Data governance is not only data access,but also data reuse,and its goal is not only data sharing
but also open data. It relies on the coordinated action among public sectors,enterprises,publics
and stakeholders on the idea “as open as possible,as closed as necessary”. In general,data-sets
must undergo the cost and risk assessment of national security,individual privacy,data security
and business interests before release. Released data-sets are findable,accessible,interoperable and
reusable. As a nonprofit agency which does not represent any special interest group,the library is
the reliable data filter and release channel.
Data governance is the foundation of knowledge communication,processing and creation.
As raw materials of the knowledge industry,data values depend on technologies and social
organization of their age. Therefore,they may not be recognized at that time. It is the library’s
responsibility to store and utilize such raw materials. By searching and collecting best
practices,better data governance will be gradually achieved.

Analysis of the quality of semantic mapping and its influencing factors:A case
of the National Thesauri Warehouse’s semantic mapping

The National Thesauri Warehouse is an integrative service system of the thesaurus resources of
China. Its construction is a large and complex project,which includes many aspects while its
core part lies in the semantic integration of multi-thesaurus. Based on the concept of semantic
integration,the National Thesauri Warehouse takes Chinese Thesaurus as the center vocabulary
and uses other Chinese thesaurus mapping to the center vocabulary.
To explore the effect of interdisciplinary on the National Thesauri Warehouse semantic
mapping,we select 5,120 concepts from the environmental science classes of 8 thesaurus and 8,329
concepts from the environmental science class of Chinese Thesaurus to take mapping experiments.
By analyzing the results of automatic matching,we find that the existence of quasi-
synonyms,related words,hyponyms/hypernyms in words of equal relationships,especially
inconsistent mapping methods of two thesaurus for synonyms,causes many logical problems in
multi-thesauri mapping,such as one concept equivalent mapping to multiple concepts or multiple
concepts equivalent mapping to one concept. Since the notion of equivalent mapping is the
foundation for recognizing and processing other mapping relationships,it can be further developed
to hierarchical mapping and relevant mapping,and thus to enrich the network relationships among
the conceptual nodes. Therefore,the main purpose of this paper is to study the logical problems
generated by equivalent mapping.
In this paper,we analyze the forms of the logical problems and the causes at different
