Abstract： [Purpose/significance] Based on the feedforward back-propagation artificial neural network, the paper puts forward the evaluation method of WeChat Official Account information dissemination in finance and economics university library, it aims to provide reference for the operation and popularization of the WeChat Official Account of financial university library. [Method/process] According to the characteristics of the information dissemination of the WeChat Official Account in financial university library, starting from the elements and links in the process of information dissemination, this paper constructs an evaluation index system of information dissemination effect from five dimensions: dissemination subject, dissemination content, information carrier, dissemination skill and dissemination object. By collecting the relevant data of Wechat public number of 30 financial and Economic University libraries, the evaluation index system is based on the feedforward BP neural network model. [Result/conclusion] Based on the feedforward BP Neural network, the paper put forward the evaluation method of WeChat Official Account information dissemination effect in financial university library. Then, through empirical research, it was proved that the evaluation method has a good effect on the evaluation of the propagation effect of WeChat, and according to the evaluation results, the countermeasures and suggestions were put forward to promote the communication effect of the WeChat Official Account in finance and economics University library.

Abstract： [Purpose/significance] This study aims to explore the differences between collaborative mode and individual mode of information search on search experience and search interaction, trying to understand the characteristics of collaborative information search from various angles.[Method/process] The experiment is designed based on books interactive retrieval platform (CLEF-Social Book Search). Sixteen independent and eighteen collaborative participants are recruited to the laboratory to complete different types of book search tasks. Users' interactions with the system during search are recorded through the backend server; while their search experience is recorded by questionnaires completed before and after the search. In data analysis, users' interactions and search experience are compared between two search modes.[Result/conclusion] (1) Search experience:Compared with individual searchers, collaborative searchers have better evaluation on experiment system function and higher evaluation on aesthetics, durability, novelty of the system, and participate in the search more intently. However, collaborative searcher felt a bit more frustrated and mentally taxing than individual searchers. (2) Search strategies:Compared with individual searchers, collaborative searchers make more decisions in the goal-oriented task, especially the decision of removing books from bookbag, which indicates collaborative searchers need to sort the books in the later stage. In the open-ended task, collaborative searchers spend more time before each decision than individual searchers, which is probably because of collaborative searcher's higher level of focus and participatory. This study helps understand about collaborative search through comparison with individual search, which may provide inspiration for collaborative search system design.

Abstract： [Purpose/significance] It is of great importance to grasp the current status, hotspots, and frontiers of research on knowledge service mode for understanding knowledge service activities and effectively guiding knowledge service practices.[Method/process] Based on defining knowledge service and knowledge service mode, this paper systematically reviews the research status of knowledge service mode through keyword frequency statistics and co-appearance network analysis. Then, through content analysis, this paper explores and discusses the research hotspots and frontiers of knowledge service mode from four elements of knowledge service.[Result/conclusion] The present research shows an increasing trend at home and abroad, and has several differences between them. Current research hotspots are discussions on innovation-oriented, user-oriented, technology-oriented and domain-oriented knowledge service modes. Future research frontiers will be knowledge service mode in open innovation,knowledge service innovation mode with design thinking, knowledge management mode under big data environment and the application of knowledge service mode in the field of healthcare.

Abstract： [Purpose/significance] In view of the realistic problems of cultural heritage institutions' user service channel blocking,insufficient contact with target users,low utilization rate of collection resources existing in libraries, museums and archives, based on "Internet + traditional collection information service", this paper explores the feasibility of online to offline service mode.[Method/process]The paper uses literature review to analyze the drawback of traditional mode,and O2O mode's application in the field of LAM theoretically, illustrates the present situation of internal cultural heritage institutions' application of O2O service method, puts forward traditional collection O2O information service mode, explains its connotation, elements and forms, and discusses the practical operation and service process.[Result/conclusion]Cultural heritage institutions are adapting to the changes in digital age. The traditional collection O2O information service mode accords with this tendency,and is helpful to user service development and transformation of LAM.

Abstract： [Purpose/significance] Requirement has always been the key to improve service quality and level. Exploring effective knowledge service mode from the perspective of client requirement is of great significance to guarantee the knowledge service quality and improve the service level and influence of think tanks. [Method/process] Through literature review, this paper summarized the types of client requirements for think-tank knowledge service and the knowledge service modes of think tanks. Then a questionnaire survey was used to collect data from two client groups, including government employees and the public. This paper analyzed the clients’ cognition degree, intensity of requirements and service mode selection intention for think tank knowledge services, and analyzed the relationships between client requirements and knowledge service modes of think tanks through partial least squares regression model. [Result/conclusion] The cognition degree of government employees to think tank knowledge service is significantly higher than that of the public. And government employees have a better understanding of party and government think tanks, while the public has a better understanding of university think tanks. The intensity of clients’ requirements for the knowledge services of think tanks from high to low are talent support, policy research, decision-making consultation and public opinion propaganda. Clients’ willingness to choose different knowledge service modes of think tanks is, from high to low, open media, open publication, offline communication and internal cooperation. Moreover, clients’ requirements for various knowledge service modes have a significant positive impact on the different knowledge service modes of think tanks.

Abstract： [Purpose/significance] To further improve the theory of information needs, and optimize network health information service, this paper analyzed the motivation and topic of college students' health information needs in public health emergencies. [Method/process] In this paper, public health emergencies within the scope of China in early 2020 were taken as the context and self-reported information needs of search users were taken as the analysis object. This paper adopted the method of content analysis, open coding and association rules to analyze distribution, evolution and correlation. [Result/conclusion] The study found that college students' health information needs in public health emergencies are balanced by individual and social motivation; the study found that the topic of health information needs in public health emergencies focused on epidemic situation and trend, disease prevention, etiology pathology and diagnosis, government behavior and social phenomena; with the evolution of public health emergencies, the focus topics of health information needs changes steadily; the motivation and topics are significantly correlated; epidemic situation and trend, social phenomena and government behavior are driven by social motivation, while individual motivation mainly drives disease prevention, etiology, pathology and diagnosis.
