Document understanding techniques such as document clustering and multidocument summarization have been receiving much attention recently. Current document clustering methods usually represent the given collection of documents as a document-term...

Indexing Network Structure with Shortest-Path Trees
Marc Maier, Matthew Rattigan, David Jensen
Article No.: 15
DOI: 10.1145/1993077.1993079

The ability to discover low-cost paths in networks has practical consequences for knowledge discovery and social network analysis tasks. Many analytic techniques for networks require finding low-cost paths, but exact methods for search become...
