The increasing number of scientific journals, especially over the last 20 years, created the need for methodologies based on simple metrics, to accurately capture the “quality” of those journals and their impact on the scientific community. Especially in the case of journals from the field of forestry, relatively little work has been conducted on providing valid journal classifications. In this...

Journals and their citation relations are abstracted into journal citation networks, basing on CSTPC journal database from year 2003 to 2006. The network shows some typical characteristics from complex networks. This paper presents the idea of using motifs, subgraphs with higher occurrence in real network than in random ones, to discover two different citation patterns in journal communities. A...

In this paper we show that the measure of diffusion introduced by Ian Rowlands called the Journal Diffusion Factor (JDF) is highly negatively correlated with the number of citations, leading highly cited journals to get a low JDF, whereas less cited journals gets a high JDF. This property reduces the utility of the JDF as a tool for evaluation of research influence. We present a new definition ...

A citation analysis of core library and information science journals was conducted to identify factors associated with subjective rankings of a journal's value in promotion and tenure decisions. Prestige rankings from a 1982 survey of ARL directors and library school deans were correlated with nine citation measures: total citation count, impact factor, immediacy index, references per paper, Pr...
