ABSTRACT
With the knowledge about the principles of expert systems and chemical information processing from the previous chapters, we are now ready to look at the program packages that combine these technologies to form expert systems. A series of expert systems has been developed and successfully applied in the area of chemistry in the last four decades, since the rst expert system was published. This chapter gives an overview on noncommercial and commercial systems as well as some detail on the underlying mechanisms for selected examples. The expert systems were selected according to specic application areas, starting with the early Dendritic Algorithm (DENDRAL) project and covering spectroscopic applications, analytical chemistry, property prediction, reaction prediction, and synthesis planning.
