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

aiming to provide free public service. This paper takes CLC v4.0 as an example, and introduces its
functionalities.

2.1 Introduction of CLC v4.0 Web version of CLSS

2.1.1 Classification scheme browsing and searching
CLC v4.0 Web version of CLSS covers primary table (taxonomic schedules), specific
subdivision tables, and common subdivision tables. It maintains the class entries’ static
contents and formats in printing, while introducing their Linked Data representations.
Representing detailed information of class entries in the form of Linked Data is a highlight of
the CLC v4.0 Web version, which provides various mapping relations with Chinese Classified
Subject Thesaurus (hereafter referred to as CCT), reflecting the idea of classification-subject
integration. In addition, the class numbers in the class entries’ notes, reference class numbers
and other relevant class numbers, are provided with hyperlinks, and are offered with convenient
guidance and operations. They break through the traditional “linear” method of resource
organization and accomplish the reticular browse-path and searching route. There are various
browsing ways, including displaying the complete classification scheme by means of “browsing”
and entering each part of the classification scheme through the index of main classes and
auxiliary tables.
In the Web edition, with the simple, intuitive and humanized interface, users can know clearly
about the hierarchy of items through browsing. Web version provides diversified approaches
for searching, including arbitrary way, class numbers, class names (i.e. headings), and notes.
Matching modes include the arbitrary matching, the forward matching, and the exact matching.
Search results are listed according to the ordering rules of the system. Besides, Web version
provides the mapping from keywords to formal subject term (i.e. descriptor). It can avoid
missing to the greatest extent, ensure the precision, and improve the accuracy of classification
indexing. User can click the wanted class for more details and the operation buttons (various
functions such as opening class numbers or class names for OPAC searching, see Figure 2) in
“browsing” and “searching”.

2.1.2 Classification indexing
CLC v4.0 Web version in this paper provides indexing service. User can enter keywords in the
“searching” to search and get the searching result list, then choose a class directly, or unfold the
classification in the “browsing” then choose a class. On the right hand side, it will show details
of the class entry and the operation buttons. The default indexing is the chosen class number or
built number after subdivision. Upon clicking the “get” button, the class number will be sent
automatically and stored.
