Taxonomy Design

This chapter discusses the design of taxonomies to be used in dynamic taxonomy systems. Although the only actual requirement of dynamic taxonomies is a multidimensional classification, i.e., objects are classified under more than one concept, an organization by facets is normally used. In the first section, we provide guidelines for the design of DT taxonomies, which include the automatic construction from structured data, and the retrofitting of traditional monodimensional taxonomies. In the second section, we show how a faceted taxonomy can be automatically extracted from the infobase itself when objects are textual or are described by textual captions or tags.
