Most Productive Authors in JASIST

with one comment

Timeframe: Dec 2001 (JASIST vol 52, No. 14) – July 2011 (JASIST vol 62, No. 7)

Two types of counting method are used:

  1. Whole count: Each author receive a credit with a count of 1.
  2. Fractional count: Here, if a publication is authored by N number of authors, each author receive credit with a count of 1/N.

5 Years after “Knowledge management: another management fad?”

with 2 comments

In 2000, Ponzi and Koenig wrote a paper titled Knowledge management: another management fad? with the following abstract.


Knowledge management is a subject of a growth body of literature. While capturing the interest of practitioners and scholars in the mid-1990s, knowledge management remains a broadly defined concept with faddish characteristics. Based on annual counts of article retrieved from Science Citation Index, Social Science Citation Index, and ABI Inform referring to three previous recognized management fad, this paper introduces empirical evidence that proposes that a typical management movement generally reveals itself as a fad in approximately five years. In applying this approach and assumption to the case of knowledge management, the findings suggest that knowledge management is at least living longer than typical fads and perhaps is in the process of establishing itself as a new aspect of management. To further the understanding of knowledge management’s development, its interdisciplinary activity and breadth are reported and briefly discussed.

Ponzi and Koenig used article counting technique where the article counts were retrieved from Science Citation Index, Social Science Citation Index and ABI Inform. They counted the number of articles from 1991 to 2001 with the following result.


So, I was curious to know how the knowledge management field has evolved in the past 5 years from 2002 to 2006. Hence I retrieved article counts from both Science Citation Index and Social Science Citation Index (not ABI Inform). The result is as follows:


So, it can be seen that Ponzi and Koenig’s finding still holds now. However, it will be interesting to see whether the number of articles on knowledge management will stabilize around 500 (Article counts in 2007 as per 28 June 2007 is 153).

How to determine the most productive author?

with one comment

There are some most commonly used methods to count for an author’s productivity, namely:

  1. First author counting: Only the first author receives the credit with a count of 1, other authors do not receive any credit.
  2. Total author counting: Each author receive a credit with a count of 1.
  3. Fractional counting: Here, if a publication is authored by N number of authors, each author receive credit with a count of 1/N.

Besides these three methods, there are also different methods such as proportional counting, pure geometric count, Noblesse oblige, etc which can be seen here.

The Scientometrician

leave a comment »

Schubert A, Braun T, Small H, Sweeney E, and Narin F. Four out of the five authors were the recipient of Derek John de Solla Price award. Sweeney E is the only anomaly, and I couldn’t find information about him either. So, if you know about him, please leave a comment.

The following information about the other four authors are taken from the ISSI website.

Schubert A – András Schubert (Hungary) received the award in 1993. He is Senior Scientist at the Institute for Science Policy Research, Hungarian Academy of Sciences in Budapest (Hungary). and also the Editor of the journal Scientometrics.

Braun T – Tibor Braun (Hungary) received the award in 1986. He is director of the Information Science and Scientometric Research Unit (ISSRU) at the Hungarian Academy of Sciences. He is also Professor of Chemistry at the Loránd Eötvös University. He is the Editor-in-Chief of the journal Scientometrics since its first appearance in 1978.

Small H – Henry Small (USA) received the award in 1987 together with Vasily V. Nalimov. He is Chief Scientist and Director of Research Service Group at Thomson ISI. Henry Small received several Awards including the JASIS Best Paper Award in 1987, and in 1998, the Award of Merit from the American Society for Information Science & Technology (ASIST). He has been named the sixth President of ISSI for the period of four years in 2003.

Narin F – Francis Narin (USA) received the award in 1988. He established CHI in 1968, an internationally recognized research consultancy specializing in developing evaluation tools and indicators for science and technology analysis. Narin is recognized as one of the world’s leading experts on science and technology analysis. He started with the analysis of science in the 1970s, before developing evaluations of patents in the 1980s and later, in the 1990s, analyzing linkage between science and technology.

So, that’s about some of the top scientometricians.

In relation to my previous post, I found out that Olle Persson has written an article ‘A bibliometric view of Scientometrics‘ using the data until 1999, which also listed the top cited publication in Scientometrics.

Six of the 10 most cited publication were published in the 1980s, three in the 1990s, and only one which was published in the 2000s.

Schubert A, Braun T, Small H, Sweeney E, and Narin F published more than one top 10 most cited publication in Scientometrics.

The next entry will be devoted to introduce the 5 ‘Scientometrician’.

I am just curious why Eugene Garfield did not publish in Scientometrics?

