Abstract. A materialized faceted taxonomy is an information source
where the objects of interest are indexed according to a faceted taxon-
omy. This paper shows how from a materialized faceted taxonomy, we
can mine an expression of the Compound Term Composition Algebra that
specifies exactly those compound terms that have non-empty interpre-
tation. The mined expressions can be used for encoding compactly (and
subsequently reusing) the domain knowledge that is stored in existing
materialized faceted taxonomies. Furthermore, expression mining is very
crucial for reorganizing taxonomy-based sources which were not initially
designed according to a clear faceted approach (like the directories of
Google and Yahoo!), so as to have a semantically clear, and compact
