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)
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)
