Abstract

Analogical reasoning: An organic chemistry application M. Py 5, France FRAMENTEC-COGNITECH, 1 Place de la coupole, 92084 Paris La defense, France ABSTRACT The purpose of this paper is to describe a formal framework able to reason by analogy. It is constituted by two models, one from the French analogical research group [6], the other from rational agent [26, 25]. The first defines the notions used to reason by analogy. The second deals with knowledge management by learning and verification. Our framework is validated by the experimental results of the rational-agent prototype implemented on a complex range (i.e. the synthesis of molecules in organic chemistry). INTRODUCTION Synthesis in organic chemistry is difficult. It consists of creating a molecule according to a set of known reactions. A molecule can be considered as a coloured graph, and reactions as operators on graphs. To show the difficulties of the synthesis problem, let us simplify it. If
