CrimeNet
Explorer
is a
prototype
system
for
exploring
criminal
networks
in law
enforcement
and
intelligence
domain.
It is
a knowledge
management
tool
intended
to facilitate
the
investigation
of organized
crimes
such
as terrorism,
narcotics
trafficking,
gang-related
crimes
and
many
others.
In these
crimes
offenders
are
interrelated
and
they
operate
in a
network
to commit
various
illegal
activities.
CrimeNet
Explorer
can
help
identify
the
central
members,
detect
the
groups,
and
extract
the
structure/organization
in criminal
networks
based
on criminal-justice
data.
The
major
technologies
used
are
Social
Network
Analysis
(SNA)
methods
(centrality
measures
and
blockmodeling),
clustering,
concept
space
approach,
and
multidimensional
scaling
(MDS).

Figure
2
(The
Reduced
Star
Structure
of
the
Gang
Network):
Circles
represent
groups.
The
size
of
a
circle
is
proportional
to
the
number
of
group
members.
Each
group
is
labeled
by
its
leaders
name.

The
rankings
of
each
group
member
in
terms
of
centrality
measures.
The
first
one
of
each
column
is
the
leader,
gatekeeper,
and
outlier,
respectively.
Adjust
the
slider
