Query: Development of a VO Registry Subject Ontology using Automated Methods   We report on our initial work to automate the generation of a domain ontology
using subject fields of resources held in the Virtual Observatory registry.
Preliminary results are comparable to more generalized ontology learning
software currently in use. We expect to be able to refine our solution to
improve both the depth and breadth of the generated ontology.
