UDC number interpreter/parser
An interpreter (parser) for complex UDC number can be accessed here.
This approach to processing UDC numbers may be useful especially during retrospective conversion or in the context of library systems which do not have authority control or access to the MRF data.

Both are outcome of a research project by Attila Piros (University of Debrecen, Hungary). The list of his publications and presentations on this topic can be found here.

Call for Papers - International UDC Seminar 2017
Faceted Classification Today: Theory, Technology and End Users will take place in London on 14-15 September 2017. The objective of the conference is to revisit faceted analytical theory as a method for (re)constructing modern classifications and indexing languages and the role analytico-synthetic classifications have had in resource discovery and retrieval, from their introduction at the beginning of the 20th century to date.
The conference will examine the challenges analytico-synthetic classifications represent for data modelling and interface design in the Web environment. Most importantly, it will explore potential fields of application for faceted classifications in information organization, visualization and presentation of large datasets, social networks and in the open linked data environment.

High quality and innovative contributions are invited for the following topics:

  • The impact of faceted analytical theory and research on modern classification and indexing languages;
  • Data modelling, data management and data sharing of faceted and analytico-synthetic classifications;
  • Vocabulary mapping, semantic linking and natural language interfacing of analytico-synthetic systems;
  • Applications of faceted analytical theory on (re)constructing knowledge classifications and indexing languages;
  • End user interface design and user-friendly knowledge presentation for faceted systems;
  • Novel applications of faceted systems outside the bibliographic domain.

Two kinds of contributions are invited: conference papers and posters. Read more on the conference website.
