Subs and Sandwiches: Replacing One Ingredient By Another

Refereed Conference Meeting Proceeding
The Earl system works in the domain of sandwich recipes. We show how Earl uses two sources of knowledge —ingredients knowledge that is extracted from a gastronomy web site, and a case base of sandwich recipes— to propose substitutes for ingredients in sandwich recipes. In particular, we describe four substitution methods: human-authored substitutions, taxonomically-driven substitutions, lexically-driven substitutions, and frequent item set substitutions. A preliminary experiment with human participants shows that a system that uses the last of these methods is competitive with one that uses the other three methods in combination.
