An example of integrating legal case based reasoning with object-oriented rule-based systems: IKBALS II

Although case based reasoning (CBR) is still a research paradigm, it has been shown to offer significant advantages over conventional rulebased expert systems when attempting to reason through experience. This paper discusses extending an existing legal object-oriented/rulebased system to successfully handle CBR. In particular, we discuss the architecture of IKBALS II, a legal knowledge based system that performs statutory interpretation in the area of accident compensation. IKBALS II combines reasoning with rules and reasoning with previously tried precedent cases in order to determine if an injured employee is entitled to compensation under the Accident Compensation Act, 1985, Victoria. A worker is entitled to compensation only if the Accident Compensation Commission is satisfied that the worker falls within certain statutory definitions.
