Components
Legal
HYPO, like any other CBR system has also the following components:
Similarity/relevancy metrics: that is, standards by which to evaluate the closeness of cases, judge their relevancy to the instant case, and select “most on point” cases.
Half-Order Theory of the Application Domain: that is, hierarchies and taxonomies of knowledge, especially regarding the application domain.
Precedent-based argumentation abilities: that is, capabilities to generate and evaluate precedent-based arguments.
Knowledge to generate hypotheticals: that is, the ability to generate hypothetical cases to deal with various circumstances, like testing the validity of an interpretation or argument by providing
Functionality
HYPO’s method of creating an argument and justifying a solution or position has several steps. HYPO begins its processing with the current fact situation (“cfs”) which is direct input by the user into HYPO’s representation framework. Once the user inputs the case, HYPO begins its legal analysis. The cfc is analyzed for relevant factors. Based on these factors HYPO selects the relevant cases and produces a case-analysis-record that records which dimensions apply to the cfc and which nearly apply (i.e. are “near misses”). The combined list of applicable and
An intelligent legal tutoring system
Legal expert systems are specifically designed to teach an area of law and are useful for
HYPO’s progeny
The quality of HYPO’s results speak for themselves, in that a number of sequent legal reasoning systems are either directly based upon HYPO’s mechanisms as in the case of Kowalski (1991)[21] , TAX-HYPO, precedent case-based system operating in the statutory domain of tax law (Rissland and Skalak 1989), CABARET, a mixed-paradigm cases and rule system for the income tax law domain, (Skalak and Rissland 1992) , CATO, IBP, developed for argumentation to make predictions based on argumentation concepts (Brüninghaus and Ashley 2003), or their creators at least pay homage to HYPO in their discussions (Henderson and Bench-Capon 2001[22] ).
