The family of threshold algorithm (i.e., TA) has been widely studied for efficiently computing top-k queries. TA uses a sort-merge framework that assumes data lists are pre-sorted...
Personalized PageRank, related to random walks with restarts and conductance in resistive networks, is a frequent search paradigm for graph-structured databases. While efficient ba...
Efficient full-text searching is a big challenge in Peer-to-Peer (P2P) system. Recently, Distributed Hash Table (DHT) becomes one of the reliable communication schemes for P2P. Som...
