Evaluation results for the Social Book Search task

The evaluation results shown below are based on the official INEX 2012 SBS topic set based on the LibraryThing discussion groups and the user profiles and catalogues of the topic creators..

These are the official Qrels:

  1. inex12SBS.LT.qrels.official: Qrels derived from the books recommended on the LibraryThing discussion threads of 101 topics. Each book suggested by a forum member is considered relevant to the requested topic and has relevance value rv=1. Books that are subsequently catalogued by the topic creator in their personal LibraryThing catalogue are considered the best suggestions and have a relevance value rv=4.
The Qrels set uses the LibraryThing work IDs as document IDs. For evaluation the ISBNs in the submitted runs are mapped to LT work IDs as well, with the highest ranked ISBN being mapped to the work ID and lower ranked ISBNs mapped to the same ID removed from the results list.

Deduplication: mapping ISBNs to LibraryThing work IDs
