| Abstract | Smoothing techniques are proposed to address the inherent data sparsity in such graphs, including interpolation using a query synonymy model. |
| Association Model | Smoothing techniques can be useful to alleviate data sparsity problems common in statistical models. |
| Experimental Results | We expect our smoothing models to have much more impact on M SE (i.e., the tail) than on M SEW since head queries do not suffer from data sparsity . |
