Topic Maps as a Virtual Observatory tool [PDF]
, 2001 One major component of the VO will be catalogs measuring gigabytes and terrabytes if not more. Some mechanism like XML will be used for structuring the information. However, such mechanisms are not good for information retrieval on their own.

Automated supervised classification of variable stars I. Methodology [PDF]
, 2007 The fast classification of new variable stars is an important step in making them available for further research. Selection of science targets from large databases is much more efficient if they have been classified first.
