Abstract： [Purpose/significance] An in-depth systematic analysis of information encounter behavior can promote academic innovation in this field and application innovation in related information services.[Method/process] Using CNKI and Web of Science as data sources, a systematic review method was used to analyze the most representative 41 literatures in the field. In the research section of the knowledge vein, this paper systematically analyzed and summarized the theoretical models, research methods and influencing factors. In the forefront perspective, the process of encountering information is broken down into three stages:before encounter, during encounter, and after encounter. Then, the paper summed up the study of encountering follow-up behavior.[Result/conclusion] Information encounter behavior is the result of the combined effects of information, individuals, technology, and the environment. The use of encounter information is currently a research hotspot. Research on information encounter based on the information search process chain, research based on the mobile Internet, research based on objective data, and cross-discipline research are hot topics that are feasible in the future.

Abstract： [Purpose/significance] Empirical research is an important part of users' online health information help-seeking behaviour research, and its in-depth analysis can promote the application innovation and pattern innovation of online health information service. [Method/process] This paper takes CNKI and Web of Science as the data source to obtain the representative research documents. Systematic review method is used to comb the related empirical research literature of users' online health information help-seeking behaviour both at home and abroad. [Result/conclusion] Existing studies have initially formed a framework of knowledge systems. However, there are still many research gaps. The influencing factors mainly include internal factors (help-seeking items, help-seeker factors), external factors (information environment, social environment, aid provider factors), mediators (help-seeking demands, cognitive factors), and moderators (demographic factors). In the future, focusing on research foundation, mining influencing factors, paying attention to outcome variables, and promoting data-driven research will be the focus and hotspot.

Abstract： [Purpose/significance] Intermittently discontinuous behavior is an important part of the passive behavior of social network users. This paper makes an analysis of the research results at home and abroad, systematically sorts out its knowledge system and key issues of research in this field, and forecasts the future research trend accordingly, which can provide some reference for the follow-up academic research.[Method/process] With CNKI and Web of Science as the data sources, this paper obtains 54 representative research related to this fields through keywords retrieval, tracing retrieval and subject analysis, adopts the method of systematic review to integrate knowledge base through three key issues, including research topic, research theory and research method, and constructs the framework of normative research process based on this.[Result/conclusion] The study of users' intermittently discontinuous behavior in the context of social network is in the initial stage, and a large space remains for further study in terms of the subdivision degree of research topics, the richness of theory models and the diversity of research methods. Based on the interdisciplinary perspectives of information science, psychology, sociology, journalism and communication, it will be a future research trend to deeply explore the influencing factors and formation mechanism of social network users' intermittently discontinuous behaviour from the perspectives of two-way balance of promoting factors and inhibiting factors as well as comprehensive effect of external social environment and psychological and emotional experience.

Abstract： [Purpose/significance] In view of the problem that it's difficult for researchers to find valuable information from large amounts of scientific and technological information in the Web, this paper constructs a comprehensive calculation method for information value. It can calculate the information value of Web technology information and help researchers find Web technology information of information value quickly and accurately.[Method/process] Taking overall consideration of the external feature and textual semantic feature of the information, this paper used deep learning (pretrained language model) BERT to construct information value calculation model based on the textual semantic feature, used the predictive output of the deep learning model to complete the scoring, and combined the original calculation method of the external feature of the information to get the final information value score.[Result/conclusion] The experimental results show that the information value calculation model based on the textual semantic feature can rank the information to different levels according to their information value score, which makes up for the problem of poor star differentiation in the original calculation method only based on the external feature of the information. And the final comprehensive evaluation results show that the information value calculation model proposed in this paper can also meet the needs of researchers in the practical application.

Abstract： [Purpose/significance] With the development of digitization and informatization, digital resources are playing an increasingly important role. Understanding the databases usage characteristics of faculties will be beneficial to optimize the construction of digital resources and promote the construction of "double first-class" universities. [Method/process] This paper selected Fudan University Library (FUL) as the research object to explore the relevance of databases utilization in library, subjects and facultiesthrough the methods of questionnaire survey, social network and cluster analysis by Leiden algorithm. [Result/conclusion] The results indicate that the homogeneous departments and databases are formed a cluster, the evolution of interdiscipline promotes the usage of specialized databases by the researchers from other major. In the future construction of E-resources, libraries can optimize the procurement of E-resources and discipline service according to the combination of cluster characteristics of disciplines and departments in the utilization of E-resources, and the statistical result based on COUNTER.

Abstract： [Purpose/significance] The status and the historical process of emotion research in the field of Library and Information Science (LIS) were analyzed systematically, to identify the core authors and papers on the scope of the topic, summarize related research framework and characteristics, and anticipate the future research trend.[Method/process] Based on the literature of LIS emotion research in the databases of Web of Science, LISA and Google Scholar, the citation data was mined and analyzed by HistCite, and content analysis method was used to build the emotion research framework.[Result/conclusion] The emotion research in LIS is in a period of rapid development, the emotion research of human-computer interaction, IT use and information behaviors are the directions that LIS scholars pay more attention to them, and users' emotion tendency identification in the social network environment is a hot research direction. The emotion research in LIS still has problems such as hysteretic theoretical development, mixed terminology and classification system that need to be broken through.
