[WikiEN-l] Google results summaries for Wikipedia articles

[Mark Ryan]

I've noticed that in Google results, Wikipedia articles sometimes get
summaries that aren't the page content but are descriptions of it. For
instance, when I search Google for "Australia", the Wikipedia article
(which is at #2 in the results) has this:

"Hyperlinked encyclopedia article covers the country's history,
government and politics, geography, economy, demographics, language
and culture."

Has Google put these summaries into place itself, or is it something
we've done on our end?
