Computational models of relevance in case-based legal reasoning have traditionallybeen based on algorithms for comparing the facts and substantive legal issues of aprior case to those of a new case. In this paper we argue that robust models ofcase-based legal reasoning must also consider the broader social and jurisprudentialcontext in which legal precedents are decided. We analyze three aspects of legalcontext: the teleological relations that connect legal precedents to the socialvalues and policies they serve, the temporal relations between prior andsubsequent (...) cases in a legal domain, and the procedural posture of legal cases,which defines the scope of their precedential relevance. Using real examples drawnfrom appellate courts of New York and Massachusetts, we show with the courts' ownarguments that the doctrine of stare decisis (i.e., similar facts should lead to similar results) is subject to contextual constraints and influences. For each of the three aspects of legal context, we outline an expanded computational framework for case-based legal reasoning that encompasses the reasoning of the examples, and provides a foundation for generating a more robust set of legal arguments.

Chinese medicine (CM) is one ofseveral ancient systems of medical care basedupon a different worldview than the prevailingbiomedical model; it employs its own language,systems of logic, and criteria forunderstanding health and diagnosing illness.Medicinal herbs play a central role in the CMsystem of practice and knowledgeable CMpractitioners have extensive clinicalexperience using them. However, the establishedscientific and regulatory organizations thatrely upon biomedical understandings ofpathology do not accept the definitions formedicinal herb quality used by CMpractitioners. Furthermore, local medicinalherb growers within the upper Midwest (...) are in aposition to grow many herbs, but are unclearabout the demand for and desired qualities ofthe medicinal herbs they produce. Given thissituation, the Medicinal Herb Network wasfounded as a partnership effort of small-scalemedicinal herb growers and practitioners of CMto develop more appropriate standards ofmedicinal herb quality and to encourage locallygrown, high quality medicinal herbs consistentwith these standards. An overview of CM servesas grounding from which to articulate thedilemmas experienced by CM practitioners ofperceiving medicinal herb quality andintegrating knowledge across divergent medicalsystems. A Network initiative designed toovercome these dilemmas illustrates thepossibility of developing a lexicon of qualitydescriptors for medicinal herbs using Chinesemedical theory, while drawing from descriptivesensory analysis procedures currently practicedby a sub-group of food scientists.
