One problem faced by astronomers using the virtual observatory is finding which of the multitude of data resources is relevant for them. The current tool, VOExplorer, relies on matching searches against tags provided by the resources. This paper shows how skos encoded vocabularies can be used to improve the search results. The techniques are general and applicable to any loose collaborations sharing their resources.
