BACKGROUND Measures of research productivity are increasingly used to determine how research should be evaluated and funding decisions made. In psychiatry, citation patterns within and between countries are not known, and whether these differ by choice of citation metric. METHOD In this study, we examined publication characteristics and citation practices in articles published in 50 Web of Sc...

We established in an earlier study that articles listed at or near the top of the daily arXiv:astro-ph mailings receive on average significantly more citations than articles further down the list. In our earlier work we were not able to decide whether this positional citation effect was due to author selfpromotion of intrinsically more citable papers or whether papers are cited more often simpl...

Abstract The citation graph is a computational artifact that widely used to represent the domain of published literature. It represents connections between works, such as citations and authorship. Among other things, supports computation bibliometric measures h-indexes impact factors. There now an increasing demand we should treat publication data in same way conventional publications. In parti...

Retracting published scientific articles is increasingly common. Retraction is a self-correction mechanism of the scientific community to maintain and safeguard the integrity of scientific literature. However, a retracted article may pose a profound and long-lasting threat to the credibility of the literature. New articles may unknowingly build their work on false claims made in retracted artic...

Author searching is traditionally based on the matching of name strings. Special characteristics of authors as personal names and subject indicators are not considered. This makes it difficult to identify a set of related authors or to group authors by subjects in retrieval systems. In this paper, we describe the design and implementation of a prototype visualization system to enhance author se...

Bodies of information available through the Internet, such as digital libraries and distributed file-sharing systems, often form a self-organizing networked information space, i.e. a collection of interconnected information entities generated incrementally over time by a large number of agents. The collection of electronically available research papers in Computer Science, linked by their citat...

Who among the many researchers is most likely to usher in a new era of scientific breakthroughs? This question is of critical importance to universities, funding agencies, as well as scientists who must compete under great pressure for limited amounts of research money. Citations are the current primary means of evaluating one’s scientific productivity and impact, and while often helpful, there...
