Castanet carves out a structure from the WordNet lexical hierarchy, with the goal of building facets that reflect the contents of the target information collection; moderate manual modifications improve the outcome.
The algorithm is simple yet effective: a study conducted with 34 information architects found that Castanet achieves higher quality results than other automated category creation algorithms, and 85\% of the study participants said they would like to use the system for their work.
