Title: | Theory of the topical coverage of multiple databases | Authors: | EGGHE, Leo | Issue Date: | 2013 | Source: | JOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE AND TECHNOLOGY, 64(1), p. 126-131. | Abstract: | We present a model that describes which fraction of the literature on a certain topic we will find when we use n(n=1,2,...)databases. It is a generalization of the theory of discovering usability problems. We prove that, in all practical cases, this fraction is a concave function of n, the number of used databases, hereby explaining some graphs that exist in the literature. We also study limiting features of this fraction for n very high and we characterize the case that we find all literature on a certain topic for n high enough. | Keywords: | coverage; multiple databases; usability problems | Document URI: | http://hdl.handle.net/1942/14336 | ISSN: | 1532-2882 | DOI: | 10.1002/asi.22766 | ISI #: | 000323384600010 | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2014 |
