P rogress in science is driven by the publication of novel ideas and experiments, most usually in peer-reviewed journals, but nowadays increasingly just on the internet. We all have our own ideas of which are the most influential journals, but is there a simple statistical metric of the influence of a journal? Most scientists would immediately say Impact Factor (IF), which is published online i...

University rankings generally present users with the problem of placing the results given for an institution in context. Only a comparison with the performance of all other institutions makes it possible to say exactly where an institution stands. In order to interpret the results of the SCImago Institutions Ranking (based on Scopus data) and the Leiden Ranking (based on Web of Science data), i...

We propose two simple indices to classify journals published in the Arabic language and different Arabic researchers. These indices depend on the known impact factor and h-index. The new indices give an easy way to judge the ranking of any journal (output of any researcher) without reference to other non-Arabic journals (output of non-Arabic researchers).

The Journal Impact Factors for 1999 have recently been released and indicate that Thorax has again increased its impact factor, from 2.861 in 1998 to 3.437 in 1999. Thorax has thus further consolidated its position as the highest ranking specialist respiratory journal after the two American Thoracic Society publications. The position of Thorax in terms of impact factor relative to other selecte...

Scholarly journal rankings based on citation data are often met with skepticism by the scientific community. Part of the skepticism is due to the discrepancy between the common perception of journals’ prestige and their ranking based on citation counts. A more serious concern is the inappropriate use of journal rankings to evaluate the scientific influence of authors. This paper focuses on anal...

This study evaluates the utility of a Publication Power Approach (PPA) for assessing the quality of journals in the field of artificial intelligence. PPA is compared with the Thomson-Reuters Institute for Scientific Information (TR) five-year and two-year impact factors and with expert opinion. The ranking produced by the method under study is only partially correlated with citation-based measu...

Finding diagrams, chemical structures, maps or other journal article components is difficult because the articles typically are indexed by topic. Many of these components are all but invisible to standard keyword search. This research describes a method to extract component maps along with metadata from journal articles, and a way to index the maps to make them retrievable by category browse as...

The association between tuberculosis and HIV presents an immediate and gr...
