Class Summary

Class	Description
AbstractIterativeScorer<V,E,T>	An abstract class for algorithms that assign scores to vertices based on iterative methods.
AbstractIterativeScorerWithPriors<V,E,S>	An abstract class for iterative random-walk-based vertex scoring algorithms that have a fixed probability, for each vertex, of 'jumping' to that vertex at each step in the algorithm (rather than following a link out of that vertex).
BarycenterScorer<V,E>	Assigns scores to each vertex according to the sum of its distances to all other vertices.
BetweennessCentrality<V,E>	Computes betweenness centrality for each vertex and edge in the graph.
ClosenessCentrality<V,E>	Assigns scores to each vertex based on the mean distance to each other vertex.
DegreeScorer<V>	Assigns a score to each vertex equal to its degree.
DistanceCentralityScorer<V,E>	Assigns scores to vertices based on their distances to each other vertex in the graph.
EigenvectorCentrality<V,E>	Calculates eigenvector centrality for each vertex in the graph.
HITS<V,E>	Assigns hub and authority scores to each vertex depending on the topology of the network.
HITS.Scores	Maintains hub and authority score information for a vertex.
HITSWithPriors<V,E>	A generalization of HITS that permits non-uniformly-distributed random jumps.
KStepMarkov<V,E>	A special case of PageRankWithPriors in which the final scores represent a probability distribution over position assuming a random (Markovian) walk of exactly k steps, based on the initial distribution specified by the priors.
PageRank<V,E>	Assigns scores to each vertex according to the PageRank algorithm.
PageRankWithPriors<V,E>	A generalization of PageRank that permits non-uniformly-distributed random jumps.

Package edu.uci.ics.jung.algorithms.scoring Description

Mechanisms for assigning values (denoting significance, influence, centrality, etc.) to graph elements based on topological properties. These include:

• BarycenterScorer: assigns a score to each vertex according to the sum of the distances to all other vertices
• ClosenessCentrality: assigns a score to each vertex based on the mean distance to each other vertex
• DegreeScorer: assigns a score to each vertex based on its degree
• EigenvectorCentrality: assigns vertex scores based on long-term probabilities of random walks passing through the vertex at time t
• PageRank: like EigenvectorCentrality, but with a constant probability of the random walk restarting at a uniform-randomly chosen vertex
• PageRankWithPriors: like PageRank, but with a constant probability of the random walk restarting at a vertex drawn from an arbitrary distribution
• HITS: assigns hubs-and-authorities scores to vertices based on complementary random walk processes
• HITSWithPriors: analogous to HITS (see PageRankWithPriors)
• VoltageScorer: assigns scores to vertices based on simulated current flow along edges
