Abstract： [Purpose/significance] Considering the inconsistency among the existing empirical findings of influencing factors of knowledge sharing intensions and behavior in online community, the related empirical researched are reviewed and re-analyized.[Method/process] After collecting the related empirical researches, this meta-analysis method is used to identify the determinants of individuals knowledge sharing intentions and behaviors in online communities. Moreover, by means of heterogeneity test and group analysis, this paper also explores the moderating factors affecting the effectiveness of different factors on knowledge sharing behavior, which caused the inconsistency among them.[Result/conclusion] This study concluded that 10 and 14 variables identified in this paper positively contribute to knowledge sharing intentions and behavior, respectively. Among all these antecedents, altruism and attitude toward knowledge sharing are the two strongest factors influencing on the knowledge sharing intention. And outcome expectation, common language, subjective norm and identify have the strongest relationship with knowledge sharing behavior. It was indicated as well that community types and research contexts are identified as two moderators of knowledge sharing intention or behavior and its factors, which can partially explain the inconsistentcy problem. By combing and identifying the antecedents and their moderating factors of knowledge sharing intentions and behavior, this meta-analysis study can be a guidance for online community managers and provide a better theoretical basis for follow up researches in this field.

Abstract： [Purpose/significance] The improvement of public cultural service efficiency is an important part of the construction of public cultural service system. Constructing the evaluation system of public cultural service quality from the perspective of user perception is a supplement to the existing theoretical research on service efficiency.[Method/process] Based on the principles of equalization, adaptability and the nature and characteristics of public cultural services, this study constructs a user evaluation model for the quality of public cultural services, and uses confirmatory factor analysis and path analysis to test the reliability and structural validity of the scale.[Result/conclusion] It is found that the user's evaluation of public cultural service quality consists of four dimensions:tangibility, transparency, relations and suitability, and the user's perception level of these four dimensions have a significant positive impact on their satisfaction level. The model has good reliability, validity and goodness of fit. It can provide reference for follow-up research and specific practice.

Abstract： [Purpose/significance] This paper comprehensively uses qualitative and quantitative methods to analyze and compare the innovative features and expression paradigms of Chinese and foreign information science papers in recent years, thus revealing the innovative characteristics of papers in the field of information science, discovering the knowledge relationship within the innovative sentences, and conducting a more fine-grained analysis of the innovation of the papers, which provides conditions for the discovery and utilization of innovations in the research field, and at the same time, enriches the ways of innovation monitoring of research papers and promotes scientific research innovation.[Method/process] Starting from the sentence-level innovative identification, two kinds of information science journals in Chinese and English are selected as samples, and the methods of NLP and machine learning are used to the process of information extraction and classification. This paper extended the extraction of innovative sentences from the existing abstract to the full text, moreover made full use of sentence structure and syntactic features to identify innovative content in the field, and explored the characteristics of Chinese and foreign information science papers in terms of innovation objects, themes, categories, etc., meanwhile made a comparative analysis. Finally, through qualitative analysis of the automatic classification of document collections, the paper summarized the expression paradigms of the innovation of Chinese and foreign papers.[Result/conclusion] From the expression of innovation points, the distribution of innovative sentences in Chinese and foreign information science papers is basically the same. The expression of innovation in foreign papers is richer. In terms of the characteristics of innovation, the innovation topics of foreign information science journals are concentrated, while the Chinese ones are diversified and scattered. The innovation of specific methods is a hot spot in the field of information science in recent years. The innovation characteristics of both Chinese and foreign information science journal papers reflect the results of applied research and empirical research are richer, while the trend of theoretical innovation is slow.

Abstract： [Purpose/Significance] The main approach adopted in most information retrieval systems currently is to present the search results list linearly based on the relevance score. Although existing researches have theoretically criticized the limitations of this approach, proposing that there is mutual influence between the document previously examined and read, there is no empirical study to further investigate the contextual factors affecting the order effect of relevance judgment. [Method/Process] In response to this question, this paper adopted the 2X2X2 inter-subject experiment method by recruiting 80 subjects. Each subject was required to complete 4 experimental tasks with different topics. Data was collected by questionnaires before and after each experimental task was completed. In order to explore the order effect of relevance judgment and the influence of inter-document relationships as well as the document presentation types as contextual factors, the collected data was analyzed using various methods, such as chi-square test, law of total probability violation, QQ equation, etc. [Result/Conclusion] The research results confirm that the judgment of relevance can be affected by the presentation order of the documents and this effect is different according to the relationships between documents and document presentation types. Specifically, compared to documents with complementary relationships, the order of documents with contradictory relationship is more likely to influence the relevance judgment. In addition, compared with the full text, the order of the presentation of literature snippets is more likely to affect the relevance judgment. Although this paper has its limitations, the research conclusions obtained have certain theoretical, practical and methodological enlightenment.