Who’s Who in Conservation Biology—an Authorship Analysis

leave a comment »

Published in: Conservation Biology, 20(3), 2006, 652-657(6)
Authors: Autumn-Lynn Harrison
Affiliation: Department of Ecology and Evolutionary Biology, Long Marine Laboratory, University of California, Santa Cruz, 100 Shaffer Road, Santa Cruz, CA 95060, U.S.A.

The four previous papers have illustrated how scientometrics techniques being applied in the level of journals, fields, as well as countries. Harrison (2006) studied the authorship trends of a specific journal, Conservation Biology, from its inauguration in 1987 to 2005.

Over the 19-years period, there were more than 5,200 unique authors representing almost 1,500 organisations from 89 countries contributing to 2,060 papers. These data were obtained from Thomson Scientific bibliometric records.

Harrison first investigated the 25 most cited papers. It was found that 62 individuals were involved in the 25 papers. From the first author perspective, 21 of them are men and 4 are women.

From the total number of authors, 82.6% of them published only a single paper and only 6 of them published 10 or more papers, namely Dennis Murphy with 13 papers, Joel Berger 12 papers, Philip Hedrick and Mac Hunter with 11 papers, and Tim Clark and Kent Redford with 10 papers. Interestingly, the top 3 most cited papers do not include any of the most productive authors. The three most cited authors were all from Australia, Richard J. Hobbs received 1021 total citations from 5 papers, Chris Margules received 951 citations from 3 papers, and Denis Saunders received 857 citations from the only paper that he published in Conservation Biology. 82.6% of them published only a single paper.

Harrison also found that the number of single-authored papers decreased significantly over the years from 56.7% in 1987 to 17.8% in 2005. While the number of papers with 5 or more authors ranged from 0 in 1987 to 23% in 2005. Overall, the average number of authors per paper increased from 1.6 in 1987 to 3.3 in 2005.

Finally, Harrison investigated the affiliation of the authors. 62% of the total number of institutions contributed only a single paper. The U.S. Department of Agriculture Forest Service with its 63 papers was the most productive, while the University of Florida and University of California, Davis, were the two institutions with the highest number of first authors with 41 and 40.

A Bibliometrics Analysis of Physics Publications in Korea, 1994-1998

leave a comment »

Published in: Scentometrics, 50(3), 2001, 503-521
Authors: Mee-Jean Kim
Affiliation: Department of Library and Information Science, Jeonju University, Wansan-Gu, Chonju (Korea)

Kim (2001) conducted a research in the same level of aggregation as Cano, which was a specific discipline. However, Kim focused more on the research performance of the authors, which in this case were Korean physicists. Research publications data from 1994 to 1998 produced by Korean physicists were collected from the Science Citation Index CD-ROM Database.

Korean Physical Society and other physical society related in Korea published more than 10 journals in either English or Korean. However, Science Citation Index only included two Korean-published journals, namely Journal of the Korean Physical Society and Bulletin of the Korean Chemical Society.

A total of 4,665 publications produced by Korean physicists or researchers affiliated with physics departments or laboratories were found. These publications were spread over 224 journals produced by 19 different countries. US journals accounted for 37.5% while, followed by Korean and Dutch journals which accounted for 22.0% and 20.1% respectively. There were 33 journals where more than 30 papers had been published in the journals. These 33 journals accounted for 77% of the total number of publications. The top journal, Journal of the Korean Physical Society, accounted for 21.6% of publications.

Out of the 4.665 publications, 31.9% were authored collaboratively by Korean physicists or researchers with other researchers from other countries. Kim also noted that most Korean-authored papers were more likely to be published in Korean, Japanese, or UK journals, while internationally collaborated papers had a tendency to be published in German, Dutch or Swiss journals.

Kim identified the top 15 Korean institutions with more than 100 publications. These top 15 institutions contributed 86.4% of the total publications, with Seoul National University, Korea Advanced Institute of Science and Technology, and Korea University as the top 3 institutions.

Kim further investigated the impact of the publications by looking at the Journal Impact Factor (JIF) of the journals where the papers were published and also at the citation rates of the papers. First, 62.7% of the total publications appeared in the journals with a JIF (1998) greater than 1. Both Korean journals, which accounted for 22% of the total number of publications, had a JIF of less than 1. Secondly, based on the first authors of the publications, 18 authorships countries were identified. Kim found that US and French publications tend to get more citations with an average 15.9 and 16.4 citations per paper respectively, while Korean publications averaged 4.0 citations per paper. However, French publications had a significantly higher self-citations rate in comparison with US and Korean publications. 24.6% of the total number of citations received by the French publications was self-citations, whereas for Korea and US, only 14.1% and 8.2% are self-citations. Among the 18 authorship countries, papers authored by China’s researchers were the least cited with an average of 2.2 citations per paper and 25% of the citations received were self-citations.
