Frank McQuillan updated MADLIB-1121:
------------------------------------
Description:
Follow on from https://issues.apache.org/jira/browse/MADLIB-1072. Given that
this story is complete, what measures can we compute from APSP?
Betweenness may use APSP result set, or implement as a separate algorithm,
e.g., [1].

Story
As a MADlib developer, I want to implement the following measures:
1 Betweenness (possibly use APSP)
2 Closeness (uses APSP)
3 Eigenvector centrality
4 Graph diameter (uses APSP)
5 HITS
6 Average path length
7 In/out degrees
8 Clustering coefficient (uses triangle/triplet counting)
Acceptance
1) Interface defined
2) Design document updated
3) Documentation and on-line help
4) IC and Tinc tests
5) Scale tests
