TugGraph: Path-preserving hierarchies for browsing proximity and paths in graphs
Many graph visualization systems use graph hierarchies to organize a large input graph into logical components. These approaches detect features globally in the data and place the...

Improved spoken term detection with graph-based re-ranking in feature space
This paper presents a graph-based approach for spoken term detection. Each first-pass retrieved utterance is a node on a graph and the edge between two nodes is weighted by the s...
