PurposeThis study aims to identify the prominent topics, the distribution and association characteristics of topics and the topic evolutionary trends of Documentary Heritage Preservation and Conservation (DHPAC) research in China.Design/methodology/approachKeywords of relevant papers in China National Knowledge Infrastructure (CNKI) were extracted as the data source in this study. First, frequency and co-occurrence of keywords of the selected papers were obtained by using SATI. Second, co-word network indicators were calculated with the Pajek software. Then, VOSviewer was applied to optimize the visualization of the sub-communities. Finally, a topics evolution map of this research field was implemented by CorTexT.FindingsThe research topics of DHPAC research in China were unbalanced but distinct. Topics of DHPAC research in China possessed inconspicuous orientation and consistency. The core topics had less influence on the overall network. A research system had formed with archival conservation and ancient books conservation as the core research directions. Research in this field had formed four continuous evolutionary paths about ancient books conservation, salvage conservation, archival conservation and archives conservation technology science with topics fusion and differentiation coexisting. Attentions on “ancient books conservation”, “paper relics conservation”, “electronic record”, “digitization”, “minority”, “documents in the republic of China” had increased during the past two decades and new hot topics of DHPAC research kept appearing in China.Originality/valueThis study synthesized and analyzed the research results of DHPAC research in China from a more comprehensive perspective and revealed the topic structure and longitudinal evolution process intuitively with co-word analysis and social network analysis, which can assist researchers to improve research systematization, discover new research directions and seek cooperative research path.
Along with the acceleration of social informatization and the increase of users' individual requirements, it becomes difficult for the electronic maps to meet the management needs of the smart scenic spots because there lack of information on real time data and participation of tourists. Digital measurable images (DMI) can make up for the disadvantages of electronic maps effectively. While integrating DMI with the electronic maps, a visual data platform and a true 3D visual management pattern can be built, which makes users enable to observe the scenic spot no matter from any perspective angles and provides personalized services for the different needs of different users. This paper mainly discusses the integration of DMI with the electronic maps and specific applications in Smart Jiuzhaigou.
