Title
Defining subject collections for informetric analyses : the effect of varying the subject aboutness level
Source
Scientometrics. 41(1998) nos.1/2, S.209-223
Year
1998
Abstract
Examines how several commonly measured properties of subject literatures vary as an important factor in the compilation of subject collections (the amount which a document 'says' about a subject) is varied. This document property has been expressed in formal terms and given a simple measure for the one subject examined, the research topic of Bradford's law of scattering. It is found that lowering the level of subject aboutness required for admission to a collection produces a large increase in the size of the collection obtained, and an appreciable change in some size related properties
