  1. Scholarly Paper Recommendation Exploiting Potential Papers 25th November, 2011 Kazunari Sugiyama

  2. Outline of My Former Research • How to construct user profile for scholarly paper recommendation

  3. Publication list new old (‘05) (‘11) (‘02) (‘03) Individual paper Citation papers (‘06) (‘07) (‘09) References (‘05) (‘01) (‘04) (‘03) Reference papers

  4. Outline of My Current Research • How to characterize candidate papers to recommend

  5. Proposed Approach (‘07) (‘09) Potential paper that should cite the target paper (‘06) (‘05) References (‘01) (‘03) (‘04)

  6. How to Find Potential Papers Pi (i=1, … ,N): All papers in the dataset Pcj (j=1, … ,N): Papers as citation papers in the dataset 0.368 0.536 0.211 0.472

  7. Characterize the Target Paper using Potential Papers (‘06) (‘07) (‘09) (‘05) Potential paper that should cite the target paper 7

  8. Paper-Citation Paper Matrix for CF

  9. Experimental Data

  10. Evaluation Measure • Normalized Discounted Cumulrative Gain (NDCG) • nDCG@5, nDCG@10 • Mean Reciprocal Rank (MRR)

  11. Experimental Results • Define optimal values using training set • Neighbors of target paper in CF, Number of potential papers

  12. Experimental Results • Apply optimal values obtained from training set to test set

  13. Conclusion • In order to provide better recommendation, we proposed how to characterize candidate papers to recommend. • Full contents of potential paper gives better recommendation accuracy compared with “fragments only” or “potential paper + fragments”
