Knowledge generation

This section details the different aspects of the representation we have adopted to describe the problem solutions and the new control knowledge generated by the learning mechanism. Throughout the section we will continue to use the flowshop scheduling problem as an illustration. The section starts by discussing the motives for selecting the horn clause form of first-order predicate calculus, and then proceeds to show how the representation supports both the synthesis of problem solutions and their analysis. The section concludes with a description of how the sufficient... 

The intense need for herbal information in response to consumer interest in natural products was an acute reminder that information and knowledge generated locally have an international role. Confusion created by multiple names and unreliable nomenclature and classification of natural products mirrors problems encountered with drug nomenclature in the 1960s. Our information deficit in this area is still large. Chapter 24 presents a discussion of natural products. 

It is also common when building the knowledge base to find that the insertion of one piece of knowledge generates the need for further material. One step in a chemical analysis may require strongly acidic conditions, which are achieved by using a low pH. This implies that the ES needs to know about pH, which in turn demands an understanding of what is meant by the concentration of H+ ion. This may then require that the ES contains some information that relates to acid dissociation constants. 

It is not clear how the immense base of knowledge generated under the various rubrics of genomics will ultimately be utilized to improve drug safety and the drug development process. What is clear, however, is that it will be some years before such studies displace the current paradigm of testing. 

A general issue in these studies is that the preparation method is quite different from ones used to prepare real catalysts to be tested under practical conditions. This is an important issue, because there is the need to link the micro-kinetic and surface mechanism studies to the catalytic behaviour under real conditions, and to use the knowledge generated by the fundamental investigations to prepare industrially relevant catalysts. 

To predict the polymerization behavior of similar monomers on the basis of the knowledge generated with the 3-methyl-1-butene and 4-methyl-1-pentene systems, which in turn would yield novel copolymers via cationic isomerization polymerization. 

Scheme 33 shows the steps elucidated [76] for the biosynthesis of coenzyme Bi2 4 from hydrogenobyrinic acid 60 in Ps. denitrificans. This collects together the knowledge generated for this organism by the French teams of Blanche and Crouzet. A more complete review of this work and that of others is available [76]. 

They capture explicit knowledge generated within the organization in a centralized or multiple decentralized knowledge repositories.
