Refining social graph connectivity via shortcut edge addition
Papagelis M. ACM Transactions on Knowledge Discovery from Data 10(2): 1-35, 2015. Type: Article
Small changes to the structure of graphs imply a huge impact on their connectivity. While in a purely theoretical approach, a topological change affects just formal properties, graph data structures associated with well-defined semantics (for exam...

recommendation for cold-start users via cross-domain information
Mirbakhsh N., Ling C. ACM Transactions on Knowledge Discovery from Data 9(4): 1-19, 2015. Type: Article
Collaborative recommender systems often provide disappointing suggestions to new users who volunteered very few or no ratings of their own for processing: this is known as the cold-start problem. Mitigating such shortcomings with cross-domain info...
