service, etc. are all needed for a broader sharing, and are of significant importance for traditional
KOSs to be accessible outside the relatively closed library sector, for the realization of Web
service integration and sharing, and for linking information resources inside and outside the
library.
The CLSS system, which this paper studies, is a networked sharing platform with the
combination of functions, such as classification scheme Web version, Web service, Linked Data
service and automatic classification. The solution this paper offers aims at all classification-
like Chinese networked KOSs, hoping to serve as a reference and support for related groups and
individuals to construct networked applications of various classification-like Chinese KOSs both at
home and abroad.

1.2.2 General structure of Classification Scheme Sharing Service System
CLSS firstly converts an existing classification scheme (taking CLC v4.0 as an example) to
a CNKOS ontology, constructs index by using the Lucene full-text index toolkit, and then
realizes networked sharing services through B/S model based on J2EE platform, offering
networked sharing services such as classification scheme Web version, terminology Web
service, Linked Data, automatic classification, etc. The general structure of the system is shown
in Figure 1.

2 Classification scheme Web version

The so-called classification scheme Web version is the classification scheme version that is
browsed, searched, retrieved and even updated on the Web (Cao et al., 2002). Currently, Web
versions provided by DDC, LCC, UDC or CLC are paid services. Normally, network users can
apply for a free trial period. The CLSS solution is oriented to all classification-like Chinese KOSs,
