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)
The most popular criterion cited in the dance literature for advancement to pointe work is attainment of the chronological age of 12 years. However, dancers at this age vary greatly in terms of musculoskeletal maturity and motor skill development. The purpose of this study was to investigate whether objective, functional tests could be used in conjunction(More)
This paper introduces two families of orthogonal polynomials on the interval (-1,1), with weight function [Formula: see text]. The first family satisfies the boundary condition [Formula: see text], and the second one satisfies the boundary conditions [Formula: see text]. These boundary conditions arise naturally from PDEs defined on a disk with Dirichlet(More)
There is no widely accepted means of evaluating category systems for information search and browsing. This presentation outlines an evaluation scheme and an evaluation method that applies the scheme. The scheme delineates features broadly classified under comprehensiveness, coherence, and correctness. The method evaluates the category system through a(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)
