[Purpose/Significance]Social commerce research presents the characteristics of interdisciplinary studies, because of which ts research perspectives, research methods and research content are in a more decentralized state. This study aims to review the current social commerce research and presents the, analysis of its development and characteristics. [Method/Process] We first obtained Chinese and English journal papers published from 2010 to 2019 from CNKI, CSSCI, SCIE, SSCI databases. We then discussed the current progress and characteristics of social commerce research from time distribution, theme changes, high citation papers, and high-frequency keywords. [Results/Conclusions] We believe that there are still some topics that can be excavated in the study of social commerce: Firstly, we need to further explore such user behavior research topics as user perception and the strategy choices, and business management, technical support and information research in social commerce context. Secondly, the research theory has presented a certain interdisciplinary perspective, and we can find and explain the practical problems in social commerce from the perspective of more subject areas. Thirdly, the applicability of computer science, information science and psychology research methods to the field of social commerce can be discussed and studied.

[Purpose / Signficance] The current competition of comprehensive national strength relies more on fundamental research, and highly cited papers have important significance in the evaluation and analysis of fundamental research. Revealing the differences between China and USA in leading basic research from the perspective of highly cited papers, we provide basic data support for national scientific research management decision-making and institution building. [Method / Process] Based on ESI highly cited papers of China and USA, this article uses bibliometric methods and Y index to analyze the specific features and differences of China and USA among three dimensions—trends of publication, country cooperation and institutional output.[Results / Conclusions] The study shows that: (1) Overall, the highly cited papers of China is 2.99 times that of the American highly cited papers, but the gap is narrowing yearly. At the same time, the low citation frequency and the low proportion of highly cited papers are still the shortcomings that limit Chinese international influence. (2) China and USA are closely cooperating with each other. USA dominates scientific research cooperation, as the proportion of first authors and corresponding authors and leading papers is significantly higher than that in China. (3) Chinese high-output institutions have obvious advantages of corresponding authors, but the output gap between institutions is large. And the American high-output institutions are evenly distributed, and they are characterized by deeper and broader international cooperation and inter-agency cooperation.

[Purpose / Significance] Through the comprehensive and scientific analysis of the patent data of colleges and universities and the literature on the level of patent competitiveness. We will be in a better position to judge the research capability of colleges and universities, and in the meanwhile our analysis has a certain reference value for the development of science and technology of the country. [Method / Process] From the four dimensions of patent quantity, patent value, maintenance ability and R & D potential, a patent data fusion evaluation system of 14 indicators was established, and 25 representative universities in Southeast five provinces (Guangdong, Guangxi, Fujian, Zhejiang and Jiangsu) were analyzed and evaluated by using the evaluation system. [Results / Conclusions] According to the evaluation system, the patent competitiveness was divided into three echelons. The first echelon was composed of eight universities: Zhejiang University, Southeast University, South China University of Technology, Sun Yat-sen University, Nanjing University, Suzhou University, Zhejiang University of Technology and Jinan University. The second echelon was composed of South China Agricultural University, Xiamen University, Nanjing University of Technology, Fuzhou University and South China Normal University, Ningbo University and Nanjing Agricultural University; the rest are the third echelon. The ranking of patent competitiveness of colleges and universities is not completely consistent with that of Wushu list. Some lower-ranking colleges and universities on Wushu list have higher patent competitiveness than those higher-ranking ones. The patent competitiveness of colleges and universities is impacted by their cultural and scientific focus, and not completely related to their comprehensive strength. At the same time, the patent competitiveness is also closely related to the economic strength of the region where colleges and universities are located. For example, of colleges and universities in Jiangsu and Zhejiang are obviously more competitive in patent competitivenesss than those in other regions. However, colleges and universities in Guangdong have slightly insufficient patents patents, while colleges and universities in Jiangsu are not weak in four dimensions. Although colleges and universities in Zhejiang have a large number of patents, the value and maintenance capacity of their patents are still insufficient.

[Purpose / Significance] We redesigned the book borrowing and returning function of the Library APP of Liaoning University of Technology to make the APP operate reasonably and run smoothly.

[Method / Process] The design of foreground on the borrowing APP uses Android Studio as the development tool. The background development tool is Eclipse. The background was applied in the JFinal frame construction. The database is MySQL. MySQL indirectly linked to the Tomcat server. The front ground and background use the C/S pattern. The development language is the Java. The links of background patterns and iconsare of borrowing APP were simplified. [Results / Conclusions] The borrowing APP have been tested on the Android platform and different models of mobile phones. The interface of the borrowing function is clear, the operation is reasonable, and the operation is smooth. The performances of the redesigned APP were superior to those of the current version of our library APP.

[Purpose / Significance] In order to quickly obtain a massive amount of data of land transfer on the Internet, with the help of the current popular method of data collection and analysis-web crawler technology, the new hot spots of rural land transfer in China are excavated and sorted out from the perspective of news and information. [Method / Process] Taking People's Daily as the target web page, we search keywords on the web page and use Python to write and design programs to crawl the news documents of farmland circulation on the web page. and We then use the obtained more than 2 500 pieces of news as data to analyze the status, content and problems of agricultural land transfer by using text analysis methods and drawing Python word cloud diagrams. [Results / Conclusions] Crawling the web news information, through statistical analysis of the collected news content, after hot spot mining, it is found that China is attaching more importance to the transfer of agricultural land and increased publicity in this regard, The construction of agricultural land transfer and precision poverty alleviation, and rural tourism and cooperatives are closely connected with one another. At last we analyze the existing problems in above-mentioned three aspects and make recommendations.
