[Purpose/Significance] This paper constructs a dynamic knowledge recommendation service model oriented to online academic communities based on ternary interactive determinism to provide a theoretical basis for online community multi-dimensional demand analysis and demand evolution trend description, to improve the knowledge community recommendation services. [Method/Process] Firstly, based on the ternary interactive determinism, we clarify the internal and external factors that affect the user's knowledge needs and analyze the relationship between the factors. Secondly, according to the needs analysis objective of the ternary interactive determinism, we clarify the corresponding analysis methods and extract the characteristics of users' knowledge needs in various dimensions. Finally, we integrate the demand characteristics of various dimensions and build a knowledge demand chain to describe the evolution of user demand under the interaction of the three elements. We use the similarity of the demand chain to calculate and predict the future knowledge demand of users to expand the analysis of users' knowledge demand. [Results/Conclusions] The knowledge recommendation service system based on the ternary interactive determinism fully considers the various influencing factors of user needs from a global perspective, improves the fine-grained characterization of user needs in the community, and provides reference for academic communities to improve their knowledge service levels.

[Purpose/Significance] This paper aims to explore whether there are differences in the title and abstract, citation content, and full-text content on research topic, and analyze whether the topic content in the title and abstract can reveal the research content of the full text and the effect of the citation content on the content of the citing literature, so as to provide theoretical support for analyzing the research content of the full text based on the title and abstract of the literature. [Method/Process] This paper conducts an empirical study using Chinese journal papers in the field of COVID-19, extracts feature words from the titles and abstracts, citations and full-text contents of the literature, uses the clustering algorithm to cluster the feature words, and then uses manual interpretation to identify the research topics, and conducts a comparative study to analyze the topic differences among the three parts. [Results/Conclusions] The results show that: the research topics are different in the title and abstract, citation content and full-text content of the literature; compared with the title and abstract, the full text contains more topic content, but the difference in the topic content is small, so the topic content in the title and abstract can be used to represent the research content of the full text; the content of the citation is related to the topic of the citing literature, and they can complement each other.

[Purpose/Significance] Identifying the contextual factors of information needs is of great significance for understanding the generation mechanism of information needs. [Method/Process] Based on the background of the outbreak of COVID-19, this study crawled the question data from the Baidu Zhidao between December 31 in 2019 and March 30 in 2020, using methods such as content analysis and co-occurrence network analysis to identify the themes of netizens' information needs and the associations between them, and discover the characteristics of different information need themes under various contextual factors. [Results/Conclusions] This study extracted 8 primary themes and 33 secondary themes to reflect the information needs of netizens during the COVID-19 pandemic. The top five information needs with the highest attention from netizens are: impacts, preventions, controls, knowledge and education, and symptoms and treatments. From the perspective of the correlation analysis between themes, the relationship between impacts and controls is the strongest, and worries about infection are closely related to symptoms and treatments. In addition, the contextual factors of netizens' information needs are mainly characters, regions, places, and activities. This research provides support for researches on the relationship between information needs and contexts of netizens in public health emergencies, and helps relevant departments provide information to the public in a timely, efficient and accurate manner.

[Purpose/Significance] The overall planning and targeted patent information services provided by university libraries play an important role in promoting the management efficiency of national scientific and technological innovation. [Method/Process] By summarizing the mode and process of patent output in universities, this study constructed the model of academic patent supply chain, discussing the information service strategies oriented to university patent supply chain. [Results/Conclusions] The results show that technological trend analysis plays a significant role in improving patent conversion rate. When patent maintenance time is long, patent licensing rate or the average profit value of patent conversion is reduced, scientific evaluation has an effect on improving the quality of patent conversion. When the user's patent awareness or technology acceptance ratio coefficient is contrary to the changing trend of the number of patent applications or conversion, policy feedback measures should be taken to maintain patent quality. Based on the above conclusions, this study puts forward some countermeasures and suggestions from the aspects of expanding the service system, strengthening the data ability and increase exports.

[Results/Conclusions] The inheritance and protection strategies in the process of promoting the development and utilization of rural culture are summarized, which can provide beneficial reference for the development of rural culture.

[Purpose/Significance] Public reading areas in Inner Mongolia are the subject of this study. After an analysis of current cases of cooperation between bookstores and libraries, and exploitation of strength as well as shortcomings, this paper, by referring to successful cases, endeavors to propose tactics for the sustainable development of public reading areas. [Method/Process] Surveys were made via online and telephone interviews, fieldworks, literature research, and analysis of statistics. Setting Hohhot, the capital city of Inner Mongolia Autonomous Region, as the target city, the statistics collected from institutes including Inner Mongolia Autonomous Region Party Committee Propaganda Department, Inner Mongolia Xinhua Publishing Group, The Library of Inner Mongolia Autonomous Region, Hohhot Library, Baotou Library, Puluo Bookstore, Xinhua Bookstore, and Qingcheng Reading Cube. [Results/Conclusions] As is reflected in the survey, the project, with Hohhot city as the center, covers 11 cities and leagues. As for the modes of cooperation, the You-Choose-I-Pay mode dominates, and meanwhile, alternative modes are under development. In the midst of the cooperation, urgent issues that need to be dealt with are financial shortage, restricted opportunities for private bookstores, absence of diversity in cooperation, and underrated advantages of bookstores. To address the problems above, authorities ought to provide further endorsement, including introduction of social forces, adding financial support and balancing the development of related bookstores of various types; the cooperation between the two sides should be deepened by making use of a relevant resource, like new media; the roles of the three, i.e. government, bookstores and libraries, need to be more specific, and integration among the three should be encouraged to better utilize resources provided; constructional plans need be integrated to guarantee the quality of reading materials; inter-section cooperation needs to be enhanced; and the characteristics of local culture and customs are supposed to be preserved as a resource and exploited in a commercialized manner.
