There's another source of data for training library relevance ranking that I
don't think has been exploited much yet.
(for academic libraries)
Searches against catalogs are usually intended to locate material to fill a
specific information need.
Often this information seeking results in circulati
In Mendeley we are using number of readers to rank search results on
our catalog.
Our search index is in solr.
I don't have more fine grained details, but I could get them if people
are interested.

In OCLC Research we do practically nothing without some sor
A bunch of us are using Solr/lucene for discovery over library
bibliographic records, which is based on the basic tf*idf weighting type
algorithm, with a bunch of tweaks. So all of us doing that, and

posts and presentations on this topic, again and again possible ranking
factors are discussed beyond well known term statistic based methods
like the vector space ret
