电子出版物的著录

电子出版物是信息及网络时代文献信息资源的重要组成部分，对改善现代图书馆的馆藏建设和服务将产生较大的影响。本文主要对电子出版物的著录进行了探讨。     

“地方人士著述”是否地方文献

关于地方文献范围的讨论中,地方人士著述的取舍问题,一直存在分歧.本文主张地方人士著述应当全部收入当地地方文献,并在分析了新中国建立以来各家观点的基础上,提出了界定"地方人士"可以遵循的两个原则,即出生地原则和户籍原则,认可在这两个原则下同一文献同时收于两地地方文献的情况.参考文献10.     

The emergence of China as a leading nation in science

China has become the fifth leading nation in terms of its share of the world's scientific publications. The citation rate of papers with a Chinese address for the corresponding author also exhibits exponential growth. More specifically, China has become a major player in critical technologies like nanotechnology. Although it is difficult to delineate nanoscience and nanotechnology, we show that China has recently achieved a position second only to that of the USA. Funding for R&D has been growing exponentially, but since 1997 even more in terms of business expenditure than in terms of government expenditure. It seems that the Chinese government has effectively used the public-sector research potential to boost the knowledge-based economy of the country. Thus, China may be achieving the (“Lisbon”) objectives of the transition to a knowledge-based economy more broadly and rapidly than its western counterparts. Because of the sustained increase in Chinese government funding and the virtually unlimited reservoir of highly skilled human resources, one may expect a continuation of this growth pattern in the near future.     

Application of machine learning techniques to assess the trends and alignment of the funded research output

Research and development activities are regarded as one of the most influencing factors of the future of a country. Large investments in research can yield a tremendous outcome in terms of a country’s overall wealth and strength. However, public financial resources of countries are often limited which calls for a wise and targeted investment. Scientific publications are considered as one of the main outputs of research investment. Although the general trend of scientific publications is increasing, a detailed analysis is required to monitor the research trends and assess whether they are in line with the top research priorities of the country. Such focused monitoring can shed light on scientific activities evolution as well as the formation of new research areas, thus helping governments to adjust priorities, if required. But monitoring the output of the funded research manually is not only very expensive and difficult, it is also subjective. Using structural topic models, in this paper we evaluated the trends in academic research performed by federally funded Canadian researchers during the time-frame of 2000–2018, covering more than 140,000 research publications. The proposed approach makes it possible to objectively and systematically monitor research projects, or any other set of documents related to research activities such as funding proposals, at large-scale. Our results confirm the accordance between the performed federally funded research projects and the top research priorities of Canada.

SAGA：一种新的船舶搁浅预警模型

随着船舶自动识别系统(Automatic Identification System,AIS)和电子海图信息与显示系统(Electronic Chart Displayand Information System,ECDIS)的出现及普及,使船舶交通管理系统(Ves-sel Traffic Service,VTS)对其辖区的航行船舶进行自动搁浅预警成为可能.针对预警自动化水平较低这一现状,提出搁浅预警(Search Area for Grounding A lert,SAGA)模型,通过判断船舶SAGA领域内最小水深是否满足安全要求来实现船舶搁浅预警.     

Identifying and removing duplicate records from systematic review searches

Objective

The purpose of this study was to compare effectiveness of different options for de-duplicating records retrieved from systematic review searches.

Methods

Using the records from a published systematic review, five de-duplication options were compared. The time taken to de-duplicate in each option and the number of false positives (were deleted but should not have been) and false negatives (should have been deleted but were not) were recorded.

Results

The time for each option varied. The number of positive and false duplicates returned from each option also varied greatly.

Conclusion

The authors recommend different de-duplication options based on the skill level of the searcher and the purpose of de-duplication efforts.
