From: Kris Hammond <Hammond@YALE.ARPA> [This is a response to a personal query about Kris' work in recipe planning; he agreed to let me share it with the list. I would be interested in hearing about other recipe-based systems, including those in the chemistry domain. -- KIL] I have a paper in AAAI83, Planning and Goal Interaction: The use of past solutions in present situations. My work centers around the notion of organizing planning knowledge around the interactions between features rather than around individual features themselves. In the cooking domain this means the planner has to anticipate the interactions between different tastes and textures, and search for past plans that have already dealt with this interaction in the past. The end result is a system that looks at an input situation, (a request for a dish that includes many items and tastes) and tries to find a recipe for an analogous past situation. The paper is the analysis of an example which uses knowledge of feature interaction to 1) analyze the original input, 2) index into a useful plan, 3) suggest the type of modifications that have to be made on that plan, 4) search for problems in the resulting plan and 5) propose general solutions to the problems encountered. I [am now working on] a more general application of the idea of organizing planning information in terms of goal and plan interaction. [...] The cooking paper in on YALE-RES <A.HAMMOND.WORK>WOK.MSS. Thanks for the interest. Kris Hammond
