Change subject: Use max( |sitelinks|, |labels| ) for term weight.
......................................................................
Use max( |sitelinks|, |labels| ) for term weight.
Considering the number of labels for the term weight boosts
the ranking of items that have no/few sitelinks, but many labels.
This may be true for "structural" items like Q6581097, which
have no corresponding wikipedia pages.
Bug: T94404
