subjective reactions, the amount of time it takes them to create the organizations, and the resulting quality and coverage of the organizations, as measured by users performing navigation tasks using the hierarchies, will be compared to other techniques.</Paragraph>
