CHIRON: Planning in an Open-Textured Domain

Kathryn E. Sanders

October 1994


Most work in artificial intelligence and law has concentrated on modelling the type of reasoning done by trial lawyers. In fact, most lawyers' work involves planning -- for example, wills and trusts, real estate deals, and business mergers and acquisitions. Certain planning issues, such as the use of underspecified, or ``open-textured'' rules, are illustrated especially clearly in this domain.

In this thesis, I set forth the characteristic features of planning in law, place it in the context of past artificial intelligence work in both law and planning, and describe {\sc chiron}, a system that I have developed implementing my theory of open-textured planning in the domain of personal income tax law.
