Automatic Taxonomy Generation - A Use-Case in the Legal Domain
This addresses the need for faster information retrieval in the legal domain, though it is incremental as it builds on existing methods for taxonomy generation.
The paper tackled the problem of automatically generating a taxonomy of legal concepts to facilitate easier access to legal knowledge for practitioners and researchers, by applying and comparing two approaches on a corpus of UK statutory instruments.
A key challenge in the legal domain is the adaptation and representation of the legal knowledge expressed through texts, in order for legal practitioners and researchers to access this information easier and faster to help with compliance related issues. One way to approach this goal is in the form of a taxonomy of legal concepts. While this task usually requires a manual construction of terms and their relations by domain experts, this paper describes a methodology to automatically generate a taxonomy of legal noun concepts. We apply and compare two approaches on a corpus consisting of statutory instruments for UK, Wales, Scotland and Northern Ireland laws.
