Bibliometric analysis of the automatic indexing literature: 1956–2000

摘要

We present a bibliometric study of a corpus of 839 bibliographic references about automatic indexing, covering the period 1956–2000. We analyse the distribution of authors and works, the obsolescence and its dispersion, and the distribution of the literature by topic, year, and source type. We conclude that: (i) there has been a constant interest on the part of researchers; (ii) the most studied topics were the techniques and methods employed and the general aspects of automatic indexing; (iii) the productivity of the authors does fit a Lotka distribution (Dmax=0.02 and criticalvalue=0.054); (iv) the annual aging factor is 95%; and (v) the dispersion of the literature is low.
