We describe Castanet, an algorithm for automatically generating hierarchical faceted meta-data from textual descriptions of items, to be incorporated into browsing and navigation interfaces for large information collections. From an existing lexical database (such as WordNet), Castanet carves out a structure that reflects the contents of the target(More)

Hierarchical faceted category systems for search and browsing have been shown to be useful for large information collections. Castanet is an algorithm for automatically generating hierarchical faceted metadata using text descriptions of items in the collection and WordNet, an existing lexical database. The present study evaluates Castanet and two other(More)
