Scalable semantic overlay generation for p2p-based digital libraries
TL;DR: An unsupervised method for decentralized and distributed generation of SONs, called DESENT, is proposed and it is shown through simulations that, when compared to flooding, this approach improves recall by more than 3-10 times, depending on the network topology.
Book ChapterDOI
