querying for ontology usage statistics

Does anyone know how  to determine (without building a custom crawler) the 
popularity of ontologies based on their use in LOD documents.  I suspect 
this can be done via appropriate querying of semantic web search engines, 
but I'm not sure how. If anyone has good advice, I'll be grateful.

Many thanks,
Joel.
