Learning and Analogical Reasoning in the IBS for Organic Synthesis Research

Abstract

　This paper reports an information system called OS-IBS (Organic Synthesis Information-Base System) with elaborated functions such as machine learning, analogical reasoning etc. Machine learning is realized by structuralizing the information, I. E. by generating links automatically and analogical reasoning is realized by evaluating analogical relationship such as similarities of chemical structures, reaction patterns etc. The source information of OS-IBS came from a database system called CORES which has been developed to store and to manage information necessary for research of organic syntheses.
