Title: | A model for the size-frequency function of co-author pairs | Authors: | EGGHE, Leo | Issue Date: | 2008 | Publisher: | JOHN WILEY | Source: | JOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE AND TECHNOLOGY, 59(13). p. 2133-2137 | Abstract: | Lotka’s law was formulated to describe the number of authors with a certain number of publications. Empirical results [S.A. Morris and M.L. Goldstein. JASIST 58(12), 1764-1782, 2007] indicate that Lotka’s law is also valid if one counts the number of publications of co-author pairs. This paper gives a simple model proving this to be true with the same Lotka exponent if the number of co-authored papers is proportional to the number of papers of the individual co-authors. Under the assumption that this number of co-authored papers is more than proportional to the number of papers of the individual authors (to be explained in the paper), we can prove that the size-frequency function of co-author pairs is Lotkaian with an exponent that is higher than the one of the Lotka function of individual authors, a fact that is confirmed in experimental results. | Keywords: | size-frequency function; co-author pairs; Lotka | Document URI: | http://hdl.handle.net/1942/8488 | ISSN: | 1532-2882 | DOI: | 10.1002/asi.20900 | ISI #: | 000260484000009 | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2009 |
