Topic Difficulty Prediction in Entity Ranking
[chapter]
2009
Lecture Notes in Computer Science
Preserved Fulltext
In this paper, we show that the knowledge of predicted classes of topic difficulty can be used to further improve the entity ranking performance. ...
Many approaches to entity ranking have been proposed, and most of them were evaluated on the INEX Wikipedia test collection. ...
Acknowledgements Most of this work was completed while Vladimir Naumovski was doing his internship at INRIA in 2008. ...
