4) Except the duplicate checking for classification, all search functions are implemented using the
Lucene full-text search toolkit, the specific implementation methods is available in X. H. Zeng et al. (2010).
The CLC Web version of CLSS offers the public a free and open sharing service platform, where
the interface is simple and intuitive, and the user experience is quite friendly. Comparing with the
electronic edition, there is no need for installing any software, and no storage device to carry. Any
other Chinese classification scheme can be quickly deployed with this solution.

3 The terminology Web service of classification scheme

The terminology Web service of classification scheme refers to the Web services for browsing,
searching and applying classification scheme. The terminology Web service of vocabulary supports
machines to access and call to vocabulary via Web Application Program Interface (API), and it’s
an important approach to using vocabulary in the network environment (Ou & Yu, 2011).
To further offer the machine-oriented terminology Web service of classification scheme, a series
of Web Service APIs have been developed to provide flexible services as required. They are used
to fulfill the needs of machine, system and application programs. In the future, the APIs of various
classification schemes may be intensively provided via the Terminology Service Registration
Platform, for users’ free selection and call. On the platform, the Web service available classification
schemes would be listed, described and indicated, and each classification scheme would be identified
by URI, so as to promote the finding, reusing and interoperability of classification schemes.
Geared to the actual needs of classification schemes’ networked applications, the set of Web
Service APIs offered by CLC v4.0_CLSS are listed on NKOS Research Office’s website . By

the standard method of Web Service call, all applications could be implemented on different
application platforms . In this section we conduct experiments with books of the Shenzhen
2②
University Library that have no need to be subdivided. Invoking the automatic classification API
of the Terminology Web Service of CLC 4.0, the expectant classification results could be usually
obtained. As for the subdivision-need situation, we randomly extracted two books shown in Table 4
to validate, and the classification result is as shown in Figure 4. These experiments have proven
that Terminology Web Service of classification scheme in this paper can support the computer
cataloging system to automatically assign class numbers to books, periodicals, dissertations and
other information resources that have been indexed with subject terms or keywords. The services
provided by APIs could be used in Library Information Management Systems, Database Retrieving
Systems, Search Engines, Tag Systems, etc., and could match any kind of development platforms
and development languages, to achieve the intelligent retrieval, classification indexing, knowledge
linking and knowledge service based on classification schemes.
