The Construction and Linked Data Publishing of Dunhuang Mural Thesaurus

Thesauri play an important role in knowledge organization.Nevertheless,the absence of Dunhuang mural thesaurus sets limits on Dunhuang mural studies and its value exploration.The development of the thesaurus is a foundation work of information resource management of Dunhuang murals,which can not only provide a controlled and structured vocabulary for the standardized information resource organization of Dunhuang murals but also provide a clear knowledge system for Dunhuang murals researches. In order to speed up the construction of thesaurus and meet the needs of dynamic updating of knowledge organization,the development of thesaurus needs to adopt the machine assisted semi-automatic cooperative development strategy,and give full play to the advantages of machine and experts,and realizes the rapid development and maintenance of thesaurus through human-computer cooperation. This paper presents the method and procedure of the constructing and linked data publishing of Dunhuang mural thesaurus.A combination of top-down and bottom-up approach was used to develop the thesaurus.The top-down approach starts at the higher-level categories,and establishes a general framework for the thesaurus based on the objectives of the thesaurus. The basic structure of the thesaurus was developed by referring to the fundamental dictionary of Dunhuang studies and Art & Architecture Thesaurus(AAT). The thesaurus contains 5 facets including agents,objects,activities,time and physical attributes. Sub-categories were defined for each facet with total 25 second-level categories. The bottom-up approach builds up lowerlevel categories from the concepts extracted from the corpus with the help of natural language processing technology,and through the process of manually grouping and classification of the terms,definition of the semantic relations,adjustment and optimization of the structure. At present,Dunhuang mural thesaurus contains 4 276 terms. After that,this paper studied and implemented linked data publishing of the Dunhuang mural thesaurus
