We present a web mining method for discovering
and enhancing relationships in which a
specified concept (word class) participates.
We discover a whole range of relationships
focused on the given concept, rather than
generic known relationships as in most previous
work. Our method is based on clustering
patterns that contain concept words and
other words related to them. We evaluate the
method on three different rich concepts and
find that in each case the method generates a
broad variety of relationships with good precision.
