This paper analy-ses the structure of law clauses,proposes a representation model for law knowledge in terms of causal relationships and nonmonotonic reasoning models based on it. These models are successfully applied in the implementation of NBU-CALA+ ,a law expert consultant system for case analysis and interpreta-tion.展开更多
