摘要: In some situations search engine users would prefer to retrieve entities instead of just documents. Example queries include "Italian Nobel prize winners", "Formula 1 drivers that won the Monaco Grand Prix", or "German spoken Swiss cantons". The XML Entity Ranking (XER) track at INEX creates a discussion forum aimed standardizing evaluation procedures for entity retrieval. This paper describes XER tasks and procedure used in 2009, where new version Wikipedia was as underlying collection; summarizes approaches adopted by participants.
