Performance of different methods.

<p>Results are mean (standard derivation) obtained by 10-fold cross-validation experiments on MovieLens (5,000 users and 5,977 objects) with cosine similarity measure. Restart probabilities for random walk approaches are set to 0.9. <i>MRR</i> represents mean relative rank, <i>PR@20</i> represents precision at the default <i>L</i> value of 20, <i>RE</i> represents recall enhancement, <i>HR@20</i> represents hit-rate at <i>L</i> = 20, <i>MP</i> represents mean personalization, <i>MN</i> represents mean novelty.</p><p>Performance of different methods.
