    Legal documents generally contain a rich set of authorities and references including cases, legislation and law journal articles. This underlying structure can be utilised to facilitate different forms of searching and categorisation. Patterns of references can be used to describe materials falling in distinct clusters. Applications of this approach discussed in the paper include: lateral search (that is, using vectors of similar reference patterns, to find related materials) ; automated creation of subject indices (including identification of conceptual hierarchies) ; and generation of document descriptions.
