J. A. EVANS’S REPORT “ELECTRONIC PUBLICATION AND THE NARROWING OF SCIENCE AND scholarship” (18 July, p. 395) suggests that (i) the average age of citations to scientific papers dropped over the years as more electronic papers became accessible and (ii) the citations are concentrated on a smaller proportion of papers and journals. Such conclusions are not warranted by Evans’s data. To measure th...

The importance of a research article is routinely measured by counting how many times it has been cited. However, treating all citations with equal weight ignores the wide variety of functions that citations perform. We want to automatically identify the subset of references in a bibliography that have a central academic influence on the citing paper. For this purpose, we examine the effectiven...

The dynamic nature of citation networks makes the task of ranking scientific articles hard. Citation networks are continually evolving because articles obtain new citations every day. For ranking scientific articles, we can define the popularity or prestige of a paper based on the number of past citations at the user query time; however, we argue that what is most useful is the expected future ...

A number of new metrics based on social media platforms--grouped under the term "altmetrics"--have recently been introduced as potential indicators of research impact. Despite their current popularity, there is a lack of information regarding the determinants of these metrics. Using publication and citation data from 1.3 million papers published in 2012 and covered in Thomson Reuters' Web of Sc...

We evaluate what distinguishes a highly cited Interfaces paper from other Interfaces papers that are cited less often. Citations are used to acknowledge prior relevant research, to document sources of information, and to substantiate claims. As such, citations play a key role in the evolution of knowledge. More recently, citations are also being used to quantify the impact of papers and journal...

Humanities and Social Sciences (HSS) increasingly absorb knowledge from Hard Sciences, i.e., Science, Technology, Agriculture and Medicine (STAM), as testified by a growing number of citations. However, whether citing more Hard Sciences brings more citations to HSS remains to be investigated. Based on China's HSS articles indexed by the Web of Science during 1998-2014, this paper estimated two-...

The goal of this paper is to find relevant citations for clinicians' written content and make it more reliable by adding scientific articles as references and enabling the clinicians to easily update it using new information. The proposed approach uses information retrieval and ranking techniques to extract and rank relevant citations from MEDLINE for any given sentence. Additionally, this syst...

OBJECTIVES This study analyzes and describes the literature of addictions treatment and indexing coverage for core journals in the field. METHODS Citations from three source journals for the years 2008 through 2010 were analyzed using the 2010 Mapping the Literature of Nursing and Allied Health Professions Project Protocol. The distribution of cited journals was analyzed by applying Bradford'...

should not contain references unless absolutely essential; any such references must be given in full within the text of the abstract and will be included in the 250 word limit. Unpublished results and personal communications should not be in the reference list, but may be mentioned in the text (personal communications only with the express consent of the communicator) if they are essential. Mec...

Articles from open access and local journals are important resources for research in Korea and the usage trends of these articles are important indicators for the assessment of the current research practice. We analyzed an institutional collection of published papers from 1998 to 2014 authored by researchers from Seoul National University, and their references from papers published between 1998...
