UDC online

Technological developments will influence the way in which UDC will be used in the future on the Internet. Thus, in order to “classify” using classification schemes such as UDC, an automatic classification system would ideally “contain” classification numbers as they would be applied in real situations.

Classification schemes used for this purpose would ideally contain simple and compound numbers with the vocabulary established in an authority file. In addition to the list of numbers, an alphabetical subject index is essential and this must be enriched with natural language terms likely to occur in an actual full-text database.

As this is an “authority list” against which the system will compare terms extracted from documents, the list of terms has to be formatted and organized in a machine-readable manner.
