DENDRAL: A Case Study of the First Expert System for Scientific Hypothesis Formation

If you prefer to suggest your own revision of the article, you can go to edit mode requires login. New graph-theoretic algorithms were invented by Lederberg, Harold Brown, and others that generate all graphs with a specified set of nodes and connection-types chemical atoms and bonds — with or without cycles.

Dendral – Wikipedia

Buchanan and Edward A. In the early s, Dwndral Lederberg started working with computers and quickly became tremendously interested in creating interactive computers to help him expedt his exobiology research. Meta-Dendral is a machine learning system that receives the set of possible chemical structures and corresponding mass spectra as input, and proposes a set of rules of mass spectrometry that correlate structural features with processes that produce the mass spectrum.


Dendral then was still very inaccurate in assessing spectra of ketonesalcoholsand isomers of chemical compounds.
