Just go to Special:Ask, create a semantic query that shows what you want 
(see http://ontoworld.org/wiki/Help:Semantic_search ), then copy its URL 
from the location field.  But then there are some tricks to making a 
wiki link to Special:Ask, read on...

On Special:Ask, you don't need the <ask> tags, they're implied.  The URL 
on ontoworld.org for a query for [[Category::Testpage]] is

http://ontoworld.org/wiki/Special:Ask?title=Special%3AAsk&query=[[Category%3ATestpage]]&sort=&order=ASC

you can reduce this to

http://ontoworld.org/wiki/Special:Ask?query=[[Category%3ATestpage]]

Now the trick is to escape the ? [ ] characters.  Mediawiki hopelessly 
garbles a link to
[[Special:Ask?query=[[Category%3ATestpage]]]]

My MediaWiki-fu is not strong.  I think you have to use a template like 
Wikipedia's Template:Querylink to pass a query string to a link, and 
also use HTML entities for the square brackets.  This seems to work:
 
{{Querylink|Special:Ask|qs=query=&#91;&#91;Category%3ATestpage&#93;&#93;}}

That's not a very useful query -- just put a link to 
[[Category:Testpage]] on your page -- but it shows you it's possible.

This query is up for a limited time on http://ontoworld.org/wiki/Sandbox

Special:Ask doesn't give you all the fancy formatting that the <ask> 
inline query does.  If you need it, just create a page titled something 
like  "Semantic query for XYZ", embed the fancy inline query, and link 
to that page.
