Abstract:
We present a method for mapping the content of a text collection. This
method uses linguistic analysis to relate terms extracted from the texts
and clusters them into thematic topics mapped onto a 2D space. While the
graphic display of domain topics is useful for several information-driven
tasks, the focus of the paper is more on the comparison of journal ranking
by productivity (number of published papers in the collection) and by
content representativity (ranking by number of terms and clusters). The
results show that the two rankings are not identical, thus pointing to
possible discrepancies between pure productivity and terminological
density. (c) 2005 Elsevier Inc. All rights reserved.
