A-Hohfeld: a language for robust structural representation of knowledge in the legal domain to build interpretation-assistance expert systems
Layman E. Allen, Charles S. Saxon · eYLS (Yale Law School) · 1994
The A-Hohfeld language is presented as a set of definitions; it can be used to precisely express legal norms. The usefulness of the AHohfeld language is illustrated in articulating 2560 alternative structural interpretations of the four-sentence 1982 Library Regulations of Imperial College and constructing an interpretation-assistance legal expert system for these regulations by means of the general-purpose Interpretation-Assistance legal expert system builder called MINT. The logical basis for A-Hohfeld is included as an appendix.
