ranking function for XML document streams

Question posted by: Maciej Gawinecki (Guest) on June 27th, 2008 07:07 PM

Hello,

Recently I've interested in quering XML document streams. They can be
queried in keyword- based manner (non-structural queries), as the
authors of the article "Semantic Search over XML Document
Streams" [1]
have shown.

Do you know any ranking function to ranking triples returned during
search ? I'm not a specialist in this field, but this would require
some
ranking function based on local context of a result, as a stream have
a
different natured then indexed documents. For example for indexed XML
documents authors of XRank system proposed a function based on
number of all elements in the document).

What do you think about this ?

Regards,

Maciej,
