Exploiting the semantic graph for the representation and retrieval of medical documents

Empirical experiments are conducted on two different datasets. The results demonstrate that the proposed graph-based approach significantly outperforms the baselines. For example, the average performance improvement on two datasets of the best variant of GSRM compared to the best baseline achieve 7.2% and 7.9% in terms of P@20 and NDCG@20, respectively, which illustrates the effectiveness of the proposed approach.
