Knowledge Engineering

Knowledge engineering (KE) was defined in 1983 by Edward Feigenbaum, and Pamela McCorduck as follows:

KE is an engineering discipline that involves integrating knowledge into computer systems in order to solve complex problems normally requiring a high level of human expertise.

At present, it refers to the building, maintaining and development of knowledge-based systems. It has a great deal in common with software engineering, and is used in many computer science domains such as artificial intelligence, including databases, data mining, expert systems, decision support systems and geographic information systems. Knowledge engineering is also related to mathematical logic, as well as strongly involved in cognitive science and socio-cognitive engineering where the knowledge is produced by socio-cognitive aggregates (mainly humans) and is structured according to our understanding of how human reasoning and logic works.

Various activities of KE specific for the development of a knowledge-based system:

  • Assessment of the problem
  • Development of a knowledge-based system shell/structure
  • Acquisition and structuring of the related information, knowledge and specific preferences (IPK model)
  • Implementation of the structured knowledge into knowledge bases
  • Testing and validation of the inserted knowledge
  • Integration and maintenance of the system
  • Revision and evaluation of the system.

Being still more art than engineering, KE is not as neat as the above list in practice. The phases overlap, the process might be iterative, and many challenges could appear.

Famous quotes containing the words engineering and/or knowledge:

    Mining today is an affair of mathematics, of finance, of the latest in engineering skill. Cautious men behind polished desks in San Francisco figure out in advance the amount of metal to a cubic yard, the number of yards washed a day, the cost of each operation. They have no need of grubstakes.
    Merle Colby, U.S. public relief program (1935-1943)

    Although your knowledge is weak and small, you need not be silent: Since you cannot be judges be at least witnesses.
    Franz Grillparzer (1791–1872)
