Chinese KOS (Ⅱ): Research and implementation of Classification Scheme Sharing Service System

Our research is based on related research results from the NKOS research office of the
Shenzhen University Library and on the Knowledge Organization Standards of NLC. Taking
CLC v4.0 as an example, we use its data in the CLCMARC format or the HTML format
as data source, and convert the source data to CNKOS ontology by computer programs
automatically through the corresponding relationship between source data and SKOS/CKOS
vocabularies, therefore realizing formal semantic description of CLC. The detailed conversion
plan will be given in Section 2.2.

1.2 Classification Scheme Sharing Service System

1.2.1 Overseas and Chinese research status
Copyright owners of international mainstream classification schemes have had their Web
versions published one after another in the 21st century through their continuous efforts. For
example, OCLC, the copyright owner of DDC, took the lead in opening the Web version service
Web Dewey in 2000, followed by two other famous international classification schemes LCC
1①
and UDC releasing their Web versions Classification Web and UDC Online successively

2②
in 2001. Cao,Yan, and D. B. Wang (2002) provided a comprehensive evaluation and analysis
of the earlier Web versions of DDC, LCC and UDC with a detailed comparison of their main
functionalities.
In recent years, there have been many research works on constructions of classification
schemes’ Web versions and even ontology versions of KOSs based on computer network
technology in China (X. Q. Huang, 2000; X. C. Liu & Zuo, 2001; Pan, 2009; He & Hou, 2010;
Zhang, 2012), all of which have agreed on the trend of networked development for classification
schemes. However, there are few practical applications of networked classification schemes,
not to mention the provision of mature knowledge services. In order to make up for those
deficiencies, and by learning from advanced results and application experience of classification
schemes abroad, the National Library of China released the CLC v5.0 Web version online in
December 2011 (National Library of China [NLC], 2011), the original 6-month beta period of
which was extended to September 1st, 2012. L. J. Liu (2012) analyzed the functionalities of CLC
v5.0 Web version in detail, and proposed her own suggestions and outlook. Compared with the
Web versions of DDC, LCC and UDC, the CLC Web version does not provide automatic number
building service.
The publication of classification scheme Web version is only the first step towards a
networked development. Terminology Web service, Linked Data service, automatic classification
