Sorry, I left out a piece of the logic chain. One of the key
inhibitors for products like Vivisimo is the need to retrieve
results that have well-known structure other than just rendering
mark-up. So, Vivisimo could metasearch three distinct Z39.50
sources and retrieve results in a chosen schema. Then, the
clustering engine could create separate clusters for "author",
"publication date", "subject", etc., in addition to whatever
clustering may be desirable against the "body of text".
Absent the Z39.50 standard, all they can do is to pick apart
whatever the engineers assume about the HTML returned by the
various servers.
