CLASSIFICATION AT A CROSSROADS - MULTIPLE DIRECTIONS TO USABILITY
International UDC Seminar 2009

The Hague, 29-30 October 2009

The 2009 Seminar will explore how new developments in information standards and technology influence and affect applications and services using classification and its relationship to other systems.

Two eminent keynote speakers will address the conference: Prof. Karen Markey, School of Information, University of Michigan, a well known author and researcher in the area of improving online information systems and Dan Brickley, an advocate and developer of W3C Semantic Web technologies, who founded and chaired the Semantic Web Development Group from 1999-2005. (see more http://www.udcc.org/seminar2009/speakers.htm)

The conference programme will highlight many ways in which classification use can be improved. Attention will be paid to the applications of classification schemes, UDC in particular, in supporting multilingual access, user-friendly
representations of classification in resource discovery and application across distributed systems.

Papers are invited from classification researchers and practitioners on the following topics:

1. classification and semantic technologies （分类和语义技术）
2. classification in supporting information integration （支持信息整合的分类法）
3. verbal and multilingual access to classification （分类的词语和多语言检索）
4. classification authority control and library systems （分类规范控制和图书馆系统）
5. visual representations/interface to classification （分类的可视表示/界面）
6. experiences with classification outside the traditional library environment （传统图书馆环境以外的分类经验）

Contributions may include conference papers and posters. To read more about the conference and its theme and to submit your abstract, please go to the conference website: http://www.udcc.org/seminar2009/index.htm.

selection of the best papers will be considered for publication in Knowledge Organization, the leading peer-reviewed journal in the field.
