Betweenness is the extent to which a point gets in between any two
other communicating points. A betweenness indicator, CB, for a point p
k
is

where g
ij
(p
k
) is the number of geodesics linking p
i
and p
j
that contain p
k
, and
g
ij
is the total number of geodesics in the network.
Closeness is the extent to which a point enjoys the minimum number of
points between itself and each other point in the network. It is actually an
inverse function of decentrality, such that d(p
i
, p
k
) is the number of edges
between a point p
k
and all other points. The closeness ...
