Knowledge diffusion path analysis of data quality literature: A main path analysis

Xiao, Yu; Lu, Louis Y.Y.; Liu, John S.; Zhou, Zhili - In: Journal of Informetrics 8 (2014) 3, pp. 594-605

This study presents a unique approach in investigating the knowledge diffusion structure for the field of data quality through an analysis of the main paths. We study a dataset of 1880 papers to explore the knowledge diffusion path, using citation data to build the citation network. The main...

The European Union, China, and the United States in the top-1% and top-10% layers of most-frequently cited publications: Competition and collaborations

Leydesdorff, Loet; Wagner, Caroline S.; Bornmann, Lutz - In: Journal of Informetrics 8 (2014) 3, pp. 606-617

The percentages of shares of world publications of the European Union and its member states, China, and the United States have been represented differently as a result of using different databases. An analytical variant of the Web-of-Science (of Thomson Reuters) enables us to study the dynamics...

Impact maturity times and citation time windows: The 2-year maximum journal impact factor

Dorta-González, P.; Dorta-González, M.I. - In: Journal of Informetrics 7 (2013) 3, pp. 593-602

Journal metrics are employed for the assessment of scientific scholar journals from a general bibliometric perspective. In this context, the Thomson Reuters journal impact factors (JIFs) are the citation-based indicators most used. The 2-year journal impact factor (2-JIF) counts citations to one...

Citation and impact factor distributions of scientific journals published in individual countries

Sangwal, Keshra - In: Journal of Informetrics 7 (2013) 2, pp. 487-504

The distributions of citations L, two- (IF2) and five-year impact factors (IF5), and citation half-lives λ of journals published in different selected countries are analyzed using Langmuir-type relation: yn=y0 {1−αKn/(1+Kn)}, where yn denotes Ln, IF2n or IF5n of n-ranked journal, y0 is the...

PageRank variants in the evaluation of citation networks

Nykl, Michal; Ježek, Karel; Fiala, Dalibor; Dostal, Martin - In: Journal of Informetrics 8 (2014) 3, pp. 683-692

This paper explores a possible approach to a research evaluation, by calculating the renown of authors of scientific papers. The evaluation is based on the citation analysis and its results should be close to a human viewpoint. The PageRank algorithm and its modifications were used for the...

Family-tree of bibliometric indices

Kosmulski, Marek - In: Journal of Informetrics 7 (2013) 2, pp. 313-317

Standard bibliometric indices were re-defined using a generalized concept of “successful paper”. A family-tree based upon the new definitions provides new insights into the relationships between the standard indices, and empty boxes in the family-tree may inspire design of new indices.

Comparing all-author and first-author co-citation analyses of information science

Zhao, Dangzhi; Strotmann, Andreas - In: Journal of Informetrics 2 (2008) 3, pp. 229-239

Although it is generally understood that different citation counting methods can produce quite different author rankings, and although “optimal” author co-citation counting methods have been identified theoretically, studies that compare author co-citation counting methods in author...

An extension of the h index that covers the tail and the top of the citation curve and allows ranking researchers with similar h

García-Pérez, Miguel A. - In: Journal of Informetrics 6 (2012) 4, pp. 689-699

Citation curves for researchers with the same h index can vary greatly in the heaviness of their top (excess citations to core papers) or the heaviness of their tail (citations to non-core papers), revealing quantitative differences across researchers. Also, promotion to the next higher h...

Journal weighted impact factor: A proposal

Habibzadeh, Farrokh; Yadollahie, Mahboobeh - In: Journal of Informetrics 2 (2008) 2, pp. 164-172

The impact factor of a journal reflects the frequency with which the journal's articles are cited. It is the best available measure of journal quality. For calculation of impact factor, we just count the number of citations, no matter how prestigious the citing journal is. We think that impact...
