[Purpose/significance] A systematic review and analysis of the current status of Metaverse research in China and abroad is conducive to accurately grasping the direction of Metaverse development, strengthening basic research about Metaverse, and striving for the leading power to construct Metaverses.[Method/Process] Using the PRISMA method, 262 Metaverse thematic papers collected from Web of Science, ScienceDirect, SpringerLink, Google Scholar, CNKI, WanFang, and Baidu Scholar were employed to organize and answer four research questions on the concept and main features of the Metaverse, core technology and architecture, application industries and cases, and potential effects and empirical evidence.[Result/Conclusion] The results show that:① unlike traditional cognition, the concept of the Metaverse is not ambiguous, but evolves and develops from the individual-level Metaverse to the human-level Metaverse by closely focusing on five core features:virtual, immersive, communion, social, and interactive; ② Metaverses at different levels share a set of technical architecture, in which the core technologies are highly consistent and synergistic, but the overall technical maturity is not high; ③ the application scope of the Metaverse in industries is limited, mainly in tertiary industries, and the cognition and demand for it in secondary and primary industries need to be deepened and expanded; ④ The Metaverse's potential effects are distributed in the five categories of the political, social, economic, technological, and cultural values. Positive effects are unquestionably greater than negative ones, but there are conflicting opinions, and there isn't enough empirical research to back this up. Furthermore, discussing the shortcomings of existing Metaverse research and possible future research directions can provide useful references and insights for further exploration of the Metaverse and related topics.

This paper introduces the connotation of multilingual ontologies which can depict the knowledge expressed in different languages. Then it analyzes the function of multilingual ontologies in improving the cross language information retrieval from aspects of query expansion, semantic annotation, and concept-based indexing. With the examples of EuroWorldNet and Cindor, the paper discusses the key issues of mapping multilingual ontologies. It is considered in the paper that it will be useful to use interlingua to describe concepts and compare the translation of dictionaries so as to link with the words for mapping multilingual ontologies in different languages.

[Purpose/significance] Internet user evaluation has become an important reference index when people choose goods. This paper aims to know the relationship between grade evaluation and review evaluation, to provide ranking and recommendation function in line with the potential grade for these websites which only have review evaluation.[Method/process] Through grasping Douban.com Movie users' comments and using the ROST EA tool for sentiment analysis to get comprehensive sentiment value, then makes correlation analysis with grade evaluation and taking into account the emotional intensity of the comment text, which cause difference of the results. On the basis of this, a regression model is constructed by regression analysis and tested.[Result/conclusion] It turns out that the correlation between them was high and the empowerment of emotional strength has little effect on the results, which indicates we can predict grade by review evaluation. The corresponding regression model is given in this paper.

The paper introduces the main functions of three kinds of academic tag systems as RefWorks, Connotea and CiteULike, and then compares the similarities and differences. It can be found that while RefWorks is a better creator for bibliography, Connotea is good at references organizing, new clue discovering and knowledge sharing, and CiteULike is a free online service for academic papers organization. The author suggests that academic libraries should take the responsibility for educating the users with a roper use of social software.
