Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| HSNL (content LSTM + heterogeneous social random walk) instead of CNTN | cQA answer ranking · Quora cQA, 80% training | nDCG: 0.9101 -> 0.9481 | Helped |
| HSNL instead of S-matrix | cQA answer ranking · Quora cQA, 80% training | Precision@1: 0.5755 -> 0.6701 | Helped |
| HSNL instead of CNTN | cQA answer ranking · Quora cQA, 20% training | Accuracy: 0.2295 -> 0.3645 | Helped |
| add bilinear similarity matrix M (ablation) | HSNL-sim · Quora cQA, 80% training | Accuracy: 0.5556 -> 0.6928 | Helped |
| add bilinear similarity matrix M (ablation) | HSNL-sim · Quora cQA, 20% training | nDCG: 0.5721 -> 0.6286 | Helped |
| add content LSTM and rating-aware ranking loss to DeepWalk (ablation) | DeepWalk · Quora cQA, 80% training | Precision@1: 0.4065 -> 0.6701 | Helped |
| supervised content models (CNTN) instead of unsupervised BOW | cQA · Quora cQA, 20% training | nDCG: 0.6268 -> 0.5367 | Hurt |
