- Abstract
- Describes the development by the Defence Metallurgical Research Laboratory, Hyderabad, India, of an expert system for classification of technical documents using the UDC schedule for metallurgy as knowledge base and the UDC classification rules as rule base. The scheme was modified from its enumerative structure to an analytico-synthetic structure which is best suited to such an expert system. Some benefits of the expert system are that: it interacts with the classifier making them conform to the route suggested by the classification scheme; it alerts the classifier to the minor variations in the scheme thus avoiding overlooking them; it leads to consistency in class number generation; and it ensures that the classifier has incorporated als the concepts of the subject in the class number, by leading him or her through all the groups, which is not possible in the manual scheme
