3. DynWing computes and assigns weights to the experts in the trust model dynamically, i.e., on a per-link basis. As combining different experts’ opinions is still an active research area [9], researchers used either static weights computed using oracles [2], [8] or other techniques, e.g., principal component analysis (PCA) [9], for each source of information. However, defining a static weight for all the links for each expert may not be feasible because oracles may not be available or might be too costly to build. Thus, dynamic-weighting techniques are promising to assign weights for each link. DynWing analyzes each expert’s similarity value for each link and assigns weights according to these values.
