چکیده
This paper describes the participation of the SNUMedinfo team at the CLEFeHealth2013 task 3. We submitted 7 runs in total: 1 baseline run using query likelihood model in Indri search engine; 3 runs using passage based language model; 3 runs using passage based language model with lexical query expansion. We tried to incorporate passage-based score into ranking model to reflect the degree of query term cohesion per each document.
