Due to the rapid development of visualization tools and technologies, the image information plays in the life of society a more and more large role in the course of time. There are widespread different image search and display systems which develop and could be integrated in various information systems. Long ago, many sections had been separated from the fundamental sphere of image information processing as independent directions with specific scientific objectives, such as computer graphics, computer vision, digital photography and others. The tendency to separation of new directions intended for different problems solving persists still, what is confirmed by the enormous annual number of publications. A wide variety of software products can meet the needs practically of any specific problem. But in present variety of image information processing it is possible to separate some general tendencies and some main central problems, which solving determines the image quality and the information systems operation evaluated by ultimate consumer.

<正>One of the problems emerged at the printing stage is the colors mismatch at printing on various digital printing devices and especially on digital printing machines(DPM).This is usually due to the fact that in different DPM’s are used the color-formers with different spectral compositions,and different color management software. 相似文献

Open Access and the Developing World 总被引：2，自引：0，他引：2

Till about 15 years ago, almost all information exchange among scientists and scholars was mediated by print and even then researchers in the developing countries were at a great disadvantage as their libraries did not have the resources to subscribe in comparison with even a small fraction of journals libraries in advanced countries. But the Internet and the World Wide Web initially exacerbated the gap between the rich and the poor countries, as many poor countries were slow to acquire these technologies and the infrastructure (especially bandwidth). Soon it became clear that thanks to these technologies we now have the unprecedented opportunity of having a level playing field in the matter of accessing scientific and scholarly information. Transforming this opportunity into reality is entirely in the hands of the researchers themselves. Imagine a world where every scientist places his/ her research papers, which (s)he wants to give away so others can read and make use of, in a public archive. Anyone anywhere in the world, of course having an Internet connection, can access, download, and read those papers. This is a win-win situation for all: the reader gets to read what he wants to read at very little cost; the author gains greater visibility for his work and the work reported is likely to have greater impact than if it were to be made available only through a toll-access journal. Although the logic is so simple, in reality such archives were not coming up for a very long time. In spite of the fact that computer scientists and physicists had shown about 15 years ago the great advantages of such archives. Recent studies by Alma Swan and others have shown that a very large proportion of scientists are not aware of open access and therefore what we need is focused advocacy. Even among those who know of OA, many are not depositing their papers in archives but say they would if they are asked by their bosses or their funding agencies. Clearly the ball is in the court of scientists and policy makers. OA is especially advantageous to the developing countries as the current access to literatures is poorest in these countries. 相似文献

文献推荐系统：提高信息检索效率之途 总被引：2，自引：0，他引：2
Traditional Information Retrieval (IR) systems have limitations in improving search performance in today’s information environment. The high recall and poor precision of traditional IR systems are only as good as with the accuracy of search query, which is, however, usually difficult for the user to construct. It is also time-consuming for the user to evaluate each search result. The recommendation techniques having been developed since the early 1990s help solve the problems that traditional IR systems have. This paper explains the basic process and major elements of document recommender systems, especially the two recommendation techniques of content-based filtering and collaborative filtering. Also discussed are the evaluation issue and the problems that current document recommender systems are facing, which need to be taken into account in future system designs.

Robert van Gulik＇ s Works on Ancient Chinese Sexual Life： On Material Culture Per-spective
famous Dutch sinologist Robert van Gulik, who wrote Erotic Colour Prints of the Ming Dynasty and Sexual Life in Ancient China, had opened a mysterious door of Chinese sexual culture. However, people seldom notice the fetish tendency in his original and groundbreaking researches. The fact is, besides using erotic colour prints to knock the door of ancient Chinese sexual culture in these two books, especially in the first one, Gulik also paid at-tention to sex toys, sex medicines, underclothes, beddings and other sex aides, and investigates them in depth. 相似文献

Because of its commitment to keeping the digital contents accessible, institutional repository plays an important role in the long-term preservation of intellectual output of the institution. However, digital preservation in institutional repository is faced with severe legal issues, especially the intellectual property problems. This paper focuses on the copyright issues involved with long-term preservation of digital resource in institutional repositories. It begins with a brief introduction to the relationship between the institutional repository and digital preservation. Based on this background information, the paper analyzes the related laws and regulations in China that affect the long-term preservation of digital resource in institutional repository. Then the authors discuss in details what kind of the copyright risk there may be, if we realize the long-term preservation of digital resource in institutional repositories. There may be different legal hazards, according to the various types of the digital output collected by institutional repository. The paper ends up with several suggestions to avoid the legal risk in digital preservation of institutional repository. Firstly, to utilize fair use is a feasible way. Secondly, also most safely, is to get the permission from the copyright owner. This is involved in the long-term preservation contract and open license. 相似文献

现行期刊的评价指标以正向评价指标为主。为探究期刊的反向评价指标,研究与高被引论文相对应的零被引论文的占比情况与期刊影响力的关系,基于Web of Knowledge数据库中的经济学学科发文量位居前10位的期刊所发表的论文在2-6年后的零被引率,并通过相关分析探究其与JCR 2012年期刊评价指标的相关关系,包括影响因子、总被引频次、5年影响因子和h指数等指标,并探究其变化趋势与时间窗口间的关系。研究结果表明：期刊零被引率用于期刊反向评价是合理的,对于经济学这种综合实力较强的学科,时间窗口定为2-3年更为合理,随着年限的变长,论文零被引率与期刊的综合实力的关系越来越弱。 相似文献

篇均来源期刊标准影响(SNIP)为荷兰学者Moed教授于2010年提出的全新期刊评价指标,旨在对不同主题领域的期刊影响力进行评价,为验证这一评价指标在期刊评价实践中的效用,利用SPSS18.0数据统计分析软件对Scopus数据库中24种外文期刊的SNIP与SJR、h指数以及影响因子进行实证对比分析;以CSSCI为来源数据库统计分析国内6种图书情报学期刊的IF值与SNIP值。分析结果证明,SNIP与其他3个指标之间存在较强的相关性,在期刊评价实践中具有可行性。 相似文献

选取中国科技论文与引文数据库中2003—2012年的论文及引文数据,以综合大学学报类和医学综合类期刊的首篇文章为例,从单篇论文评价的角度探讨首篇文章(同行评议质量较高)与同期的总体论文、高h指数论文、高被引论文之间的关系。结果发现:相比同期的其他论文,期刊的首篇文章具有更高的影响力,论文的h指数均值及篇均被引都高于前者;期刊的首篇论文中,38%同时为当期论文中的h指数最高论文,10%为当期论文中的被引频次最高论文,定量评价的高质量论文与同行评议的高品质论文——首篇文章,具有较好的重合度。值得注意的是,这种重合度随着时间的推移在不断增长。 相似文献
