[Method / Process] This paper expounds on the current situation and the meaning of the power mechanism and the types of the driving forces in social forces' participation in the construction of public cultural services, and analyzes the advanced typical case of social forces' participation in the construction of public cultural services. [Results / Conclusions] Combined with the case analysis, the paper puts forward the optimization strategy for social forces' participation in the construction of public cultural services, which can provide references for promoting the supply of political and social cooperation in public cultural services.

[Purpose / Significance] Voluntary service is a form of voluntary non-profit social welfare activity. With the development of the public cultural system in China, the important role of voluntary service organizations has gradually emerged. [Methods / process] This paper first reviews the current situation of voluntary service organizations' participation in the supply of public cultural services in China, and then based on the analysis of three cases, it points out several major problems and puts forward optimization strategies, to provide references for voluntary service organizations in their participation in the supply of public cultural services. [Results / Conclusions] At present, the main problems of voluntary service organizations in their participation in the supply of public cultural services in China are: supporting policies need to be formulated, and the integration of volunteers' participation and service supply needs to be improved; voluntary service funds need to be raised from diversified sources, and the supply of cultural services lacks autonomy; the interaction between volunteers and the public is not smooth, and the multi-level supply of cultural services needs to be developed; the internal management of organizations is not standardized and the mechanism of introducing and cultivating high-quality talented people needs to be improved. The relevant government departments and voluntary service organizations need to take corresponding measures to solve the problems in time.

[Purpose/Significance] In the context of the country vigorously promoting nationwide reading and constantly improving the public cultural service system, China's public libraries continue to innovate their service models, introduce social forces and seek cooperation with bookstores to form a new model of integrated development. [Method/Process] The paper first introduces the policy background and practice of the integrated development mode of libraries and bookstores and summarizes the current cooperation projects between public libraries and bookstores in China.

[Purpose / Significance] Chuzhou Library is the first prefecture-level library in the country to provide overall service outsourcing. Its exploration of introducing social forces to participate in public library service innovation is of great significance to the current construction and improvement of China's public cultural service system. [Method / Process] Based on the social and policy background of social forces' participation in the service innovation of public libraries, this paper discussed the innovative services of social forces in their participation in Chuzhou Library's construction from five different perspectives: construction, management, services, promotion and institution innovation. This paper summarizes several problems in the development of Chuzhou Library: the public's enthusiasm towards public libraries remains low; local characteristics are not deeply explored; the reader activities create low cultural benefits; the sustainable development of the Library is threatened due the excessive dependence on outsourcing. [Results / Conclusions] The paper suggested that public libraries should establish and improve their mechanism in motivation, association, operation and risk control in order to better engage the social forces in the future.

[Purpose / Significance] As the basis of improving data value, data governance is a research hotspot in the data age. The systematic review of the current research into data governance will help to promote the theoretical research and the practice of electronic information resource management. [Method / Process] Using the methods of literature analysis, the paper systematically analyzes the research progress of data governance from six dimensions: the goal, the subject, the object, the content, process and means of data governance. [Results / Conclusions] Among the core elements of data governance, researchers have the consistent understanding of the goal, the subject and the means of data governance, while their understanding of the key points of the content of data governance needs to be further unified. The research into the object of data governance needs to be specified. In the future research into data governance, researchers should further distinguish between data management and data governance, clarify the positioning of data governance, and place an emphasis on the focus and core content of data governance.

[Purpose / Significance] In order to deeply utilize fishery patent literature in "fishery knowledge service system", we construct a specialized taxonomy for the information organization and test it as an indexing tool in the system. [Method / Process] First, 10, 323 metadata of Chinese fishery patents are selected and analyzed in terms of 4-digit and 6-digit IPC numbers frequency. Based on the results, 12 IPC classification codes are chosen as categories in fishery patent literature classification. Then, based on the analysis of patent titles, it is proposed that a patent title consists of three kinds of phrases: those of industry attributes, of business types, and of invention types, among which phrases of business types are the most applicable for classifying and indexing patent literature. In addition, the subject terms and the ending parts of subject terms are analyzed and the high-frequency subject terms and words of each business type are ranked. Last, the strategy of indexing fishery patent literature by using IPC classification numbers and high frequency subject terms is put forward, and as a result, most of the fishery patent literature is classified properly with the assistance of computers. [Results / Conclusions] Giving that the total accuracy rate of machine indexing is 91.44%, and the missing rate is 7.94%, with the comparison between the manually classified and machine classified sampling data of patent literature in 2016, it is concluded that the goal of this study is achieved. The research shows that the classification system constructed from fishery patent literature is practical and the indexing strategy has a high application value.
